Non-print equipment & services: Slides

35mm slides – suited for small to very large audiences, dim to no light preferable.Typical problems with slide presentations include:

• Out of focus slides
• Going backwards instead of forwards on remote
• Out of order slides
• Upside down or backward slides
• Slides sticking in projector
• The dumped upside down or lost slide carousel

General tips on operating a slide projector include the following:

• Many of the projectors have a “timer” function. The purpose of the timer is to allow the slides to automatically advance after a specified time. It is important to check this feature and turn it off if you are advancing slides manually via a remote control.
• Two types of slides trays are available for the Ektagraphic projectors, an “80 count” and “140 count” tray. The “80 count” tray is recommended. The “140 count” trays have a tendency to jam in the projector.
• Some projectors have a built-in auto-focus feature. This feature allows slides in similar types of mounts to keep their focus. It is important to manually focus the first slide, then turn-on autofocus. When using slides of various types and thicknesses of mounts do not use the auto-focus feature.

Setting up the projector
Unpack the projector from its case, and set it on the table, cart, or projection stand.

The lens might not be attached. If it isn’t, grasp the front end of the lens barrel and align the teeth on the side of the lens with the notch at the edge of the lens opening on the front of the projector. Do not force the lens into place! The focus knob is spring loaded… pull the knob sideways, towards the outside edge of the projector, and slide the lens into the projector body. Then release the focus knob, which will lock the lens into place.

Examine the back of the projector, and find the power cord.

• Some projectors have two metal pins sticking out from the back, just below the five-pin remote-control socket. In this case, the power cord should be in the carrying case.
• On other projectors, the power cord is hard-wired into the unit, and often stored under a trap-door in the bottom of the projector.

Connect the power cord and plug it into the wall outlet.

Connect the remote control if desired.

To connect the remote control, locate the dot on the top of the round, five-pin connector at the end of the remote control cable. With the dot at the top, plug the remote control into the five-pin socket on the back of the projector. It will only fit one direction.

Note: On a few projectors, there are no frame-advance buttons, and the remote control must be used. Otherwise, the remote control is operational.

Disable the self-timer, if any.

Some projectors have built-in interval timers, operated by a slide switch on the back of the unit. If your projector has one, slide the timer switch to the MANUAL position.

Turn the projector on.

Turn on the projector by moving the power switch to one of the lamp-on positions.

Note: You may get a screenful of light, as some projectors do not have empty-slot shutters.

Attach the slide tray to the projector.

Position the tray with the 0th slide position to the right, as you look at the back of the projector. Notice that the arrow on the top of the projector will cover the notch in the edge of the slide tray.

Advance to the first slide.

Advance to the first slide by pressing the FORWARD button on the remote control, or the push button nearest the front of the projector (if the projector has one).

At this point, you should see your first slide on the screen. You can make some adjustments at this point—

• To raise or lower the image, rotate the foot adjustment knob under the front-center of the projector.
• To straighten a crooked image, rotate the foot adjustment under the rear corner of the projector.
• To focus the image, rotate the focus adjustment knob on the top of the projector.
• If the projector has a zoom lens, you can resize the image by rotating the end of the lens barrel.

Slide show presentation

• To project your slide show, use the FORWARD and REVERSE buttons on the remote control, or the two buttons on the side of the projector.
• To select a particular slide, press and hold the SELECT button on the side of the projector, and rotate the slide tray by hand until the slide you want lines up with the arrow on the top of the projector. When you release the SELECT button, the slide will appear on the screen.
• At the end of the show:
  o Move the power switch to the FAN position.
  o Press and hold the SELECT button, and rotate the tray to the Slide 0 position.
  o Lift the tray off of the projector.

If you need to remove the tray from the projector without moving it to the zero position, use the following procedure:

Use a coin or screwdriver to rotate the screw in the center of the top of the projector. This will release the tray from the top of the projector. Then lift the tray clear of the projector. Be very careful! One of your slides will remain in the projector. Also, the metal pan on the bottom of the tray will not be locked. If it rotates, it can allow other slides to fall out of the t ray. To remove your slide from the projector, press the SELECT button, and it should literally fly out of the opening in the top of the projector. To reset the tray, make sure that the locking ring is in place on the top, then turn the tray upside-down, and rotate the metal pan until it locks into place under the blocked-off zero position.

When you are finished, disassembly of the projector is the reverse of set-up.

• Allow the fan to run until the exhaust air is cool before moving or unplugging the projector.
• Disconnect the projector from the wall outlet, and disconnect the remote control (if you ever connected it in the first place).
• If the carrying case requires removing the lens, do so by sliding the focus knob sideways and sliding the lens straight out of the projector body.
• Pack the projector into its case.

Lamp change
If a lamp blows in the middle of a presentation:

• Leave the projector plugged in while you locate the spare lamp. This cools down the socket which otherwise would be too hot to touch.
• Remove the slide tray from the projector, making a mental note of the slide number that was being shown when the bulb expired. Be sure that the locking ring is secure.
• Hold the tray upside down and rotate the plate on the bottom of the tray so that the slot on the bottom plate lines up with the “0” notch on the plastic tray.
• Unplug the projector and turn it upside down.
• Unscrew the large silver screw that holds the lamp door for the socket and the lamp.
• You should be able to use your fingers. If not, a coin will do the trick.
• Depress the wire that secures the old lamp in position, gently lifting up the on the old bulb at the same time. As you do so the old lamp should come out.
• Remove the new lamp from the box, being careful not to touch the lamp with your bare fingers. Oils from your skin could cause the lamp to burn out prematurely.
• Raise the wire out of the way and place the new lamp in position.
• Lower the wire into position making sure the lamp pins are securely in the socket.
• Secure the wire to the metal clip.

Non-print equipment & services: Occupational health & safety

Electrical safety
Personal injury is generally due to electric shock or burns.

Electric shock
Electric shock occurs when a person becomes part of an electrical circuit and the current flows through their body. A person receives an electric shock by touching a live electrical cable, or by touching equipment which has become ‘live’ due to an electrical fault, lack of maintenance or a short circuit. A person may suffer irreparable damage to their body tissue. A fatal shock is called electrocution.

Electrical burns
Electrical burns are caused by the direct passage of electrical current through the body. A burn can also be caused by direct contact with a hot surface, such as a lamp.

While the surface of the skin may not show evidence of burning, electrical burns may affect deep tissue. Electrical burns are often slow to heal, and medical treatment should always be sought.

Activity
Using a first aid manual such as St. John ambulance’s Australian first aid, write down the first aid steps for managing electrical burns.

MayoClinic. Electrical burns: first aid http://www.mayoclinic.com/health/first-aid-electrical-burns/FA00027

While helping someone with an electrical burn and waiting for medical help, follow these steps:
1. Look first. Don't touch. The person may still be in contact with the electrical source. Touching the person may pass the current through you.
2. Turn off the source of electricity if possible. If not, move the source away from both you and the injured person using a dry nonconducting object made of cardboard, plastic or wood.
3. Check for signs of circulation (breathing, coughing or movement). If absent, begin cardiopulmonary resuscitation (CPR) immediately.
4. Prevent shock. Lay the person down with the head slightly lower than the trunk and the legs elevated.
5. Cover the affected areas. If the person is breathing, cover any burned areas with a sterile gauze bandage, if available, or a clean cloth. Don't use a blanket or towel. Loose fibers can stick to the burns.

Electrical fires
Electrical fires can be caused by overheating of electrical wiring or equipment. You need to know fire alarm and evacuation procedures.

Activity
Write down the fire alarm and evacuation procedures in your organization.

Know who the fire wardens are. Know how the alarm sounds. Know where to exit. Know where to evacuate to. Know what to check. Know what to take. Know who to notify.

First aid
Delay in the rescue and resuscitation of an electric shock victim may be fatal, so the first few minutes are vital. Contact expert help if readily available.

Activity
Using a first aid manual such as St. John ambulance’s Australian first aid, write down the plan of action for rescuing an electric shock or burn victim.

Remove person from danger. Don’t expose anyone else to hazard. Turn off power. Call for first aid. Check for and/or manage burns. Lie person down. Raise person’s legs. Turn on side. Check airway is clear and/or open. Begin resuscitation.

General safety precautions

• Keep equipment in safe working order by regular inspections and a preventive maintenance program.
• Disconnect broken appliances.
• Keep equipment away from water and wet areas.
• Always switch off equipment at the power point before pulling out the plug.
• Don’t overload circuits and fuses by using too many pieces of equipment from one power point. Use a power board with individual switches instead of double adaptors.
• Inspect plugs and electrical cables for damage. Have broken power points replaced by a licensed electrician.
• Keep electrical cords off the floor to reduce damage to cords and risk of tripping.
• Know the location of the main electrical supply or fuse box.
• When replacing fuses and lamps use the correctly rated replacements.
• Take care when replacing a lamp in a projector which has been recently used. The lamp may still be hot. Use a cloth or glove.
• Use trolleys to move heavy or bulky equipment.
• Use trolleys to raise equipment such as projectors to the correct height. Don’t balance equipment on piles of books.
• When setting up rooms with equipment ensure that people can exit easily and quickly. Consider the positioning of equipment, screens and chairs.
• Know the location of fire extinguishers.
• Know the location of fire escapes and emergency exits.
• Use equipment correctly. Follow operational and safety instructions in the manual.
  

Exercise
Complete the following table, listing possible occupational health & safety hazards and the precautions which can be taken. Precautions include safe work practices and hazard reduction procedures.

Hazard	Precaution
Electric shock	Good maintenance of electrical equipment Safe work practices including dry work area, not carrying out unauthorised procedures Power off
Lifting/carrying/moving	Correct lifting procedures Safe work practices including dry work area, not carrying out unauthorised procedures Power off
Bright light	Turn equipment off when not in use Avoid looking at operating light source
Burns (heat lamp)	Let equipment cool down Wear protective clothing
Power cords/cables	Plan equipment layout Tape to floor Good repair

General machine handling hints
Not only do you need to take care of yourself, you also need to protect the equipment you use.
· Follow operational and safety instructions in the manual.

• Use equipment safely and only for its intended use.
• Never force parts of equipment that do not fit or operate easily. However you may need to ‘gentle’ a part – e.g. releasing the Fresnel lens on an overhead projector.
• Don’t drop or knock equipment.
• Wrap power cords around the leg or handle of a table or trolley.
• Do not use a machine unless all parts – e.g. cooling fan – are working properly, as you risk damaging the equipment or software.
• Prevent heat buildup by allowing adequate air circulation – e.g. do not block ventilation slots by placing equipment on a soft surface or by operating it in an enclosed area, such as on a shelf.
• Keep operating instructions in a secure area. If necessary, keep photocopies of operating instructions with equipment.
• Read the manual.
• Always test the equipment before use, and after performing any maintenance tasks – e.g. changing a lamp.
• If you need to replace a lamp, do not touch the glass with bare hands. Use a cloth, glove or the plastic sleeve which comes with the lamp.
• Power cords should be folded loosely and stored in the compartment if the machine has one. If power cords are separate they may be folded loosely and tied to the equipment.
• Do not wrap power cords around equipment unless it is designed to do this (e.g. some overhead projectors).
• Check that all components of a piece of equipment are kept together. Label equipment or case with a list of components and check on issuing and return of equipment.
• Remove batteries from equipment when storing for any time, or if it is to be used routinely with mains (AC) power.
• Make sure equipment is OFF when plugging AC cord into outlet.
• TO disconnect any cord from a machine, grasp the plug (some plugs may need to be turned or pins compressed). Never pull the cord.

Non-print equipment & services: Opaque projectors

Opaque projection is a method of enlarging and displaying nontransparent material on a screen, e.g. pages from books or magazines, maps, etc. It makes a wide range of visual materials available for group viewing. The opaque projector is used to project photographs, drawings, book pages and the like onto screen for group viewing. It performs this function by using a strong 1000 watt incandescent lamp to reflect light off the surface of the material. The image is reflected through a lens onto a screen. As the light is reflected off the material rather than passing through it, opaque projection is classed as an indirect projection system.

Indirect projection is less efficient than the direct projection process used for showing slides, filmstrips, motion picture film and overhead transparencies. Much of the light is absorbed by the material being projected, thus making the screen image dim. The room must be completely darkened to view the material properly.

Advantages:

• Materials such as pictures which lose much in reproduction processes can be viewed naturally.
• Colour can be projected.
• No special preparation of material is required.
• Relatively flat three dimensional objects such as coins, plant leaves, and insect specimens can be projected for group viewing.
• Prints, pictures, etc. can be viewed with minimum damage due to handling by numerous people.
• Student work such as drawings, solutions to math problems, compositions, etc. can be viewed and discussed by a group.
• Tracings and enlargements of printed or pictured materials can be made by projecting onto a blank sheet of paper.

Disadvantages:

• Dim image means the room must be almost completely dark.
• Machine is bulky, heavy, cumbersome to move.
• High wattage lamp generates a lot of heat, making parts of the projector unsafe to touch. The heat may also damage materials being projected if they are exposed too long. Laminated or plastic book covers can bubble or melt, and the glue on paperbound books may melt.
• Pictures must be flat or parts of the image will be out of focus.

Troubleshooting
Problem: No light after flipping switch
Solution: Be sure projector is securely plugged into an electrical outlet.
Check lamp. If burned out, replace it. Since you must push down very hard on the lamp while twisting it, be sure to use a cloth.
Switch may also be defective. If so, have a media technician replace it.

Problem: Line through picture
Solution: The piece of glass between the material and the lamp may be broken. Be sure to replace if with the manufacturer’s glass since this glass has special properties for resisting heat and pressure.

Problem: Glass is broken
Solution: Someone applied too much pressure when loading the material. The material should be snug in the projector – not tight.

Problem: Brown spot appears within projected image.
Solution: The material is beginning to burn. GET IT OUT!

Problem: Image won’t focus, even with lens out all the way.
Solution: Projector is too far from screen, move it closer, or material is not held flat, adjust the height of the platen.

Maintenance
Little maintenance is required.
Clean lens with a soft dry cloth.
Blow off foreign matter or dust if it gets on the mirror inside the projector.
The mirror scratches easily if touched.

Operating instructions

• Plug in.
• Place item to be shown on platen (stage). Place material face up with bottom edge toward screen.
• Use platen lever to raise and lower stage.
• Turn on projector with ON/OFF switch.
• Focus image.
• To enlarge image, move projector away from screen, to make smaller, move projector closer to screen.
• Warning! Because of the heat generated by the bulb, do not leave photos or other paper material on the platen area for too long.

The visual presenter/document camera is an electronic version of the opaque projector. It is a video camera mounted on a copy stand, pointed downward at documents, flat pictures, or graphics. The image may be projected onto a screen using a data/video projector.

Non-print equipment & services: Cassette tapes

The earliest analog cassettes used ferric oxide tape, now referred to as “normal” or “Type I” tape. Many recordings are designed to record only on Type 1 tape. If you can’t find any switch or indicator on your recorder showing what type of tape it’s supposed to use, assume that Type I will work in all machines.

Many models can also use Type II cassettes, referred to as “chrome” or “high bias” tapes. Some recorders can recognize automatically whether an inserted tape is Type I or Type II. On other recorders you have to use a manual switch to set the recorder for proper operation with the tape type you’re using.

The highest quality cassette tape is called metal or Type IV (the short-lived Type III, or ferrichrome, was a blend of ferric and chrome oxides). Metal cassettes require much more bias current for proper recording, so using metal cassettes can reduce battery life in portable recorders by a third or more. But their sound quality, when used with a recorder that can drive them properly, is excellent.

Shell construction
A good shell provides environmental protection for the tape, keeps it packed smoothly, provides a low-friction path for the tape to move along during record and playback, and doesn’t warp in high temperature conditions. Shells made to closer tolerances for all these factors cost more money, but they’ll yield better sound quality and longer life for the cassette.

Many cassette shells are glued together or “welded” with ultrasonic vibrations. But the better shells are assembled with five screws, one at each corner and one in the middle. If an irreplaceable recording should ever suffer a jam or snap the tape, you’ll discover another advantage of screwed shells: you can disassemble the cassette, remove the tape, and splice or straighten it. Then you can reassemble the tape in the same cassette, or (if a damaged original shell was the problem) transplant the valuable tape to a “donor shell” from another cassette. In contrast, opening up a welded or glued shell requires prying and cracking which can further damage the tape.

For best results with cassettes, follow these guidelines:

Don’t use C90 or longer length cassettes. The tape in all cassettes up through C60’s (30 minutes per side, one hour total) is the standard thickness tape. The tape in C90’s and C120’s cassettes is thinner, and more vulnerable to damage, print-through and other problems.

If you reuse tapes for several recordings, bulk erase the cassettes to get rid of old recordings before making the new ones. This is particularly important if the cassette may get used in several different recorders: unless their heads are aligned exactly the same, one recorder may not be able to completely erase an existing recording made with another recorder.

If you intend to save a recording, break out the record inhibit tabs on the rear spine of the cassette. This will protect the cassette against accidental erasure.

Non-print equipment & services: Razor knife safety

This information is available as a powerpoint presentation from http://www.usd.edu/ehs/powerpoints/knifesafety.ppt

Always be sure that blades are properly seated in knives and that knives are properly closed and/or fastened together before use.

Always use sharp blades.

A dull blade requires more force and is more likely to slip than a sharp one. Change the blade whenever it starts to tear instead of cut.

Always keep your free hand (and other body parts) away from the line of the cut.

Always wear a cut resistant glove on your free hand while cutting with a razor knife.

Always pull – never push the knife.

The blade could break off – wedging in the material and cutting your arm severely.

Don’t bend or apply side loads to blades by using them to open cans, loosen screws or pry loose objects.

Blades are brittle and can snap easily.

Never leave a blade open.

Always retract the blade when not in use.

When making cut-outs on rolls always pull the knife down. Never push it a way from you.

When using a knife to cut through thick materials, be patient – make several passes, cutting a little deeper into the material with each pass.

Tips for changing blades

• Carefully remove the used blade from the knife.
• Always hold the blade at the non-sharp side.
• Discard the used blade in a safe place. Carefully wrap it in several layers of tape to cover sharp side and points.
• Make sure to reassemble the knife correctly. Make sure screw is tight.

• Close drawer s when not in use
• Open drawers slowly and carefully
• Avoid overloading filing cabinets, and distribute the weight of materials stored in cabinet to avoid tipping
• Furniture should be selected and maintained without sharp edges, points, or burrs

Good workstation set-up is based on individual needs.But there are some general principles that can be taken into account…Rule #1: If you are uncomfortable, seek assistance!

Considerations in setting up a computer work station

• How will the computer be used? How long?
• What kind of computer?
• What furniture will be used?
• What chair will be used?
• What can you see?
• Posture!
• Where will the computer be used?
• Take breaks
• Ergo. Gizmos – chair riser, keyboard brace

Good posture is essential to your health and safety!

• 3 natural curves
• Seated posture puts lots of strain on your body!
• Exaggerated curves are bad
• Stretch frequently
• Maintain or build strength

Easy reach

• Items to think about moving into the “easy reach” zone…
  o keyboard
  o mouse
  o telephone
  § could have a headset
  o calculator
• Avoid over stretching to reach items

Chairs

• Some adjustments to check out…
  o Seat height, depth, angle/tilt
  o Back height, adjustability and angle/tilt
  o Lumbar support
  o Arm rest height – is it appropriate?
  o Swivel
• Another pair of eyes. Does someone else think you’re sat safe and comfortable?

Your health &safety requires stretching/exercise “breaks”!

• Two types:
  o Aerobic exercise
  o Micro breaks
  § Micro breaks: short breaks to relax, restore, re-nourish, gently stretch

Material handling

• No lifting over 35 pounds on an occasional basis
  o Obtain assistance when necessary
• Avoid lifting objects that are too heavy for you!
• Plan the lift
• Stand with your feet apart, alongside the object to be lifted
• Use the “sit down” position, maintaining the natural arch of the spine
• Tuck your chin
• Get a good grip on the object
• Keep the object close
• Center the weight over your feet

Office equipment safeguarding

• Copiers (sorting trays, moving parts)
• Paper Cutter guarding to avoid contact with the cutting blade by the opposing hand (hand holding the blade)
• When cutters are not in use, cutter should be down and the blade secured
• Storage of letter openers and sharp tools (i.e. Exacto knives, scissors, etc.) should be appropriate to avoid tools rolling and falling off of desk surfaces
• Use sheaths for knives and razors
• Avoid twisting

11% of injuries = “struck by or between”

• Struck by or between what?
  o Doors
  o Office machines & equipment dropped on feet
  o Falling objects (from tables, cabinets & storage locations)
  o Copy machines
  o “Addressing” machines and fans
  o Paper cutters
