Safety Instructions

Your Oki printer has been carefully designed to give you years of safe, reliable performance. As with all electrical equipment, however, there are a few basic precautions you should take to avoid hurting yourself or damaging the printer:

• Read the setup instructions in this handbook carefully. Be sure to save it for future reference.

• Read and follow all warning and instruction labels on the printer itself.

• Unplug the printer before you clean external panels. Use only a damp cloth; do not use liquid or aerosol cleaners.

• Place your printer on a firm, solid surface. If you put it on something unsteady, it may fall and be damaged; if you place it on a soft surface, such as a rug, sofa, or bed, the vents may become blocked, causing the printer to overheat.

• To protect your printer from overheating, make sure all openings on the printer are not blocked. Do not put the printer on or near a heat source, such as a radiator or heat register. Keep it out of direct sunlight. Allow enough room around the printer for adequate ventilation and easy access to the paper trays.

• Do not use your printer near water, or spill liquid of any kind into it.

• Be certain that your power source matches the rating listed on the back of the printer. If you are not sure, check with your dealer or with your local power company.

• Your printer has an earthed, 3-pin plug as a safety feature, and it will only fit into an earthed outlet. If you can not plug it in, chances are you have an older, non-earthed outlet; contact an electrician to have the outlet replaced. Do not use an adapter to defeat the earthing.

• To avoid damaging the power cord, do not put anything on it or place it where it will be walked on. If the cord becomes damaged or frayed, replace it immediately.

• If you are using an extension cord or power strip with the printer, make sure that the total of the amperes required by all the equipment on the extension is less than the extension’s rating. The total ratings of all equipment plugged into the outlet should not exceed 15 amperes.

• This printer must be installed near to a power outlet switch which shall remain easily accessible.

• It is recommended that the printer be switched off prior to opening or removing covers.

• Do not poke anything into the ventilation slots on the printer; you could get a shock or cause a fire.

Important Wiring Instructions

• Aside from the routine maintenance described in this handbook, do not try to service the printer yourself; opening the cover may expose you to shocks or other hazards.

• Lifting the top cover exposes hot surfaces. These are clearly labelled. Do NOT touch them.

• Do not make any adjustments other than those outlined in the handbook you may cause damage requiring extensive repair work.

If anything happens that indicates that your printer is not working properly or has been damaged, unplug it immediately and contact your dealer.

These are some of the things to look for:

• The power cable or plug is frayed or damaged.

• Liquid has been spilled into the printer, or it has been exposed to water.

• The printer has been dropped, or the cabinet is damaged.

• The printer does not function normally when you are following the operating instructions.

The wires in the power cable are coloured in accordance with the following code:

Green and Yellow — Earth

Blue — Neutral

Brown — Live

If the colours of the wires in the power cable of this printer do not correspond with the markings of the terminals of your plug, proceed as follows:

• Green and Yellow must be connected to the terminal

marked with the letter E (or the safety earth symbol) or the terminal coloured Green or Green & Yellow.

• Brown must be connected to the terminal marked with

the letter L or coloured Red.

• Blue must be connected to the terminal marked with the

letter N or coloured Blue or Black.

This printer must be earthed.

If you are in any doubt regarding the wiring, please contact a qualified electrician.

Toner Cartridge Life

Replacing Toner Cartridge

Toner cartridge life depends on the page density, the percentage of each page that is printed black. The higher the print density, the more toner is used. On the average, a toner cartridge will produce approximately 6000 sheets at 5% print density (5% is typical print density for text).

The first toner cartridge you place in your printer will produce between 2500 and 3500 sheets. This is normal, as the new image drum reservoir and developing roller system must saturate with toner.

When to Replace the Toner Cartridge

Replace the toner cartridge after control panel window. After will print 100 more sheets, then display stop printing. Printing will resume when a new toner cartridge is installed.

Image Drum Cartridge Life

Replacing the Drum Cartridge

The life of the image drum depends on a number of factors, including the operating temperature, humidity, the type of paper you use, and the number of pages per job. Each time you print or power on/off, the drum has to rotate to start up and to wind down. As a result, frequent one page print jobs will wear down your drum more quickly than multiple-page print jobs. The image drum cartridge should last approximately 19,000 pages at 3 pages per job when using simplex mode without Power Save. If you print mostly larger jobs it may last up to 30,000 pages.

When to Replace the Image Drum Cartridge

When the image drum reaches 90% of its life, the

message will display in the control panel

Use only the manufacturer’s standard image drum and toner cartridges specified for these printers.

Precautions:

The image drum is fragile. To avoid damage to the new drum, take these precautions while handling the new image drum cartridge:

• Do not touch the green drum surface.

• Do not set the cartridge down on anything that might scratch the surface of the drum.

• Do not expose the drum to direct sunlight and do not expose it to room light for more than 5 minutes. Leave it in the package until you are ready to install it into the printer.
