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 set up 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 it. 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, nonearthed outlet; contact an electrician to have the outlet replaced. Do not use an adapter to defeat the earthing.

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

• If you are using an extension cable 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 13 amperes.

• The power outlet into which you plug your printer must remain accessible at all times.

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

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

OKIPAGE 8p/8w

Conventions

• 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. Always contact your local dealer.

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

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

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.

Toner Cartridge

Replacing the T oner Cartridge

Toner Cartridge Life

T oner 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 average, a toner cartridge will produce approximately 1500 sheets at 5% print density.

The first cartridge you place in your printer will produce between 500 and 700 sheets. This is normal, as the new image drum reservoir and developing roller must saturate with toner.

When to Replace the Toner Cartridge

Replace the toner cartridge when you see the TONER LOW message displayed on your screen. You can continue printing using the toner in the printer reservoir. However, you should replace the toner cartridge as soon as possible to maintain print quality and avoid possible damage to the imaging system.

Do not remove the new cartridge from its packaging.

1 Open the cover and remove the used toner cartridge.

Opening the cover exposes hot surfaces which are clearly labelled. Do NOT touch them.

2 Shake the new toner cartridge gently to distribute toner

evenly.

OKIPAGE 8p/8w

3 Unwrap the new cartridge. 4 Remove the tape.

6 Push the lock lever forward.

English

5 Insert the toner cartridge.

7 Close the printer cover.

Cleaning the LED Array

Clean the LED array…

• Whenever you install a new toner cartridge.

• If you see faded vertical areas or light printing down a page.

• If printing is fuzzy or blurred.

Wipe the LED array gently using a clean, lint–free cloth.

User’s Guide 11

Image drum Cartridge

Image Drum Cartridge Life

The life of an image drum depends on a number of factors, including temperature, humidity, the type of paper you use, and the number of pages per job.

The image drum cartridge should last about 10,000 pages for continuous printing, up to 8,000 pages at 3 pages per job (without power save).

When to Replace the Image Drum Cartridge

As the image drum approaches its end of life, CHANGE DRUM displays on your screen. At this point, be sur e you have a new drum on hand. Replace the old one as soon as print quality becomes faint or starts to deteriorate.

Replacing the Image Drum Cartridge

The image drum is a delicate unit and care should be taken not to damage it. It is therefore necessary to follow the guidelines listed below so the best print quality can be obtained from your printer.

• 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.

1 Open the cover and remove the used image drum cartridge.

Fonts

What is a Font?

Strictly speaking, a font refers to a set of printable characters in a particular typeface of a specific size (e.g. 12 point) and style (e.g. roman, bold or bold italic). In computer printing howev er, this term has been used in a wider context to refer to all sizes and styles of a particular typeface. In printers, fonts may be divided into two basic types: bitmap fonts and scalable (or outline) fonts.

Bitmap fonts are made up of a pattern of dots (at the printer resolution) to form the image of each printable character. These are of a fixed size, and scaling makes them look ragged.

Scalable fonts are stored as a set of mathematical curves. At print time the printer uses the stored curves to make up a bitmap of each character required, at the required size, and in the required style, at the full printer resolution. Such fonts are therefore said to be scalable, and do not appear ragged at enlarged sizes.

Using Fonts

The easiest way to select fonts is through your software program. Your software can send a printer command that consists of a set of codes, one for each of the font characteristics. If your software has the appropriate driver, you can specify the font you want, and it will send the necessary commands to the printer. For detailed information on how to select fonts in your software package, refer to your software documentation.

OKIPAGE 8p Fonts

These typefaces are resident in the OKIPAGE 8p:

• 35 MicroType scalable fonts

• 10 TrueType scalable font

• 1 Line Printer bitmap font

• OCR A/B

Print Quality Problems

Problem

Printed page is blank. Entire page prints faintly.

Printed page is fuzzy or blurred.

Page prints all black. Page has a grey background.

Vertical blac k lines on printed page.

Solution

The toner cartridge is missing or empty. Install a new toner cartridge. The toner cartridge is installed incorrectly. Re–install the toner cartridge . Make sure the tape is

removed from the bottom of the toner cartridge, the cartridge is seated correctly and the toner lock lever is pushed all the way forward.

T oner cartridge is empty . Replace the toner cartridge. Ensure that the image drum is located correctly and that the top cover is firmly closed. Use the printer control panel software to adjust the DARKNESS setting. LED array is dirty – clean the LED array. LED array is dislodged. Check alignment; contact service. Hardware problem. Contact service. Static electricity, gener ally from dry environments , causes toner to stick to bac kground. Change

paper to a smoother laser bond or use a humidifier. Is toner low? Replace toner cartridge. LED array is defective. Contact service.

To verify print quality problems, try printing several pages to check that the problem is persistent.

English

User’s Guide 19

Print Quality Problems contd.

Problem

V ertical white line or streaking on printed page.

Page has repetitive marks.

Smeared or blotched print.

Solution

T oner is low and does not distribute properly . Carefully remo ve image drum and shake side to side a few times to redistribute toner.

Damaged image drum causes repetitive marks due to surface nicks or scratches. Use the printer control panel software to generate a cleaning page; marks may be temporary.

Install a new image drum cartridge. Dirty rollers; toner dropped inside printer. Use the printer control panel software to generate a

cleaning page. Image drum problem; contact service.

Software Problems

It is essential to ensure that you have installed the correct Oki printer drivers. If printing from a DOS text box, your application should be set up for printing with an HP LaserJet™ II or compatible driver.

Problem

Printing is garbled. Printer's output is below rated speed.

Solution

Incorrect driver is installed or selected. Install or select Oki drivers pro vided with printer . Much of the printing delay will be caused by your application. Complex graphic images may take

longer to prepare for printing than simple text documents.

OKIPAGE 8p/8w

Hardware Problems

Problem

When you try to print nothing happens.

Printing is garbled.

Printer freezes, or an error message displays when computer is restarted.

Odours are given off by forms or adhesives passing through the hot fusing unit.

Printer is on but must “WARM UP” before a job is printed.

Solution

Configuration error. Chec k cable connection. If more than one printer is available, make sure your printer has been selected. Check printer status. If the printer light flashes slowly, the print job is progressing. If the light

flashes rapidly, use the control panel software to examine printer status. Incorrect cable configuration. Check cable configuration, type, continuity and length. Maximum

recommended length is 1·8m. See software problems. Starting the computer while the printer is on can cause a communications error. Turn the printer off

before restarting the computer. Odours are not emitted by the printer. Mak e sure the forms you use can withstand heating; provide

adequate ventilation. Pre–printed forms, transparencies and adhesive labels must be able to withstand 200°C (392°F) for 0·1 second.

Power Save mode is set to ON to conser ve energy. The fuser must heat up before printing the next job. To eliminate warm–up delay , use the printer control panel to change P ower Save setting.

English

User’s Guide 21

Hardware Problems contd.

Problem

Printed paper curls excessively.

Printer seems too hot.

Printed paper emerges wrinkled.

Solution

Heat from the toner fusing process removes moisture from the paper and may cause curling. If the curling is severe...

a Turn the paper over in the paper feeder. Put paper in feeder with print facing the back of the

printer, look on the package for an arro w or other indicator of the print side.

b A major cause of curl is improper storage. Store paper in a dry place, lying flat. Do not open the

paper package until you are ready to use the paper . c Try to protect your paper from excessive temperatures and rapid temperature changes. The toner fusing process in your printer generates a gignificant amount of heat, and the top cover

may feel quite warm. This is perfectly normal. If the top cover becomes too hot to touch, switch the printer off and call your dealer for advice.

Use the printer control panel to change the paper thickness setting to light.
