Maintaining Toner Cartridge

Toner cartridge storage

Toner cartridge life

expectancy

To get the most from the toner cartridge, keep the following guidelines in your mind.

• Do not remove the toner cartridge from its package until you are ready to use it.

• Do not refill toner cartridges. The printer warranty does not

cover damage caused by using a refilled cartridge.

• Store toner cartridges in the same environment as the printer.

• Do not remove a toner cartridge from the printer except to replace it, clean it or clear a paper jam. Replace the cartridge immediately.

• To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.

The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at 5 % coverage, a new toner cartridge lasts an average of 2,500 pages. (But, the toner cartridge supplied with the printer lasts an average of 1,000 pages.)

Recycling toner

Saving toner

After you install a new toner cartridge (see page 2.2), follow the instructions included in the toner cartridge box to recycle the old cartridge.

To save toner, press the Toner Save button on the printer control panel. The button will be lit. You can also enable the Toner Save Mode in your printer properties. Refer to “Using Toner Save Mode” on page 5.6. Selecting this option will extend the life of the toner cartridge and reduce your cost per page, but will reduce print quality.

MAINTAINING YOUR PRINTER

6.1

Maintaining Toner Cartridge

Redistributing Toner

When toner is low, faded or light areas may appear on a printed page. You may be able to temporarily improve print quality by redistributing the toner. The following procedures may allow you to finish the current print job before replacing the toner cartridge.

Grasp the front cover by both sides of the cover and pull it toward you to open.

Remove the toner cartridge from the printer.

CAUTIONS:

• Avoid reaching too far into the printer. The fusing area may be hot.

• To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.

MAINTAINING YOUR PRINTER

6.2

Gently shake the toner cartridge from side to side 5 or 6 times to redistribute the toner.

Note: If the toner gets on your

clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.

Reinsert the toner cartridge into the printer. Be sure that the toner cartridge snaps in its place.

close the cover.

MAINTAINING YOUR PRINTER

6.3

Cleaning the Printer

To maintain print quality, follow the cleaning procedures below every time the toner cartridge is replaced or whenever print quality problems occur. As much as possible, keep the printer free from dust and debris.

Notes:

• Do not use ammonia-based cleaners or volatile solvents such as thinner, on or around the printer. These can damage the printer.

• While cleaning the inside of the printer, be careful not to touch the transfer roller (located underneath the toner cartridge ). The oil from your hands on the roller can cause print quality problems.

Cleaning the Outside

Wipe the outside surface of the printer with a soft, clean, lintfree cloth. You can dampen the cloth slightly with water, but be careful not to let any water drip onto the printer or inside it.

Cleaning the Inside

Cleaning inside the printer

Note: To prevent

damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover it with a piece of paper, if necessary. Also, do not touch the black transfer roller inside the printer. By doing so, you can damage the printer.

During the printing process, paper, toner, and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems such as toner specks or smearing. Cleaning inside the printer will eliminate or reduce these problems.

Turn the printer off and unplug the power cord, then wait for

the printer to cool.

Open the front cover and remove the toner cartridge.

With a dry, lint-free cloth, wipe away any dust and spilled toner

from the toner cartridge area and the toner cartridge cavity.

MAINTAINING YOUR PRINTER

6.4

Cleaning the Printer

Reinsert the toner cartridge and close the cover.

Then, plug in the power cord, and turn the printer on.

Printing a cleaning sheet

Note: The cartridge

cleaning process takes some time. To stop the printing, turn the power off.

Printing a cleaning sheet cleans the drum inside the toner cartridge. Use this process if you are experiencing blurred, faded or smeared printouts. This process will produce a page with toner debris, which should be discarded.

Make sure the printer is turned on and in the Ready mode and

that there is paper loaded in the automatic input tray.

Press and hold down Demo on the control panel for about 10

seconds until all control panel lights remain lit, then release the button.

Your printer automatically picks up a sheet of paper from the

tray and prints out a cleaning sheet with the dust or toner particles on it.

Clearing Paper Jams

Occasionally, paper can become jammed during a print job. Some of the causes include:

• The paper tray is loaded improperly or overfilled.

• The paper tray has been pulled out during a print job.

• The top cover has been opened during a print job.

• Paper that does not meet paper specifications has been used. See “Paper Specifications” on page A.2.

• Paper that is outside of the supported size range has been used. See “Paper Specifications”.

If a paper jam occurs, the Paper and the Error lights remain lit on the control panel. Find and remove the jammed paper. If the location of the paper jam is not obvious, look inside the printer first.

Output Area

Note: Paper jams in this area may result in loose toner on the page. If you get any toner on your

clothes, wash them in cold water because hot water will set the toner into the fabric.

Pull the jammed paper carefully out of the output stacker.

PROBLEM SOLVING

7.6

If paper is jammed in the face-up output slot, carefully remove the paper as shown.

Open and close the front cover. Printing can be resumed.

Clearing Paper Jams
