Replace the print cartridge
1. Open the print-cartridge door, and remove the old print cartridge. See the recycling information
inside the print-cartridge box. To prevent damage to the print cartridge, minimize its exposure to
direct light by covering it with a sheet of paper.
2. Remove the new print cartridge from the packaging.
CAUTION: To prevent damage to the print cartridge, hold the print cartridge at each end.
3. Pull the tab until all the tape is removed from the cartridge. Put the tab in the print-cartridge box to
return for recycling.
4. Gently rock the toner cartridge from front to back to distribute the toner evenly inside the cartridge.
8 Chapter 2 Managing and maintenance ENWW
5. Insert the print cartridge in the device and close the print-cartridge door.
CAUTION: If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold
water. Hot water sets toner into the fabric.
NOTE: When toner is low, faded or light areas appear on the printed page. You might be able to
temporarily improve print quality by redistributing the toner. To redistribute the toner, remove the
cartridge from the device and gently rock it from front to back.

Information Pages drop-down list on the Services tab in Printer Preferences.

The Configuration page lists current settings and properties of the printer. It also contains a status log
report.
12 Chapter 2 Managing and maintenance ENWW
Clean the device
Clean the outside of the device with a clean, damp cloth when necessary.
CAUTION: Do not use ammonia-based cleaners on or around the device.
During the printing process, paper, toner, and dust particles can accumulate inside the device. Over
time, this buildup can cause print quality problems, such as toner specks or smearing, and paper jams.
To correct and prevent these types of problems, clean the print cartridge area and the device media
path.
Clean the print-cartridge area
You do not need to clean the print-cartridge area often. However, cleaning this area can improve the
quality of the printed sheets.
WARNING! Before cleaning the device, turn the device off by unplugging the power cord, and wait for
the device to cool.
1. Unplug the power cord from the device. Open the print-cartridge door, and remove the print
cartridge.
CAUTION: Do not touch the black-sponge transfer roller inside the device. Doing so can damage
the device.
CAUTION: To prevent damage, do not expose the print cartridge to light. Cover it with a piece
of paper.
ENWW Clean the device 13
2. With a dry, lint-free cloth, wipe any residue from the paper-path area and the print-cartridge cavity.
3. Replace the print cartridge, and close the print-cartridge door.
14 Chapter 2 Managing and maintenance ENWW
4. Plug the power cord into the device.
Clean the device paper path
If you are experiencing toner specks or dots on the printouts, clean the paper path. This process uses
a transparency to remove dust and toner from the paper path. Do not use bond or rough paper.
NOTE: For best results use a sheet of transparency. If you do not have any transparencies, you can
use copier-grade media (70 to 90 g/m
1. Make sure that the device is idle and the Ready light is on.
2. Load the media in the input tray.
ENWW Clean the device 15
2
(18 to 24 lb.)) that has a smooth surface.
3. Print a cleaning page. Access the printer Properties (or Printing Preferences in Windows 2000
and XP) then click on the Device Settings tab.
NOTE: The cleaning process takes approximately 2 minutes. The cleaning page will stop periodically
during the cleaning process. Do not turn the device off until the cleaning process has finished. You might
need to repeat the cleaning process several times to thoroughly clean the device.
16 Chapter 2 Managing and maintenance ENWW
Change the pickup roller
Normal use with good media causes wear. The use of poor media might require more frequent
replacement of the pickup roller.
If the device regularly mispicks (no media feeds through), you might need to change or clean the pickup
roller. See
CAUTION: Failure to complete this procedure might damage the device.
1. Open the print-cartridge door, and remove the old print cartridge. See the recycling information
Clean the pickup roller on page 20 to order a new pickup roller.
inside the print-cartridge box.
CAUTION: To prevent damage to the print cartridge, minimize its exposure to direct light. Cover
the print cartridge with a sheet of paper.
2. Find the pickup roller.
ENWW Change the pickup roller 17
3. Release the small tabs on each side of the pickup roller, and rotate the pickup roller toward the
front.
4. Gently pull the pickup roller up and out.
5. Position the new pickup roller in the slot. The circular and rectangular slots on each side prevents
you from installing the roller incorrectly.
6. Rotate the top of the new pickup roller away from you until both sides snap into place.
