Routine Cleaning
The maintenance procedures you perform each time you replace
the imaging cartridge should keep your printer running at its best;
however, fine particles of paper dust and ordinary dust can collect
inside the printer. If you notice a decline in print quality, clean the
inside of the printer, the roller in the paper path, and the paper
feed roller as described below.
You should also clean the paper cassette and the printer case every
few months. These procedures are described later in this section.
After you clean the printer or replace the components, turn on the
printer so that it will print a start page, as described in Chapter 2.
If the start page is unsatisfactory, see Chapter 7 for
troubleshooting tips.
Replacing the ozone filter
Ozone is generated inside the printer by the high voltages used
during the printing process. The ozone filter located at the back of
the printer should be replaced every six months.
If you print many pages at a time, you may need to replace the
ozone filter more often.
Follow these steps to replace the ozone filter:
1. Make sure the printer is turned off.
