Routine Cleaning; Replacing The Ozone Filter - Epson EPL-7000 User Manual

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.
Whenever you clean the printer or replace the components,
perform a test print as described in Chapter 2. If the test print 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. If you notice a peculiar smell when you
are printing, it is time to change the ozone filter.
Follow these steps to replace the ozone filter:
1. Make sure the printer is turned off.
