Maintaining the Printer

Replacing the Toner Module

Each toner module contains toner that can print up to
3,000 letter size prints. (The number of prints is
calculated based on an average image density
equivalent to a black-to-white ratio of 5% or lower.)
More or fewer will print depending on the image
density.
As the amount of toner still available for use in the
toner module is reduced, the print image gradually
becomes lighter. When that happens, remove the toner
module from the printer, shake it two to three times,
and reinstall it. If this still does not make the image
darker, replace the toner module with a new one,
following the procedure in the Setting Up the
Photoconductor Module and Toner Module section in
Chapter 2.

Replacing the Photoconductor Module

Each photoconductor module can print up to about
20,000 prints under the following conditions: NEC
recommended paper, continuous printing, and a black
to white ratio of 5%. The number of prints may be
fewer depending on print conditions, such as number
of prints you make at a time, the kind of paper, or the
print density.

07 Ch.6 Maintaining* 2
After the photoconductor module has turned out more
than 20,000 prints, the print image may become faint
and blurred. If this happens, replace the
photoconductor module with a new one, following the
procedure in the Setting Up the Photoconductor
Module and Toner Module section in Chapter 2.

Cleaning the Printer

Dust, dirt, and paper dust inside and outside the
printer aggravate printer performance and affect print
quality, making it necessary to clean the printer at
regular intervals.
Caution! Before starting the cleaning procedure,
be sure to turn the Power Switch OFF, and unplug
the power cord from the outlet.
Caution! The fuser unit inside the printer can
become very hot. Wait at least 10 minutes after the
printer has been shut down, and make sure that the
fuser unit has cooled down before touching the
interior.
