EN Chapter 3 Printer Tips and Maintenance 73
Cleaning the Printer
To maintain print quality, follow the cleaning procedures on the
following pages every time the toner cartridge is changed or
whenever print quality problems occur. As much as possible, keep the
printer free from dust and debris.
Clean the outside of the printer with a lightly water-dampened
cloth.
Clean the inside with a dry, lint-free cloth.
CAUTION Do not use ammonia-based cleaners on or around the printer. While
cleaning the printer, be careful not to touch the transfer roller (located
underneath the toner cartridge). Skin oils on the roller can cause print
quality problems.
Using the Printer Cleaning Processes
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. This printer has
two cleaning modes that can correct and prevent these types of
problems.
Note In order for the engine cleaning page to work properly, print the page
on copier-grade paper, not bond or rough paper.
Engine Cleaning
This process uses copier-grade paper from Tray 2 to remove dust and
toner from the paper path. Use this process if you are experiencing
toner specks or dots on printouts. This process will provide a blank
page which should be discarded. See “Starting the Cleaning Process”
on page 74.
Toner Cartridge Cleaning
This process cleans the drum inside the toner cartridge. Use this
process if you are experiencing blurred, faded or smeared printouts.
This process will take about 10 minutes. See “Starting the Cleaning
Process” on page 74.
