Xerox 3400 Reference Guide

Maintenance and Cleaning 

Replacing the laser print cartridge

For replacement instructions, refer to the illustrated instructions included with the new 
laser print cartridge. You can also access the Phaser 3400 Laser Print Cartridge Installation 
instruction sheet on the Phaser 3400 printer’s CD-ROM.

Cleaning

Do not use ammonia-based sprays or volatile solvents such as thinner to clean 
the printer; they can damage the printer surface.

Cleaning the outside

Keep the covers and trays closed. Wipe the outside surfaces of the printer with a soft, 
clean, lint-free cloth. If needed, dampen the cloth slightly with water, but be careful not to 
let any water drip inside the printer.

Cleaning the inside

When paper jams occur, unfused toner on the paper can fall off the paper and build up 
inside the printer.

1.

Unplug the power cord and wait 10 to 15 minutes for the hot surfaces to cool.

2.

Open the top cover and remove the laser print cartridge. 

Do not expose the laser print cartridge to heat or direct sunlight.

3.

Use a soft cloth to wipe away any dust and spilled toner. If needed, dampen the cloth 
slightly with water but be careful not to let any water drip inside the printer.
