Xerox 2121 用户指南

To maintain the best operating conditions for your machine, ensure that you:

• Never leave the cover open unless required.

• Do not attempt to oil the machine.

• Always close the cover carefully and avoid vibrations.

• Do not open the cover while printing.

• Never try to dismantle the machine.

• Do not use paper that has been kept in the paper tray for a long time.

• Read the safety rules in the Safety & Environment chapter at the end of this 

booklet.

There are 2 customer replaceable units in the machine:

• Toner Cartridge: - 006R01297

• Drum Cartridge - 013R00628

The standard toner cartridge can produce up to 6000 pages (when printing on Letter 
paper with a 5% area coverage) or 10000 pages ITU No. 1 in normal mode.

The initial toner cartridge can produce up to 2000 pages (when printing on Letter paper 
with a 5% area coverage).

The service life of the toner cartridge mainly depends on the type of printed document 
and the average number of pages per print operation.
