IBM 1800409-001A - Manual (Page 200)

A message on the control panel window, REPLACE BELT ,
indicates when it is time to change the OPC belt cartridge. This
cartridge should be replaced every 50,000 planes or 12 months,
whichever comes first. (A plane is a pass of the OPC belt for one
color, so a one-color page makes one pass, a two-color page makes
two passes, and so forth.) Changing the belt on a regular basis helps
prevent the print quality from deteriorating.
NOTE: You may want to clean the paper guide and the register
and paper exit rollers at this time also. They should be
cleaned every 20,000 copies or 12 months, whichever
comes first. The procedures for cleaning these parts are
given later in this chapter.
Illustrations for many of the steps described in this section on
replacing the OPC belt cartridge are in chapter 2, “Initial Printer
Setup.”
To replace the OPC cartridge, use the following procedure:
1. Open the manual feed tray.
2. Lift the handle of the old OPC belt cartridge up to unlock it.
3. Pull the cartridge straight out of the printer, and discard it.
CAUTION: The OPC belt is extremely sensitive to bright lights
and direct sunlight. Do not remove the new cartridge from its
protective bag until you are ready to install it. Limit exposure to
800 lux (the average fluorescent lighting in an office) of light to
under 2 minutes. If exposure exceeds this, put the belt in a dark
place to recover; depending on exposure, recovery may take up to
2 hours.
Also, handle the belt cartridge carefully by either the two green
side-handles or by the green end-handle. The belt is extremely
