B-2 Appendix B — Firmware Upgrade
CAUTIONS (Continued)
!
Whenever you remove the drum cartridge, place it in its original
container or other protective covering and store it in a dark location.
Prolonged exposure to strong light deteriorates the green organic
photoconductor coating on the drum.
!
Never use the fuser exit cover on the back of the printer as a handhold
for lifting the printer. Lift the printer only along the sides of the printer.
The printer contains two types of firmware 1 :
•
The raster image processor (RIP) firmware controls the processing of
data from the computer to the print media. The RIP firmware is
located on a mini-PCB which is inserted into a connector on the RIP
controller PCB.
•
The engine controller (EC) firmware controls the mechanics of the
printer. The EC firmware is located on a single ROM IC which is
inserted into an IC socket on the EC PCB.
To remove or install any firmware first the RIP controller PCB must be
removed as explained in RIP Controller PCB Replacement in Appendix A.
1 Firmware is the name used to describe software residing on one or more computer memory chips called read only memory
(ROM) integrated circuits (ICs).
