Supersedes Bulletin #7528 dated 8/3/11. Revised to reflect current firmware versions.

Based upon feedback from the dealer community, new firmware has been released that allows suppression oftoner warning messages. The end-of-life function and stop messages for fuser units, imaging and drum units,developer and developing units, and transfer belt units can be eliminated. Replacement of these units is basedupon usage instead of counter clicks. There are several benefits to turning these settings off:

Reduced customer downtime

Elimination of emergency calls forthese units

Elimination of emergency shipping charges for spare parts

PM is scheduled on the next customer-placed call

IMPORTANT: Because the end-of-life message is eliminated, print quality is not guaranteed if the lifecounter exceeds the specification value Consequently moni toring image quality depends upon both
