Product: Phaser 7760

Operational Groups: All

PROBLEM:

The Phaser 7760 no longer recognizes the Imaging Units as the correct

ones for the product after the Engine NVRAM board (MCU-MF NVM

PWB, P/N 160K76652) is changed.

If the Store Engine NVRAM function is not performed before replacing

the Engine NVRAM Board, the correct parameter for recognizing Phaser

7760 Imaging Units will be lost.

CAUSE:

The Engine NVRAM Board is a common part used in many different

products. In order to function correctly in a particular product, a

number of parameters must be programmed. One of these parameters is

the unique code that recognizes the Imaging Units specifically

designated for that product. These codes are programmed to the Engine

NVRAM Board during production. In order to be written correctly to a

replacement NVRAM board, the Store Engine NVRAM and Resetting

NVRAM procedures within diagnostics should be followed.

SOLUTION:

If the Phaser 7760 Image Unit are no longer correctly recognized after

replacing the Engine NVRAM Board and the Resetting NVRAM

procedure within diagnostics does not restore this functionality;

1. Send the Image Unit ID postscript snippet to the printer.

a. This snippet can be downloaded from:
