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;
