DC Controller Board Information
The DC controller board (DCCB) controls the printer. When the
PRINT signal is received from the video controller board, the DCCB
sends the print sequence command to the mechanical controller
board (MCB) which starts controlling the various loads.
The DC controller board retains important information in EEPROM
concerning drum life, oil out warnings, registration adjustments, and
so on. In addition, this board contains proprietary information and
should be replaced ONLY when directed by the appropriate service
check.
The DC controller board also provides:
•
Laser/Scanner control
•
Image stabilization control (environmental, toner quality,
photoconductor drum life)
•
Fuser temperature control
•
Power-OFF time measurement
•
Various detection functions
