Upon detecting a fuser alarm, the CPU will stop printing (after printing the current page).
1.4.06 Main Motor (Drum Motor)
The main motor is controlled by the motor control LSI, on the main control board via the printer control
board. The motor used is a four-phase motor, driven by the motor driver integrated circuit located on the
printer control board.
1.4.07 LED Array
The printer control board provides serial transfer of print data (HDDT0) to the LED array. The signal
HDCLK provides data transfer timing. 1728 bits of data are shifted into the LED array registers. Then, the
signal HDLD loads this data into the latch circuits. This enables the individual LEDs.
1.4.08 DC Fan
The fan is controlled by the FAN ON-P signal from the main control board via the printer control board. In
order for the facsimiles printer to operate, the signal FAN SENSE-N must be active.
NOTE:
The fuser and the fan are not enabled when the cover is open. If the fan fails to run, the fuser will turn off
and the message PRINTER ALARM 3 will be displayed. Printing is disabled.
1.4.09 Registration Motor
The registration motor is driven clockwise for initial receive paper loading. It is driven counter-clockwise for
paper feeding. The motor is controlled by the motor control LSI on the main control board and is driven by
the motor driver integrated circuit on the printer control board.
