Signal Line Name Description
/HEAT ON AC power control signal of Heater Rod. Low: ON / High: OFF
MOTOR ON Control signal of MAIN MOTOR
MOTOR ALM Monitor signal of MAIN MOTOR
INTERLOCK AFT
Front or Rear Cover Open detection signal. Goes High when the Front or Rear Cover
is opened.
INTERLOCK BEF Front Cover Open detection signal. High when Front Cover is open.
FAN ALARM FUN SUB monitor signal. High when there is an error.
EXIT /INB Phase /B excitation signal of EXIT MOTOR.
EXIT /INA Phase /B excitation signal of EXIT MOTOR.
EXIT INB Phase /B excitation signal of EXIT MOTOR.
EXIT INA Phase /B excitation signal of EXIT MOTOR.
EXIT CUR A Current change signal for EXIT MOTOR.
EXIT CUR B Current change signal for EXIT MOTOR.
A and B Current output to each coil of EXIT MOTOR. Phase A, phase B
/A and /B Current output to each coil of EXIT MOTOR. Phase A, phase B
/PRFD Pre-feed signal. Works only when /RDY is Low
/CCLK Clock signal. Transmitted simultaneously with /STA or /CMD
/CMD
Command signal. Transmitted from the controller in synchronization with /CCLK
when /CBSY is Low.
/CPRDY
Ready signal of power to the controller. Turns Low upon completion of CPU
initialization after turning on of power to the controller. Turns High at occurrence of
any error in CPU
/START Printing start signal. Works only when /RDY is Low.
/CBSY
Command busy signal. Low during /CMD transmission.
(Except when /SBSY is Low or /PPRD is High)
/STA
Status signal. When /SBSY is Low, Status is transmitted in synchronization with
/CCLK.
/SBSY
Status busy signal. Low during /STA transmission from the printer.
(Except when /CBSY is Low or /PPRD is High)
/TOP
Vertical synchronizing signal of image data. Output periodically during operation of
ROS Motor.
/RDY Ready signal. Low during waiting for reception of /START.
/PPRDY
Ready signal of power to the printer. Turns Low upon completion of MCU CPU
initialization after turning on of power to the printer. Turns High when MCU has
detected an error.
/BD
Horizontal synchronizing signal of image data. Output periodically during operation
of ROS Motor.
/SLP Control signal for the LVPS. Low in power-saving mode.
/VDO1
Image data signal. Transmitted in synchronization with /TOP and /BD. High (White)
for any data other than effective data.
/VDO2
