Description
/HEAT ON
AC power-supply control signal for Heater Rod. Low: ON/High: OFF
MOTOR ON
Control signal for MAIN MOTOR 45.
MOTOR ALM
Monitor signal for MAIN MOTOR 45.
INTERLOCK AFT
Signal indicating that the rear cover is open. This signal goes High when the front or
rear cover is open.
INTERLOCK BEF
Signal indicating that the front cover is open. This signal goes High when the front
cover is open.
FAN ALARM
FUN SUB monitor signal. If a trouble occurs, this signal goes High.
EXIT /INB
Excitation signal for EXIT MOTOR. Phase /B.
EXIT /INA
Excitation signal for EXIT MOTOR. Phase /A.
EXIT INB
Excitation signal for EXIT MOTOR. Phase B.
EXIT INA
Excitation signal for EXIT MOTOR. Phase A.
EXIT CUR A
Current-switching signal for EXIT MOTOR.
/MOT SPEED LOW
Half-speed signal for MAIN MOTOR.
A and B
Current output to each winding of EXIT MOTOR. Phases A and B.
/A and /B
Current output to each winding of EXIT MOTOR. Phases A and B.
/PRFD
Prefeed signal. This is effective only when /RDY is Low.
/CCLK
Clock signal. This is sent out simultaneously with /STA or /CMD.
/CMD
Command signal. When /CBSY is Low, it is sent out from the controller in synchro-
nism with /CCLK.
/CPRDY
Ready signal for the controller power supply. This signal goes Low when the control-
ler power supply is ON and, at the same time, initialization of the CPU is completed.
When a trouble occurs with the CPU, the signal goes High.
/START
Print start signal. This is effective only when /RDY is Low.
/CBSY
Command busy signal. This goes Low when /CMD is sent out (except when /SBSY
is Low or /PPRDY is High).
/STA
Status signal. Status is sent in synchronism with /CCLK when /SBSY is Low.
/SBSY
Status busy signal. This signal is Low when the printer is sending /STA (except when
/CBSY is Low or /CPRDY is High).
/TOP
Vertical sync signal for image data. This is periodically sent out when ROS MOTOR
is in operation.
/RDY
Ready signal. This signal is Low in a standby state where reception of / START is
awaited.
/PPRDY
Ready signal for the printer power supply. This goes Low when the printer power
supply is turned on and initialization of the CPU is completed. This signal goes High
when the MCP detects an error.
/BD
Horizontal sync signal for image data. This is periodically sent out when ROS
MOTOR is in operation.
/SLP
Control signal for LVPS. This goes Low in power saving mode.
/VDO1
Image data signal. This is sent out in synchronism with /TOP and /BD. This signal
goes High (White) for other than effective data.
/VDO2
