AC power-supply control signal for heater rod. Low: ON/High: OFF
Control signal for main motor (M1).
Monitor signal for main motor (M1).
Signal indicating that the rear cover is open. This signal goes High
when the front or rear cover is open.
Signal indicating that the front cover is open. This signal goes High
when the front cover is open.
Cooling fan motor (FM2) monitor signal. If a trouble occurs, this signal
goes High.
Excitation signal for exit motor. Phase /B.
Excitation signal for exit motor. Phase /A.
Excitation signal for exit motor. Phase B.
Excitation signal for exit motor. Phase A.
Current-switching signal for exit motor.
Current-switching signal for exit motor.
Current output to each winding of exit motor. Phases A and B.
Current output to each winding of exit motor. Phases A and B.
Prefeed signal. This is effective only when /RDY is Low.
Clock signal. This is sent out simultaneously with /STA or /CMD.
Command signal. When /CBSY is Low, it is sent out from the controller
in synchronism with /CCLK.
Ready signal for the controller power supply. This signal goes Low
when the controller power supply is ON and, at the same time, initial-
ization of the CPU is completed. When a trouble occurs with the CPU,
the signal goes High.
Print start signal. This is effective only when /RDY is Low.
Command busy signal. This goes Low when /CMD is sent out (except
when /SBSY is Low or /PPRDY is High).
Status signal. Status is sent in synchronism with /CCLK when /SBSY
is Low.
Status busy signal. This signal is Low when the printer is sending /STA
(except when /CBSY is Low or /CPRDY is High).
Vertical sync signal for image data. This is periodically sent out when
polygon motor is in operation.
Ready signal. This signal is Low in a standby state where reception of
/START is awaited.
Ready signal for the printer power supply. This goes Low when the
printer power supply is turned on and initialization of the CPU is com-
pleted. This signal goes High when the MCP detects an error.
Horizontal sync signal for image data. This is periodically sent out
when polygon motor is in operation.
Control signal for LVPS. This goes Low in power saving mode.
Image data signal. This is sent out in synchronism with /TOP and /BD.
This signal goes High (White) for other than effective data.
