prescribed time. (The BCU generates the FGATE
signal and sends it to the LD unit when the
registration sensor switches on.) • BCU, Controller board
harness loose or broken
SC 231 : FGATE OFF error
The FGATE signal did not go off within the
prescribed time. (The BCU generates the FGATE
signal and sends it to the LD unit when the
registration sensor switches on.)
SC 240 : LD error
The IPU detected a problem
at the LD unit.
SC302 : Charge level output error
The PWM output level was detected higher
than 50% after 10 consecutive samplings.
SC 350 :ID sensor calibration – Error 1
One of the following conditions occurred when the ID sensor pattern was calibrated
during printing:

Vsg = 0V
SC 351 : ID sensor calibration – Error 2
The following conditions occurred simultaneously when the ID sensor pattern was
calibrated during printing:
Vsg = 5V
PWM = 0 (LED current drop)
High voltage power supply board (power pack) defective
353 B ID sensor LED current error
Error occurred during automatic
adjustment of Vsg:
ID sensor dirty or defective
SC 354 : ID sensor adjustment timeout error
Error occurred during automatic
adjustment of Vsg. Vsg could not
be adjusted to 4.0V ±0.2V
within the prescribed time.
SC 355 : ID sensor error
For more details about the cause
of the problem, please refer to
SC350 to SC 354 above.
• ID sensor dirty or defective
• ID sensor harness disconnected, or connector damaged
• BCU defective
• High voltage power supply board (power pack) defective
SC 389 : TD sensor error 1
TD sensor output was less than 0.5V, or more than 0.5V 10 times in succession. If the fax
unit is installed, this SC is issued immediately. If the fax unit is not installed, this SC is issued
after the prescribed number of copies has printed.
SC 390 : TD sensor error 2
The TD sensor outputs less than 0.5V or more than 4.0V 10 times consecutively during
copying.
Note: If the fax option is installed, this SC is issued immediately.
If the fax option is not installed, this SC is issued after the prescribed number of pages is
copied.
SC 391 : Development bias leak
A development bias leak signal is
detected.
SC 392 : TD sensor initial setting error
Initialization of the new PCU unit
failed (the drum and development
roller did not start rotating).
SC 401 : Transfer roller leak error 1
A transfer roller current leak signal wad detected. (The current feedback signal for the
transfer roller was not detected within the correct time.)
SC 402 : Transfer roller leak error 2
A transfer roller current leak signal is detected.
The current feedback signal for the transfer
roller is not detected within the correct time.
SC 411 : Separation bias leak error
A separation bias leak signal was detected.

The temperature of the hot roller remained below 0oC for
5 sec at the center of the hot roller.
SC542 : Fusing temperature warm-up error (center)
The fusing temperature did not reach the standby temperature within 20 sec. at the
center of the hot roller after the main switch turned on.
SC 543 : Fusing overheat error 1 (center)
