Code
Error, Problem, Recovery
Problem
• Vtref (control reference voltage) could not be adjusted to within 0.2 V of Vt (TD
sensor output).
Recovery
• This is a TD sensor adjustment error (SC372 to SC375). Execute SP3801 again for
the PCU that returned the error. If this does not recover operation, check the next
four points.
• Film seal not removed from a new developer pack
• TD harness sensor disconnected, loose or defective
• TD sensor defective
• Harness between TD sensor and drawer disconnected, defective
Process Control Troubleshooting
Summary of Process Control SC Codes
This is a list of SC codes that may occur during process control. For more, please refer to the process control
tables on the following pages.
Pre-Processing Check
SC316 to SC319
Vpp is not within the normal range (Vpp: the AC current applied to the charge
roller to compensate for changes in the ambient temperature and humidity).
Insufficient charge causes white spotting and too much charge causes toner to
film on the surface of the drum. Vpp must be > 2.8 kV.
SC400
ID sensor could not be calibrated. An abnormal ID sensor condition is detected
when before calibration begins, Vsg < 0.5V or after calibration, Vsg cannot be
adjusted to 4.0±0.2V.
SC418
Correct current could not be supplied to the ID sensor.
SC436 to SC439
A problem is detected with a potential sensor during calibration.
Potential Control
SC410 to SC413
The development gamma is out of range (not between 0.3 and 6.0) for a color.
SC414 to SC417
Vk is out of range (not within ±150V) for a color. If the development potential is
less than Vk, toner is not applied to the drum.
