Code: F2 44
Description: Image density sensor trouble (BLACK) (Transfer belt surface reflection abnormality)
Causes: "In the image density correction, the transfer belt surface is read by the image density sensor and the sensor gain is adjusted so that the output becomes a fixed value. However, the output of the specified range cannot be obtained even though the sensor gain is changed."
Remedy: Case 1 Trouble position/cause Image density sensor trouble Remedy (Check) "Check the image density sensor (dirt, output)(SIM44-2) / Check the image density sensor calibration plate. / Check the operation of the image density sensor calibration plate switching." (Repair) Clean or replace the image density sensor. / Clean or replace the image density sensor calibration plate. / Replace the image density sensor calibration plate switch solenoid. / Power Source-ON (After-work) Adjust ADJ M6 Note Case 2 Trouble position/cause "Transfer belt trouble (dirt, scratch)" Remedy (Check) "Toner dispersion from the transfer belt, the OPC drum unit, and the developing unit" (Repair) Clean or replace the transfer belt. / Replace the transfer belt cleaner. / Clean the OPC drum and the developing unit. / Power Source-ON (After-work) Note Case 3 Trouble position/cause PCU SUB PWB trouble Remedy (Check) Check the PCU SUM PWB image density sensor circuit. (Repair) PCU SUB PWB replacement / Power Source-ON
