etc.

Troubleshooting

Timing of abnormal sound	Category	Frequency	How to check	Measure
Before printing	Hopper system operation sound	Always when cassette removed and inserted	Perform the following items from “Failure Verification” of service support mode. 3020102 C1 Liftup Motor/3020201 C1 FE Sensor 3030102 C2 Liftup Motor/3030201 C2 FE Sensor 3030104 C3 Liftup Motor/3030211 C3 FE Sensor 3030106 C4 Liftup Motor/3030221 C4 FE Sensor	Apply grease to gear shaft part on　cassette side. Replace lift motor Assy.
	Rear ASF system	Always temporarily when rear feeding	Perform the following items from “Failure Verification” of service support mode. 3020101 C1 ASF Motor 3020103 Rear ASF Solenoid	Replace the ASF Drive Assy. (Refer to ASF Drive Assy) Replace the Rear ASF Unit. (Refer to Rear ASF Unit)
	ASF motor related	(When printing first sheet)	Perform the following items from “Failure Verification” of service support mode. 3020101 C1 ASF Motor 3030101 C2 ASF Motor 3030103 C3 ASF Motor 3030105 C4 ASF Motor	Replace the ASF Drive Assy. (Refer to ASF Drive Assy)
	APG	Immediately before printing	Perform the following items from “Failure Verification” of service support mode. 30108 APG Operation Check	Check the state of the APG gear train gears (no broken teeth, etc.) Replace the APG Drive Assy. (Refer to ASF Drive Assy) *: Take care that there is no phase shift when removing and attaching the gear box.
	Retard Roller	Immediately before printing	Visually check the retard roller shape (no uneven wear, etc.).	Replace the retard roller. (Refer to Retard Roller) *: If the retard roller becomes unevenly worn, the friction coefficient will decrease and the roller will not rotate.
During printing	CR system	CR operation	Perform the following items from “Failure Verification” of service support mode. 3020105 CR Motor	When sound is output by moving the CR: Check whether there is a foreign object, and if there is, remove it. Clean the CR rib, shaft, and guide frame and then apply grease to them. When sound is always output when CR is reversed: Check whether there is a foreign object, and if there is, remove it. Check that the CR belt tension is appropriate. Check that fixing of the CR motor is appropriate.
	PF system	Always when printing	Perform the following items from “Failure Verification” of service support mode. 3020106 PF Motor	Abnormal sound from left side of main unit Insufficient grease on SMAP roller or EJ roller ground contact point: Apply grease. Check that the PF timing belt tension is appropriate. Check that a rattling sound is not output at the gear fixing E-ring. If there is rattling, change the orientation. Teeth knocking due to gear backlash: Apply grease to the idler gear shaft. Abnormal sound from right side of　main unit Abnormal sound from PF gear train gears: Check the state of the gears (whether or not tilted, etc.). If problem, reattach or replace them. When driving that is supposed to be off is connected: Check that movement of the Ink system assy is smooth. *: If necessary, replace the corresponding part.
	Nip Release Solenoid	Temporarily always only when feeding (single sound)	Perform the following items from “Failure Verification” of service support mode. 30110 NIP Solenoid/ Sensor Check	Check that the solenoid is fixed appropriately. If the Intermediate Release Solenoid does not operate, replace it. (Refer to Intermediate Release Solenoid)
	ASF motor related	(When print multiple sheets)	Perform the following items from “Failure Verification” of service support mode. 3020101 C1 ASF Motor 3030101 C2 ASF Motor 3030103 C3 ASF Motor 3030105 C4 ASF Motor	Replace the ASF Drive Assy. (Refer to ASF Drive Assy)
Between pages	Nip Release Solenoid	Temporarily always only when feeding (single sound)	Perform the following items from “Failure Verification” of service support mode. 30110 NIP Solenoid/ Sensor Check	Check that the solenoid is fixed appropriately. If the Intermediate Release Solenoid does not operate, replace it. (Refer to Intermediate Release Solenoid)
Between pages	ASF motor related	(When print multiple sheets)	Perform the following items from “Failure Verification” of service support mode. 3020101 C1 ASF Motor 3030101 C2 ASF Motor 3030103 C3 ASF Motor 3030105 C4 ASF Motor	Replace the ASF Drive Assy. (Refer to ASF Drive Assy)
When not printing	PF system	When CL suction	Execute the following item from the service support mode. 40102 CL1	Check the pump operation sound immediately after executing cleaning. If necessary, replace the Ink system assy. (Refer to Ink system assy)
When RIPS and front cover closed	IS system	Every time when cover closed	Perform the following items from “Failure Verification” of service support mode. 3020108 Ink Supply Pump 0 3020109 Ink Supply Pump 1	Replace the Rear ASF Unit. (Refer to Decompression Pump Unit)
