sc322 appeared only in print but not appeared in copying
recently i cleaned toner spilled near the developer and remove opc and developer and clean the glass of laser
please guide me about troubleshooting
thanks a lot

Re: sc322 appeared only in print in 2035

i opened the 6 Laser unit connectors cables and reinsert them into it and clean the bottom of LD board (toner spilled) with brush and switch on the machine , this time sc322 appeared on first copy
please guide me troubleshooting

Re: sc322 appeared only in print in 2035

Unfortunately the laser unit is now broken. You'll need to replace the complete unit.

Re: sc322 appeared only in print in 2035

I would try reseating all the connectors, especially the flat cable. After that run laser pitch adjustment SP2109. The full procedure is in the manual. If no joy after that, TM is right. Time for a new LD unit.

Use a cotton stick to clean inside the Laser Unit, mirrors, synchro board and Laser diode unit.
Give it a chance once again...

Try change the door switches above the fuser

Re: sc322 appeared only in print in 2035

try this, clear "engine" memory. initialize laser beam pitch 400 and 600. If it still don't work, replacement is a must. good luck

[Symptom] SC 990, SC 322, SC 326, and /or Open Door Indication SP7-403 Error Log for SC 990 Software Performance Error Details shows eng_procon.c LD Power Adjustment SP 2-103 - 1 and 2 read near maximum value of 62, SP 2-103 - 3 and 4 read near maximum value of 32 SC 322 1st Laser Synchronization error and/or SC 326 2nd laser Synchronization Error Open Cover Indication without indicating which cover is open, opening and closing of individual covers gives proper indications.
	Answer
	[Cause] Dirty contacts on Upper Right Cover Safety Switches. Toner gets inside the Upper Right Cover Safety Switches, which can lead to lower DC voltage being applied to the Laser Diode. Which leads to: SC 990 eng_procon.c (when a normal Grayscale pattern was not detected 15 times consecutively during ID Sensor Grayscale pattern check) check with SP 7403 Service Code History look for Detail in history of SC 990. LD Power not being strong enough to be read by Laser Synchronizing Detector causing a SC 322 or 326 depending upon timing. 5vdc not being fully applied to connector 403 pin 3 on the Laser Diode PCB causing an Open Cover Indication, or 24vdc not being applied fully to connector 107 pin 2 on the PSU PCB causing an Open Cover Indication. Circuit Explanation: 5vdc (VCCD)is output from connector 403 pin1 of the Laser Diode PCB where it travels through 2 of the Upper Right Cover switches than through 2 of the Front Cover Safety switches before being applied to connector 403 pin 3 of the Laser Diode PCB where it is now used to power the Laser Diode. Lower voltage on pin 3 leads to lower laser diode output which causes the machine to raise LD Power (SP 2-103) when maximum values are reached, laser diode output can not be increased further which can lead to SC 322, SC 326 and/ or SC 990 eng_procon .c. If the voltage drops too low an open door indication is sent to the BICU PCB but a signal is not sent to the IOB PCB which tells the machine which door is open. Note: An older Drum more than 150,000 copies can also lead to SC 990 by causing incorrect ID Sensor readings [Resolution] 1. Clean the internal contacts or replace Right Door Safety Switches (2 of Part Number 1204 2521 and 1 of Part Number 1204 2529) Clean and vacuum the PCU. Clean the Toner Shield Glass, Charge Roller and ID Sensor. Check Service history for Drum Life, if over 150,000 replace Drum (Part Number A230 9510) Reset SP 2103 -1 thru 4 to defaults.(LD Power Adjustments) Reset SP 2001-1 to its default. (Charge Roller Bias Adjustment) Execute SP 3001- 2 (ID Sensor Initial Setting)

changes was done but problem still exist

i released all 6 cables and clean the laser unit but i saw that the Shield Glass is not go out because metal holder of it (front) is not attached to it.
additionally i change the 2103-1(LD1) and 2103-1(LD2 power) to 64 and i remembered the old value please guide me about restoring to previous setting 2103
thanks a lot

Re: sc322 appeared only in print in 2035

Hang on, you mean you're running this machine with no laser slit glass in it?

[xtreme-jodi]

Re: sc322 appeared only in print in 2035

Try change the door switches above the fuser

+1 i encounter that 5 times and i'd found that one of the micro switch is defective

please explain more about micro switch or note part number of it

no , only the holder separated from glass inserted in front of Laser unit and can not exit glass

Re: sc322 appeared only in print in 2035

The metal protector is not attached to the glass. Sounds like the end of the glass is broken off. Use a pencil eraser to get it out. Also, these guys are right about the front cover safety switches. They get caked with toner and cause this problem. See the attached file.
