SC 322, SC 326, SC 990 and /or Open Door Indication

[Symptom]

SC 990, SC 322, SC 326, and /or Open Door Indication

SP7-403 Error Log for SC 990 Software Performance Error Details

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 1^st Laser Synchronization error and/or SC 326 2^nd laser Synchronization Error

Open Cover Indication without indicating which cover is open, opening and closing of individual covers gives proper indications.

[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)

1. Clean and vacuum the PCU.
2. Clean the Toner Shield Glass, Charge Roller and ID Sensor.
3. Check Service history for Drum Life, if over 150,000 replace Drum (Part Number A230 9510)
4. Reset SP 2103 -1 thru 4 to defaults.(LD Power Adjustments)
5. Reset SP 2001-1 to its default. (Charge Roller Bias Adjustment)
6. Execute SP 3001- 2 (ID Sensor Initial Setting)

help-me

When you give a little bit more information than just "help me", chances are greater that you can solve your problem.

Eric1968 right, its much better to give information on the problem than help me. anyway replace the door switches and/or check the actuator that pushes the door switches if they had a good contact.

also check switches above fuser

Re: door open in aficio 2045e

if ribbone cable is unreachable sc690 is already generated and give you open door signal .... yo wellcome

Re: door open in aficio 2045e

WOW...a lot of responses to such a dumbass way to ask a question.!!!
And yes...it'll be the door switches.

can try on the laser data cable connection
