Do you run all of the required test after installing it???????

Could not find the code in the service manual

Depends on the error code?

Replace the transfer belt and roller and clean the sensor under neath the transfer belt

Sir/Mam, On the right side of the machine just below the scanner section (The part with the big glass) is a cover next to where you connect the Ethernet cable. Remove the cover, with the machine on use a small screw driver and gently depress the small black switch. The machine is going to go thru some screens when you see the screen with the copiers on it to the left on the screen in the middle you will see a "." when that is displayed press 3. The code will come back but now press the Utility/Counter button, you should see a button that says Maintenance Mode press that, see Trouble Reset press that and the machine will again will go thru warm up procedure, you will see the "." DO Nothing! The machine should go to "Ready to Copy" if the code comes back. Have a technician look at it DO NOT CONTINUE TO RESET the code is for the Hot Part called the FUSER. It can catch on fire! And that will ruin a perfectly good day!!!!

Has the transfer belt and transfer roller been replaced?

WARNING: DO NOT CONTINUE TO RESET the code is for the Hot Part called the FUSER. It can catch on fire! And that will ruin a perfectly good day!!!! Turn OFF the main power switch. 2. Turn main power switch ON while pressing the Utility/Counter key. 3. Touch [Trouble Reset]. 4. Check to make sure that [OK] is displayed and the it has been reset. 5. After turning off the main power switch, turn it on again more than 10 seconds after and check if the machine starts correctly.

why? what did you replace

document feeder paper draw (s) which one replace the rollers

Not something you should be dealing with, how why are you there?

Turn ON the power switch with the Clear/Stop key held down. or On the right side of the machine just below the scanner section (The part with the big glass) is a cover next to where you connect the Ethernet cable.

Description

Manual feed up/down abnormality. • Paper is not turned OFF (unblock) the bypass lift-up position sensor (PS26) even after the transport motor (M1) rotates for a given period of time after the position is switched from stand by position at lift-up plate to the feed position. • The bypass lift-up position sensor (PS26) is not turned ON (blocked) even after the transport motor (M1) rotates for a given period of time after the position is switched from stand by position at lift-up plate to the feed position.

Causes

• Transport motor (M1) • Bypass pick-up solenoid (SD1) • Bypass lift-up position sensor (PS26) • MFP board (MFPB)

Remedy

1. Check the connector between M1-MFPB CN8E for proper connection and correct as necessary. 2. Check the connector of M1 for proper drive coupling and correct as necessary. 3. Check the connector between PS26-relay CN19-MFPB CN18E for proper connection and correct as necessary. 4. Check the connector between SD1-relay CN21-relay CN19-MFPB CN18E for proper connection and correct as necessary. 5. PS26 I/O check, sensor check • Control signal: MFPB CN18E-13 (ON) • Location of electrical component: 22-J 6. SD1 operation check • Control signal: MFPB CN18E-10 (ON) • Location of electrical component: 22-J 7. M1 operation check • Control signal: MFPB CN8E-3 (REM), MFPB CN8E-6 (LOCK) • Location of electrical component: 2-C 8. Replace M1. 9. MFPB ICP3E conduction check 10. Replace MFPB.

Description

ATDC Sensor Failure - The scanning value of the ATDC Sensor is less than 7 % while the IU Motor is turning. - The scanning value of the ATDC Sensor is more than 19 % while the IU Motor is turning.

Remedy

1 Check the UN2 connector for proper connection and correct as necessary. 2 Remove the Developing Unit from the IU, and then replace UN2. 3 Run F8. 4 Change PWB-A. 5 Change PU1N.

Description

AOC abnormality. - AOC counter overflow

Causes

CCD board (CCDB) Exposure lamp (L1) L1 inverter (L1 INVVB) Scanner motor (M2) Overall control board (OACB)

Description

Offset adjustment error • Reading the black pixel output of each color from the data provided by the shading plate, the machine makes the offset adjustment for each color so that the average value of each color becomes within the specified range. However, after the machine attempts the offset adjustment three times in total (including two retries), the value is out of the specified range.

Remedy

1 Reboot the main body. 2 Clean the original glass. 3 Check the connector CN102, CN103 on MFPB for proper connection and correct as necessary. 4 Change scanner unit. 5 Change MFPB.

FS control board (FSCB) Shift roller motor (M2) Shift roller home sensor (PS18) The shift unit does not get to the shift position or the HP within a specified period of time.

The scanner home sensor is unable to detect the scanner located at its home position. 1. Correct or change the scanner drive (cable, pulley, gear, belt) if it is faulty. 2 Correct the scanner motor set screw if loose. 3 Adjust [Image Position Leading Edge] and [Feed Direction Adjustment]. 4 Check the PS201, M201, REYB/SCAN and IPB connector for proper connection and correct as necessary. 5 PS201 I/O check, sensor check. 6. Change REYB/SCAN. 7. Change IPB.
