Error C-6702

AGC abnormality.
AGC counter overflow

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


First off I'd try a trouble reset
1. Turn ON the main power switch (SW1).
2. With the Utility/Counter key pressed, turn ON the power switch (SW2).
3. Press [Trouble reset] to release a trouble with [OK] displayed.
4. Turn OFF and ON the power switch (SW2).

turn off the copier. Hold down the utility key and turn copier back on (still press utility key until Konicaminolta sign appear) trouble reset will come up. Press trouble reset. DONT TURN COPIER OFF Then go into techrep mode and do TCR When finished turn off. With any luck you should be able to leave client and have coffee . . .

here are some solutions...

Description

"Now Warming" displays if the machine is turned on with the right door open. When the door is then closed "Warming Up" stays on the screen. The fuser is
warm. If all

CAUSE: 2000 sheet LCT connections wires in connector are loose.
SOLUTION: Resolder connector wires or replace harness (p/n 4348 6801 02).


Description

C-6701 (C6701) or C-6702 (C6702) at power up. TheMFP scans to home position and the exposure lamp lights. If code is indicated during copy cycle, copies
may be all black.

Solution

PROBABLE CAUSES:
1.Failed Overall Control Board (OACB).
Check ICP3 on the OACB. If it is OPEN, checkfor shorts andreplace the Overall CB (p/n50GA -930 4M for bizhub 360/420/500 and p/n A0R5 H010 06 for
bizhub 361/421/501 ).
2.A communication issue between the CCD and OACB. Thisissue usually appears shortly after replacing or removing the OACB (Overall Control Board).
Please check the flat cable between the CCD and OACB. Make sure it is undamaged and connected properly. Replace the CCD cable (p/n 50GA 9050 0)if
reseating it has no effect on the service code.
3. During start up the CCD sensor is not initializing properly. Light from the exposure lamp is not being reflected by the white patch located under the platen
glass to the CCD sensor via the optics.
Make sure the optics is intact and positioned properly. Make sure the platen glass is also placed properly. The CCD also should be connected properly and
positioned properly. Be sure the cover for the CCD assembly is mounted correctly. Replace the CCD (p/n 50GA -626 1) if the optics and exposure system are
functioning properly.



Description

C-6702 (C6702) shortly after power up.

Solution

PROBABLE CAUSES:
1. The Overall Control Board/System Control Board has failed.
Replace the failed Overall Control Board/System Control Board (p/n 50GA-930 1H).
2. The CCD Board has failed.
Check ICP2 on the CCD board. If it is open, check for shorts and replace the CCDunit (p/n 50GA -626 1).
