First sample you sent blocked me for a moment. This second sample is different.
So all the internal printing is fine I suppose. And as you mentioned everything mechanical is OK in your scanning system.
Based on the first sample my first idea was the lamp regulator (but again you mentioned that the lamp is on) or the VIB as I mentioned in the first post.
Checking the second sample I'll go with VIB and ribbon cables leaving the CCD B140 5469 Harness - FFC SBU 15WICK/120mm
B140 5470 Harness - FFC SBU 40WICK/120mm.
Also check B065 5610 1st Scanner Harness (B064/B065) could be a bad connection (but I doubt it if your lamp it's on for 3 min)
Keep us updated
Here is the configuration for DIP SW 101

Controller Board
The controller board controls all devices for memory DIMMs, HDD, copying,
printing, scanning, etc. In order to add an option (printer, scanner, FireWire, wireless LAN, etc.), install the appropriate ROM DIMM on the controller board.
NOTE: 1) The Controller is on the front side of the swing out circuit board unit, with the IPU on the back side.
2) All Controller DIP SWs should be OFF during normal operation.
Turn OFF the DIP SW 101 - 6 and try again. IPU could cause similar problems with yours but if the internal prints are OK I doubt the board it's defective.
Check also the configuration of DIP SW on IPU
IPU (Image Processing Unit)
Processes images scanned by the CIS and SBU.
All IPU Board DIP switches should be set to OFF.
IPU Board DIP SW 102
No. Function On\OFF
1 DFU OFF
2 DFU OFF
3 DFU OFF
4 DFU OFF
DFU: Design, Factory Use only. Do not change these settings.
NOTE: The IPU is on the back side of the swing out circuit board unit.
Good luck!
Guicho, one of the following PCB's may have failed.
BCU ( I have had these fail)
SBU (I have replaced this maybe once)
IPU (I have never had one fail)
NEVER ASSUME ANYTHING
apreciated friend:
My problem now es (added to the black bands) SC543
The machine is unstable with Sc543
I changed middle thermistor, end thermistor, replaced BCU from another machine (May 10th)
I enter SP with 1106 temp. display =255
Off and on machine and is the same.
I cannot reset code 543.
I cannot print SMC report, SC History
???????????
Thanks for your help.
You may already know this, but sc543 is an 'A' level code. Enter service mode and then power off and on to reset. I am suprised a little that the BCU made no difference. This is a shot in the dark, but try a different hard drive, or a least format the one you have. Another possibility, update your firmware to the latest version. These are simple things to try, and they eliminate pontential causes.
Replace the entire fuser unit if you can.
NEVER ASSUME ANYTHING
I think the problem is interesting for all.
The machine is out of control.
I enter Sp when the fusing unit is cold (copying) (1106)(temp.display=255)(off machine)(on machine)
The result is Sc543 on display. Repeat the procedure several times. It´s the same.
I think I can´nt nothing more until change boards and I can format HDD or update firmware.
Note: I provide service to the machine for about 1 year and a half and never had a problem. (km. 2,000,000)
Thanks to all.
first problem is no display because of Fuse 111, i assume that you replace this with same ratings. i hope that the PSU was not affected by this open fuse. have you check the power supply? and i hope we have proper grounding...
fix the customer first then fix the machine... its simple and makes life more easy.
