Sc 101 aficio 1060

**Guicho** · 05-10-2009

I need help for the followin problem:

1. fu111 fused
Action. Change the fuse
2. SC 541
Action. change thermisthor
3. the copies present black bands over the image.
Action. Change lamp harness, (same copies), change Lamp volt regulator (same copies), prove with another BCU (same copies)
Is it a problem with sbu o ipu?
I print the ipu patterns and they´re ok.

I thanks your replies.

sc101 could be as simple as dirty optics or white plate.
sc541 is indeed thermistors, usually a gentle clean and reset solves this

I execute procedure 4605 (scanner adjustment)
also I cleaned the white plate very well.
I fear the fail is in the mirror polygonal motor.
Fu111 does not protect the mpm?
Is´nt posible the fail resides en the digitalizer card behind the lens?
This fail is very strange for me.
Thanks.

If there's a problem in the polygon mirror motor the machine would give an SC320 call.

The machine is on.
Occur an Sc543 (PSU,BCU defective)
Note: the black bands are 4.5cm well defined or sometimes difused)
There are various problems at the same time.
Is it the Power Supply Unit PCB the first cause of all?

Thank you.

change the center thermistor and thermostat... be sure that you plug your machine at correct input voltage 220/110.... sc 101 veryfy all you touch harness perhaps you miss out one of them to put correctly... if you we have new flat harness and regulator for lamp....

Apreciated guys:

no SC´s, apparently nothing abnormal.
Continue appearing black bands when copying.
When use the printer all is fine
Reviewing the historial of the failure (firstly black bands)
Failure in the scanner (possibly lamp, (not credible to me))
what more can i do?
what more can i prove?

Thank you for your help

Try to replace B065 5195 VIB Board. I had the same problem with a 6000 and was the VIB board. It will be helpful to post a sample. In my case was dense lines just on copies.
