IRA6055 Lead edge dusting- Back ground

Will dust/ back ground for the first 5 or 6 pages.
Darkest on the lead edge and is lighter to the trailing edge.
Changed the transfer belt, cleaning blade.
Im thinking it might be the Transfer belt..?? Belt Bias..??
Any suggestions.

Thanx IW

Transfer belt..?? IRA6055..??

This is the name and part number
Iv'e seen these on Ricoh before and they would leave a back ground as well
I just changed the ETB cleaning blade and would solve the problem. Any suggestions.

Canon imageRUNNER ADVANCE 6055 Electrostatic Transfer Belt (ETB) FM4-0916-010

Any one out there had this problem...Thinking im going to change the transfer belt next.
Could it be a Bias problem, seen that on the old Ricoh Box's...... any suggestions ??
I like the transfer belt on higher speeds over Corona Wires ...way more reliable..

Thanx again IW

Bias issue.Good point.

From service bulletins Also can be:

-Defective Developing High Voltage Contact
-New Style Cleaning Blade?
-Drum Cleaning Assembly


Please post a sample.

There is a transfer roller in the ETB assembly, it goes bad sometimes
The bearings seize up too.
Sometimes you need to replace the whole assembly, modified ones have no springs to pinch when installing or removing

Thanks guys...This ones kinda got me baffled..(love this system thou, works way better than corona wires)
The old Ricohs were exactly the same, just replace the cleaning blade and you were good to go.
I think transfer roller controls the Bias ( could be wrong don't have a manual yet)
but will check the bearings and condition of the roller, cleaning unit and the Dev again.

Thanks
will post sample

Post a sample. Primary and pre-transfer corona wires been replaced? This is of course step 1...

How many copies are on the machine?

I would check the corona assemblies first.

I know you said you replaced the ETB assembly, but check to see if your ETB cleaning assembly is working..could be bad gears? Also check for toner build-up in registration assembly..usually this is visible though..

What does it look like if you run a solid black...does it go white on the lead edge? Try running a PG7 in service.

What is the paper profile on the machine? Is it possible that it is incorrect and changing the fusing characteristics too much?
