Canon C7580 III copy quality

[nkolee]

I have a C7580 III that is giving CQ issues leaving on test pattern 10 white streaks. Swapped ITB Belt Assembly and problem follows in another machine. Changed cleaning blade, still white streaks. Any ideas?

Did you change the transfer unit or transfer belt?

Changed (swapped) ITB belt assembly, cleaning blade. When swapped with a new assembly, problem did not follow. Have not changed ITB belt itself.

Problem is definitely coming from somewhere in ITB belt assembly.

Hi,

Clean the inner secondary transfer roller with a damp micro fibre cloth or replace it with a new one.
Please post back the outcome.

good luck.

Cleaned the inner roller, problem improved. Changed inner roller and also cleaned inside of belt, problem gone.

Many thanks!! 😁
