[Mina Banoub]

Hi everybody
I am facing a situation with a canon machine model iradv6555 that poops up with error code E302 -0001 when trying to send a compact PDF document or any other color format to a shared folder but it goes fine when I send it B&W. Machine installed few months ago and its counter is almost 50000 and placed in a clean place (no dust ) , all optical parts are clean.
