When prepare or while printing on a Taskalfa 3050ci there ist a squeak noise from the paper transport rolls, the machine has run 310.000 prints and has the 1.500 sheet finisher installed.

Any ideas which paper feed rolls should be controlled or replaced ? The prints are ok, just light scratches on the surface of the print.

Where can i get the most recent firmware for the Taskalfa ?

Thanks for your support, Tobias
