Today i went to service 3 MP C3001, all the three machines had good print quality but one of the copier made some wistle sound when scanning by ADF.
i had a extra MP C3001 with me wich was tested fully and was 100%.
so i just removed the ADF and replaced it, half hour later when i'm back at office the customers call us again and says we have jam again??
any solutions ?
machine has a total counter of 300.000 .
