Subject:

Abnormal buzzing sound occurring from Intermediate Transfer Belt Assembly

Detail :

Abnormal buzzing sound occurs from the Intermediate Transfer Belt Assembly (FM2-0407).

<Cause>

When the edge of the Internal Scraper (FL2-0398) of the Intermediate Transfer Belt assembly is subject to

adhesion of rubber residues of the rubber rollers, such as the Secondary Transfer Roller, there is an increase in

the sliding frictional resistance between the Internal Scraper and the Transfer Belt, causing the scraper holder

to vibrate. When the vibrating scraper holder comes into contact with the frame, a rustle occurs, leading to

abnormal buzzing sound.
