Having this loud buzzing sound coming from the back of my Phaser 6510 laser printer. Anyone know what the problem could be and have a solution? There's no jams or build-up. Just randomly started doing this during a print job and now it does it every time I print. The print quality is unusable as well. There is vertical track mark (2 tracks) and smudges all over. Help please!
I searched our online knowledge base and found two articles below that may help you with the noise and smudges.
If you're still having issues after trying these steps please consider calling our support department for additional assistance.
That sound is from transfer belt cleaner which is blocked with clogged toner, especially that I see a lot of residual toner into machine and on the transfer belt.
607K00936 is the part number for the transfer belt unit, and yes if you follow the instructions from the post that I linked before, you can replace it.
I've got the same problem and it was scuccessfully fixed after I cleaned the transer belt unit.
I've found a lot of stuff clogging the cleanning parts, especially the part connects to the waste cartridge.
Thanks a lot for your advice!
