TASKalfa 300ci noisy

[kyove]

Hi Guys,

I have a problem with a TASKalfa 300ci. It works fine but makes a horrible sound. No paper jams and no errors on display/event log.
I make a video so you can hear the sound, download it here.

Sound is produced every time a print job was finished: if I print 10 pages, i hear sound at the 10th page, not every page.

Any ideas/suggestion?
Sound seems to come from the drive unit upper the main power board. I already try to change motor and developer motor.

Thank you in advance,
Kyove

How many clicks/counts on the machine.?
Sounds like a dry idler gear oscillating on the shaft???
Its in the final exit assy. Try running some output motor tests in service mode.

That is my vote also.

MFP has 107220 B/W and 7917 Color clicks for a total amount of 115137.
I've already tested with:
- U030 (motors)
- U032 (Clutches) with motor on
- U033 (Selenoids) with motor on
And i had no strange sound.

I have the noise when:
- I woke up the printer from standby
- After the printing job (video issue).

I think it's something in the exit section, il will make noise every page, not only at the last page.
I want to disassemble drive unit but unfortunately Service Manual do not talk about disassembly of drive units...

It's fairly unpleasant to dig into the main drive: 90 minutes minimum each way. I would make absolutely sure that's what you want to do, before you dig into the main drive.

If you cannot demonstrate your noise in U030, here are a few possibilities that will not appear in U030
-Guide B1 assembly not properly latched
-drum waste toner backup in the hopper assembly
-transfer waste toner backup

I have written up a step-by-step for removing the Saturn main drive. If you would like the PDF, please send a PM with destination email. =^..^=
