Broken Fuser gears 2075- MP 8000

[Codex]

Hy
Did someone had problems with broken fuser gears on this series? I experienced a lot of broken gears during the year...i know ricoh changed the material , earlier gears was yellow...now they are grey...but the problem is the same....they break very easily. Yesterday i cleaned a machine...i made a print of the counter before i start to disassemble everything. ..then...after cleaning i made another counter to have a kind of "then and now"..and the machine jams in the fuser....gear broken...

I haven't had a large issue but it has happened a few times. Even on newer machines like the 6002. They always seem to break into two equal pieces like that.

i have been told that the gear breaks due to flat spots on the press roller, it causes uneven pressure on that gear. i have found very few press rollers with flat spots when i did have to replace the gear. so i'm no sure how true that its. but its something to look at.

Usually caused from flat spot in pressure roller, replace press roller with bearings, upper bearings too. Adjust web motor settings per bulletin 15, enable auto shut off if disabled so machine doesn't stay on over weekends.

What kind of settings in bulletin 15?

I use to have one in my Van kit.
Since they changed Vendor(?) material(?) it happens.

Something to keep in mind by changing those web settings is that the machine will consume the fusing web at a higher rate.

As a side note, I'd ensure the fuser rollers were nice and lubed and check the bearings for seizing. These things get pretty nasty pretty quick. I go out to one 7502 a week at least for thermistor sensing errors due to toner build up on the thermistor.

We have about the same. There is a TSB for that series a for adjusting some SP settings that is supposed to help. I'm not convinced at the moment though.

I experienced sc 542 and 552 due to toner build up on the thermistors.......since we have the type 9002...

Seems to me sometimes TSB's are there to only seem like they've fixed a problem without actually doing anything. Take the TSB for noise coming from the fuser for the C2551, for instance...

Plain and simple....shittily designed gear!...even though they have the angled tooth helical design, the gear body doesn't have nearly enough "meat" to it to keep it together!...and like others mention, they almost break exactly in half! There was only one that I remember failing that it either had just a smaller chunk break out of it or it cracked on one side and was getting ready to split on the opposite side! As long as Ricoh has been around you'd think they'd do a better job with their materials enginnering!...oh well, I guess not!
