Sharp MX-M465 toner on fuser entrance plate, flaking off

[DOSTECH]

I have a Sharp MX-M465N,
The toner started building up on the fuser entrance plate. right at very edge near lower fuser roller..
Toner will flake off and stick to back leading edge of misc copies. can just pic crusties off when comes out.
Running OEM toner/Dv. i just changed, put in new drum, drum housing, upper heat roller. web kit. / i did a Good PM, Maine is runnng clean, no toner spills.

It came back after 15k? toner build up. any ideas please?

thank-you

Low fuser temp? Can you take your finger and rub the toner off of the printed page?

no, cannot rub toner off page, but the toner flecks on the back of paper you can just pic off, it just started this, its crazy..

Are these 2 sided pages or is the toner build up at the fuser ramp putting the toner on the backside of the page?

single sided, the buildup is on the ramp, right near the lower fuser roller, mostly seem to be on underside of ramp.

I'm not familiar with this machine, but I've seen copiers where the drum sub-seal leaks and drops toner near the fuser ramp. Have you noticed little dark spots all over the front side of the page?

i know what you mean by sub seal bad, leaves toner spots,, copies are clean on front sides... machine is running clean...

Its just leaving toner crusties on bottom side lead edge,, only on the first 1/4 " of paper.. really wierd buildup..

Very interesting and I don't even work on these. I'd say you just saved the OP a lot of time and frustration. Good job.

You need to replace the transport roller above the fuser. They wear out. Causing the roller diameter to get smaller. in turn the roller spins faster pulling the paper tight to the fuser guide rubbing toner off the page. I have Replaced lots. NROLR1868FCZZ. Do not get the NROLR1868FCZ1 it is the wrong roller.

Thanks Everyone for such great posts, alot of info,

the only issue is all the bulletins are for the exit side of the fuser, my buildup is on the entrance side, the metal guide that can be moved up/down for wrinkles/jams. any ideas on the that side,,, thanks so much.
