Toshiba 281c

[purpleohm]

Hi, new technician here.

I was asked to fix a Toshiba 281c problem. When it prints/copies it makes a mechanical sound that's not supposed to be there. It's a high-frequency sound, like a spring squeking against metal. It's continous when it's making copy (goes up'n'down in freq though).

I tried changing fuser. No luck. Took out bridge. No luck. Then I took out the transferbelt unit. When I put it back and try to copy again the sound is gone.. for 5-15 seconds. I just have no idea where it comes from. The transferbelt unit looks allright. When I push the tension roller on the rear side it made the sound that we hear during copy. I put on some spray/oil of some kind, squeaking gone. Problem was, it was not the part making the sound when copying. Hehe..

Any ideas?

Will need to clean the TR1 rollers ends, and all other bushon are cleaned and lubricated. Make sure you put a tiny bit of grease between the c/e clip and the bushon (also make sure the clip is on the right way). If your new to 281c model and unsure I would get a manual as if you damage the belt its expensive. In the manual it shows you how to strip it down correctly.

You should try not to just spray oil into the machine, I am a fan of stripping it down, cleaning and lubricating (oil or grease) and rebuilding. Oil gets where it shouldnt be, for instance on your TR belt. Might damage it.

Just re-read this, you were poking around the TR unit while copying ('When I push the tension roller on the rear side it made the sound that we hear during copy')?

Hi, thanks for the info.

Yeah, I took out the unit and looked at it and pushed/pulled/rotated what I was able to on it. The tension roller resembled the sound that starts when startup-/copy-/printprocedure goes on. Seems it's just a general sound with mechanics or metal squeaking. Hehe, I'm new to all this. I'm a softwaredude trying to push my mind into mechanics and become a technician.

If you are unsure get a tech to get the noise resolved as if you damage the transfer belt it is expensive and will effect every (or most) copies/prints through the machine. Worst case could even cause your machine not to work at all due to a error code.

If you are going to have a go yourself I would get the manual for this machine (I dont give out manuals, others do. Manuals4you sells them). It has the info in for taking the TR unit apart. If you do decide to do this turn off and unplug the machine as there is a power switch at the front when taking the unit out.

A noise on a machine is the worst type of fault. I found a good fix on here for it, cant remember who it was. He got the customer a radio.......genius!
