C253 loud banging noise

[fishleg]

Had this happen to us a few times impossible to fix at a customers. 3 hours taking stuff out and got no where for us a seized IU caused a backup of toner in the toner hopper. Used an air compressor in work shop and blasted the hell out of it seemed impossible to get the VAC deep enough for us. Good luck...

Hi Tam

I have exactly the same problem with Magenta supply hopper backing up & making that noise, I was just wondering if you sorted it out on your return visit?

Thanks

Colin

Hi Colin,

No I didn't fix it on my return visit. The noise was exactly the same so we pulled it out and put a loaner in.
Previously I had diagnosed it as the split pin missing from the M IU, which of course was the cause of all the trouble. But the toner chute was backed up again, but nothing to do with the pin being missing from the M IU.
It was tiny, and I mean really small bits of compacted toner in the chute and horizontal toner conveyance coil for Magenta.
I would suggest doing everything possible to fashion a tool to attach to a compressor or vacuum then either blow and/or suck from the top and bottom of the chute. Bang it, tap it, just do all you can to ensure it is toner free.

Have had 2 more do this since my original post. Both of these were the same, compacted toner.

Good luck, sorry for the late response.

Regards

Tam

We had another machine do this... Now I don't know if its just random but turning the dev gears on the IU it felt tight compared to the rest.

That IU had been chipped so my theory... Reset chip screws TCR causing machine to overtone which eventually backs up.

Hi you have yourself one massive job there suggest you uplift this machine and take to your workshop becuase you going to have to strip the entire rear and front section out to get the toner recycling unit out of the machine two things to look for once you got it is the recycing auger clogged or snapped strip out clean or replace, the two gears on the end that links up to drive section are either of them stripped or both have had this before basically comes from waste toner box not being emptied or changed regularly front door is open and closed to fool machine you have mission on hands work carefully you want to reassemble this machine and get it to work properly again good luck buddy
