MP401 Somethings fishy here.

Re: MP401 Somethings fishy here.

Ok glad it is not just me. Do you have a link or something to this study by Ricoh? Also how do add a filter to the ventilation system on these units?

Re: MP401 Somethings fishy here.

Ricoh came out and said that it was the result of developer working through the rear bushings on the mixer shafts and to replace the development unit

I've had this issue with 5002 and it's predecessors. Machine didn't even make it to 160k. God I hate those machines so much.

What did you use as the filter mesh?

Also here is the picture of the messed up drum I promised. They just called again today for lines. Tally ho boys.

Re: MP401 Somethings fishy here.

When I went yesterday the drum in the machine was damaged as it has been before, just in a different location closer to the edge of the drum. I went back this morning and called Ricoh tech line and they literally had nothing for me other than to tear the machine down and look for a cause. Their other suggestion was to replace the transfer roller along with a new drum.

My plan is to do the transer, drum, a new toner cartridge and to add a filter to the PCDU fan intake as well.

I plan to. Just waiting for parts.

Re: MP401 Somethings fishy here.

I have some experience with adding ventilation to Canon and Sharp machines, im sure i could explain the principle and you could apply it to a Ricoh.

Big exit wounds. What caliber?

Re: MP401 Somethings fishy here.

I just thought of this: Quite a while back we had a mpc300 that was taking out drums, and I could find no cause for it after hours of troubleshooting. I finally grasped at a straw and filtered through the toner running through he machine and found super hard chunks of contaminant in the K toner (the chunks didn't look like toner, but tiny pieces of plastic. Cleaned the old toner out and cycled new toner from a different lot# and the issue was resolved.

I plan on putting a new toner cartridge in with the drum. This machine feeds toner directly to the drum cartridge from the toner unit. None remains inside the machine.

Re: MP401 Somethings fishy here.

Speaking of grasping at straws.
I notice "toner collection coil breakage" is mentioned in the June firmware update.
Could the collection coil be contacting the drum?
Or waste toner packing up at one end of the drum?
We recently sold a bunch of SP3610 and SP4510 to one customer so I'm curious to see if they start failing & what the solution is for the MP401.

I ripped the drum cartridge from the previous failure apart and the toner collection coil was in one piece. I'm pretty sure the solution will be throwing it in the gorram river.

I have to agree with Jake, look for something metal.

Re: MP401 Somethings fishy here.

I go for the clounged toner:
Does customer shakes the toner well before placing it in machine?
Perhaps he stores toner on a heating device, so toner get clounged in the bottle easily?
Were those 2 lines on the earlier pcu's on exact the same location as now?
Also I think the thought of Mika is interesting: Chunks of metal, plastic,... in the pcu.
But how does it gets there?
Some customers shake the toner bottle when near end pops up, maybe this one shakes the black pcu?
You never now these days...

Re: MP401 Somethings fishy here.

I have been told that this model has been discontinued. If so, could that be due to these issues with the drums?

Ricoh just announced it's sucessor the mp402, but they take the same drum cartridge number.
