Does anyone know where, if possible, to get a charge roller or assembly for the drum units. I am sick of replacing drums because the charge wont stay clean. Its costing a lot of money. Any help would be appreciated

Would be nice for Ricoh if they would just issue a part number for the charge roller assy. But then again they wouldn't make near as much money that way.

I think if you changed the charge roller it would get dirty too. The cleaning blade is letting toner get past it. I have also seen the DV get over toned causing the same problem.

i'm just surprised that there is no third party supplier who has figured out the specs and got these on the shelf.

Are you using genuine toner? We've never had this charge roller issue and change the drum units on the PM life of 80k.

drum units always lasting 80k?

You must have good karma, zyqwiz. I went to the Ricoh school on these machines and I've had to do many of these drum units before their time due to the charge roller/cleaning roller assy's getting worn out. I wish I could make my own third party assemblies since Ricoh won't sell them. I could make a fortune.

p.s. +1 on avoiding generic toner!! we bought one batch of generic and it took out three drums and their developer also on one machine due to massive overtoning.

[zyqwiz]

I know the toner we use over here is different to yours (the genuine type).

There must be something is US toner that sticks to the charge rollers compared to European toner - if you look back at where people are that have the major problems, its always over your way!

Try this

There is a plastic shaft in the cleaning unit auger that can be causing a backup in the unit. This can cause the charge roller to end up getting dirty. Clip out the shaft but leave enough of the shaft to drive the auger.

Apparently there are no plans to release the charge roller as a separate part, probably because the drum will do double the life and Ricoh need all of the money they can get their hands on these days!

Ricoh need all of the money they can get their hands on these days!

They are getting it since the universal price list came out - printer consumables with the DTP higher than the RRP!

They're taking the piss, aren't they?!!

Ricoh will rectify this situation eventually. Just as soon as their market share starts eroding, which should be any minute now.

Honestly, somebody needs fired in the engineering department: The MP3500 thru MP5000, Piss Poor reliability on MPC4500 type PCU's, the MAJOR step backwards with the MPC7500's, Pulling the Type 27 PCU and making us rebuild those junkers - and we end up replacing them every other PM anyway at 6 times the cost because they don't last worth a fart in a hurricane.

The Itsy Bitsy desktops still work pretty good, and the the 60PPM and up B/W and C900 color are still rock solid. I just hope they don't screw these up - the big monsters are mostly what I work on.

At the risk of hijacking this 'ere thread, Ricoh do seem to be out to bleed the dealers dry. Most likely, further to their purchase of the likes of Infotec and Ikon, the little people are not a necessity and can be held over a barrel financially, however you're right in saying that some of their products are pretty shaky these days.

Having said that, the 35 and 45 mono boxes have always been dirty beasts.
