Ricoh MP 6002, MP7502, MP9002 Family Series, Lights or low density Copies or printing

have you already used the cleaning rod on the drum lenses?
guess you know that these have been discontinued?

Martini series B/W don't have one. One screw and a retainer bracket and the entire glass slides out,

What kind of volume and coverage does this machine do? All my 6002 machines were low volume and low coverage and they sucked big time. We tried everything on them. Basically it comes down to your DV gets destroyed by toner that is tumbling around in the DV unit, it looses it's chargeability. Your DV unit has tons of toner in it but it doesn't stick to the DV anymore and it just splashes out onto the drum creating a CQ issue and causes low density. If i could get 100k out of the DV i was doing real good.

We tried turning on toner refresh and cranked that up. It took out the transfer belt.

There is a bulletin that talks about this, it's a mix of shit paper and low coverage. You can go into the 8000's service mode and check your coverage averages.

The other offices had them in schools and they loved those machines in that environment. Apparently they ran really good.

I'd much rather have a IM 6000 than a 6002 frame. Super fast to PM and none of this crap mentioned above.

Target Reliability was 25K monthly average for the 6002, 40K for the 7502 and 70K for the 9000. Recommended end of life was 5 Years or 9000K prints – Whichever comes first. They were first produced 12 years ago. Under utilization will destroy most machines.

OK. I thought they were 2 separate units.

They are. Dev unit and toner supply unit.

i had a problem with low density about 200 pages after developer change, but in my case forced toner supply feeded to gray background. In my case probably too warm stored original 9002 toner was the reason for this problem. Now I reduce the amount of toner in the bottle by half - i fill 1/2 of the new bottle into an empty one. So the toner dont stay so long near the fusing unit (low volume usage machines). If you shake the toner bottle with toner that produces low dencity prints, the flow is different from good ones.
Maybe low density problems are more usual with original Ricoh toner in Europe. There were Ricoh information about lot-numbers of toner wich could produce low densty.

A long existing problem with toner is how the bottles are stored. To save shelf space, people tend to store the bottles standing upright. This allows the toner to settle and compact in the bottom of the bottle. If they are not then shaken enough, the toner does not flow properly and does not mix with the developer properly.
