aficio 2060 can't keep a good and quality copy

[shlo1]

hi to all
the black areas look gray.
we use original developer .
katun and aeg drums (katun two versions)
and original and non original toner.
it show 4v and 0.4-0.5v vsp and vsg.
we replace the developer it is o.k. for 10k-40k then we loose the quality again.
we have the same problem with most of the 2060 2075.

thanks

Is the mag roller blacker-en? Also have you tried changing the Drum as the dev may just be compensating for drum wear (or just being katun). If your using a mixture of different manufactures of drum/dev/toner etc, you will not get as good quality as the mixtures and voltages they draw will not be in tune with each other. so after a while the dev may be taking a strain coping with the drum and toners. Service it with Ricoh family parts see how long it last and it will prove a point... or not, you will have to see. But replace all dev/toner/drum together.

What do you mean with loose quality? Does it fade out or does it get too dark?

[shlo1]

the black area is not black its look like you have to change the developer

[shlo1]

we use the same parts in aficio 700 1055 1060 mp5500 and we dont have problems with copy quality

[Herrmann]

ok, so there is a problem with the toner adittion, i think. Does the toner bottle rotate? Are you sure, all connectors in front of the developing unit are ok? There is a Motor/Clutch Assy in the back of the unit, the motor drives the developing Assy, and the clutch is responsible for adding toner, have a look at this

[shlo1]

the problem with about 30 machines

[iMind]

Open up the transparent cup on top of the development unit, check too see if the two little seals that feed the toner into the unit are there, they peel off quit often clean "vacuum" the metalic filter that may do the trick...

I would have to agree with Ayjayaredii about the drum. An old drum on these machines will cause background and poor solid fill. However, if the drums are fresh and this problem is on 30 machines, it almost HAS to be a problem with the toner or developer being used.

Check the drum earth, change the drum shaft / hub assy.

Another vote for Toner Filter on dev unit and make sure to clean the doctor blade

its a service problums you must check you magnet roller and clean with thiner or patrol you must solve your problum

!!!!! IF there is toner on the roller just use the old dev as an abrasive before changing it!!!!!!!!!!

Doctor blade would cause stripes, check the drum earth!!! if this is bad you WILL see the copy going grey as the process control will be buggered! The drum discharges through the shaft bearing and these dry out and increase resistance preventing the laser writing the full density.

Try with Ricoh parts only.. or Katun only.

I would try to use Ricoh parts, toner and drum and see if that does the trick. We have plenty of those machines out - and they work really good. We only use original Ricoh toner/dev/drum etc and it manage 300k without any problems. Some does 600k between each dev change (but prints tend to get grey towards the end of course).
We used Katun on other machines before, and usually it worked OK - but once in a while there was combinations that didn't work at all or worked bad over time. Sometimes the problem would come after a firmwareupgrade too. So try the original stuff and see it it does the trick. Or use Katun on all parts and see it they are a good match . .
