ricoh aficio 3035 grey page

[cristian]

I have at prints and also at copies, the pages with a grey background, 2-3 cm up and down the page . I have replace the developer , the drum, make all the autoadjustments(developer init., ID sensor 3001 -2 etc.), i have cleaned the sensors,the drum case, the fuser rollers, but the same quality... Also the belt is covered with a thin pelicule of toner.
I have changed the drum and the tank to another machine , it starts with few good pages and after that the same thing, more and more accentuated.Any ideeas ?

A few things come to mind:

Correct developer?
Charge roller making proper contact?
Developer ground properly placed?
Is the mag roller dirty/worn?
Transfer and its blade also replaced?
Did you also put in the second cleaning blade? If so, remove it as all it does is kill the charge roller?
Any marks on the charge roller?
You mention changing the drum and developer, I'm guessing you did all of the other associated parts (charge, charge brush, drum blade, etc)?

Charge roller making proper contact?

Sounds like this is a good possibility from your CQ description. Make sure the flat springs are making good contact.

hi

the charge roller make like this shadow

Most likely the mag roll is coated over. I would expect a charge roll to give a very dark to black image with insufficient contact.

If there isn't charge roll contact then teebee is correct, you will get black copies, however, in the original post it mentions every 2-3cm, and progressively getting worse, this sounds like contaminated charge roll to me. But it could be the mag roll contaminated too, did you clean the mag roll when you changed the dev? Also, wrong dev was mentioned, the correct dev for this model is B0799640

If by this you are meaning a band repeating every 2-3 cm, I would say look at what ever has a circumference of 2-3 cm.

I will add a scan of a print page.
I have replace the whole developing section (both the developer tank and the drum )and also the belt section with another ones from a good machine.The quality is the same-bad. So i think the problem is somewhere else...ID sensor - even if i have cleaned it. The significant observation is that> on the belt, after the copy, thereResize of scan.jpg is an uniform pelicule of toner- also on the changed belt.Also, the quality is worst on the backside of the paper. On the first side, the quality is much better, almost good.

I agree with everyone else posts.
Otherwise see if the Bearings are shot in the dev tank causing metal shards. This may cause the dev bias to ground on the doc blade ? I have seen this on some of the old machines.

From looking at your image of the copy, I am assuming that the paper was fed LEF and that the background areas are on both edges. Something is causing either charge or uneven development. Check the grounding to the drum shaft and development doctor blade. You might have a slight warping of the frame.
