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 ?

Re: ricoh aficio 3035 grey page

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

Re: ricoh aficio 3035 grey page

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

a grey background, 2-3 cm up and down the page

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.

Re: ricoh aficio 3035 grey page

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.

Re: ricoh aficio 3035 grey page

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.

Did you look at transfer unit? Your cleaning blade could be bent or/and whole unit is dirty like hell.

Good. ... but i have put on the machine a dev. tank (from another machine- who works perfect) the quality remain bad. Also i have put the whole drum assembly (from the same good machine) and the same result...

Alright, let's look at other things then.
What are the charge voltage and developer bias set to? If I remember correctly, the charge voltage is automatically adjusted by the ID sensor reading the patch, so you might want to see what the patch looks like, and see what the patch settings are in the charge voltage and developer bias settings as well. You might want to check the settings for the ID sensor, too.
What type of toner are you using? There were two types of toner used by the 35/45 cpm chassis during the time it was actively being manufactured. They are incompatible. One uses a styrene base, the other polyester (I'm pretty sure the polyester based toner is what this machine uses). And if you are not using OEM toner and drums, you might just have got some from a bad batch.
Are the grounding points between the tank and drum unit to the machine in good shape? I had always been under the impression that those faults would lead to light copies, but I recently learned they can also cause something like this.
As far as the toner on the belt goes, the belt cleaning blade is worn out and needs to be replaced. It might not hurt to replace the belt as well. Make sure to thoroughly clean the toner and paper dust from the brush on the belt unit frame when you have it apart.
Hope that helps.

Re: ricoh aficio 3035 grey page

When you swap developer and drum units you still need to do an initialisation. The steps for swapping are in the manual. Also, there was only one type of toner for this model. The replacement MP 3500/4500 and 4000/5000 had two different types of toner.

Aw crap, I was mistaken about the toner, sorry about that.
