Paper with a grey tan.

[coopers1305]

I've had this a few times but never figured out what the cause is. Prints come out with a grey tan. Not really sure how else to say it.

A blank copy or print has a grey background but prints normal otherwise.

What do you guys think?

Can you give us a hint to model, please?

MXM363N, MX2600N, MX3501N, but most recently the MXM363N.

OK, B/W and color - can you post a couple of samples?

Re: Paper with a grey tan.

I've found this problem with mostly B/W machines.

I don't have any examples at this time but just imagine a white piece of paper that is white as normal on one side and the printed side is slightly gray with no white, not even margins. The grey is slight but enough for some customers to call. I think it looks textured up close.

So it's a background issue; look at laser or HV problem.

Any more info?

Does this happen on prints only? On a copy run are all pages faulty or just the odd one?

I don't think it's laser - the laser would need to write all the background data. Maybe losing charge from an arc or poor contact - it's not unusual for a dirty charge unit to arc and drop the drum charge so much that the dev gets pulled onto the drum - could be the 'texture' you describe? In extreme cases the machine can empty the dev unit in a couple of minutes. Look out for a 'herring bone' pattern on solid fills as an indication that you're losing dev.

You can try to run 44-27,44-6,44-26. Then run auto calibration. This brings them bac sometimes but if not. Change your developer. When running DV mix make sure toner is out of the machine. Hope this helps.

Thank You ayeright, this would explain why when I do maintenance the problem goes away. This is the answer I was looking for Thank You.

Re: Paper with a grey tan.

just ran into this problem on a 503.Internal prints/copies come out fine but there was a grainy/greyish even background.check the dev bias, sim 8-1 to adjust. hope this helps.
