Ricoh MP 2550 - Light Copies

[printsnow]

Well, spoke too soon!!! Now we have light copies again and the toner isn't fusing to the paper! This thing is about to get used for target practice!!!

Check the toner hoper unit take it apart and see if you have the four plastic seals in place, sounds like some of them may be missing not all because you say that you can force toner. Thats my idea

Do you have any samples before and after the new PCU ?

I'm assuming you are using a recon-PCU Ass'y or a completely new factory unit ?

No fusing is H/R pressure and temperature, unless you have developer jumping onto the page.
Dev on the page gives the same effect as no fusing. Dev on the copy can be caused by a paper jam or someone or something reversing the dev tank.

If you do a half page sky shot and stop the copier(on/off) and check the PCU, is the drum nice and black ?
Do you have a charge problem ?
Do you have correct transfer onto the page ?

Where are you getting your toner from?
If it's not OEM Ricoh toner then your problem could be the generic toner.

I won't be able to get there till tomorrow, but yeah, we went ahead with factory PCU, to rule everthing out. We use OEM toner, I don't have any samples, because it looked great when I put the new PCU in, the other prints before just seemed to fade out after a couple of days when we rebuilt the PCU and then when we put a brand new one in.
