Ricoh AF 3025 Ghosting

[Elmtech]

Hello,

I have ricoh af3025 which had a line in the feed direction on prints. Found it was the pcu. After replacing the pcu with a new genuine part and new developer everything was working ok. After a few days the customer reported the machine was intermittently ghosting the image or over toning quite alot. Went out ch3cked everything i had replaced, cleaned the machine and tested. All was OK. I never saw it fail while i was there.
The problem is still happening does anyone have any ideas in what may be causing the issue?
Sample attached.

Was it a Type 1027 PCU? If so there is a possibility that is is a remanufactured PCU. If so, the cleaning blade could have gone limp. Otherwise it could be the hot roller.

Old machine.
B/W machine.

You said you replaced everything.
Did you refurb the fuser unit ?

Does this machine have the transfer belt unit assy? Try vacuum all old toner out of the transfer unit.

Re: Ricoh AF 3025 Ghosting

Thanks for all the information so far. The whole drum unit / imaging unit including new developer powder was replaced and installed according to the service manual. The ghosting issue was not present before it was replaced it only showed up a few days after intermittenty along with the intermittent overtoning. The fuser unit was inspected and looked fine at the initial visit and when i went back to see why it was ghosting so i did not replace it. It was a genuine ricoh part but am unsure if it was ricoh refurbed. I will check the cleaning blade whn i visit is there anything else besides the fuser or cleaning blade to check?

Elmtech: No. It could (only) be caused by a cleaning blade which has not been "powdered" enough OR a bad charge roller (cleaner).
By the way, NEVER use 1027 fuser units in a 3030 or v.v. !!!

ever since AF 1027 have used 1027 PCU in all model updates with no issues.
Sorry just noticed you said 1027 'fuser'

Davel: what I have written there is correct.

Re: Ricoh AF 3025 Ghosting

Did you run developer initialization after replacing the developer?
agree with above using type 1027 pcu much easier than replacing all those individual parts and having it fail early.
that being said if there is any toner build up on the upper fuser roller it can also display this symptom.

I don't have a parts manual in front of me.(...okay then, to lazy to get-outa-me-chair.)
Is this the model where the fuser plastic frame cracks and the hot roller goes a drift and moves sideways in the fuser frame?
The associate problem can also cause the pressure roller to jump out of position. I've seen that a few times.
If the fuser case has failed the entire lower fuser case needs replacing.

So, if I'm understanding correctly, you bought the B209 3001 or B205 0151 unit PLUS developer that needs to be added manually, rather than just popping in the type 1027 PCU (#411018) that virtually everyone uses? That's a much more expensive route, with no benefit at all.
Only the 1027 units could be the refurbs that others are referring to.
Again, you've told us that you installed the developer per the service manual, but did you calibrate it? It sure sounds like you may not have

Re: Ricoh AF 3025 Ghosting

I did run the developer initialization to calibrate it. All was lrinting perfectly while i was there. I did not supply the parts for this job was given them by the boss. Just fitting what i was supplied. I am going back tommorrow to check it out again. Thanks for all the information so far

Re: Ricoh AF 3025 Ghosting

Because you had good prints directly after you replaced the pcdu, and the problem came later on, it might be that the toner in the machine is incorrect OR the developer you used is different than dev.28 or B1219645...
