ricoh 1022 ghosting

[ash_572]

reprints the previous page on to the nxt page very faintly. have al;ready replaced the hot roller and pressure roller. both are correct parts for machine and genuine. also the green pressure handle is points up. the only thiing i can think of is the cleaning roller. wat else can it be?

Are both Lamps ok?

Which hook are the springs on?

Are the two plastic guides which hold the Hot roller bearing in place intact.
These often used to snap.

Is the ghosting from the hr or could it be to do with the PCU?

[ash_572]

both lamps should be ok. if one is down then an sc code is activated. i also adjusted the srings on to the second hook for more pressure.

PCU / Charge Roller can produce such a thing in certain conditions.
Don't forget to check if the bushings of the Press Roller are worn.
What about the fusing temp ?

I would go with the PCU. Try to inter change the unit with another & check. It's hard to imagine that the heater would give a faint image of the previous page. It's more probable that one would get a repeat image of the same page in gaps of the circumference of the heater roller. Also I would try checking the quenching lamp as well. hope this helps.

fusing temp and thermistor can be an issue, also check to make the pressure bearings are seated probably. check PCU also

I had the same problem on a2022 recently, I changed the pcu(type 27) and the issue was fixed. On the mid size machines ghosting is 99% pcu related. Good luck

True about the lamps that you should geta code
But have seen normally on larger mcs a lamp fail
And somehow the copier carry on. Particularly if
A engineer fiddles with sp modes. Pcu sounds the one to check out imo

I'm thinking PCU also, The life is 60K and the closer to that you are the more likely it is.

[petrus]

in other model ,the poor quality of toner also can cause this problem.

Like all the other posters are saying go with the PCU.

A tip I use ( Hope I'm not telling you how to suck eggs)

Get your sheet of paper with the ghosting image on it.
Roll it into a cylinder shape so that the ghosted image lines up with another part of ghosted image on the document and this will give you the size of the offending roller/pcu. So you can now go and rule out either the fuser or pcu.

I just did one of these last week for a new customer. It was only ghosting on the first 3 sheets in the mornings. So I go out there and the green flippy thing is in the down position. I flip it up. Copies look good and out the door I go.

So they emailed again this morning with the same problem. Weird. If its not the green thingy in the wrong position, I'm assuming you guys think it is PCU related even tho it only does it on the first few copies of the day?

green flippy thing

Dont try any of that fancy technical talk sonny.

Follow techspecs advice to determine if it is the fuser or pcu that is ghosting. Either can cause it and either can do it only for the first few copies.

green lever down is envelope position< it lessens fuser pressure. It also causes toner buildup on hot roller if left down> replace the hot roller and press roller

So I go out this morning (it took 2.5 hours to get there. Thank You D.C. traffic)
By the time I got there it was fine. Of course.

She showed me some copies and they went like this.
copy 1 light(like under toned or under charged) and ghosted
copy 2 darker and ghosted
copy 4 even darker and less ghosted
copy 4 nice blacks slightly ghosted
copy 5 fine

copy #... fine all day long.

I cleaned off the charge roller with some, with what I like to call "spit", and lots and lots of black came off. The fuser rollers look fine. The PCU is new-ish, but I'm not averse to putting a new one in if necessary.
