MP201 previous job shows up on new print job partially

[Counsel]

Hey Everyone,

I have something i have never run across before. On this machine if I print something like say a counter sheet then make a copy of it on the new print about a 1/4 of the image from the first one is printed on the bottom half of the new one. it can be printed or copied it doesnt matter if one job is printed on the next job the first page has a small portion of the previous print job on it. However if I print an SMC report or multipage document all the pages within the same job are fine, it is not until a new job is run that an image carries over to the first page of the new print job.

Initially there were also lines once in a while like a failed laser unit would make, i did try a new laser unit which solved nothing. I am leaning toward this being a ram or Nvram issue, because it happens from one job to another and not from one page to another it seems like its not clearing information from one job to the next completely. There is not an HDD installed just the ram card, this was a rebuilt device and it ran fine for 4000 pages before this started happening.
It has less then 5000 pages on the machine.

Any ideas what would cause something like this.

I am not discounting your powers of observation, but couldn't it be simpler? Like a drum that's not cleaning, or a fuser roller that's not cleaning? All of those choices are considerably more likely than some rarified NVRAM or image processing problem. Keep it simple stupid ... (if at all possible).

Years back we had a Sharp desktop MFP ... I think it was the AR-F152 ... at any rate, when it awoke from sleep mode the printer would start printing before the fuser temperature reached 180C, then the temperature continued to rise to nearly 210C before levelling out around 180C. The symptom was fuser multiple imaging only on the first two pages after waking up, typically on fax receptions or prints. Some of the similar models got firmware to solve this, but there were machines like the 152 that never really got fixed ... just replaced. =^..^=

Sounds like transfer belt cleaner to me. I've seen Ricohs running with them completely missing, having had the transfer belt replaced by another tech. They forget to swap over the cleaning unit and then are clueless when this happens.

Re: MP201 previous job shows up on new print job partially

I can answer both of those, this machine does not have a transfer belt just a small transfer roller that does not have a cleaner. I know its not the fuser as its not a ghosted image repeating, its limiting specifically to the bottom 1/3 of the page, you can also put the counter sheet in bottom first and receive a reflected image on the page if the previous page was top first coming out. There is also no fading at all it is a 100% perfectly dark image. The drum on this machine makes about 5 complete revolutions to produce an 11" long image which would mean if the drum was not cleaned you would see the image repeated from top to bottom multiple times not specifically the bottom 3rd as it would have made 2-3 full turns before getting that far down the page. It would more likely be on the top half of the page once or twice if it was the drum not cleaning. believe me when i heard customer say duplicate image i showed up fully prepared to rebuild the fuser. Both the fuser and drum have under 500 pages on them as it was rebuilt for this customer 25 days ago.

Does it have removable image memory? I might try re-seating any memory chip, or replacing. Smaller tabletop MFPs often have the memory built in, which would point towards either an image memory clear (if possible) or controller board replacement.

Sorry I can't be more specific. I haven't spent much time with Ricohs in a decade & 1/2. =^..^=

Re: MP201 previous job shows up on new print job partially

It does have a small PC type ram card 512mb like a ddr1 stick, i did remove that and cleaned the contacts, i also removed and reseated controller board, and removed the nvram chip and reseated everything with no effect. I also did try a printer memory clear that didnt do anything either. So i am not sure if the image is stored to the 512 ram stick or if there is onboard memory that saves that data between jobs.

By bottom do you mean the trail edge as the paper comes out?

Re: MP201 previous job shows up on new print job partially

Trying to get my noggin around this model machine. I believe they are same as MP171 ???
First impression it sounds like Drum quenching lamps are working intermittent ...yes ...no...
Check the quench plug and or PCU contact ground?

Re: MP201 previous job shows up on new print job partially

Correct slimslob, by bottom i mean trail edge, the previous image from previous job covers about 2 to 3 inches of the trailing edge portion, this machine only feeds SEF and 8.5x11 or smaller from standard built in tray they dont have the additional tray unit for larger, only the bypass.

I did question quenching lamp but even if intermittant i would believe that would cause a page to page problem such as a 10 page document having 1 or 2 come out funny, this image occurance only happens from one print job to another and only on the first page of the new job the pages following the first sheet no matter how many are fine until a new print job is entered.

Check this with the right driver ricoh mp 201.(pcl5/6)201.jpg

You probably don't have a hard drive, so when you scan something it is temporarily stored on the ram. I sounds like the buffer where the image is stored is not being totally cleared out or overwritten by the next scan. It could possibly be a bad memory dimm.

Re: MP201 previous job shows up on new print job partially

if it does the problem on the counter page its isn't driver or PC related issue Just replace the PCU simples those PCUs only do 40K anyway

If replacing the PCU does not correct the problem, then you are possibly getting memory corruption, of HDD corruption if it has a HDD. Use SP 5801-004 to initialize IMH, IMage handling. If there is a HDD installed then SP 5832-002 will format the IMH portion of the HDD.
