Thank you for sending this Tech Notice. Looks like what I am looking for. If you have one in English, that would be appreciated but I can probably OCR this and then have it translated. I really...

It appears I now know why this hook that holds the side door on both the C300 and the C400 models was broken: I was working on a C400 because the duplexer door (right side) would not open. I was...

Thank you. I appreciate your assistance.

Thank you for your reply. I was trusting the Samsung service manual for info on the A1-4111 error and (at least the edition I have) says it means "the transfer roller can't move the engage/disengage...

The Samsung service manual says that the cause of this error is "The transfer roller can't move the engage/disengage position". It also says the remedy is to first replace the feed drive stepper...

Did you ever get a solution to your problem?

I have a C1810W that has a "transfer roller can’t move the engage/disengage position" error A1-4111"

I have replaced the feed motor and main board...

I've Googled the part and checked eBay and no joy. If you know a dealer or distributor who sells Ricoh parts, please contact me. Thank you.

part# D0CB4608 is just a small hook or latch to hold...

Thank you for your detailed response. I had located & downloaded the manual and I have the part number I need, but the local dealer will not sell it without also charging for a service call. I'll...

I don't normally work on Ricoh so I don't have a source for parts. I am not Ricoh authorized, but hoping someone can help me out with a source I could order a simple door latch from. Thank you for...

Thank you. I'll give that a try.

Thanks for the help, but I have already determined that the ghosting is caused at the fuser... the fuser roller has picked up toner from the paper and relaid it back down. The fuser must not be...

I have replaced the fuser on this MFP but it has not solved the issue with ghosting after about 15 to 20 printed pages. I think the fuser roller temperature is not staying constant which makes this...

Sorry, I forgot to mention that the engine test also has the same problem. It starts about 3 cm down and runs off the bottom of the letter paper. Also it doesn't matter if the paper comes from tray...

I'm working on a color Laserjet 2840 that, even with an internal test page print, prints to low on the page. There is no bottom margin, the start of the test page print is 2" down from top of letter...

It has been a few days since my last update and maybe you all have given up on other ideas to help. I found a used main logic board on ebay so decided to give that a try. This unit has been off for...

Another try at attaching PIX

There is a difference between the ADF copies and the flatbed copies, but I don't see a difference between first and last pages. I will attach a photo with 3 stacks of pages, the left is flatbed, the...

I have performed many scans and copies since my last reply and it appears that the scanned images do not have a problem, so I am back to the original problem of determining why copies come out grey...

If the white reference plate is in the area between the DADF window and the flatbed window, it was cleaned since I cleaned the underside of the glass. I just checked it again and the white part...

The scanner ribbon cable looks really good. I reseated the cable, but still have the problem. Any other ideas? Could the problem be in the main board where the ribbon cable connects? Any way to...

Print jobs look fine and so do internal reports. Copies are the poorest, but scans also have a slight background shading problem. I have cleaned the CCD mirror and both sides of the scanner glass...

I have found that scans have a slight grey background, but nothing like the copies that seem worse the last 1/3 of the page. This darker 1/3 happens when using the flat bed glass for copies. I...

Thanks for the help. I will check the lamp and mirrors, however, I would think the scanned image would also show the problem if caused by the scanner unit. This may take me a few days to determine...

Thank you for the ideas. Keep them coming, please. I have copied using the ADF and still have a grey background, but it is more evenly distributed down the page. The flat bed copies had a darker...

This is why it is so hard to determine the cause. The initial, auto printed config report, is the only report that comes out dark (sometimes). The copies always have the problem on the bottom third...
