If it’s the dev unit you can try and clean the mag roller. To rule out the drum unit you can clean the drum charger/drum or swap colours to see if the lines move to another colour? Do that first....

Are you talking about cleaning them in a bath during a refurb or general cleaning in situ? I don’t do refurbs as I’m a field tech and I use foam cleaner generally with WD40 for stubborn marks. I am...
I found one here:
Ricoh DD3344 service manual
This was late in the day but did you try the paper which could be damp? Or paper guides in the cassette. Alignment issue along the paper path.
Seems as though removing all connectors on the controller board and re-seating would be an idea. You won't be able to flash firmware if the machine is not in a ready state unless it shows up on the...
Did you really clear the counters or just the supplies usage information?
I know Lexmark would not be so simple as to leave such an easy loophole to reset all counters. Even other manufacturers...
It will also depend on the paper type settings. Heavy Paper or other paper types will slow the machine down too in addition to the settings already mentioned.
If you change the paper type to slow the machine down this could help but the fuser units may not respond well to compatible MICR just like any other compatible. Have they tried using Lexmark...
I don't think Lexmark publish a life expectancy because it is a printer and not a photocopier with which a life cycle is normally provided. The life expectancy will be the point at which repair...
Lexmark are pretty strict on doing things like this because all four imaging units are replaced at the same time and the counters reset automatically. The image unit assembly is considered a...
It could be the sep clutch but since I’m not overly familiar with this model I can’t be too sure. The sep roller will be in the tray right? There are also a lot of fake HP roller kits out there worth...
To be honest you’ve done well already as an end user but I would not recommend messing with developing units if you are. Removing and checking the fuser would be less intrusive for an end user but...
The way you are holding the sheet of paper suggests the paper is feeding out of the machine short edge first (A4R or landscape). Is that right? The lines suggest it came out long edge (portrait). If...
This might be a silly question but I don’t know where you are in the world. Are you copying a Letter or A4 document and what size of paper is in the trays? It sounds like it could be the registration...
Hi all,
I think I have changed a fair few Lexmark fusers and the c540 looks like the same design as the cx510/cx517 clam shell design. If you’ve ever had to change the Fuser on the Oki MB451 then...
Not all remanufactured toner will cause that issue but they can and the magenta often tends to do this. Try a different brand to see if it makes a difference or swap fuser units just to rule out...
Hold on, isn’t this the machine the opens from the right side in a clam shell design? With the imaging unit assembly containing all four drums and not individual drums that you replace? If so how did...
I’ve also done this once and yeah cutting wires sounds so wrong. I used the old wire to pull the new one through as well. I had the same problem as you as well. Rubbish design. Lexmark don’t seem to...
The ADF restraint pad just clips out with a small flat head. See instructions in the attached image.
Hi, not quite sure what exactly you mean. Does it feed at all or is it intermittent? Never had that exact problem but there should be a clutch of some sort to the Sep roller but if that fails it...
As the previous poster mentioned you should check the laser area and I would say clean the laser dust proof glass first, assuming the white line is in the print direction ———————- and not the scan...
500k is nothing for that machine. As an earlier poster said some maintenance items may be due for replacement. Check the maintenance count for those items just to cover yourself.
I think you can also use 7654321 for the ID and password if you had not changed it. It may still work and worth a try.
All these comments were very helpful as I have to look at a KM5050 in the morning with this very code. Of course, I would have looked up the code and had a think but using sites like this in advance...
Swap the lifter motors from another cassette and then actuate the white switch to the rear of the machine to see if the coupler turns. If it works then fine but if it does not solve the problem and...
