Question about Lexmark C510 Laser Printer

Lexmark c510---201 paper Jam helps empty my wallet

I have a "new" relatively unused C510 laser, just out of warranty and printed 1650 pages so far; on any print job cant seem to get through a job without t 201 paper jam error. Seems to happen at random. Did all the basic fault corrections.
On jam -there is no paper jam at all. Just need to open & close rear door press go button and away we go for another awaiting random stopage.
Had Lexmark service (costly!!) and replaced paper sensor; then another service to replace the paper roller - all the while no change in behaviour of the C510 201 paper jam errors - just the thickness of my wallet was altered -now its very thin -I could use it as paper if need be! Finally I'm told that for my $700.00 those "repairs" did not fix it. Now they can assure me it will really need another $800.00 service to replace the engine controller - are you sure? I asked. Well...err...nope, ..Mmmm they think it will fix it - well thats what the manual says!! What a circus!!

Do I have any other options besides using this wasteful purchase as a new spare anchor my boat?

    YEP, It has been happening to me as well ever since I purchased it almost three years ago. I have been shopping now for a new one now, I have decided to just get a inkjet printer. They have really came a long way and I can't afford to waste anytime anymore on my paper jams, which from what I have read are unfixable.

    Yes I am having exactly the same problem also with my Lexmark C510 also just out of warranty and low print count. It started happening a few months ago, it will occassionaly randomly print, but these days more often it will not print. First it will say error 201, then it will say to check rear door. Never any paper jamed. Sometimes just enought to press the go button after the error 201 and it may print. Have checked all paper path and there are no debris to be seen.

    HI Fellow C510ers,
    Well, I can report some great news. I have a solution. Now it does not cost around the $1500.00 mark! Actually, it will cost you as much as 20 cents. I'm so glad I did not pay $800.00 to have a new engine card installed.
    It is along the lines of the posting from the guest on 22nd Dec.
    Yes the problem all along has been the paper sensor flag - a little bit of plastic that tells the system that the paper is in position. The flag jams. Why? Because it has a long plastic shaft and at the ends it has a plastic housing. The shaft must rotate in the housing to let the flag fall back to the sensor. The housing is where it sticks. Put some molybdenum grease (molyslip), a dob about 3 mm long x 1 mm wide, on each end of the flag shaft, at the housing. Swivel the flag and shaft gently until the grease is distributed. It will solve the problem I have described in my post.
    I have since printed 400 pages  without a 201 jam!!!!

    Much apreciated.


  • Chris109 Apr 16, 2008

    Can anyone advise how to disable the sensor in the menue options? I have the same problem with random jam 201 but open and close the door and everything is fine. There is never any paper jam. The plastic leaver is still intact and seems to be swing freely!

    Any help would be appreciated.

    Thanks MACer, lubing that little ****** worked!

    Paper sensor flag
    In case it takes a while to find it.

    Quest: Removing the sensor is not possible, then you get error 241.

The problem with my 510 was that the length of the plastic tab that the paper actually touches was a tad too long and so it got caught. I took the entire arm out, cut ~1/20 of an inch off of the end of hte plastic tab, and viola it works just fine now.

You cannot disable the sensor...its connected directly to the motherboard. The sensors no matter what manufacturer are black, therefore, hard to see!
a tiny bit of black gold, gear oil will help!
we have a Lexmark form printer that is sticking, & a tiny...and I DO MEAN tiny drop of oil, does help.
3 in one oil does wonders.

Some pictures
Thanks MACer, that solved my problems, here's a few pictures where you can see that paper sensor flag.
I thought it saves some trouble to find that thing.

Removing and unplugging the sensor is not an option, tried that and that caused error 241.

Posted on May 20, 2008

I daily repair Lexmark printers and 2 models that I work on have the same issues and in this case it turns out that the exit sensor is the issue though it is not the sensor itself. What I have found to be the problem is the sensor switch it has has a thin long arm that the paper trips and if this has been broken then the paper passing won't activate the sensor (usually this arm gets broken when there is a random paper jam and the toner and photodrum assembly are not removed before clearing the paper jam) Now there is a newer model that I have started seeing with a similar exit sensor issue but this on is just that the design is so bad that I recommend that the switch just be removed because it is just garbage and unplug/disable the sensor from the options board. Hope this is helpful.

My Lexmark C510 keeps popping up with a Paper Jam 241 error in Tray 1. There is no paper jam. I open the printer door take the tray out, put it back in and shut the door. How can I fix this problem? I...

I have a Lexmark C510 colour printer: Manufacture date June 2005.
I had been getting the "Paper Jam 241 error in Tray 1" message for some time. Sometimes it would print just fine but in the past several months, it's been bad. I'd pull the tray out (notice roller marks on the top sheet that was only partially fed), reinserted the sheet properly into the tray and try again and again. The techy at Lexmark mentioned that I could purchase a new rubber roller that feeds the sheet but that I might first wipe down the roller myself as they get worn and old. I first wiped it down with a damp cloth to clean it then thought to try reconditioning it with leather conditioner we'd purchased for our couch (I'm sure Amourall would work just as well). Voila, the old, dry roller was picking up paper again. Just open the rear door and that grey roller (it's black again when you recondition it) is at the bottom. Hope that helps.

Printing blank pages on Lexmark C510 printer. Throws a 34 Short Paper error first, prints out a blank page. I have replaced the black toner, but problem continues. Demo page printed colors successfully but...

For 34 Short Paper error, reseat the tray guides and make sure it is set properly. Also, set the correct settings in the computer. For blank pages, always double-check the paper settings and again the settings in the computer. For not printing black, print the Print Quality page and see what color is not printed or not showing. If Print Quality shows black, try printing any document from any application in the computer. Check if you still have the problem. If problem is not resolved, leave a comment so I can get back to this.

Lexmark E 342 n paper jam with error code 201

According to the LexMark support page, this is most often related to not getting the print cartridge assembly properly positioned. (Left and right sides not fully in place). Another possible source is paper in the output tray when using the double sided printing feature. (This leads to grabbing an extra sheet when it tries to retrieve the paper to print the second side. Paper stock thickness will change the number of pages printed before this happens.).

I hope this helps.

My Lexmark C510 keeps saying paper jam and has hardly grabbed the paper out of the paper tray. Also says "short paper". I called Lexmark who told me that I needed two parts: a paper feed roller (56P1655)...

If service were required, Lexmark would have offered to place the service call for you.

Go ahead and order the parts, if they look to complicated to install, then you can place a service. Most "C" level color lasers require on-site service and should not be taken to a dealer.

Fuzzy prints, paper jam

If you would like the service manual reply with your email address (it's 5.87mb).
Your first problem could be caused by one of the following, feed roller from the paper tray is slipping making the paper to leave the tray late causing the registration sensor to flag an error because it hasn't detected the paper quick enough or the registration sensor is just not working, could even be the paper feed clutch or registration clutch. I don't think the problem is with the thin rollers.
The second problem could be a few things, possibly a consumable, i would start by swapping the consumables over between the two machines, transfer unit, transfer roller, cleaning roller, photo developers, fuser etc, if that doesn't cure the fault clean the hv connections. This problem is related to the high voltage so investigate in that area.
Sorry for being long winded, but without being in front of your printers its a bit of a guessing game.
