The printer came in originally with a paper jam message. I took it apart to see what sensor is stuck, because no paper was in it. I found the sensor wheel out from the sensor path. I realigned the sensor wheel, and now I get this message error "Turn Power Off and then On." Any suggestions?

Fuser Door Open is the message on the display when it's powered on. I took the back apart, removed the fuser, looked all over. I couldn't see any kind of sensor, optical or mechanical that makes when the door is closed. There's an access plate with a blue latch below the fuser that makes an optical sensor and a mechanical sensor, but that seemed to be OK. It didn't seem like something that would be called a fuser door. So, I pushed on it where it made the mechanical switch and the printer hummed to life and the message went away. I took the fuser out and examined it. The metal brackets where the pivot parts were, seemed a little bent. I straightened them out, stuck it back in and that fixed it. By moe who hasDell MFP 1850DN this might also help... or
Fuser Door Open
1. Make Sure the Paper Tray is Loaded Correctly With no Obstructions
2. Clear the Paper Jam in Tray 1 or 2
3. Clear the Paper Jam in the Multi-purpose Tray
Great job on taking out the paper jam without tearing it. Maybe the sensor got stuck and printer keeps thinking it's still has a paper jam. Remove the ink cartridges from the printer. Close the cover. Unplug the power adapter from the printer. The power adapter is the rectangular black box behind the printer where the power cord is attached. Wait at least 30 seconds before plugging it back in the printer. When the printer's ready, reload the cartridges then close the cover. If this doesn't help, I strongly suggest you contact Lexmark technical support to further investigate the problem. Thanks
Start by following the steps below to get the paper out from the machine.
Turn off the printer.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Also open the back cover of the printer if this model has one.
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
If you find a piece of jammed paper, remove it by
holding it with both hands and pulling firmly. The goal is to keep the
paper from tearing. If several pieces are jammed together, try pulling
out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do
this step especially if the jam message comes up repeatedly without any
obvious paper jam, there may be a small tear of paper inside.
Ones the printer is free of paper Replace the toner or
ink cartridge and paper trays, close any doors you opened and turn the
printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
see alternative if the problem is still not solved.
a piece of thick paper, for example photo paper and press the resume
button (may be diffrent button on diffrent models) a few times to the
printer picks up the paper and puts it through the machine.
that doesn't help then you would have to start taking apart the machine
to find the jammed paper and remove it, its not something a just anyone
should do unless you have experience.
you may have to take the
machine to a repairer to get the jammed paper bits out of the machine,
if you don't see paper jammed in the machine it does not mean that
there wouldn't be a paper jam somewhere in the unit along the paper path. Some of the switches or sensors might have gotten stuck.
I just completely took apart my front feeder unit because I just didn't believe there was a paper stuck in there. Sure enough, when I got to the bottom (an hour later) there it was- and it wasn't from the paper that was jammed. It must have been floating around in there waiting to get in just the right place to block the little sensor wiggly thing.
After I got it out, I realized there was a MUCH easier solution--- get some heavy paper (I used cardboard folded in half) and manually feed it through the paper feeder in the front assembly by hand. You can see where it should go in (it's where the paper from Tray 1 goes in) and out (it lines up with the belt in the main body of the printer) and there is a large gear on the side you can turn to help you get it through (just turn the gears until you feel the one that grabs your heavy paper.)
As it comes out, it should have your stuck paper with it.
HP LaserJet 4, 4m, 4 Plus and 4m Plus Series Printers - False Error Message 13 PAPER JAM
After clearing all jammed paper from the HP LaserJet 4, 4m, 4 Plus, or 4m Plus series printer, the display still reads 13 Paper Jam . Even after cycling the power off and then back on, the error remains.
Open the rear door of the printer. There is a paper sensor near the upper right hand corner of the fusing assembly (just below the right edge of the long yellow warning sticker on the fuser) that can cause paper jam error messages even when there is no jammed paper in the printer. Toggle the thin black plastic lever up and down to make sure it is not stuck or sticky. The lever should be in the down position before closing the back of the printer. If the lever is stuck or missing, the printer will generate a false paper jam message.
Hope it will help you !
This worked for me. If "Paper Jam" error message continues to appear after jam has been cleared, turn off power to printer. Navigate to Control Panel - Printers, right click on HP Photosmart 2570 series icon, click on Delete on drop down menu. This deletes printer from your system. Turn on power to printer. Printer will re-install (may need original installation disc, may not). "Paper Jam" error message should no longer appear.
There is a limit switch on each side or some models its located by the cam. If you took apart the can assy then the units out of mechanical timing and you are gonna need a service manual for this. If the switch is not working on the side I myself forgot to plug back in the small plug on the curcuit board. Good Luck
