Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
How old is the Sharp printer in question?
Where do the jams occur?
What is the error message or error indication on the printer, exactly, when that happens?
That is most likely to be a problem with the fuser.
The fuser is at the end of all laser printer, and laser copier, printing processes.
It applies heat to the paper, which fuses the toner powder onto the paper.
Be careful when examining the fuser, and turn the printer/copier Off first, and wait 15 minutes, to be sure of not burning your fingers - fusers are quite hot.
It can be fixed. Replacing the fuser unit, as a unit, is the usual cure.
Also, if the rollers (there are several rollers in it) are obviously out of place in the fuser, or damaged, upon inspections, then you can do various things.
Offhand, I'm not sure what is wrong. If the paper has completely exited the printer when it jams, then make sure there is no paper elsewhere in the printer/copier.
Also, try copying *one* sheet. See if that fails to jam the printer.
If a one-sheet copy completely exits the printer and exits the fuser into the output tray... then 'a misfeed has occurred' means something else. E.g. a stuck sensor switch somewhere, or an erratic circuit board.
But I honestly am not sure. Would it be OK if I Opted Out and let another Expert take over this case by and by?
I can't picture that. How far out of the printer does the paper get? inches? at all?
If the paper has just exited the fuser but stops there and doesn't get deposited into the output tray, then a sensor switch that detects the presence of paper in the fuser, may be being activated, but not 'springing back', either sticking in place or otherwise not 'releasing' after the paper leaves the fuser.
If that sensor switch is in the fuser unit itself, in this model, then replacing the fuser would cure it.
Do you mean, the error is fixed if the output tray is removed?
Then somehow it was fouling up the fuser region. Or not inserted correctly.
Or perhaps the fuser unit was malpositioned. And fed paper out to a place where it was blocked from exiting properly.
Or the exit feed rollers are not turning because the fuser is malpositioned and gears are not meshing that drive the exit feed rollers - ?
I'm examining those photos...
Thank you for taking the photos and posting them - they provide more data about the problem.
If there's a stapler after the fuser, then the problem is in the stapler, doubtless. Check its connections to the rest of the printer.
(If a sensor switch in the stapler was disconected, then the machine would sense a misfeed or jam and stop, just as it seems it is doing.)
