I had a paper jam & took off the back door & got most of the paper out but not all & can't see where it is & therefore can't get it out & the printer keeps telling me I got a paper jam. What can I do??

Try to take out cartridge and the drum. look inside.
Sometimes if you open rear door and look inside and remove the paper

Here is a link to a detailed description from HP.

I have a ML 1710 .Not my area of expertise but I took out the paper and could not see a jam. Took toner out , a little cleaning, plugged and unplugged from computer several times. I found paper jammed in the very back ,folded so tight nothing was showing. Mine has a back door and the paper is having trouble rounding the last bend and coming out. So I leave the back door open to get my copies. Green light on.

If this printer has a back door to open or take off, open it and rotate the large rubber rollers til the prongs go back down, after you power up again it should be OK.

open the back door,see where paper jam,could be wrapped around fuser.if no jam,fuser or output sensor faulty.

Hello sir;Track back the paper you pull through you will find a senser either stuck or come off, put it back property.

most likely the sensor on the paper path out of position, chech it out and put it back to where it have to be, good luck!

At the back of the printer... open the feeder door and slowly remove the jammed papers.... put it back and put some paper in the tray and press resume button... this will continue printing the remaining print jobs.

good luck... happy FIXYA...

hey, give this a shot

1. Turn off the printer.
2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
3. Also open the back cover of the printer if this model has one.
4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
6. 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.
7. 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.
8. 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.
9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
10. see alternative if the problem is still not solved.
    

alternative :
Load 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.
