Samsung SF560 error message door open & jam, no toner.

You should troubleshoot jamming error message by removing toner cartrige, check if the little plastic sensors on the paper path are not stuck somehow, reinsert toner,close door, open back door check if the fuser sensor is ok ( and not broken), clean the papertray roller, restart printer and it should work. If that doesnt fix your problem it can be a faulty sensor or some tiny paper left somewhere you can't see and sensor detects .. Hope it helps.

Please follow the directions below to clear the paper jam error orincase there is one somewhere.

Turn off the Printer. Remove the drum and toner from the front cover. Remove the toner from the drum. Look inside machine incase of possible paper jam. Open back cover and paper tray incase of jam. Close all doors and put toner and drum back in machine. Turn on the printer, and see if the error message is gone.

Step 1
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.
Step 2
Turn off the printer.
Step 3
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Step 4
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
Step 5
If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it.
Step 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.
Step 7
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though.
Step 8
Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
Step 9
If the printer paper jam message still appears, then there is still some paper in the printer. Inspect the paper path once again.

1. Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.

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.

Try unplugging it and opening every door possible and pulling every toner cylinder. Put the toner cartridges back in and close the doors and plug it in again and see if it works for you like it basically did for me.

I had the same error so I unplugged it and open every door where a paper jam could be. Pulled out every toner cylinder and put them back in. I wiped down where I accidentally spilled some toner (FYI Never pull out the front casing for all the toner without the printer remaining right side up.) I plugged it back in and then got a new error message - that it was out of magenta which I've been expecting for awhile. I replaced it and now it's good to go. Good luck.
