PAPER JAM WON'T PRINT - Brother HL-2170W Laser Printer

The error code 50 indicates a paper jam condition. Whether there's actually still paper jammed or not, it's sensors are still indicating a jam. Check again for a bit of paper, or there may be a faulty sensor.

I use to have an HP All-In-One Laser Jet printer that, for reasons unknown to me, wouldn't print after clearing a paper jam until I replaced the ink cartridge.

Hi
Turn it off and on.
Check through the paper paths and clear any paper jam.
Try disconnecting the printer.
Leave it for like 2 hours and then connect it again.

Hi, Try pulling out the plug for 1 hour and then try again. Pulling the plug may reset the printer.
Good luck.

you need to remove the black plastic on the back wipe the rollers that feed the paper put it back together plug it back in switch on and it should work some times u get a small corner of paper stuck so it tells the machine that u have a papaer jam

The lights continually flashing indicate a paper jam or the printer being out of ink. Check/clear any paper jam and verify the ink cartidge is set correctly.

open the printer tray and remove the paper jam

I had the same problem...after trying everything suggested on the forum. I had enough and decided to disassemble the printer. I removed the CAD and disconnected the wires and it solved the problem. No more paper jam error code on the screen. This probably includes that the CAD won't work anymore but I never used this anyway. So now I can print and scan like I used to.

Paper jam without a paper jam

This is a widely known problem with this printer and means the formatter board needs to be replaced. Save yourself the cost and headache of repairing and move on. The problem initially began as a random situation where I would have to turn the printer off and back on to get it to print.This eventually progressed to the problem you all are reporting which is the amber toner and jam lights on. I replaced the formatter board on mine and after one month the problem returned with the new formatter board needing replaced as well.

Of course, HP acts as if they've never heard of the problem. This company's integrity and quality has gone from number 1 to dead last.
