The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.

I found the following: Error 50 means that the heating of the fuser unit is no longer working. This is usually a burnt-out heating lamp,or a defective thermal fuse.

(From: Tom Dunn ([email protected]).) Error code 51 indicates loss of laser beam for over 2 seconds. Check -5 V, also make sure there is no interlock mechanism damage, and +5 V at J451-1 on Laser Drive PCA. You may need new laser unit.

If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.

1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.

The printer stops feeding pages, the control panel displays an alternating E and 4, and the Error icon , Paper Error icon , and Resume light blink. This indicates that paper might be jammed inside the printer. Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper.

HP Printer Error E4 means that the FINE cartridge in your printer device is not installed appropriately. To move out the cartridges, you will require to push the output tray back in before opening the cover.

A 49 error typically occurs when the printer attempts to perform an action that the firmware is not capable of performing or might not be designed to handle, for example: Printing files that include unsupported printer commands.

57 is a fan error, check are the fans are rotating, and make sure the printer power is plugged directly into the wall socket. 57 is a fan error, check are the fans are rotating, and make sure the printer power is plugged directly into the wall socket.

A Printer Failure. There is a problem with the printer or ink system. Turn printer off, then on. If problem persists, contact HP. error message displays on the printer control panel, and the printer does not print.

Possible causes for this error include: Swing arms are not engaged. Lift motor or clutch failure. Dirty or defective encoder disk/sensor.

For anyone else who finds this page when tracking down this error, Error 79.8109 is simply the result of using the wrong printer driver (i.e. the HP Universal PCL6 driver, as provided under Windows 8 and 10). This driver does not work correctly with this printer. In general this error isn`t a formatter problem.

HP Laserjet 6MP wont feed paper

ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking

ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.
