The flag located right of the pick-up roller has a fixed position. If the flag becomes stuck or broken, it will produce a 60.02 tray lift error or a “LOAD PAPER” message. If this flag is broken or if the sensor has failed, the RM2-6368 paper feed guide will need to be replaced.

Usually, for 59. F0, it is recommended to try resetting the toner and the fuser assembly. Reset the printer using the power switch, turn off the printer for a few minutes. Turn on the printer and wait for the HP colour jet printer to revitalise.

Apparently, a bad toner cartridge can cause error 59.00. 30, but replacing the toner combined with: removing the fuser and putting some oil on the axis at each end (and turning the gear several revolutions), cleaning the paper path and rollers solved the problem.

Turn off the HP printer and unplug it from the power source. Also, shut down your computer and unplug any external devices. Wait for a few minutes and then plug in the printer and turn it back on. Finally, turn on your computer and check if the error state has been resolved.

Error Code 51.1 says Printer Error No Kidding.lol

ANSWER : Sometimes turning off and on will allow you to print a few pages. The error is a beam detect error. The only real fix is to replace the laser scanner unit. Could be a loose connector on the scanner or DC controller from the scanner. That’s unlikely. You could try the only other free fix which is to open the scanner assy. and clean all the mirrors inside. The dust could obstruct the laser beam enough to cause the detect error.
