Most 13.20 error messages have been associated with exit sensors in the optional paper trays and with pre-feed sensor PS102, although this message can be displayed with a failure of any of the paper jam sensors. Using the Manual Sensor Test in diagnostics is the most useful tool in troubleshooting 13.20 errors.
Hope you are well, usually that error message stands for paper jam inside the printer, please check the rear door, remove the tray 2 and check for paper stuck.
13 – Paper Jam

If this code appears you have a paper jam, newer models of HP printers will tell you where the jam is located so you can just follow the instructions on the screen to resolve the error code.

13.5 PAPER JAM CHECK REAR DOOR Paper-delay jam at fuser. 1. Check the transfer roller and small media belt to ensure they are operating and can feed print media. 2.
The above listed printers may produce a 13.20. 00 `jam in right front door` error code. While there may be no paper visible, this is usually caused by a dislodged tray 1 pickup roller cover which disrupts proper positioning of the duplex refeed sensor flag.
Very often a 13.1 Paper Jam Message will appear, instructing the user to check Tray 2 or to check under the toner cartridge. Upon thoroughly checking the printer there is no paper jam to be found anywhere.
A 13. FF. FF error is related to jams in the paper path. These errors indicate that the product powered up with a jam.
When a 31.13. 13 error appears on the control panel, it indicates that there is a jam in the document feeder because the feeder cover is open. Open then close the document feeder cover. If issue remains, open the document feeder cover.
Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the device to initialize. 2. If a surge protector is being used, remove it. Plug the device directly into the wall socket.
Recommended action. Turn the printer off, wait 15 seconds and turn the printer back on (using the power switch located on the back of the printer). The error code should not appear again.
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.
If your printer is turned on, disconnect the power cord from the printer. Keep the power plug unplugged for 60 seconds, reconnect the power cord to the wall, and turn on the printer. If the error persists, remove the cartridge from the printer, clean the cartridge contacts with a cloth, and reinstall the cartridges.
It means the top of the paper isn`t being detected arriving at the fuser delivery sensor. This could either be the pre-feed sensor (which starts the timing), the top of page sensor or the fuser delivery sensor failing to trigger.
Cause: Paper is jammed inside the printer. Remedy: Remove the jammed paper and set the paper cassette and covers to the original position.
How to Resolve the Invalid Amount Code. Resolving error code 13 alerts is quite simple. The user will need to carefully scan through all field inputs and verify that the characters or symbols they put in are appropriate for each field. It`s also important to make sure there aren`t any negatives or incorrect symbols.
The error is 13.02. 00 indicating it isn`t reaching the top cover sensor. The paper is getting stuck at the fuser, and the fuser is leaving a very noticeable indentation mark.
The event code: 13. B9. FF indicates that the printer believes there is a jam at the fuser output sensor, at power on. That means that printer has been power cycled, and the printer detects paper under the fuser output sensor while checking during the boot process.
Recommended action. Turn the printer off, wait 15 seconds and turn the printer back on (using the power switch located on the back of the printer). The error code should not appear again.
A 13. FF. FF error is related to jams in the paper path. These errors indicate that the product powered up with a jam.

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.
