Delivery fan (fan #4). These are the fans that are at the top of the printer just over the top of the fuser. They might just be dirty or they might be defective.

If you have already removed the paper from the output bin, check the delivery flaps to make sure they move freely. If they do, remove the top and make sure the sensor flag isn't broken and that the sensor is connected and undamaged. If it is connected and undamaged, check connector J213 on the engine controller is seated correctly. If it is, you probably need to replace the output bin sensor. See attached video

Try Engine test:
turn on device open tray 1 and load paper (1 is the manual feeder)
when you open tray 1 there's an engine-test switch, found it and press it

Engine error are also cause too much resistance from toner, fusor or gears. Remove toner and check that it roll with your fingers on gears, and do same with fusor (could be very hot warning - should be hard move it but not too much) and with printer off and fusor removed check if you can move any gear manually (this can be harder but will help you determine if it's board error or resistance cause a gear problem).
Any previous error happened with the printer can help to diagnose (jams, power off while printing...)

Before starting, note down the IP address if its network printer..
1. Turn the product off.
2. Turn the product on. When the memory count begins, press and hold the OK button. Continue holding down the OK button until all three product control-panel lights flash once and then remain on. This might take up to 10 seconds.
3. After the message SELECT LANGUAGE appears on the display, press the button or the button until COLD RESET is highlighted.
4. Press the OK button. The product performs a cold reset and then continues its power-on sequence.
5.Chk & set I/O settings..if required..

This could be a fuser issue or a paper exit sensor issue. Please take out the fuser and check the pressure roller. Be careful, the fuser is extremely hot.

79 is an firmware error. Try to update the firmware. You can find the file on HP website, on the Drivers and Support section. There must be also the procedure to execute the update.

hey,
Its a scanner error - often these can be fixed.
The poster above forgot you have 2 scanners. Your error refers to the laser/scanner which is the unit that writes the information to the drum of the toner cartridge for printing. A bit different and a little harder to get to. The laser/scanner is the black box that sits above the toner cartridge on the frame and you have to remove the scanner/adf unit to get to it. The service manual has directions. When you remove the laser/scanner it you open the black box carefully you will see a chrome motor wheel towards the back that spins. Usually the shaft of that motor has become to tight with debris or other material and can not get up to speed. Sometimes there is a small clip that secures the motor in place and other times you can just lift up the chrome piece and it comes out. In either case you need to place one tiny drop of synthetic oil down the shaft of that motor, put the chrome piece back on, spin it a few times to make sure it is smooth and then put everything back together. It should then work. If not then the laser/scanner needs to be replaced. The first thing you will want to do is check the flat ribbon cable on the left side of the printer that plugs into the board. It will be the thinner cable.
This scanner error - often these can be fixed.

Most commonly this type of jam is paper jammed somewhere between the paper tray and the cartridge. As you did not state model I cannot be more specific than that.

HP LaserJet... | Answered on May 26, 2015


This can normally be fixed by upgrading your print driver to the newest version. You can find print drivers at this link http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=412131&swLangOid=8&swEnvOid=54
Good luck
