79 Error

Turn off then on

The device has experienced an internal

firmware error.

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.

If you have recently installed a memory

DIMM in the device, turn off the device,

remove the memory DIMM, reinstall the

DIMM to verify that it is seated properly,

and then turn on the device.

If a surge protector is being used, remove

it. Plug the device directly into the wall

socket. Use the power switch to turn the

device on.

If the error persists, upgrade the firmware.

See Updating or recovering the firmware

code.

If the error persists, replace the formatter.

The fuser is the heating unit near the paper exit, and that error means the lamp is burned out, the overtemp sensor is out, or the thermistor in the fuser is bad. About all you can do is replace the fuser. www.precisionroller.com will have a new fuser for you.

The error your having caused by the scanner assembly in the Auto Doc Feeder. The part is not real difficult to replace however it is not cheap. Here's the part number: Q3948-60191.

The part is available through HP online at http://partsurfer.hp.com for $130.76 plus shipping. It is also available (probably a little cheaper) from Seattle Platen, Dale - 1-800-221-2388.

We have been sucessful a couple times in disassembling the lower (scanning) section of the Auto Doc Feeder and thoroughly cleaning all mirrors and lenses. It's about 1 in 8 that will clear up the issue. Replacement is 100% cure.

Here's a free copy of the HP 2820/2840 service manual that will help you in the disassembly.

Hope that helps solve your printer issues. :)
