Normally it is fro corrupt data or bad cables.

49.xxxx error explain.

A critical firmware error has occurred that
caused the processor on the formatter to
abort the operation.
This type of error can be caused by invalid
print commands, corrupt data, or invalid
operations.
In some instances, electrical noise in the
cable can corrupt data during transmission
to the printer. Other causes include poorquality
parallel cables, poor connections, or
specific software programs.
Sometimes, the formatter itself is at fault,
which is usually indicated by a 79 Service error

Sounds like an issue with the feed rollers. The roller on the left side might be hung up and is causing the corner to fold over when the paper is pulled through. I would try checking the feed rollers in either the actual tray or the back of the printer. Another thing to check is the other tray (the manual one). Does the paper fold? this should help you narrow down where the problem lies.

Remove the right side cover, top cover, remove the formatter board and you will see the controller board. Don't have to label the wires, each one goes into its own connector.

Try replacing the cartridge first and then the fuser

Typical of this machine. You have worn out feed rollers in tray 2. There are three of them, two in the top of the machine after removing the tray and one in the tray itself

Perhaps just a bit of dust or a scrap or paper is fooling around in or close by the sensor. That is one of the reasons maintenance always use a vacuum cleaner.

1st thing to do is upgrade the firmware. Go to hp.com and look for the software and drivers. Drill down to the firmware and read the instructions.

50.4 is a problem with the fuser, likely a bad heating element.

you'll need to file the actual print "button" if you print "screen" this will happen all the time

are you using the manual feed tray? If not try that as a solution.

I was able to fix it by taking off the top of the printer. This involved taking off 4 screws on the top of the printer. I then had to disconnect the wires going to the control panel by unhooking them from the right side. I then located a thin rectangular box which I'm assuming houses the laser. I removed this with 4 more screws and turned it over. There was a little metal flap that I moved back and below was the mirror the lasers shoot on before going onto the toner.

In the same spot where I was having fading, I noticed a lot of toner on the mirror, so I cleaned it of, put it back together, and the fading was gone.

This was after I tried a new toner and maintenance kit.

Hope this helps

Paper not being picked up, does it have a 3rd tray, take all paper out of tray 2 and see if you can get paper to feed from 3. Also make sure the lever on the cassette tray is in the normal position and check the menu in the settings. Some times the front registration area above the cassettes goes bad, not very common but does happen...place som toner on the wheels in tray two and try to print, see if the toner rubs onto the paper, if it does means wheels are turning, if not wheels are not turning....
