HP LaserJet 4350 Printer - Answered Questions & Fixed issues
49.2F80
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
Left corner is folded down on page
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.
Replace the dc controller PCA
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.
Error 50.40
50.4 is a problem with the fuser, likely a bad heating element.
Paper jam in tray 2 but there is nothing jammed.
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....
Hp laser jet 3005 printer clearing paper path error
I would pull out the paper tray, and clean the underside roller. First try to clean it without moving the clips. Use a cotton cloth or lint free cloth and alcohol. Get as much paper dust off as you can. This might help you out.
49.1643 Service error
Go to hp webite and download resent firmware and that should fix it. Just for kicks, change the toner cartridge out. I saw one causing 49 errors because the gears were locked up, causing gears no to turn. Good luck
