Where can you find the feed rollers for the HP LJ 4250's enveoper feeder. The part number for the feeder is Q2438-67902.

To initialize NVRAM, turn the printer power off. Remove any installed accessories (for example, a stapler/stacker). Turn the printer power on, and then hold down (SELECT button) when the memory count begins. Continue holding down until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds. Press (UP ARROW button). Press the PAUSE/RESUME button (LJ 4200/4300) or the MENU button (LJ 4250/4350). The display should show SKIP DISK LOAD. Press (UP ARROW button) until NVRAM INIT is highlighted. Press (SELECT button) the printer initializes NVRAM and then continues its power-on sequence.

Yes, it is possible to be the problem. Most of the time you would replace the whole fixing unit, it could also be the paper feed rollers in the paper tray or the manual feed tray. Good Luck

There is still paper stuck in the printer. try lifting the printer off of tray 2 to inspect it or here it is straight from the service manual...

Hello Steve !
The only way scanning Legal documents on this HP LJ 3030 willbe using the ADF ( Automatic Document Feeder) since the size of the flatbed its only for letter.

So, after placing the document on the automatic document feeder theres a few setting you will need to change on the printer.

Number 1 : Go to Main Menu on the printer and look for System Setup, under system set up look for Paper setup,hit ok and now look for "Def. Paper Size" and set it to "Legal"

Number 2 : you should have a button on the printer control panel (Physical printer) that says " Reduce / Enlarge" , hit it and make sure the one selected is "original=100%"

Now just hit "Start Copy" and it print LEGAL ! it worked for me

Hope this help !

It is a problem with the drive train. It is not finishing the feed process. Or it could be the toner. Try replacing the cartridge and see if that helps.

Try putting Isopropyl alcohol on the feed rollers. These rollers become hard and smooth with time and cause all sorts of paper feed problems. You can find isopropyl alcohol at any drug store(it is rubbing alcohol).

are the feeder rollers moving? If so, the paper feeder rollers need to be cleaned.

You need a new TRANSFER ROLLER, it's the spongy roller under the drum.

I got to HP tech support, and they tell me that the envelope feeder is intended only for a few standard envelope sizes. If we're trying to use a different sized envelope, as in this case, it must be fed manually, and the feeder bin will not work. So that answers that. Thanks for the help, though.
