You need the pick up rollers replaced. Call your service centre to replace pick rollers as these are feeding the pages crocked

Hi,
Remove the jammed paper. Unplug the printer from the mains and PC. Inspect the rollers, etc for tiny paper piece(s) that may be stuck, or other debris. Try to clean rollers and make sure they are dry.
Keep printer unplugged for about 2 minutes and replug and try a test print.
Also make sure that you have waited long enough for the printer to heat up before giving a print job.
Finally, it could be an issue with the paper sensor. If this is the case, you will probably have to take the printer in for servicing..

I had the same problem and just talked with HP technician Neeta and she showed me how to fix it. It's a bit convoluted. In essence you have to clear the print spooler. Here is what she told me.

First you have to be clear that there really ISN'T a paper jam by printing a test message this back door way.

Neeta : The USB cable should be disconnected. Neeta: To print a self-test page, press and hold the Power button. Raise and lower the printer cover four times. Release the Power button, and the self-test page prints

If the sel-test page prints, this means you truly do not have a paper jam. Next, clear the print spooler

Neeta : The USB cable should be disconnected.Neeta : Now click on start->RUN.Neeta : Then type "services.msc".Neeta : Then it will open the services window.Neeta : Now please look for the option "print spooler. Neeta : Okay, now , please right click on the option "print spooler" and click on stop then click on start, 3 times.

Hi,



. Switch off the printer and disconnect the power supply. Allow any residual charge inside the all-in-one printer to dissipate before putting your hands or any metal tools inside the chassis.

2. Pin down the exact location of the jam. The 3 hot spots for a jam are before a sheet completely leaves the paper tray, anywhere between the feed tray and print carriage or between the print carriage and output tray.

3. Take off the front paper tray if the sheet jammed while still in the front area of the printer. If here, you should be able to see most of the paper.

4. Pull the sheet with both hands and steady pressure. Do not tug as you might rip the paper, leaving a piece deeper inside the machine.

5. Open the back panel to reach paper jammed between the feed-tray area and print carriage. Carefully remove the jammed paper.

6. Use the carriage access door to get at a jam further inside the printer. You may need to remove the print carriage to get to the jam.

7. Replace all parts and return any access panels to their closed and locked positions. Plug your printer back in and flip the power switch.

Run a half test. Start printing a few pages, as it prints open the cover, remove the toner and look down at the paper. Does it have lines on the right side? If yes - replace the toner cartridge.

Try lowering the toner density using the printing software or the printer menu.

Close all the running programs/applications on your computer.

1. Click Start --All programs - HP - HP Director/Solution center.

2. In Hp Director/Solution center Click Start - Settings - Print Settings - Printer Settings

3. Click on the Features tab. Set the Paper Type to Plain paper and Paper Size appropriately.

4. Click Ok. Close HP Director/Solution center.

Open the application and try printing.

Thank you.
