Question about HP Officejet Pro L7780 All-In-One InkJet Printer

2 Answers

My HP Officejet Pro L7780 faxes off & on. Motor is running w/in ADF, but the pick assembly does not grab paper

When paper is loaded to fax, ADF registers that a document is loaded. I dial the fax number, it dials and attempts to fax. Everything sounds like it is working, but the pick assembly will not grab the document.

There should be a textured seperator pad, if that's worn out, replace it. Also check the ADF rollers should not be smooth. You may need to just replaced the ADF maintenance kit. It should include the roller assembly and seperator pad.

SOURCE: The auto-document feeder on our HP L7780 OfficeJet

I put an elastic band around the black roller as it doesnt seem big enough and it works nearly every time now. Have done this with another L7780 Pro as well which fixed it completely on that one.

Lift the cover to the ADF (Automatic Document Feeder) and remove any paper debris from the rollers. Also, clean the rollers with a very damp cloth and a dab od dish washing detergent.

  2. Grasp the upper edge of the automatic document feeder (ADF) assembly and open it.
  3. Raise the roller assembly.
  4. Gently remove any jammed paper from the ADF.
  5. Lower the roller assembly.
  6. Close the ADF assembly.
  7. Plug the power cord back into the product.
  8. Press the Power button (c01346625.gif ) to turn the product on.
  9. Try the print job again.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

HP Office Jet 6110 All in One faxing


This document covers the basic fax functions of the HP Officejet 6100 series. The HP Officejet 6100 series can perform the following functions:
  • Send and receive paper faxes.
  • Send and receive color faxes. Color faxes can be sent only to color fax capable machines. If a color fax is sent to a black-and-white only fax machine, the HP Officejet sends the fax in black and white.
See Figure 1 below to identify the buttons in the Fax area of the front panel. Figure 1: Identifying the fax area of the front panel c00259777.gif 1- Turns Auto Answer on or off 2- Scrolls through speed-dial entries 3- Redials the most recently dialed number 4- Dials fax numbers, enters text, and specifies menu items. 5- Starts a fax 6- Changes the fax resolution 7- Dials one-touch speed-dial numbers Fax settings Most fax settings are configured during installation through the Fax Setup Wizard. These settings, and some additional options, can be accessed through the front panel menu (see Figure 2). Figure 2: Changing fax settings from the front panel menu

1. Menu: enters the menu system.

2. Right and left arrows: navigate the submenus and options.

3. Enter: selects a submenu or option.

4. Cancel: exits from the menu. c00259778.gif Sending a fax To ensure the best quality when sending faxes in color, use a color original instead of a color copy. Follow these steps to send a fax:
  1. Load the original. Load originals directly on the glass or in ADF. For multi-page faxes, you must use the automatic document feeder (ADF). Loading original on the glass Place the original, print-side down, on the front-right corner of the glass. Loading original on the glass c00259779.gif Loading original in the ADF Place the original, print-side up, in the ADF. Adjust the paper-width guide to fit the original. Loading original in the ADF c00259780.gif
  2. Enter the fax number using the keypad. Dial the number just as you would from a telephone (dialing 1 before an area code, etc.)
  3. Press Start Fax Black or Color.
  4. If there is no original in the ADF, the display will read, "Send from Glass? Press 1 for Yes or 2 for No"
    • Press 1 to scan the document from the glass.
    • Press 2 to load the document in the ADF. The display will read, Load original, then press Enter .
