Hi travlynn2,

1. The ADF
   unit is the grey paper tray located on the top of the scanner unit.
   Check the following points if it does not feed paper, or you receive an "ADF jam" error message:
   
   


2. Check the position of the ADF document guide:
   
   
   
   
   1. Lift up the ADF unit. Locate the document guide on the underside, as shown here:
      
      
   
   
   2. The document guide should be tucked in behind the grey plastic casing, but a paper jam can push it out of position. Figure 8 below shows the correct (1) and incorrect (2) positions:
      
      
   
   
   3. If your document guide looks like example (2)
      on the right, lift it out on the right-hand side. Tuck it in behind the
      grey section, so that it matches the example on the left (1).
      
   
   
   
   
   
   
   1. Close the scanner unit.
      
      
   
   
   2. If the printer is displaying "ADF Jam, press start to continue", press the B/W Start button to clear the error:
      
      
   
   
   3. Test the printer by scanning or faxing via the ADF unit.
      
   
   


3. Check the ADF edge guides:
   
   
   
   
   
   
   1. The adjustable paper tray edge guides must be set to the correct paper size for the paper you are loading. Otherwise, the paper may skew, misfeed and/or jam.
      
      
      
   
   
   2. Slide the edge guides to enclose the loaded
      paper (in the direction of the yellow arrows below), without causing it
      to bunch or crease. The paper should be aligned with the relevant paper size marker:
      
      Figure 9. The ADF edge guides.
      
   
   


4. Check the ADF unit feed rollers:
   
   
   
   
   1. Open the cover of the ADF by pulling up the grey lip, as shown below:
      
      
   
   
   2. Check thoroughly for fragments of paper and foreign objects. Take care not to tear any jammed paper when you remove it.
      
      
   
   
   3. Use the green gear (circled in yellow below) to turn the paper feed rollers and feed through jammed paper:
      
      
      
   
   
   4. Paper dust or foreign material on the rollers may cause paper to misfeed. Clean these parts with a damp, well-wrung cloth:
      
      
      
      
      1. The upper paper pickup rollers (circled in red, above top left). You can turn these by hand.
         
         
         
      
      
      2. The lower paper pickup rollers. These will rotate as you turn the green gear (circled in yellow above). See the inset for a close-up of the lower rollers.
         
      
      
   
   
   5. When complete, close all the covers.
      
      
   
   
   6. If the printer is displaying "ADF Jam, press start to continue", press the B/W Start button to clear the error:
      
      
   
   
   7. Test the printer by scanning or faxing via the ADF unit.
      
   
   
   


5. Check that the ADF unit sensors are not obstructed.
   
   
   
   
   
   
   1. Open the cover of the ADF unit.
      
      
      
   
   
   2. Look at Figure 12 below. Check the position of the black plastic parts (the actuators) circled in red.
      
      
      
   
   
   3. If the black plastic actuators do not stick out from the ADF cover, they may have been pushed out of position by a paper misfeed and be obscuring the ADF sensors. Tap the back of the ADF unit firmly to release the actuators.
      
      
   
   
   4. When complete, close all the covers. Check and test the printer as explained in Step 6.d.vi.
      

Hope this helps.

Thank you for using FixYa.

P error normally indicates that you need to add paper. If there is paper in the cassette and the paper is raising up to the roller then the paper feed rollers are most likely dirty. You can clean the rollers with a cloth and some rubbing alchol. Also make sure you dont have a small peice of paper or something in the paper path causing the paper not to feed. Also listen when you press the prnt/start button and see if you can hear the paper feed clutch turning on then the paper feed rollers turning.

Introduction When the all-in-one detects a paper jam, the display will read, " Paper jam: Press OK to continue ." The computer might display the following message: " There is a paper jam (or misfeed). Clear the jam and press the Enter, Resume or OK button on the HP PSC. " This document will assist in correcting paper feed problems such as paper jamming, print slanting, and multiple pages feeding into the all-in-one. Clearing paper jams CAUTION: All paper jams must be removed from the back of the all-in-one through the rear access door. Pulling the paper from the front of the unit rotates the paper feed roller in the wrong direction and can cause damage to the all-in-one.

1. Turn off the all-in-one and unplug the power cord.
2. Turn the all-in-one around so the back of the unit is facing out.
3. Open the rear access door:
   1. Locate the tab on the left side of the door and press it toward the right. The door will shift slightly to the right.
   2. As the door shifts to the right, pull the door out slightly to release.
   3. When the door is released, gently remove the door by sliding the door out and to the left.
   Figure 1: Removing the rear access door
4. Inspect the pressure rollers on the access door. They should be clean and rotate easily. If needed, clean the rollers with a soft lint-free cloth lightly moistened with water (distilled water preferred). If the rollers do not rotate easily, they may need to be replaced.
5. From the access door opening, gently remove the jammed paper.
6. Remove the paper stack from the paper supply tray. Discard any paper damaged or bent.
7. Re-stack the reload the paper into the paper supply tray. Push the stack into the tray until it stops.

Causes of recurring paper feed problems If paper feed problems occur repeatedly, one of the following might be the cause:

• Something is obstructing the paper or print cartridge path. Open the cover of the all-in-one and check for obstructions.
• The rear access door is unlocked or improperly seated. Follow the steps above to remove and re-seat the access door.
• The paper width guide is not positioned against the paper. Adjust the paper width guide against the edge of the paper.
• The paper is not supported. Paper should be flat and smooth with no folded, torn, or rough edges. Some glossy and/or coated papers, or reused paper (already printed on one side) can experience a higher incident of paper feed issues.
• The paper tray is not fully extended.
• The paper feed rollers need cleaning. Over time paper fibers and dust will stick to the rollers and should be removed. See instructions for cleaning the rollers below.

Paper jam message displays but no paper is jammed The print carriage might be jammed. Follow these steps to correct the problem:

1. With the power on, lift the print cartridge access door. The print carriage should move to the access area located on the right. If the print carriage stays all the way left, reset the unit by unplugging the then plugging in the power cord. If the carriage still does not move to the right, continue with the steps below.
2. Disconnect the power cord from the all-in-one.
3. Remove both print cartridges.
4. Push the print carriage slightly to the left and then to the right to verify that the print carriage is not jammed. If the print carriage will not move, check for obstructions under and around the carriage.
5. Close the print cartridge access door.
6. Plug in the power cord.
7. When the " Insert Print Cartridges " message displays, open the print cartridge access door and insert the print cartridges. Verify that both cartridges are seated correctly and lock into position.
8. If the error recurs, contact HP for assistance.

Envelopes The envelope flap can move with the grip of the rollers and cause paper feed problems. Use envelopes with a rectangular flap and/or tuck the flap inside the envelope when printing. The print is skewed or crooked A small amount of skewing is not unusual with printers. When there is too much skewing, the following steps can help reduce the amount.

1. Adjust the paper width guide to fit against the edges of the paper stack.
2. Verify that the rear access door is properly seated and locked into position.
3. Remove the rear access door and clean the paper feed rollers (see the instructions at the bottom of this document).

More than one sheet of paper feeds in at the same time Several paper caused problems can result in more than one page feeding into the unit. Check the list below:

• Reused paper (paper already printed on one side)
• Torn or folded paper
• Textured or coated paper
• Unsupported specialty paper

To determine if the paper is causing problems, try using clean, undamaged sheets of plain white 70 - 90 g/m2 (20 - 24 pound) inkjet paper, such as HP Multipurpose or Bright White paper. If this paper feeds correctly, the problem is probably with the other paper. Cleaning the paper feed rollers Over time dust and paper fibers will accumulate on the paper feed rollers. This can cause paper feed problems. Follow the steps below to clean the rollers: Figure 3: Paper feed rollers

1. Turn off the all-in-one and unplug the power cord.
2. Remove the rear access door (as describe above in this document).
3. Clean each roller using a clean lint-free cloth lightly moistened with water (distilled water preferred). Rotate the rollers to clean the entire surface.
4. Verify that the paper feed rollers on the rear access door are clean and rotate easily.
5. Re-seat the rear access door.
6. Plug in the power cord and turn on the all-in-one.

Clearing paper jams
Paper jams can be real or false. The unit may report a paper jam even when there is no jammed paper. The solution to a real paper jam or a false paper jam is the same.
CAUTION:
Jammed paper must be removed using the rear access door with the power cord disconnected to avoid mechanical damage. Do not remove jammed paper from the front of the unit.

1. Turn off the HP product and turn it around so the back of the unit faces you.
2. Disconnect the power cord from the back of the all-in-one. The power cord must be disconnected to allow the paper feed rollers to turn freely.
3. Locate and open the rear access door by pressing in on the left side tab and then pulling the door toward you.

Figure 2: Removing the rear access door

1. Inspect the pressure rollers on the rear access door and verify that they are clean and turn freely. Clean the rollers if needed with a soft towel lightly moistened with water. If the rollers do not turn freely, replace the rear access door. Click How to Buy on this page to order replacement parts.
2. From the rear access door opening, remove the jammed paper.
3. Remove the remaining paper from the paper supply tray. Discard any paper that is damaged or crumpled and then re-stack and reload the paper into the paper supply tray.
4. Reinstall the rear access door.
5. Reconnect the power cord to the unit and turn the unit on.

Preventing paper jams
The following information will help prevent paper jams from occurring:

• Never use paper that is torn or wrinkled.
• If you are having problems using paper that has already been printed on once (recycling), replace it with new paper.
• Remove and then reinstall the rear access door. Verify that the access door is fully locked in place. The paper can skew if the rear access door is not locked.
• Every six months to one year, clean the paper feed rollers with a rag lightly moistened with water. Over time the paper feed rollers accumulate dust and do not function as well as they once did.
• When printing envelopes, tuck the flap into the envelope and crease the folds before printing.

Clean The Paper Feed Rollers Using The Unit's Operation Panel If the paper feed roller is dirty, paper is not fed properly because the paper feed roller slips. Cleaning the paper feed roller could resolve the paper feeding problem. Please follow the instructions below to clean the Paper Feed Rollers directly from the unit.
