Try cleaning your feed rollers...
There are two types of rollers in printers: hard plastic and rubber. Plastic rollers can be cleaned with alcohol (isopropyl). Rubber rollers can be cleaned with a rubber roller cleaner and restorer like the one in the link (you can find other brands, but make sure its for rubber).

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.

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.

SEGGUSTION #2 cleaning 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.

If these suggestions don't fix the problem feel free to write back to me. Try to be a little more specific i.e does paper feed properly, error message shows with paper/without paper or both, do any of the lights flash when this happens, have you tried diiferent paper sizes ot types. Have you taken it apart to check for any obstructions?

That is the problem, machine will show printer jam if paper feed rollers fail to pick up paper when requested, your machine sounds like it needs new paper feed roller or you can clean the paper feed roller with a slightly! damp cloth.

If no jam light shows when power is turn on and machine comes to ready and then you send a job to printer and it then shows jam then it is the feed roller or sometimes the feed clutch

If on the other hand it always show jam then there is or a switch is stuck.
