Question about HP LaserJet 2550Ln Printer

1 Answer

Paper jam with card stock paper

My HP Laserjet 2550 LN printer is now 4 years old and I have printed 8x10 photos on cardstock until about 4-6 months ago. I would open the back, and the printed sheets would roll out the back.

Now, the printer jams if I open the back but it still pulls paper through and rolls it out the top.

Also the printer jams with back open or closed when I try to print on a full 8 1/2 x 11 sheet of card stock. However, I can cut it in half and print up to 5x7's by letting the paper roll through and out the top (curling it slightly in the process which I do not like).

I had read some time ago that the "teeth" or whatever grabs the paper could wear down and that there was something to buy that would solve the problem. That sounded like what is happening with my printer because the papers are not pulled through consistently and the top margins of a series of sheets can vary. Sometimes I hear a grinding sound and when that happens the print will be way off - maybe an inch or more too low down on the paper - or the printer simply jams.

The HP tech said I am using too heavy a paper and could provide no help! He had never heard of something to help pull the paper through. (He was not from the U.S. and could not offer suggestions that American techs had done for me in the past.) I KNOW I am using a heavier paper than the printer's specs approve but I have been doing it for years and want to continue to do so even if it means buying a replacement part. My photo restoration customers prefer prints made from my computer on card stock rather than the glossy and semi-glossy prints made at local photo printing businesses.

My imaging drum is now down to 14% but it was about 50% when the problem began and I called HP tech help. He said the problem is not the imaging drum. I am investigating purchasing an Image Drum Reset Chip if the drum is not causing my jam problems with card stock.

Why is my hp 5610v not printing on cardstock?


Are you print through manual bypass? If not try doing it that way. Card stock is very thick and by using manual bypass it doesn't require as many turns for the card stock.

I wish to use my HP Photosmart C8180 to print heavy weight cardstock... is there a setting that I can select to do this?


Step Three: Check the paper type Verify that only recommended paper is being used for printing. The recommended paper types and weights for most HP printers include:
  • Plain paper, 20 to 24 lb (75 to 90 gsm)
  • Legal size paper, 20 to 24 lb (75 to 90 gsm)
  • Card stock, up to a maximum of 110 lb (200 gsm)
  • Envelopes, 20 to 24 lb (75 to 90 gsm)
  • Photo paper, 145 lb (236 gsm)
NOTE: Supported paper weights and types vary by product. Check the Specifications sheet for your product for more information.

If you use card stock up to a maximum of 110lb then there should be no special mode to enter to print on this type of paper. Photo paper weighs in at 145 lb maximum which is heavier and can be printed on without selecting any special 'mode.'

Good luck on printing on heavy card stock.

HP Photosmart 7550 - Full Page Photo Printing Jams at end


Normal 0 I suggest you get a sheet of Card Stock (Heavy paper) and place it in the feed way. Then press the print button applying a slight amount of pressure on the Card Stock so it will feed through the printer. The reason for this, is in some cases I have been able to clear the paper track of debris that was deposited there over time.
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud

Paper keeps jamming


To print card stock you must us the manual slot in the front of the printer and feed one at a time. Also open the back flap door so the card stock can exit out the back instead of trying to bend around for the try. That will give you the staight paper path that your thick stock needs.

Printing Business Cards on Cardstock


It could be.

Part of the problem with that machine is that it has to bend the paper to get to the inkjets. If its too think it will stop running.

We use this Avery stock for printing business cards that might be a little thinner cardstock. I would look for some recommended for ink jet printers.

Can't Print on Card


I had the same problem with my 3 year old HP Officejet 5610. Feeding heavy paper or white card stock would result in a paper jam. The card stock would start to feed, but then stop half way. The pinch rollers seemed to spin without advancing the paper, even if the paper was fed one sheet at a time.

Solution: Clean the rubber pinch rollers with isopropyl rubbing alcohol. Partial disassembly/reassembly required.

To access the rollers, remove the scanner plate:
1. Disconnect power, USB, and phone cables.
2. Open up the scanner sheet feeder by tilting it left.
3. Unlatch the scanner scanner feeder so that it opens completely vertical. Latch is on front hinge only.
4. Remove the 4 corner hex screws on the scanner plate. Remove the 2 hex screws on the sheet feeder. (I used a small flat blade screw driver in the hex heads)
4. Lift the plate and sheet feeder away from printer box. Disconnect the 2 flat cable wires from the circuit board.
5. Scrub rubber pinch rollers with alcohol on a swab. Dry thoughly.
6. Reassemble. (NOTE: This is a good time to clean the underside of the glass plate and the scanner head)
