Unable to print anything because of continual paper jams. I can clear them with difficulty, from the rear of the printer. This first happened after I printed a colour picture and immediately tried to copy onto the other side. Both cartridges are recently replaced and were printing well.

Try using regular paper on unit as specified by Samsung. If that does not resolve the issue then the hassle lies with the paper feed mechanism. Often a good cleaning of all the rollers in the path can take care of the issue.

Clear the paper jam. If the problem still continues after clearing the paper jam, try to clean the encoder strip behind the printer head

We recommend that you clear the entire paper path when a paper jam occurs.

To clear a paper jam:

1 If you are feeding paper from a tray, remove the tray, and then remove any jams.

2 Open the front cover and remove the print cartridge assembly.

NOTE: Do not leave the print cartridge assembly exposed to direct light for an Extended period of time. Extended light exposure can cause print quality problems.

3 Remove any jams in the area behind the print cartridge assembly.

4 Lift the flap at the front of the printer and remove any jams beneath the flap.

5 Open the rear exit and remove any jams.

6 After you have cleared the jams, reinstall the print cartridge assembly, make sure all printer covers and trays are closed, and then press Continue button to resume printing.

NOTE: The printer reprints the pages that caused the paper jam.

Regular paper, envelopes, or specialty media may get stuck or jammed in the printer. Follow the instructions below to find and remove jammed paper (or other media) from the printer. If the HP All-in-One has a paper jam, first check the rear door. If the jammed paper is not in the rear rollers, check the front door.

Step one: Check for and remove any paper stuck in the paper In tray

1. Remove all loose paper from the paper In tray.
2. Press the RESUME button.
   
   • If the paper jam is cleared, skip to Step Four
     
   • If the paper is still jammed, continue on to the next step below.

If more than one sheet is stuck in the printer, remove the paper, one sheet at a time by taking hold of a sheet in the middle of the stack and, with both hands and firm, even pressure, pull the sheet towards you. Usually, removing one or two sheets from the middle of the stack will release the pressure and the rest of the stack can be removed.

After removing the paper, check to make sure no scraps of paper are stuck in the printer.

• If the paper jam is cleared, skip to Step Four.
• If the paper is still jammed, continue on to the next section.

Step four: Verify the print cartridge carriage can move freely

2. Check to see if the print cartridge carriage can move freely from one side of the printer to the other. If the carriage is to the right and out of plain view, skip to Step Five. Do not try to force it to move if it is hung up on something. [img src="http://h10025.www1.hp.com/ewfrf-JAVA/Image/common/note.png" alt="">
   NOTE:Be careful not to force the print cartridge carriage. If the carriage is stuck, forcing it to move will damage the printer.
   
   • If the carriage does not move, continue with the next step below.

Remove the print cartridges.

Step five: Reload and test the printer

Once the jammed paper is removed, verify that the printer is still functioning properly.

1. Reload the printer with plain paper.
2. Perform a self-test by pressing and holding the Resume button until the printer starts printing. A test page should print.

NOTE:Do not put more than 35 sheets of plain paper in the document feeder tray.

Gently move the print cartridge to the far right of the printer.

Remove the paper from the paper In tray, but do not remove the drawer.

Remove the rear access door.

With your fingers, rotate the rollers "up" three full rotations.

Push the rear access door back into the printer until it snaps firmly into place.

Replace the print cartridges.

Plug the power cable into the HP All-in-One.

Turn the power on.

Step six: Service the printer

Perform all the steps mentioned above. If the problem continues, service the printer.
Cause Paper jams can be caused by several factors. Follow these guidelines to prevent further paper jams.

• Insert paper into the paper tray only until it meets resistance. Do not push it farther in.
• Make sure that the paper is flat in the paper tray and that the guide is adjusted to the width of the paper.
• Do not add paper while the product is printing.
• Remove printed pages frequently.
• Do not use paper that is too thin, too slick, or that stretches.
• Do not use torn or creased paper. Used paper might cause jams.
• Make sure that the rear access door is securely fastened.
