Lazer not scanner

Use a water dampened cloth to clean the pickup roller. They get residue on them over time that causes them to not grip the surface of the paper when feeding.

to fix the problem you have to press the plate that the paper sits on down until it clicks into place once you do that it should work fine.

Printing photos from the back feed? Using special photo paper? Try cleaning the paper rollers that feed the paper. They get slick.

The printer hardware should even this out when printing. You should also ensure the paper meets the automatic feeder requirements of the printer.
If printing is skewed, feeding multiple pages or jamming, please follow these instructions (use a regular letter size paper to test after doing the steps given below):
Please check to ensure there is nothing obstructing the paper feed mechanism down inside the printer where it is not easily seen. If there is nothing obvious, unplug the printer and remove the paper. Open the front cover and look above the steel rod. You should see a conveyor belt with rubber teeth on it, like a fan belt. Take the bottom part of that belt and move it gently to the left. The cartridges should come out with it. Make sure the cartridges can move fully from one side of the printer to the other. Check also the output rollers on the bottom of the printer for any blockage. If it is jamming under the carrier assembly, you may be able to fix it using the manual feed slot. Turn the printer off. Next take a #10 envelope and feed it through the left side of the paper feed slot (The manual paper feed slot is preferred, but the automatic feed will do if there is no manual paper feed for this printer) until it comes completely through the printer to the back of the exit rollers. Move it up and down and slowly move it over to the right side. If something is stuck under the black guide plate this may work it loose or you may have to feed the envelope through the front rollers and push your way backward (please be careful here).
Next, take a damp warm cloth and clean the rubber rollers in the automatic sheet feeder. Dust may be coating the rollers there and as they become less tacky, they cannot feed paper correctly.
Finally, turn the printer upside down and carefully shake it for 10 to 20 seconds to see if something falls out of the paper feed path. Then plug the printer back up, take your paper out and replace it with a fresh, small stack (about 5 pages) of paper. Quickly bend the stack in an 'S' shape a few times to separate pages. Make sure it is lined up on the right side of the paper feed and the paper guide on the left is snug on the left side of the paper. Then try to form feed again. If that works, then try to print again.

sounds like something jamed in the rollers like a pin etc

THERE MAYBE PAPER STILL IN THE MACHINE, YOU MAY HAVE TO REMOVE AS MUCH AS THE CASE PARTS TO SEE IF THERE ARE ANY PAPER INSIDE THE MACHINE, TAKE SOME ALCOHOL AND CLEAN THE ROLLER, FEEDER AND ANY OTHER ROLLER YOU CAN GET TO YOU MAY EVEN WANT TO USE A Q-TIP TO GET TO THE ROOLERS NOT REATCHABLE BY HAND. REMOVE PRINT CARTIGES MAKE SURE THEY ARE CLEAN OF DIRTS,
TRY DOING PRINTER ALIENEMENT OR PRINT TEST FIRST AFTER CLEANING.

Hi,
Sounds like the feed rollers need cleaning.
Clean the feed rollers, lint free cloth,bottled water.
wait for them to properly dry

Revolve the feed roller bar as you clean them, to clean the feed rollers all the way round, remove all particles from them.

Check you ADF grips are set correctly, if not you will get mis-fed sheets. check the tray is sat properly too or mis-feeds.

Check paper size is correct in print properties too.
Should be good then
Try print.

Regards
Richard.

Best results will be if the paper you are using is designed for use in this machine and you print with the driver knowing paper type and using a direct flat paper path

Use The bypass tray (and you can also use face up delivery tray ) and make sure you tell printer what paper type it is using ie control panel, printers, preferences, paper type set to photo/gloosy or even card stock if it is thick.

Ensure feed rollers are clean, and paper is good quality

SEPARATION ROLLER MAY NOT INGAGE CAUSING THE PAPER NOT TO FEED TO THE FEED ROLLERS THE PAPER DOES NT ADVANCETO THE REGISTION ROLLER THAT SET THE PAPER FO COPY CHECK TO SEE IF THEY ARE CLEAN OR WORN

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)
