SOURCE: False Paper Jam Error
Make sure the paper tray guides are set against the paper more likely to be the back guide not pushing the paper to the front of the tray. If you have the guides set correctly then place one sheet of paper in the tray and blot some methylated spirits on the leading edge along the page width and close the tray and try printing something.
You will have a jam repeat process 3 or 4 times then open tray and remove paper. Where you soaked the spirits into the paper there should be a grubby mark where the feed roller has rubbed and cleaned. Wipe the tray dry and put fresh paper in then hopefully you will now be able to print. If you cannot then the likely thing is that the paper feed pickup spindle is broken and will need replacing.
Hope this helps you and please rate me

. Switch off the printer and disconnect the power supply. Allow any residual charge inside the all-in-one printer to dissipate before putting your hands or any metal tools inside the chassis.
2. Pin down the exact location of the jam. The 3 hot spots for a jam are before a sheet completely leaves the paper tray, anywhere between the feed tray and print carriage or between the print carriage and output tray.
3. Take off the front paper tray if the sheet jammed while still in the front area of the printer. If here, you should be able to see most of the paper.
4. Pull the sheet with both hands and steady pressure. Do not tug as you might rip the paper, leaving a piece deeper inside the machine.
5. Open the back panel to reach paper jammed between the feed-tray area and print carriage. Carefully remove the jammed paper.
6. Use the carriage access door to get at a jam further inside the printer. You may need to remove the print carriage to get to the jam.
7. Replace all parts and return any access panels to their closed and locked positions. Plug your printer back in and flip the power switch.

This can be an issue with one of the faulty sensor across the printer.
Please check if you are able to print from tray 1, e.g. a configuration page.
A config page can be printed by holding the Green Button and releasing it as soon as the Triangle light comes on. This would take approx 5 secs.
If the printer is able to print from tray 1, then it could be an issue with the tray 2 pickup sensor.
Check if the tray 2 pickup sensor ( a black plastic piece to the right of the tray 2 pickup roller) is moving freely (front and back), also check if tray 2 pickup roller is not able to rotate completely.
If the tray 2 sensor is not moving freely and of the pickup roller is rotating completely, then reseat the pickup roller.

check this out....when the printer reports the jam, open the paper tray very carefully and slowly.
Has the paper moved at all forward? Has it moved like 1/4 inch to 1/2 inch out of the tray?
If so, you probabaly need a torque limiter, no tools, $10 or so and a very very easy fix.
POBCM is very correct when he points out that the block/stop in the back of the tray moves when the tray is closed with too much force and this is the #1 cause most of the time.
You may see a "41.3" code displayed if the block is not up to the back of the paper and the paper is not all the way forward in the trays, and under the two metal clips at the front of the tray.

I was able to fix my problem. On the left side of the fuser assembly there are two small plastic tabs or flags that move up & down. One is attached to the plastic rod/flap that you can see from the top of the fuser and moves when the paper comes out of the "chute". The other tab, which is below the first tab and moves when the paper has passed some point in the fuser, was broken off. I glued the tab back on and now the paper is ejected from the printer like it is suppose to.
I'm thinking that the broken tab was part of a page sensor flag that would tell the printer to stop rolling the fuser assembly when the paper was ejected. Without the flag, the sensor would disengage the fuser prematurely and stop ejecting the paper while the paper was still in the fuser.
