Question about HP LaserJet 1020 Printer
Had a paper jam. Removed and cleared the jammed print. Now the printer never completes the print cycle. It stops printing/jams every time half way through the print cycle (where the paper/print just begins to feed out of the printer about 2 inches then stops/jams). Stops feeding/jams at this same point every time. Any suggestions??
Maybe if you hold down the cycle button and let it run through a "test cycle" to receive a printer data sheet it might clear the internal buffer or whatever you call that short term memory these printers have. Let us know. JP

Had a similar issue. The feed was stopping halfway through, same spot every time....
Turned out to be the paper pickup solenoid. The solenoid was stuck to energized and kept feeding sheets, one right after the other.... as a result, the end of page sensor was not detecting the end of the page - there was no gap between the pages - and was calling a paper jam.
The solenoid is located at the rear bottom right of the printer, when facing the front... You have to remove the right plastic cover...
Check that after the solenoid is energized and the page is fed, the solenoid lever returns to the open position, i.e. not stuck on the electromagnet... If it remains stuck on the electromagnet, the sheets keep feeding back to back and paper jam...
You can try pushing it open manually with a long screw driver after the page is fed, to see it this will solve your problem...
If indeed you have a jamming solenoid, you can try the following fix...the problem seems to be that overtime the solenoid core and/or lever become magnetized and the force of the return spring is not enough to pull the lever back to the open position.... an adjustment needs to be made to the spring so that fewer coils are used and the spring becomes stiffer, and hence able to pull back the lever... the solenoid has to be removed.... at the bottom you can see the return spring... pull the little mounting ring at the end of the spring off of the mounting pin at the bottom of the lever...and then use one of the spring's coils at 2/3 to 3/4 of the length (don't make it too stiff!) to hook it again on the pin... effectively reducing the spring's length ....
This worked for me! Printer is working fine now!
Please unplug the device and remove residual current before attempting repairs. If you are unsure about what you are about to do, get expert advice...Dangerous voltages and/or other hazards are present inside electromechanical devices. Use the above guide at own risk!

Pls check the fusing assembly,something might be stuck or the flag of paper jam sensor might be broken or could have come off.
