Hi there !

Is your printer had jammed before and it stop printing in the middle of printing? For some reasons, paper can jammed due to printing interruptions, printer turn off, improper loading or feeding of paper, roller feeder had problem and others.

If jams before and paper have let inside the printer, please do the following first:

1. Check th paper tray, see inside if the paper is jammed inside that compartment. If there is paper jammed, remove, turn off your printer and turn on. This will solve your problem.

2. If not, open the printer cartridge door, remove the toner cartridge and look for paper jammed inside. If these is paper inside, remove it, turn off the printer and turn it on.

3. If you cannot see the paper jammed inside, the paper maybe inside the heating area. To remove paper, just turn off your printer and turn it on to roll over the paper jammed inside of it.

4. If the printer is blinking and saying there is paper jammed. You have to check the cartridge toner by opening the cartridge door, remove the cartridge and return it back but be sure it is well firmly fitted.

If following the 4 diagnostic procedure and you cannot locate the jammed paper, the problem lies on the toner cartridge itself. When toner cartridge is not rolling over, it will stop feeding the paper and it will cause printer to jammed.

To diagnose the problem, put old printer cartridge and if no toner power, just shake it well and I am sure there is still small amount of powder inside it and if it prints, the toner cartridge you purchase is defective. Reason, factory defect or improper refilling and part is not working well.

I hope it is helpful and thank you for using FixYa !

To remove paper jam. Just remove the toner cartridge and pullout jammed paper. If still coming paper jammed error message. Switch of the printer and the printer will roll over the paper jammed.

Changing of fuser drum is required if the print out came with the black strips. This happens when you print large volume of printing jobs.

Check input paper feeder at top too - easy to miss. Top flips open with a firm (but not excessive) pull, so you can look there.

If you are sure you've opened and looked under every available panel on the printer (there are many!), turn it off and unplug for half a minute. Make sure all panels are back properly in place, but leave out the paper tray (and no paper either in the rear input paper feeder).

Plug in and turn on. Wait for it to finish its start-up sequence - it should complain about no paper.

Check the paper is flat and straight in the paper tray, and no excess room between paper and guides, and put it in again.

How is it now?

you probably have a piece of paper inside printer or you have damage a paper sensor path while removing jammed paper.

Most likely a bad pick up roller these machines will give a jam error if the paper or envelope is not picked up. Try cleaning the roll for the tray you are having the trouble with if the condition improves you have found the problem.
Hope this helps

Managed to solve this myself: I disassembled the printer and noticed there was a paper jammed in the duplex tray. Rolls were all ok, but the paper blocked the use of the duplex pathway. For disassembly help check the HP 1320 service manual, which you can find on the net as a PDF.

Cleaned the paper pickup unit gear & sensor, your problem will solve.

Thanks.
