An HP 13.B4.CD error indicates a paper jam in the right door and fuser area of compatible LaserJet printers. To resolve it, first wait for the printer's fuser to cool, then open the right door, and gently remove any jammed paper. Check the duplex area and around the fuser. After removing all paper, close the door and the printer should resume.
Step-by-Step Instructions
Wait for the fuser to cool: The fuser gets very hot, so wait for it to cool down before touching anything inside.
Open the right door: Locate and lift the latch to open the right-hand door on your printer.
- Check for jammed paper:
Look for any paper jams in the main area of the right door.
Check the duplex path, which is the path the paper travels for two-sided printing.
If you see paper entering the bottom of the fuser, gently pull it downwards.
- Remove the fuser (if necessary):
If paper is jammed deep inside, you may need to remove the fuser. Grasp the fuser handles, squeeze the green release levers, lift slightly, and pull the fuser straight out.
Open the small jam-access door on the fuser itself to find any paper lodged inside.
Gently pull any paper out.
- Reinstall the fuser:
Close the jam-access door on the fuser.
Push the fuser completely back into the printer until it clicks into place.
Close the right door: Ensure the door is shut properly.
- Check output bin: Inspect the output bin for any paper that might be stuck there.
If all the above fail. Please check if there are any non contracted toners inside the printer, this can also cause this issue. For example if you have used an ink toner from a different printer, then please place this back into the original printer, and try to use a toner that is specifically for this printer and re-test after printer power cycle
