Hp laserjet 4200 will print a 50 page paper path test, print an extra page and then jam.

If your HP LaserJet 1200 printer is experiencing intermittent printing issues, there are a few steps you can take to troubleshoot and resolve the problem:
1. Check for paper jams: Even if you don't see any visible paper jams, it's worth opening up the printer and checking for any small bits of paper or debris that might be causing a partial blockage. Use a flashlight to examine the paper path thoroughly.
2. Clean the paper path: Over time, dust and debris can accumulate in the paper path, leading to printing problems. You can use compressed air or a soft, lint-free cloth to gently clean the rollers and other accessible parts of the paper path.
3. Verify printer drivers: Ensure that you have the latest printer drivers installed on your computer. Outdated or incompatible drivers can cause printing issues. Visit the HP website and download the latest drivers specifically for the HP LaserJet 1200 printer model.
4. Reset the printer: Perform a power cycle by turning off the printer, unplugging it from the power source, and waiting for a few minutes. Then, plug it back in and turn it on again. This process can help clear any temporary glitches or errors.
5. Adjust printer settings: Check the print settings on your computer and ensure they are appropriate for the print job. Make sure you have selected the correct paper size, paper type, and print quality settings.
6. Update printer firmware: Visit the HP support website and check if there are any firmware updates available for your printer model. Updating the firmware can address known issues and improve the printer's performance.
7. Check for hardware issues: If the problem persists, there might be a hardware issue with the printer. Consider contacting HP support or a printer technician to diagnose and repair the printer.
Remember to consult the printer's user manual for specific instructions on maintenance and troubleshooting.

Check the backstop in the paper cassette. Print out a configuration page and make sure the cassette is set for letter size.

Open the paper feed area and the printer, examine the paper feed path and make sure there isn't a page or piece of paper jammed in the path somewhere.

First you need to verify that tray 2 will print from diagnostics test. Use the arrow keys to scroll down to diagnostics and press arrow key, then use arrows move to paper path test and press arrow again. The default paper path test is tray 2 single copy so just select print paper path test and see what happens. If printer prints from tray 2 then we know tray 2 works and that means you either have a print driver that is forcing printing from tray 1 or your settings on the printer for tray 2 are not correct for what you are printing. Check to make sure the paper size shows correctly and make sure that the switch on the right side of the paper tray towards the back is set for standard and not custom.

Jams

Clearing jams

CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams.
Damage caused by sharp objects will not be covered by the warranty.

CAUTION Always pull jammed media in the direction it would travel through the paper path.
Do not pull jammed media against the direction of travel through the paper path to avoid damage
to the printer.

To prevent damage to the printer when clearing jams, including jams in the output bin, always open the
print-cartridge door and remove the print cartridge. Keep the door open and the cartridge out until the
jam has been cleared. Opening the print-cartridge door and removing the print cartridge relieves tension
on the printer rollers, which prevents damage to the printer and makes the removal of jammed pages
easier.

Occasionally, media becomes jammed during a print job. You are notified of a media jam by an error
from the software and the printer control panel lights. See Control-panel lights (HP LaserJet 1010 series
printers) on page 102 or Control-panel lights (HP LaserJet 1020 printer) on page 106.

The following are some of the causes of media jams:

?

The input trays are loaded improperly or are too full. See Loading media on page 25.

NOTE When you add new media, always remove all of the media from the input tray and
straighten the stack of new media. This helps prevent multiple sheets of media from feeding
through the printer at one time, reducing media jams.

The media does not meet HP specifications. See Media specifications on page 21.

Print cartridge area: See Removing a jammed page on page 43.

Input tray area: If the page is still sticking out of the input tray, gently try to remove it from the input
tray without tearing the page. If you feel resistance, see Removing a jammed page on page 43.

Output path: If the page is sticking out of the output bin, see Removing a jammed page


NOTE There might be loose toner in the printer after a media jam. This toner clears up after
a few sheets are printed.

Removing a jammed page

Use the procedures in this section to remove a jam.

CAUTION Media jams might result in loose toner on the page. If you get any toner on your
clothes, wash them in cold water. Hot water will permanently set the toner into the fabric.


Partshere Troubleshooting

CAUTION To prevent damage to the printer when clearing jams, including jams in the output
bin, always open the print cartridge door and remove the print cartridge.

jams. Damage caused by sharp objects will not be covered by the warranty.

CAUTION Always pull jammed media in the direction it would travel through the paper path.
Do not forcefully pull jammed media against the direction of travel through the paper path to
avoid damage to the printer.
