Hp 2820 prints only on right side of page

If its connected through net work try with lj 4200 drivers..

the problem is due to scanner mirror dust.you have to clean the scanner mirror.

Install the HP LJ III driver and this should work as advertised.

The mfr. & model don't seem right; Dell does have a 5100 but the LJ designation is copyrighted by HP who has a LaserJet 5100.
The rotating drum that transfers the image to paper is smaller in circumference than the paper is long; this accounts for the shadow and the streaks come from the drum no longer being properly discharged and cleaned for the next pass.
I think you need a new drum cartridge and whether Dell or HP made it, you should be able to buy a drum cartridge here:
Precision Roller 
I used them for years while in business and they are great to work with.

Follow the link and get the correct driver and get installed

Also try with another USB cable, If you are using a long cable, just try with a short one.

ok typical carousel misalignment

just take a big screwdriver and check for stuck cartridges

Have you tried a new Imaging drum?

Try changing to a new USB cable

Hi there in the paper handling menu check the paper size settings as it maybe as simple as the incorrect paper size has been set in the machine


Hope this works for you
Thanks J
