Post / thumbs / testimonial are welcome!

check ur print options before printing

is it laser or inkjet, and cartridges are original ones or compatible ones, some printers will not accept comptible cartridges.

Most likely you left the tape on the new cartridges which protects the printhead. Remove the cartridges, pull the tape off and reinstall the cartridges. If the tape was already off, double check to make sure they are the right cartridges. Good luck!

There are 2 fuses inside the power supply unit.

The hard part is getting to the power supply! The power supply is located at the left side of the printer and in the front (the opposite side of the cartridges).
You have to remove the side and top covers.
There are some hidden screws. One is under the button faceplate that you will also have to remove. The entire procedure is tricky especially without a service manual. Unfortunately I couldn’t locate a manual.
Caution always disconnect the power lines and allow some time for capacitors discharge before you attempt any repairs.
I hope you have some luck with yours !!

Try installing cleaning cartridges and running a clean test again. If that doesn't help then contact Hp because the print head is probably damaged.

Sounds like one or more of your printheads is worn out. They are designed to be user replaceable, and wear out after a certain amount of usage.

Black is obvious, but if the lines are purplish, your yellow head is bad. If they're greenish, your magenta head is bad. If they're reddish, your cyan head is bad.

Vertical lines are very unusual. Can you scan a printout and post it somewhere that we can look at it?
