Yesterday, I was trying to help a firend fix their HP printer, it was making lines in the print missing half the black and only printing the bottom half of words.

 

I installed and ran HP Print and Scan Doctor. No improvemet. Next I did PEN CLEAN 1/PEN CLEAN 2/PEN CLEAN 3 as described in this HP Support video on YouTube https://www.youtube.com/watch?v=XmQ1DD5uBjE and it improved to printing most of the letters, but still showed lines in areas that contained a picture. Not perfect, but good enough.

 

Then this morning, it stopped printing black entirely. I found this HP support document https://support.hp.com/in-en/document/ish_4513548-4025581-16 but I ran into a few road blocks.

1. The printer doesn't display an error for having a printhead issue, but it has stopped printing black entirely.

2. The printer doesn't move the carriage when I lift the ink access door. It says to the far right side of the printer and I cannot check the printheads as suggested. How do I make it move? It seems this is supposed to be automatic.

3.  We reset the printer as describded and no improvement.

 

Any help would be greatly appreciated, they own a small business and this is their main printer.
