have 59.3 error on my printer hp laserjet pro 300 color what to do??

- clean the scanner optics
- if this don't work check and replace drum cleaning blade

I had the same problem; it happened with the first copy I tried to make directly from the printer's console - but only with the Black ink function - with the same original on the flatbed glass I then tried the Color function and it worked fine. But when I tried the Black copy function, the strong vertical lines appeared again - about 7, evenly spaced across the page and running the entire length of the page.

Nothing about cleaning any part made sense: the printer was brand new, out of the box, the color ink function worked fine to copy; so did making scan copies. It was only the black ink mode in the copy function with the original on the flatbed glass that produced the vertical lines.

What cleared it up was shutting it down, removing and re-inserting the power cord the other way, i.e., turning it around (which might have nothing to do with the outcome) and Voila! - no vertical lines with the black ink copy function - Go figure...

Probably either the scan lamp or the sensor bar has failed. Do you see the scan lamp glowing under the cover when you try to scan a document? (Lift the edge of the cover slightly and watch the underside of the cover, you should see the reflection from a bright bar of light moving from one end of the original to the other. Do not look directly down into the light if it is on!)

Hi, Change first black color print head cartridge just open cover then replace black print head cartridge.close cover wait for ink cartridge reinitialize if ready print test again.if same print having black line all copy needs to replace also black ink cartridge.
