Black cartridge was almost empty and started to print horizontal lines. Replaced black toner 2 x and tried various resets and cleanings, initializing etc as per HP Chat line but black lines persist. No service centre in my area (Wasaga Beach - 1 3/4 hr north of Toronto, Ontario, Canada). Color cartridges all at least half full. Had similar symptoms when yellow got low, but problem fixed as soon as replaced yellow. Any ideas?

The product you have seems to be a commercial printer. For the best chance at finding a solution I would suggest posting in the forum for HP Business Support!
You may find the Commercial Laserjet board here.
Hope this helps!
