Question about HP DesignJet 100 Plus InkJet Printer
Hello. You may have air in the black ink tube. If so, when you put a new print head in the plotter, it will print with the ink from the factory and then draw air into the print head and cause the symptoms you described. Purge the tube system and replace the black print head (unless you can disassemble and refill with ink - something I have not tried). Try this: Designjet Ink Tube Priming Tool

You can try to disassemble the printhead and check for contamination.
First remove cap 1
than using a small flat screwdriver disassemble printhead (engagement points 2 and 3)
Warning - a printhead is filled with 8 ml ink
After disassembly - clean the printhead with fluid compatible with pigment ink (for black color) or compatible with water based ink (color printheads)
during reassembly - don't forget to fill the printhead with ink (2/3 of its volume)
