Hello,
I realize this topic has been addressed before, but wanted to make sure I had tried everything to fix this issue. After replacing the black ink cartridge on my 6830, the printer would not print black. This held true for printing test pages, copies, and prints from the computer. We initially thought it might be a defective cartridge and tried a second one, only this one had the same issue, though would occasionally print the outlines of black prints. The diagnostic page with the second cartridge will print the grayscale test areas, but not the full black.
To attempt to fix this I have tried:
- Updating the printer firmware.
- Reinstalling the Windows drivers.
- Unplugging the printer, waiting several minutes, holding the power button to disperse charge, and turning it back on.
- Cleaning the contacts of the black cartridge.
Nothing seems to be working unfortunately.
