Tips for a great answer:
a single inkjet in your printer is not functioning then output will appear as a
horizontal line across the page. If one of the jets is on all of the time then
output will have black or colored lines across the page. Use the following
steps to isolate the problem:
Replace the ink cartridge
Check the flexible cabling for continuity and for short circuits between
Exchange the control board for a good one
Finally check the power supply
