Image Problems
1. Are the ink nozzles clogged?
Print out the nozzle check pattern and check if any of the nozzles are
clogged. If there is a blockage, perform the cleaning procedure on the
print head(s) in question. If any of the lattice patterns show ink mixing
(e.g., yellow ink appears on the lattice pattern for black), perform
cleaning on the print head for that lattice pattern.
Note: In some cases, this will only solve the problem temporarily. If the
problem persists, clean the maintenance unit.
2. If none of the above work
The machine needs to be repaired:
• Replace the maintenance unit. Ink has built up or the unit has
failed.
Output dirty, ink running
