If colors are broken or missing, clean the print head.
If lines are not aligned properly, align the print head.
If any portion of the Nozzle Check Pattern is streaked, the print head
could be clogged, may not be aligned properly, or the BJ cartridge may be
worn out.
If the problem persists after cleaning the print head and aligning the print
head, try replacing the BJ cartridge.
Note If the Nozzle Check Pattern prints normally, there may be a problem in the
application program. For details, refer to the Troubleshooting sections of
the documentation of your application program.
