When Printing Becomes Faint or Colors Are Incorrect
If print results are blurred or colors are not printed correctly, the print head nozzles are probably clogged.
Follow the procedure below to print the nozzle check pattern, check the print head nozzle condition, then
clean the Print Head.
If printed ruled lines are misaligned or print results are otherwise unsatisfactory, aligning the Print Head
may improve print quality.

Do not rinse or wipe the Print Head and ink tanks. This can cause trouble with the Print Head and ink
tanks.
Note
Before performing maintenance
Make sure that the orange protective tape does not remain on the ink tank.
Refer to " Troubleshooting " in the on-screen manual: Advanced Guide
Open the Scanning Unit (Cover) and make sure that all lamps on the ink tanks are lit red.
