When Printing Becomes Faint or Colors Are Incorrect
If print results are blurred or colors are not printed correctly, the pint head nozzles are probably clogged.
Follow the procedure below to print 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.
Caution
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
Open the Top Cover and make sure that all lamps on the ink tanks are lit red.
If not, see
Checking the Ink Status
and take an appropriate action.
Increasing the print quality in the printer driver settings may improve the print result.
For details, refer to the on-screen manual: Advanced Guide .
