Maintenance Procedure
If print results are blurred or colors are not printed correctly, the print head nozzle is
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.
Important
Do not rinse or wipe the print head and ink tank. This can cause trouble with the print
head and ink tank.
Note
Before performing maintenance
Make sure that the orange protective tape does not remain on the ink tank.
Open the operation panel and make sure that the lamp on the ink tank is lit red. If the
lamp is flashing or off, take appropriate action.
Checking the Ink Status with the Ink Lamps
Increasing the print quality in the printer driver settings may improve the print result.
