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 ink cover 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.
