Improving Print Quality

Cleaning the Print Head

Using the Head Cleaning utility
Using the control panel buttons

If you find that the printout is unexpectedly faint or that dots are missing, you may be able to solve these problems by cleaning the print head, which ensures that the nozzles are delivering ink properly.

You can clean the print head from your computer using the Head Cleaning utility in the printer software or from the printer itself by using the printer's control panel buttons.

Note:

Print head cleaning consumes some ink. To avoid wasting ink, clean the print head only if print quality declines; for example, if the printout is blurry or the color is incorrect or missing.

Use the Nozzle Check utility first to confirm that the print head needs to be cleaned. This saves ink.

When the error light is flashing or on, you cannot clean the print head. Replace the appropriate ink cartridge first.

Using the Head Cleaning utility

Follow the steps below to clean the print head using the Head Cleaning utility.

Make sure that the printer is turned on and the error light is off.

Note:

If the error light is flashing, you cannot clean the print head. Replace the appropriate ink cartridge first.

Access the printer software.

Accessing the Printer Software

Click the Maintenance tab, then click the Head Cleaning button.

Follow the on-screen instructions.

The power light flashes while the printer performs the cleaning cycle.

Caution:

Never turn off the printer while the power light is flashing. Doing so may damage the printer.

When the power light stops flashing, load a few sheets of paper and click Print Nozzle Check Pattern in the Head Cleaning dialog box to confirm that the print head is clean.

Below are two sample nozzle check patterns:

Good sample

Print head needs to be cleaned

If the nozzle check page does not print satisfactorily, you may need to repeat the head cleaning and print the nozzle check pattern again.
See Cleaning the Print Head

Note:

If print quality has not improved after repeating this procedure four or five times, turn the printer off and leave it alone overnight. Then, do the nozzle check again, and repeat the head cleaning if necessary.

If the print quality still has not improved, at least one of your ink cartridges may be old or damaged and may need to be replaced.
See Replacing an Ink Cartridge to replace an ink cartridge before it is empty.

If print quality remains a problem after replacing the ink cartridges, contact your dealer.

To maintain print quality, we recommend printing a few pages at least once every month.

Using the control panel buttons

Follow the steps below to clean the print head using the control panel buttons.

Make sure that the power light is on and that the error light is off.

Note:

If the error light is flashing or on, you cannot clean the print head; this operation will start the ink cartridge replacement procedure. If you do not want to replace an ink cartridge at this moment, press the maintenance button again to return the print head to its home position.

Hold down the maintenance button for three seconds.

Note:

If you release the maintenance button earlier than three seconds, paper will feed. If you press the button longer than six seconds, the print head will move to the ink cartridge replacement position. Press the maintenance button again to eject paper or to return the print head to the home position, and then repeat step 1.

The printer starts cleaning the print head and the power light begins flashing.

Caution:

Never turn off the printer while the power light is flashing. Doing so may damage the printer.

When the power light stops flashing, print a nozzle check pattern to confirm that the head is clean.
