Checking the Print Head
Nozzles and Remaining Ink
Levels
If you find that the printed image is unexpectedly faint or some dots in the printed image are missing, checking the print head nozzles helps you to identify the problem. You can also check how much ink remains in each ink cartridge.
Follow the steps below to check the print head nozzles and remaining ink levels using the control panel.
1.Make sure that A4 paper is loaded in the sheet feeder.
2.Make sure that this product is off.
3.Press the P On button while pressing the H Ink button. This product turns on and starts printing the test pattern.
4.Check the printout. The printout shows the test pattern and the percentage of ink remaining in each ink cartridge. The following examples illustrate when the print head needs to be cleaned.
Good: print head does not need to be cleaned yet.
Not Good: print head needs to be cleaned.
The actual printouts are printed in color (CMYK).
If the nozzle check result is not good, there is a problem with this product. It may be a clogged ink nozzle or a misaligned print head. To solve these problems, see the next two sections for details.
Cleaning the Print Head
If you find that the nozzle check result is unexpectedly faint or some dots in the printed image are missing, you may be able to solve these problems by cleaning the print head, which ensures that the nozzles are delivering ink properly.
Note:
❏Print head cleaning uses both color and black ink. To avoid wasting ink, clean the print head only if the copy quality drops (for example, blurred printout, incorrect or missing color).
❏Before cleaning the print head, perform the nozzle check first to see if it really needs to be cleaned. This saves ink.
❏If the Ink light is on to prompt you to replace an ink cartridge, or flashes to indicate that ink is low, you will not be able to clean the print head. In this event, replace the appropriate ink cartridge first.
1.Make sure this product is on, and the Ink light is off.
2.Hold down the H Ink button for three seconds.
Cleaning of the print head starts and the On light begins flashing.
cCaution:Never turn off this product while the On light is flashing. Doing so may cause damage to the product.
3.When the On light stops flashing, perform a nozzle check to confirm that the print head is clean. See the previous section for details.
Note:
❏ If the print quality has not improved after repeating this procedure four or five times, turn this product off and leave it alone overnight. Then, perform the nozzle check again and repeat head cleaning if necessary.
❏ If the print quality still has not improved, one or both of your ink cartridges may be old or damaged and may need to be replaced. To replace an ink cartridge, see “Replacing an Ink Cartridge” on page 11.
❏ To maintain good print quality, we recommend printing a few pages at least once every month.
