Cleaning the Print Heads
If your printed image is unexpectedly light or faint, or dots are
missing from the image, you may need to clean the print heads.
This unclogs the nozzles so they can deliver ink properly.
Cleaning the print heads uses ink, so clean them only if print
quality declines. You can clean the print heads in either of the
following ways:
◗ With the Head Cleaning utility in your printer software
(when Status Monitor 2 is installed)
◗ From the printer’s control panel buttons
Using the Head Cleaning Utility
Follow these steps to run the utility from a Windows computer
or a Macintosh:
1. Make sure the printer is turned on but not printing, and
the B black and A color ink out lights are off.
2. Access the printer settings dialog box as described in
Chapter 1.
3. Click the Utility tab (Windows) or the Utility button
(Macintosh). You see the Utility menu.
4. Click the Head Cleaning button.
5. Follow the instructions on the screen to clean one or
both print heads. Cleaning both heads takes about four
minutes, during which the printer makes some noise and
the
Ppower light flashes.
When the power light stops flashing, you need to run a
nozzle check to test the print quality and reset the cleaning
cycle.
Caution:
Never turn off the printer
while the
P power light is
flashing, unless the printer
hasn’t moved or made any
noise for more than 10
minutes.
