4. Press Enter. The power light on the printer flashes and the printer
begins cleaning the printhead. This takes a little over a minute.
When the printer is done, print a test page to inspect image quality:
1. Press Esc several times until you see the main menu:
Table 5-11. Main Menu
2. Select Print A4 Pattern, and press Enter twice. In a few seconds,
the test page begins to print.
3. After the test page prints, inspect the test patterns for missing dots
or lines. If you see any gaps in the patterns, clean the printhead
again as described above. Note that it may take as many as seven
or eight cleaning cycles to clean the printhead fully.
If this still doesn't work, you can perform the initial ink charge
sequence. This uses a lot of ink but is the most powerful way of
cleaning the printhead. See "Initial Ink Charge" on page 145.
4. When you're done, press Esc repeatedly to return to the main menu
or exit the program.

If your printing results get worse each time you clean,
