Print Test Pattern.
This option prints a test pattern like those shown in figures above. Gaps in
the pattern (example B) indicate a purge (cleaning) is required.
Clean Printer Nozzle
This option allows you to select from four purges: A, B, C or D. These are
described in Table 3-2. The Operator Guide advises operators to perform
purge A. Purges B and C are stronger because the suction time is three
times longer than it is for purge A. (Purge B is a cartridge replacement
purge; purge C is a print head replacement purge.) Purge D, which consists
of wiping and spits only (no suction), is a weak purge.
When the purge is complete, the display offers the options of printing an-
other test pattern, selecting another purge or returning to the Printer Mainte-
nance Menu.
Replace Ink Tank (Cartridge)
Replace Print Head
These submenus are identical and self-prompting. When you select this op-
tion, the display prompts you to open the top cover, at which point the print
carriage automatically moves to the tank/print head replacement position.
The display then prompts you to install the replacement and close the cover
when done. Closing the cover initiates a purge that's appropriate for the re-
placement part. When the purge is complete, the display offers the option of
printing a test pattern.
