Purge ink delivery lines

If you are using one set of ink lines for several ink types, you must purge the
ink lines and rinse them with distilled water thoroughly before changing to a
new ink type. You will then have to reprime the lines as described (see 'Prime
the ink delivery lines' on page 30).

Select ink preheat

Cartridge preheat settings are optimized for media being printed in a standard
office environment. If you are experiencing banding, poor fills, or over dot
gain, and you have tried all other means to correct these conditions, you may
want to experiment with the ink preheat settings. These will vary depending on
the ambient temperature where the printer is located and the media and ink
used.
Defaults for the heater setting are determined by the ink type in use.
Default = 0 for each cartridge. This does however not mean that the absolute
values are the same for each cartridge. 0 for Magenta might be a different
setting as 0 for Cyan. The printer determines the ink type by reading the chip
on the back of each cartridge. When you adjust the ink settings, you are
increasing or decreasing the heat from the default temperature. Pressing the
'Previous' and 'Next' buttons increases or decreases the temperature. When
you have reached the limits of the temperature range, the panel will display
either MAX or OFF. These settings are saved in the printer. If you change to a
different type of ink, you may need to change the heater settings to
accommodate the new ink type.
