Follow these guidelines as you handle the white ink
cartridges:
White ink
particles may settle in the ink system, which must be maintained.
Do not print without maintaining the White ink system; print
quality may decline or the printer may not work properly.
Remove the
White ink cartridges at the start of every working day or every 20
hours, and shake them well before reinstalling them.
When storing
cartridges, lay them down flat. If you store cartridges standing
upright, pigments may settle and reduce print quality.
If you do
not use the printer for more than two weeks, print a nozzle check.
Alternately, you can also replace the White ink with cleaning
cartridges (Maintenance >
Replace White Ink). If the printer
is left without replacing the White ink, the print head nozzles may
become clogged.
Note: White ink is
consumed during maintenance even when printing only with color
ink.
