Follow these guidelines as you handle the white ink packs:
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 packs at the start of every working day or every 24
hours, and shake them well before reinstalling them.
When storing
ink packs, lay them down flat and keep them level. If you store ink
packs standing upright, shaking the ink packs may not sufficiently
clear the sedimentation.
If white ink
packs are loaded in the printer and the printer will not be used
for more than two weeks, use an optional cleaning ink pack and
perform long-term storage maintenance. Otherwise, it may be
impossible to clear clogging in the print head. See the link below
for more information.
Note: White ink is
consumed during maintenance even when printing only with color
ink.
