How to Maintain White Ink

How to Maintain White Ink
Introduction
Printers with the White Ink Option require care and maintenance to ensure
that the white printheads function properly. White ink is re-circulated in the
system to limit any settling of the ink. For this to take place, the printer
must be left powered On at all times. If the printer is powered down for
maintenance or service, once it is powered on again and the ink reservoirs
are full, agitate the white ink bag and perform several purges.
A new white ink bag must be gently agitated before it is connected and
then at least once a week thereafter. Daily maintenance is essential with
the white ink option as it will purge out a small amount of white ink in
order to keep the printheads clear and operating reliably.
Printers with the white ink option will spit into the "spit catcher" (located
over the maintenance tray) every few minutes in order to keep the white
nozzles clear.
When to do
Daily
• Perform printhead maintenance every day for all colors, including white.
Weekly
• Agitate the white ink bag as described on the ink bag label (even when
white is not actively used)
• Swab all printheads
As Needed
• Purge the white printheads as required (i.e., if there are too many nozzle
dropouts). This may be necessary multiple times per day.
Before you begin
Make sure you wear eye protection and nitrile gloves when handling or
cleaning ink. Also, when working around the maintenance station take
measure to protect your clothing and any exposed areas of skin.
IMPORTANT
Failure to properly maintain the white ink as described here can result in
damage to the printheads.
NOTE
Clean-up required (origin steplist/pxt)!!!
