Printers with the White Ink Option require 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.
A new white ink bag must be gently agitated before it is connected and then once a day thereafter. Daily maintenance and agitation is essential with the white ink option to keep the printheads clear and operating reliably.
Daily
Perform printhead maintenance for white ink.
Agitate the white ink bag.
Weekly
Swab white printheads (use flush or 99.9% isopropyl alcohol).
NOTE
Extended Idle Time
Swab the White printheads with flush prior to letting the printer sit idle for an extended period of time. It has been demonstrated that leaving flush on the printhead nozzle face plates helps minimize the amount of maintenance required to recover nozzles after an idle period.
IMPORTANT
Failure to properly maintain the white ink as described here can result in nozzle dropouts that degrade print quality.
NOTE
You will see a message on the printer display that reminds you to agitate the white ink bag once a day.
NOTE
You must agitate the white ink bag for at least 5 seconds or the message will remain on the screen.
