CHECKING WHITE INK FOR SEDIMENTATION
Use an agitation machine to properly break up sediment. Different types of agitation
machines vary in the time it takes them to properly agitate white ink. A gyroscopic mixer takes
about 5 minutes to agitate, while a vibrating plate can take up to 2 hours.
After agitation, let the white ink settle for 10 minutes. This gives the white ink time to dissipate
any foam that may have appeared during the agitation process.
Turn the container upside down and use a flashlight to view the sediment. Move the
container around gently to clear any foam that has appeared.
A flashlight will review the amount of sediment in the container. Look for dark areas of
more solid material. If ink has no sediment, it is OK to refill the tank. An example is below:
Repeat Agitation Steps If Any Sediment Remains
> The shadows of bubbles may be mistaken for sediment after the white ink agitation, so wait until bubbles
disappear before checking the container for sediment.
> To distinguish between bubbles and sediment, lightly shake the replenishment ink container. The shadows
of bubbles move but the shadows of sediment do not move.
When handling bulk ink containers, you will need specialized tools to help you in your daily
workflow. 20 Kg [18 L] bulk ink containers are heavy and cumbersome, which necessitates
the use of both a hydraulic scissor lift and an agitation device. These specialized tools will
help to professionally move and agitate the inks before filling the tanks on your printer.
