White Ink
05/11/2020
All white ink has titanium dioxide.

Over time, if white ink is left
sitting, the titanium dioxide will
separate from the water, causing the
ink to settle or separate apart.
It's vitally important to remove your

white ink cartridges daily and shake
them around. This will mix any
separation that might have
happened overnight. The printer will
prompt you to gently agitate the
white ink cartridges every 12 hours.
If white ink is kept in stock, rotate

cartridges 2-3 times a week.
White ink has a shelf life of 6

months. CMYK shelf life 1 year.
Each cartridge has a label for its
specific channel.
