 Do not remove the ink cartridge.
If the ink cartridge insertion slot is left empty, the inner needle may clog because ink dries up, or the printer may
be damaged.

Take care to prevent the ink pouch from being bent, snagged by sharp objects, or dropped.
Otherwise, it could be damaged.
About pretreatment

Avoid application of the pretreatment when no white ink is used.
If a T-shirt to which the pretreatment is applied is coated with only color inks, its stains may be wiped off by
washing.

After a T-shirt is coated with the pretreatment, store pretreatment in a place where it is not exposed to
direct sunlight, and wash it with clean water at an early stage after ink is applied to it.
When a white or light-colored T-shirt is coated with the pretreatment, the coated surface color may change, and
cannot be restored to the original color even if the T-shirt is washed.

When performing printing for the first time, try pretreatment in an unnoticeable area.
Some T-shirts may be discolored by the pretreatment and cannot be restored to the original color even if they
are washed.

Wash away any imprint of the pretreatment with water.

When a color transfer occurs, wipe the color-transferred area clean of dirt with a soft and clean cloth or
a toothbrush that is moistened with a small amount of mild detergent for home use or alcohol.
If a printed material is rubbed with vinyl-chloride-based white or light-colored synthetic leather, color transfer
may occur. Also, when a color-printed surface is rubbed strongly against a printed surface with only white ink,
color transfer may occur in the same fashion.
About maintenance

In order to keep good printing quality, perform maintenance on a regular basis.
☞"7. Precautions to keep good printing quality/use printer over the long term >>P.168"

We recommend to use the genuine cleaning solution that is specified by us when cleaning the head
section, cap or wiper.
This allows you to take full advantage of the printer's intrinsic capabilities and use it for a long period.
Using commercially available alcohol or cleaning solution could cause damage to the print heads.

Never remove the print heads except when they are replaced with new ones.
Because they are precision components, the print head may fail.
What to do when not using printer

When the printer will not be used for a prolonged period of time, take appropriate procedures before
storing the printer depending on storage period or condition.
