7-2-4. Changing the Print Direction
When there are large gaps between the Print Heads and printed medium, or when printing on very high absorbent
material, horizontal stripes and color graining can appear on the printed image. You can solve this problem using
one-way "Uni-Directional" print. If you adjust to a larger gap then we recommend this mode is used. Keep the
clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm by adjusting
the Platen Height.
If you already know that a print data will be printed in uni-directional printing before you print, you can set with the
Printer Driver. This setting is available when the printer’s setting is [ Auto ]. See “4-3. Setting the Printer Driver
Condition” and “4-3-14. Setting Print Direction as Uni-Directional”.
(1) Select [ Print Direction ] with Up/Down Button from the menu and press the OK Button.
(2) Select [ Always Uni- ] when you print one-way "Uni-Directional" printing. Select [ Always Bi- ] when you print
by-directional even if the Printer Driver setting is Uni-Directional Printing with Up/Down Button and then press
OK Button. This setting is always available until you change the setting.

<Note>
Uni-Direction Icon is on the Display of the Control Panel.
The default setting is "Auto", which follows the Printer Driver setting. (Check-OFF Uni-Directional Printing)
The printer setting is prior to the Printer Driver setting. Even if the checkbox "Uni-Directional Printing" is
checked, when the printer setting is "Always Bi-" then the print is Bi-Directional.
7-2-5. Changing the Auto Cleaning Setting
GT-3 automatically cleans its Print Heads every 24 prints. However more frequent Print Heads cleaning needs to
be done depending on the environment. In this case, change the Auto Head Cleaning frequency as follows.
<Note>
This setting is available with Color / White separately.
(1) Select [ Printer Setting ] with Up/Down Button from the menu and press the OK Button.
(2) Select [ Auto Cleaning ] and press the OK Button.
The following display appears.

(3) Press the Up/Down Button to select the frequency from 1 to 24, and then press the OK Button.
The Auto Cleaning will be executed at every number of prints you have set.
<Note>
Cleaning the Print Heads frequently may hasten the Wiper Cleaner consumption.
