7.2 BI-DIRECTIONAL ADJUSTMENT
The Bi-directional (Bi-D) Adjustment is used to set the timing of a print head when using bi-directional
printing. It ensures that the left-to-right pass of the carriage (Adjustment Pass) is aligned with the right-to-
left pass (Reference Pass). It should be performed whenever the printing environment or the media type
is changed.
Step 1 : Power ON the printer and setup the media at the control panel.
Step 2 : Print the Bi-D Test Print. At the control panel, navigate to Setup Menu 1/7 and select F3
TestPrint > F4 Adj. Bi-D.
There may be a slight delay between the time that the Bi-D Test Print is selected and the time
that it actually prints.
Step 3 : Analyze the Bi-D Test Print. Beginning with Print Head 1A, observe the Adjustment Lines in
relation to the Reference Lines. Select the number (1 – 7), on left side of the test print, where
the Reference Line and the Adjustment Line are best aligned.
For example, in the figure below, number “4” is where the Reference Line and the Adjustment
Line are aligned the best for Print Head 1A.
