Adjusting print misalignments
(Head Alignment)
If lines are misaligned or print results are grainy,
perform Head Alignment to adjust the print
misalignment.
The print head fires ink when moving to the left and
to the right while printing. Since there is a short
distance (gap) between the paper surface and the print
head, a print misalignment may occur due to the
paper thickness, changes in temperature or humidity,
and internal inertia while the print head moves.
Although Head Alignment can be performed from the
computer or the printer, the alignment procedures
differ as explained below.
From the computer
In auto adjustment (Bi-D 5-color), an adjustment
pattern is printed on the loaded paper, read by the
sensors, and the optimum adjustment value is
registered to the printer. It takes about 3 minutes to
complete the adjustments.
In most cases, head alignment can be performed
successfully with just this operation. We normally
recommend this method as this is the simplest method.
