Minimizing Print Misalignments (Head Alignment)

Because there is a small distance between the print head and paper, misalignment may
occur due to humidity or temperature, the inertial force of the print head's movements, or
by moving the print head bidirectionally. This may result in grainy prints or lines that are
incorrectly placed. When this happens, perform Head Alignment to correct the print
misalignment.
For head alignment, you need to check the pattern and enter the optimum adjustment
value for alignment.
Printing the pattern for manual head alignment takes from 7 to 11 minutes. The time
required varies with the size of the pattern printed.
You can select between Uni-D and Bi-D head alignment. Bi-D is recommended in most
circumstances. Choose Uni-D if Bi-D head alignment does not completely fix the problem.
