2.5.2 When adjustment of the print head position is required

When replacing the print head, good print quality may not be obtainable due to
changes in the dot placement points caused by the individual differences and the
installation state of the BJ cartridge. To prevent this misalignment, use the printer
driver utility to conduct the automatic head position adjustment after the BJ cartridge
is installed. Set a sheet of A4/LTR-sized plain paper and perform the head position
adjustment pattern in [Test print] in the printer driver's [Maintenance].

print will contaminate the platen with ink.
