Head Cleaning

The auto nozzle check function is installed to the printer, and the head is automatically cleaned
in the normal operation. However, when dot missing occurs, the print result may not be clear or
print in the abnormal colors depending on some settings due to the clogging of the print head.
Clean the head in that case.
Use [maintenance and utilities] function on the printer driver to run head cleaning.
Make settings with [Missing Dot Operation] on [Maintenance And Utilities] tab when dot is
missing. (See
