Head Cleaning - Brother GT-3 Series Service Manual

Execute Head Cleaning if you have the print as shown in the below:
Several continuous nozzles are
missing like a "band".

2-6-4. Head Cleaning

Your printer automatically cleans its Print Heads every 24 prints (you can change the frequency; see "7-2-5.
Changing the Auto Cleaning Setting" in the Instruction Manual), or when your printer has not been used for
more than two hours. The auto-cleaning starts when you press the Print Button in these situations. However,
the auto-cleaning may not be enough and cannot solve print quality problems (e.g. stripes/ banding appears
on the printed image). Please do the "manual" head cleaning.

Heads of either CMYK or Whites have mis-firing at the same time.
The message "Head Cleaning..." appears and your printer starts cleaning the Print Heads.
The message changes to Print Head Selection menu when the head cleaning has been completed.
