Fitting the
Squeegees
It is usual to fit two trailing edge squeegees and use the machine in the Print/
Print mode.
When fitting a single squeegee (trailing edge or diamond section) to the
machine, it must be fitted to the front squeegee mount only.
The following procedure describes a double trailing edge squeegee configura-
tion fit to the machine printhead mounting assembly.
1. From the Start menu select Setup Product - Setup Squeegees.
