You can choose between the following different modes for printing:
• Screen printing:
1: Move in – Print – Flood – Move out
2: Move in – Print – Flood – Print – Flood – Move out
• Stencil printing:
3/3a: Move in – Print – Print – Move out
4/4a: Move-in – Print – Move-out (forwards/backwards alternately)
Note:
Pay attention to the fact that depending on which printing mode you
choose either one printing squeegee and one flooding squeegee or
two printing squeegees must be used.
Screen printing mode 1
After the foot switch is pressed, the table moves into the print area and is
raised. The rear squeegee is lowered and pressure is supplied at the set
level. The squeegee unit moves forwards, during which time printing takes
place on the PCB. After printing is completed, the table moves down and
out. The rear squeegee is raised and the front squeegee is lowered. The
squeegee unit moves to the rear, during which time flooding of the stencil
takes place.
Screen printing mode 2
After the foot switch is pressed, the table moves into the print area and is
raised. The rear squeegee is lowered and pressure is supplied at the set
level. The squeegee unit moves forwards, during which time printing takes
place on the PCB. After the first printing process the table remains in posi-

squeegee unit moves to the rear. During this time the stencil is flooded.
After flooding is completed the flooding squeegee is raised, and the rear
squeegee is lowered and pressure is supplied at the set level. The same
printing procedure takes place again. After the second printing process, the
table is moved down and out. The rear squeegee is raised and the front
squeegee is lowered. The squeegee unit moves to the rear, during which
time flooding of the stencil takes place.
Stencil printing mode 3
Stencil printing is carried out with a steel squeegee. After the foot switch is
pressed, the table moves into the print area and is raised. The rear squee-
gee is lowered and pressure is supplied at the set level. The forward print-
ing process is carried out. After this, the rear squeegee is raised and the
front squeegee is lowered. The squeegee unit moves to the rear and a
