8. Rolling operation
In rolling operation, the squeegee head moves back and forth repeatedly in order to roll and agitate solder
on the mask until it becomes suitable for printing. Rolling operation is recommended in cases where you first
print after supplying solder on the mask or when solder has been left on the mask for a long time while not in
operation.

NOTE
The board surface becomes soiled during rolling operation, so we recommend covering the board surface with a
transparent sheet (available as option). After rolling operation, clean the backside of the mask by automatic or
manual cleaning.
