Adjust the settings by checking the rolling state.
Press the [Stop] button in the Rolling dialog box to temporarily stop the rolling operation, and enter the
optimum values in the Squeegee Pressure and Squeegee Speed parameters.

NOTE
Set the Squeegee Speed and Squeegee Pressure parameters by checking how solder on the mask is scraped during
rolling operation. If the solder is not sufficiently scraped, increase the squeegee pressure and reduce the squeegee
speed. But, note that an excessive squeegee pressure level will cause the solder to spread beyond the required area
or will scrape away the solder too much.

TIP
When the "Cleaning Method" parameter (on the [Print]-[Cleaner] tab) is set to "Auto", the mask is automatically
cleaned every time that the specified number of boards has been produced (or at specified time intervals). To stop
production during automatic operation, press the [STOP] key on the operation panel. If you want to stop production
