High Flow Table Vacuum Controls
NOTE
The number of active pumps, the level of venting, and media characteristics affect the level of
vacuum required to secure the media to the table. It is up to the operator to determine the level
of vacuum sufficient to draw down and secure media to the vacuum table without having a
negative effect on print quality.
Masking the Vacuum Table
If your media does not cover all of the vacuum table you must mask all of the area around the
media to create a closed vacuum system. Use scrap media or non-porous material that is less
than the thickness of the media to mask the table. The masking material must be inserted under
the edge of the media with an overlap of between 5 to 25 mm (.2 to .5 inches)
NOTE
If there is no overlap or a gap between the media and the masking material, ink may be
deposited on the table around the media edge.
Maintaining the Vacuum Table
If ink build-up occurs on the table, remove the ink. If it is not removed, the print gap can be
affected and this may affect the vacuum table's ability to secure the media properly. To remove
ink we recommend that you use a paint scraper containing a straight edge razor blade.
