Vacuum platen assembly for fluid-ejection device with anti-clog vacuum hole sidewall profiles

A vacuum platen assembly for a fluid-ejection device comprising:

• a platen;
• a plurality of ribs extending from the platen;
• and,
• means for providing suction effect to maintain positioning of media against the plurality of ribs by suction effect substantially without suction-impairing collection of at least one of:
• dust particles, media debris, and aerosol.

A fluid-ejection device comprising:

• a fluid-ejection mechanism ejecting fluid towards media, ejection of the fluid resulting in dispersal of aerosol;
• a vacuum platen having a plurality of vacuum holes;
• and,
• a plurality of ribs extending from the vacuum platen, against which positioning of the media is maintained during operation by suction effect from the plurality of vacuum holes, while the media moves over the vacuum platen, resulting in media debris,
• each of at least one of the plurality of vacuum holes having sidewalls with profiles at least substantially prevent collection of the media debris and the aerosol on the sidewalls.

A method comprising:

• moving media past a plurality of ribs of a platen, resulting in media debris;
• suctioning media against the plurality of ribs while the media moves past the platen, utilizing a plurality of vacuum holes through the platen, each hole having non-parallel sidewalls;
• and,
• ejecting fluid towards the media, resulting in dispersal of aerosol.

A vacuum platen assembly for a fluid-ejection device comprising:

• a platen having a plurality of vacuum holes,
• each of at least one of the plurality of vacuum holes having sidewalls with anti-clog profiles to at least substantially prevent collection of media debris and aerosol on the sidewalls,
• wherein the sidewalls of each of the at least one of the plurality of vacuum holes are one or more of:
• non-parallel sidewalls, non-straight sidewalk, and tapering sidewalls.
