Perforation forming mechanism for use in an imaging apparatus
View Patent ↗An apparatus for perforating a sheet of media includes a perforation forming mechanism including at least one perforation device. The perforation forming mechanism is configured to drive the perforation device through the sheet of media to extend through the sheet of media by a distance.
1. An apparatus for perforating a sheet of print media having a front side and a back side, comprising:
a printhead carriage for carrying a printhead;
a perforator carriage for carrying a perforation forming mechanism, wherein said perforation forming mechanism includes a perforation device;
an isolation damper coupling said printhead carriage to said perforator carriage; and
a perforation maintenance station including an abrasive member for sharpening said perforation device at a location outside of a perforation zone of said perforation device.
2. An apparatus for perforating a sheet of print media having a front side and a back side, comprising:
a printhead carriage for carrying a printhead;
a perforator carriage for carrying a perforation forming mechanism;
an isolation damper coupling said printhead carriage to said perforator carriage; and
a controller coupled to said perforation forming mechanism, said controller being configured to select at least one of a vertical perforation resolution and a horizontal perforation resolution of said apparatus.
3. An apparatus for perforating a sheet of print media having a front side and a back side, comprising:
a printhead carriage for carrying a printhead;
a perforator carriage for carrying a perforation forming mechanism;
an isolation damper coupling said printhead carriage to said perforator carriage;
a D-shaped guide rod for guiding said printhead carriage and said perforator carriage, said D-shaped guide rod being drivingly coupled to said perforation forming mechanism;
a motor coupled to said D-shaped guide rod; and
a controller connected to said motor, said controller being configured to operate said motor so as to impart a rotation to said D-shaped guide rod to drive said perforation forming mechanism.
