Abstract
Apparatus for automatically feeding and rolling output media from a printer. The apparatus comprises a supply roll for supplying a recording media having a leading edge, a clamping assembly for clamping the leading edge of the recording media, the clamping assembly also supplying a surface for the media to roll thereon. The apparatus further comprises an assist drive roller assembly for driving the leading edge of the recording media into the clamping assembly, a differential drive assembly for driving the clamping assembly to allow the recording media to be rolled thereon, and a retract assembly for retracting the clamping assembly to allow the clamping assembly to be removed from the recording media, after the media has been rolled onto the clamping assembly, causing the recording media to drop.
Claims10
An apparatus for automatically feeding and rolling output media from a printer, comprising:
- supplying mechanism for supplying a recording media having a leading edge;
- clamping mechanism for clamping side portions of said leading edge of said recording media, said clamping mechanism securing said media when clamped and releasing said media when unclamped, said clamping mechanism having a first circumferential surface when said clamping mechanism is clamped and a second circumferential surface when said clamping mechanism is unclamped;
- first driving mechanism for driving said leading edge of said recording media into the interior of said clamping mechanism;
- second driving mechanism for driving said clamping mechanism to allow said recording media to be rolled onto said first circumferential surface of said clamping mechanism;
- and
- retracting mechanism for removing said clamping mechanism from the interior of said recording media after said media has been rolled onto said clamping mechanism, causing said recording media to be unsupported.
A method for automatically feeding and rolling output media from a printer, including the steps of:
- supplying a recording media having a leading edge;
- driving said leading edge of said recording media into the interior of a clamping device, said clamping device securing said media when clamped and releasing said media when unclamped, said clamping device having a first circumferential surface when said clamping device is clamped and a second circumferential surface when said clamping device is unclamped;
- clamping side portions of said leading edge of said recording media;
- driving said clamping device to allow said recording media to be rolled onto said first circumferential surface of said clamping device;
- rolling said recording media onto said first circumferential surface of said clamping device;
- cutting said recording media;
- unclamping said clamping device releasing said leading edge of said recording media;
- and
- retracting said clamping device and removing said clamping device from the interior of said recording media allowing said recording media to be unsupported.
