Abstract
Separator assembly for use with printers is described herein. One example separator assembly includes a separator pad movable between a first position and a second position such that the separator pad is to engage a leading edge of a print media in the second position. A cam is rotatable between a third position and a fourth position to move the separator pad from the first to the second position.
Claims23
A separator assembly comprising
- a separator pad moveably coupled to a guide ramp, the separator pad having a first position in which a surface of the separator pad protrudes a first distance within a media path relative to the guide ramp, the surface of the separator pad to deflect to a second position relative to the guide ramp and away from the media path when a print media engages the separator pad;
- an actuator to engage the separator pad to move the surface of the separator pad to a third position in which the surface of the separator pad protrudes a second distance into the media path relative to the guide ramp, the first distance being less than the second distance;
- and
- a separator roller coupled to the actuator, the separator roller to frictionally engage a drive roller of a feed mechanism, and the separator roller to disengage the drive roller when the actuator is rotated relative to a base between respective first and second positions.

A separator assembly comprising:
- a separator pad disposed within a media path of a printing apparatus, the separator pad deflectable relative to a base;
- an actuator rotatably coupled relative to the separator pad, rotation of the actuator to cause the separator pad to move further into the media path to move leading edges of print media away from the separator pad subsequent to a top sheet being transported to a print zone, wherein the actuator is activated via a service sled of the printing apparatus;
- and
- a pad backer disposed between the separator pad and the actuator, the pad backer movably coupled relative to the separator pad.

A separator assembly comprising:
- a separator pad disposed within a media path of a printing apparatus, the separator pad deflectable relative to a base;
- an actuator rotatably coupled relative to the separator pad, rotation of the actuator to cause the separator pad to move further into the media path to move leading edges of print media away from the separator pad subsequent to a top sheet being transported to a print zone;
- a pad backer disposed between the separator pad and the actuator, the pad backer movably coupled relative to the separator pad;
- and
- a service sled to engage a lever to activate an actuation arm and a cam, the cam is to engage the pad backer to move the pad backer toward the separator pad such that the separator pad further moves into the media path to reset a leading edge of print media relative to the separator pad.

A separator pad assembly comprising:
- a separator pad moveably coupled relative to a guide ramp between a first position and a second position, the separator pad having a surface dimensioned and positioned to protrude a first distance within a media path relative to the guide ramp to separate a first print media sheet from a plurality of print media sheets when the separator pad is in the first position, the surface of the separator pad structured and dimensioned to deflect to a deflected position relative to the guide ramp and away from the media path in response to engagement of the first print media sheet with the separator pad;
- and
- an actuator structured and positioned to engage the separator pad to move the surface of the separator pad to the second position in which the surface of the separator pad protrudes a second distance into the media path relative to the guide ramp, the first distance being less than the second distance, the separator pad being dimensioned to engage a leading edge of the plurality of print media sheets when the separator pad enters the second position to move the leading edge away from the separator pad after the first print media sheet has been separated from the plurality of print media sheets, wherein the separator pad is free to slide relative to the guide ramp without interference from the actuator when the first print media sheet engages the separator pad.
A separator assembly comprising:
- a separator pad moveably coupled relative to a guide ramp to move between a first position and a second position, the separator pad having a surface dimensioned and positioned to protrude a first distance within a media path relative to the guide ramp to separate a first print media sheet from a plurality of print media sheets when the separator pad is in the first position, the surface of the separator pad structured and dimensioned to deflect to a deflected position relative to the guide ramp and away from the media path in response to engagement of the first print media sheet with the separator pad;
- a pad backer disposed on the separator pad;
- and
- an actuator having a cam structured and positioned to move along a surface of the pad backer on the separator pad to move the surface of the separator pad to the second position in which the surface of the separator pad protrudes a second distance into the media path relative to the guide ramp, the first distance being less than the second distance, the separator pad being dimensioned to engage a leading edge of the plurality of print media sheets when the separator pad enters the second position to move the leading edge away from the separator pad after the first print media sheet has been separated from the plurality of print media sheets, the actuator to move the separator pad from the deflected position to the second position, and the actuator to release the separator pad to enable the separator pad to move from the first position to the deflected position.

A separator assembly comprising:
- a separator pad to be positioned within a media path of a printing apparatus, the separator pad structured and dimensioned to deflect relative to a base to separate a first print media from a second print media;
- an actuator rotatably coupled to the separator pad, rotation of the actuator to move the separator pad further into the media path to move a leading edge of the second print media away from the separator pad subsequent to first print media being separated from the second print media and transported to a print zone;
- and
- a pad backer positioned between the separator pad and the actuator, the pad backer being slidably coupled to the separator pad to enable the separator pad to slide relative to the pad backer when the separator pad deflects relative to the base to separate the first print media from the second print media.
