Printer incorporating a sheet displacement mechanism having an array of spaced apart nozzles
View Patent ↗A printer includes a support structure. A feed arrangement is positioned on the support structure and is configured to feed an endmost sheet of print media from the stack. The feed arrangement includes a movable pick-up assembly, the pick-up assembly having an array of spaced apart nozzles configured to direct air on to respective locations along said topmost sheet so that said topmost sheet can be picked-up from the stack by moving said pick-up assembly. A pair of rollers is configured to engage with said endmost sheet fed from said feed arrangement. A printing station is configured to print ink upon said endmost sheet engaged by said rollers. An air displacement mechanism is connected to the nozzles to displace air out of some expulsion nozzles and into some other suction nozzles.
1. A printer comprising:
a support structure;
a feed arrangement positioned on the support structure and configured to feed an endmost sheet of print media from the stack and including a movable pick-up assembly, the pick-up assembly having an array of spaced apart nozzles configured to direct air on to respective locations along said topmost sheet so that said topmost sheet can be picked-up from the stack by moving said pick-up assembly;
a pair of rollers configured to engage with said endmost sheet fed from said feed arrangement;
a printing station configured to print ink upon said endmost sheet engaged by said rollers; and
an air displacement mechanism connected to the nozzles to displace air out of some expulsion nozzles and into some other suction nozzles, wherein
said array consists of a one dimensional array.
2. A printer as claimed in claim 1 , wherein the air displacement mechanism includes an air pump in fluid communication with the expulsion nozzles.
3. A printer as claimed in claim 1 , wherein one of said rollers is a drive roller and the other one of said rollers is a driven roller.
