PRINT MEDIA FLIPPING MECHANISM AND METHOD
Abstract:
A method for flipping over a printing media (102), comprising: a) capturing the printing media in a nip between a driver roller (108) and a pinch roller (110); b) turning the driver roller (108) while holding at least a leading portion of the printing media (102) against the driver roller, so that the printing media (102) moves forward around the driver roller; c) releasing the leading portion of the printing media (102) from the driver roller (108); d) changing the forward velocity of the leading portion of the printing media (102), while the driver roller (108) continues to move a trailing portion of the printing media (102) caught in the nip forward, thereby causing the paper to buckle away from the driver roller; e) releasing the trailing portion of the printing media (102) from the nip; and f) allowing the trailing portion of the printing media (102) to fall freely so that it ends up in a flipped over orientation.
