The methods may include methods that may, at least in part, be implemented at a printer including tracking one or more locations of a scan device with respect to a sheet having a first one or more pictures associated with one or more corresponding images, wherein the tracking is based, at least in part, on electronic data provided by the scan device. The printer may then based at least in part on the tracking, execute at least one operation in connection with all or a selected subset of the one or more corresponding images.

Abstract: A printer system includes a print head assembly that ejects a printing solution from a fixed position during a print period and a conveying mechanism operable to convey an operations assembly. The operations assembly executes servicing functions on the print head assembly during a non-print period. Furthermore, the print head assembly remains in the fixed position during the non-print period and the operations assembly provides support for a print medium during the print period.

The novel systems may include, among other things, a print and a scan mechanism having a common input path to receive a first and a second media, the first media being original media to be scanned by the scan mechanism, and the second media being blank media to be printed on by the print mechanism. The system may further include a divider and a first sensor. The divider being configured to provide to the common feed path the first and the second media by defining a first and a second input slot to locate the first and the second media, respectively, wherein the divider to provide the first and the second media to the common feed path via the first and second input slots. The first sensor may detect absence of the first media in the first input slot.

Abstract: A multi-function printer having a compact size and portable configuration while providing printing, scanning and copying functionalities is disclosed herein. The multi-function printer includes a printer assembly and a scanner assembly configured to cooperatively utilize the same pick and paper movement systems along a common feed or paper path to perform these printing, scanning and copying functions. Thus, the disclosed multi-function printer may require a less complex paper movement and control system which, in turn, reduces the printer's overall weight while increasing its flexibility and/or portability.

Abstract: The velocity of a printhead scanning across a sheet of paper or other print medium is varied on the basis of whether masking patterns for selectively activating nozzle of the printhead include activations in consecutive pixel locations of the masking pattern. The pixel locations are “firing opportunities” as defined by the maximum firing frequency assigned to the nozzles when the printhead is scanned at a particular velocity. The printhead is moved at that velocity when a masking pattern includes activation in consecutive pixel locations. On the other hand, a higher scanning velocity is available when a constraint is enforced to prevent occasions of firings in consecutive pixel locations. In one embodiment, the constraint is not enforced, but masking patterns are analyzed on a pattern-by-pattern basis to detect those patterns which satisfy the constraint, so that the scanning velocity can be increased during the suitable masking patterns.
