Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.

An image scanner includes a main body and a lid. The main body includes a scan window. The scan window is covered by the lid when the lid is closed and is exposed when the lid is open. A lid position detector detects whether the lid is open or closed.

Lid position detector for an image scanner

A scanner is disclosed. The scanner has a scan sensor with a width smaller than the width of the platen. The scanner scans a first pass of the platen with the scan sensor in a first position on one side of the platen. The scanner then moves the scan sensor to the other side of the platen and does a second pass.
