High Accuracy or High Speed Printing Services

Accuracy and resolution are two aspects generally considered when it comes to printer quality. With PixArt's advanced sensor chip solution, we are able to deliver both to the highest standard.

PixArt's Optical Tracking Sensor (OTS) for printing devices helps to track paper travelling distance from the non-printing-side of the printing papers or photographic papers, and improve printing speed and image quality through its exceptionally accurate paper-alignment capability. The OTS product comes in a highly integrated module that includes a light source, an optical chip and a lens to facilitate further assembly works. The module is designed to directly track paper media to detect its alignment and feeding parameters for the best printing result.

In order to meet accuracy requirements, the error rate of the module is designed to be as low as +/-0.015mm for over 25mm travel distance, which is equal to merely 0.06%. The module tolerates a media lift height (paper floating distance) of +/-0.05mm, indicates that any paper movement within the range is detectable by the sensor. In terms of resolution, PixArt offers a high resolution of up to 17904cpi that allows the module to precisely identify and report on the slightest paper shift. The detection speed can vary according to customers' application requirements, with the highest being 150ips.

The innovative OTS technology of PixArt has so far delivered a variety of meticulous solutions to our A-list printing customers to enhance their series of compact and media/multi-function printers. The same technological concept can also be applied to optimize the auto-feeding function for scanners, money exchange machines and currency detectors.
