A method and system sense print a calibration feature towards an edge of a medium, scan the feature to determine a parameter and adjust a characteristic of the scanner based on the parameter.

Scanner characteristic adjustment

In one embodiment, a media handling system is provided to transfer media through an image forming device having a primary media path and a duplex media path. The media handling system includes a media feeder configured to input media into the duplex media path of the image forming device.

System and method for handling print media

A method is disclosed for generating a calibration target on a medium. The method can include the operation of inserting the medium into a printer with a first orientation. A further operation can be printing a first calibration feature at a first lateral location on the medium. Another operation can be reinserting the medium into the printer with a second orientation rotated 180 degrees from the first orientation. A second calibration feature can be printed at a second lateral location on the medium.

Method and apparatus for generating a calibration target on a medium

A multifunction printer apparatus includes a printer, with a printer media path, and a scanner/stapler assembly detachably secured to the printer. The scanner/stapler assembly includes a scanner and a stapler-configured media path that begins at the printer media path and emerges from the scanner/stapler assembly along a direction perpendicular to a feed direction of the scanner.

Multifunction printer with integrated scanner/stapler

When a printer is connected to conventional office power, i.e.. 110 VAC service, it automatically operates in &ldquo;slowdown-capable&rdquo; mode. In such a &ldquo;slowdown-capable&rdquo; mode, as the printer works harder, it may slow down and reduce performance when there is not enough energy available from the input power source. When the same printer is connected to 220 Volt (or higher) service, it automatically senses this higher input power availability and allows the printer to draw more power from the input, always operating at its highest performance mode to complete the jobs as efficiently as possible. Thus, the printer operates at its highest performance level taking in to consideration the minimum amount of power available and amount of power necessary.

Office printer with automatic input power sensing and variable throughput speed

An electronic printer having wireless power and communications connections to accessory units to which it is adjacent and with which it is in contact during operation is disclosed. Communications between the printer and the accessory unit, instead of being handled via a cable connection, are achieved using a two-way, infrared (IR) communications link. Power is supplied to the accessory via inductive coupling rather than directly through power cables. As inductive coupling works efficiently only over very short distances, the accessory unit is equipped with a standby battery power so that the accessory may be temporarily separated from the printer (e.g., in order to eliminate media jams) without loss of accessory status data. When the accessory is once again positioned immediately adjacent the printer, the inductive coupling reassumes the role of power provision. The invention eliminates problems associated with cable connections, such as the inadvertent disconnection of a power or communication cable, damage to connectors over the operational lifetime of the printer and its accessory, as well as manufacturing and stocking costs associated with the connector cables.
