Print head pressure detection and adjustment
First Claim
1. A system, comprising:
- a print station having an opening for receiving print medium traveling along a transport pathway, the print station including an adjustable print head assembly;
a medium dispenser for transporting the print medium on the transport pathway to the print station;
a medium width sensor configured to detect the width of the print medium on the transport pathway;
a pressure sensor arrangement positioned on the transport pathway, wherein the pressure sensor arrangement is configured to detect pressure imposed by the print head assembly at a plurality of points along the width of the transport pathway;
a monitoring subsystem comprising a central processing unit and memory in communication with the medium width sensor and the pressure sensor arrangement; and
a network connecting the monitoring subsystem to a remote device having a display;
wherein the monitoring subsystem includes a program configured to calculate, based at least in part upon the detected width and the detected pressure, amounts of pressure imposed by the print head assembly at points along the width of the print medium;
wherein the remote device is configured to provide visual feedback to a user including the amounts of pressure imposed by the print head assembly along the width of the print medium;
wherein the monitoring subsystem is configured to continuously monitor the output of the medium width sensor and the pressure sensor arrangement when a series of images are printed; and
wherein the monitoring subsystem is configured to provide an alert to the remote device if the amount of pressure changes during printing of the series of images.

Abstract
A printing system includes a print station for receiving print medium traveling along a transport pathway and an adjustable print head assembly. A medium dispenser transports the print medium on the transport pathway to the print station, and a medium width sensor detects the width of the print medium. A pressure sensor arrangement detects pressure imposed by the print head assembly at points along the width of the transport pathway when an image is printed on the print medium. A monitoring subsystem in communication with the medium width sensor and the pressure sensor arrangement calculates, based upon the detected width and the detected pressure, amounts of pressure imposed by the print head assembly along the width of the print medium.
