Closed-loop printing registration systems, devices, components and methods
First Claim
1. A method of registering a sheet of paper in a printer, comprising:
- aligning at least one of an edge or a corner of a sheet of paper with at least portions of one or more permanent invisible ink markers disposed on, in or under a platform located beneath or above the sheet;
aligning at least portions of a sensor assembly with one or more of at least portions of the one or more permanent invisible ink markers and at least portions of one or more invisible ink landmarks that have previously been dispensed on the sheet, anddispensing a plurality of invisible ink paper registration landmarks onto the sheet of paper in response to the sensors detecting at least one of at least some of the permanent invisible ink markers and at least some of the invisible ink landmarks.

Abstract
Closed-loop printing registration systems (e.g., printers), devices, components and methods are provided. In one embodiment, a printer reproduces continuously and sequentially on a sheet of paper invisible ink landmarks that mimic registration information provided initially by permanent invisible ink markers disposed on a platform or platen. According to one embodiment, once the first row of invisible ink landmarks has been printed on a sheet of paper, the first and subsequent rows of invisible ink landmarks provide a basis for continuous registration and alignment of sheet of the paper as it is being printed upon and advanced through the printer. In other embodiments, one or two invisible ink landmarks dispensed on a sheet of paper, preferably in combination with a sensed edge or corner of a sheet of paper, provide sufficient information for a sheet of paper to be registered and aligned initially with respect to a print head or carriage, and for subsequent invisible ink landmarks to be deposited on the sheet of paper at locations which are determined.
