Abstract
Systems and methods are provided for predictively compensating for frequency-based shifts of the position of a web of print media in a continuous-forms printer. The system comprises a sensor and a controller. The sensor is able to detect lateral shifts of the web of print media traveling through the continuous-forms printer. The controller is able to identify a frequency of the lateral shifts of the web, and to steer the web based on the frequency.
Claims24
A system comprising:
- a sensor operable to detect lateral shifts of a web of print media traveling through a continuous-forms printer;
- and
- a controller operable to identify a frequency of the lateral shifts of the web, and to steer the web based on the frequency.
A method comprising:
- detecting lateral shifts at a web of print media traveling through a continuous-forms printer;
- identifying a frequency of the lateral shifts of the web;
- and
- steering the web based on the frequency.
A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:
- detecting lateral shifts at a web of print media traveling through a continuous-forms printer;
- identifying a frequency of the lateral shifts of the web;
- and
- steering the web based on the frequency.
