Abstract
In one example, a system to convey print media through a print zone in a printer includes an endless conveyor belt in a loop, a pair of drivers to circulate the conveyor belt through the print zone from opposite ends of the loop, an encoder to measure movement of the conveyor belt, and a controller programmed to control both drivers driving the conveyor belt based on measurements from the encoder.
Claims13
A system to convey print media through a print zone in a printer, the system comprising:
- an endless conveyor belt in a loop;
- a pair of drivers to circulate the conveyor belt through the print zone from opposite ends of the loop;
- an encoder unit located under the conveyor belt, and directly connected to the conveyor belt at, and in, the print zone, to measure movement of the conveyor belt in the print zone;
- and
- a controller programmed to control both drivers driving the conveyor belt based on measurements from the encoder unit.
A system to convey print media through a print zone in a printer, the system comprising:
- an endless conveyor belt in a loop;
- a pair of pulleys to circulate the conveyor belt through the print zone from opposite ends of the loop;
- a pair of motors to turn the pulleys;
- an encoder unit directly connected to the conveyor belt under, and at, the print zone, with an encoder in the print zone to measure movement of the conveyor belt in the print zone;
- and
- a controller programmed to control both motors based on movement measured by the encoder.
A process for circulating an endless belt in a loop, comprising:
- an encoder unit directly connected to the belt at a print zone;
- a first pulley pulling forward on an upper run of the belt from one end of the loop;
- a second pulley simultaneously pulling back on a lower run of the belt from the other end of the loop;
- and
- both pulleys pulling the respective run of the belt at the same linear speed.
