FORMATION OF DETECTION REGIONS BY DETECTOR MODULES COUPLED TO A MOVABLE CARRIAGE

摘要

A printing apparatus includes a carriage, a first detector module, and a second detector module. The carriage may selectively move a fluid applicator along a scanning path in a first scanning direction and a second scanning direction across a print zone to print on a media therein. The first detector module and second detector module may be coupled to the carriage. Further, the first detector module may include a first receiver and a first source to form a first detection region there between downstream of the carriage in the first scanning direction to detect an object therein. The second detector module may include a second receiver and a second source to form a second detection region there between downstream of the carriage in the second scanning direction to detect an object therein.

1. A printing apparatus, comprising:
a carriage to receive a fluid applicator and to selectively move the fluid applicator along a scanning path in a first scanning direction and a second scanning direction across a print zone to print on a media therein, the carriage having a carriage surface disposed to face the print zone; a first detector module and a second detector module coupled to the carriage;
the first detector module including a first receiver and a first source to form a first detection region there between downstream of the carriage in the first scanning direction to detect an object therein; andthe second detector module including a second receiver and a second source to form a second detection region there between downstream of the carriage in the second scanning direction to detect an object therein; and wherein the first source, the second source, the first receiver, and the second receiver are disposed outside of the print zone.
