Abstract
A multi-carriage printing device has a first member, a first bar mounted on the first member, and a first printer carriage mounted on the first bar. The device further has a second bar mounted on the first member, a second printer carriage mounted on the second bar, and a first temperature sensor positioned to sense a first temperature of the member.
Claims15
A multi-carriage printing device, comprising:
- a first member;
- a first bar mounted on the first member;
- a first printer carriage mounted on the first bar;
- a second bar mounted on the first member;
- a second printer carriage mounted on the second bar;
- a first temperature sensor positioned to sense a temperature of the first member;
- and
- logic configured to calculate a reference position of the first carriage and a position of the second carriage relative to the first carriage based upon the temperature of the first member such that a first swath printed by the first carriage substantially aligns with a second swath printed by the second carriage.

A method, comprising:
- storing data indicative of a first temperature of a member, the member coupling a first carriage to a second carriage;
- receiving a signal indicative of a second temperature of the member from a temperature sensor;
- calculating when the second carriage prints relative to the first carriage based upon the first temperature and the second temperature.
A multi-carriage printing device, comprising:
- a first member;
- a first bar mounted on the first member;
- a first printer carriage mounted on the first bar;
- a second bar mounted on the first member;
- a second printer carriage mounted on the second bar;
- a first temperature sensor positioned to sense a temperature of the first member;
- and
- logic configured to adjust when a print head of the second carriage prints an image based on a signal received from the first temperature sensor indicative of the temperature of the first member.
