Abstract
Several embodiments of apparatus and methods are disclosed. One or more of the disclosed example devices includes a flexible member having first and second tensioning members.
Claims23
A device, comprising:
- a belt;
- a carriage;
- a first tensioning member disposed between the carriage and the belt;
- a second tensioning member disposed between the carriage and the belt;
- the first and second tensioning members configured to tension the belt, wherein the first and second tensioning members comprise springs, each of the first and second springs having a first end coupled to the carriage and a second end coupled to the belt, wherein the first and second tensioning members are configured to filter out vibration frequencies in the belt during operation;
- a first pulley;
- a second pulley spaced a fixed distance from the first pulley, wherein the belt is disposed around the first and second pulleys and wherein the carriage is coupled to the belt via the tensioning members such that the tensioning members tension the belt about the first and second pulleys;
- and
- an inkjet printhead at the carriage, wherein the carriage has a mass in the range of 20 grams to 1000 grams, wherein the belt has a tension in the range of 1 to 25 Newton and wherein the first tensioning member and the second tensioning member each have a spring rate in the range of 0.1 to 7.5 Newton/mm.
