Abstract
It is hereby disclosed a carriage arrangement for lubricating a carriage, wherein the arrangement comprises: a carriage; a carriage beam; a drive mechanism to move the carriage along a longitudinal direction of the carriage beam; and a lubrication roller at a fixed position relative to the carriage beam, the lubrication roller having an outer surface with a non-lubricating section and a lubricating section each at a determined angular position; wherein the carriage is to contact the outer surface as it moves passed the lubrication roller and wherein the contact causes a rotation of the roller that modifies the angular positions of the lubricating section and the non-lubricating section.
Claims15
A carriage arrangement comprising:
- a carriage;
- a carriage beam;
- a drive mechanism to move the carriage along a longitudinal direction of the carriage beam;
- and
- a lubrication roller at a fixed position relative to the carriage beam, the lubrication roller having an outer surface with a non-lubricating section and a lubricating section each at a determined angular position;
- wherein the carriage is to contact the outer surface as it moves passed the lubrication roller and wherein the contact causes a rotation of the roller that modifies the angular positions of the lubricating section and the non-lubricating section.
A printing system comprising:
- a carriage beam;
- a print medium support;
- a carriage to slide along the carriage beam and extending over the print medium support,
- a lubrication roller fixed at a position along the carriage beam wherein the lubrication roller comprises an outer surface with a non-lubricating section or a lubricating section extending longitudinally along the lubrication roller at a determined angular position;
- and
- wherein the carriage reciprocates along the carriage beam and, upon contact with the lubrication roller rotates modifying the determined angular position of the lubricating section.
A lubrication method of a carriage beam in a printing system comprising a carriage associated to the carriage beam and a lubrication roller in contact with the carriage beam as to apply a lubricant while moving along the carriage beam, the lubrication roller having lubricating and non-lubricating sections extending longitudinally along an outer surface of the lubrication roller and the method comprising:
- move the carriage towards the lubrication device,
- causing a rotation of the lubrication roller by contacting in a first direction;
- and
- move the carriage in a second direction opposite to the first direction contacting the lubrication roller,
- wherein the lubrication roller is to contact the carriage with a lubricating section or a non-lubricating section in the first and the second direction and to modify an angular position of the lubricating section and the non-lubricating section upon contact with the carriage in the first and/or the second direction.
