An ink jet recording device is disclosed, comprising: recording heads for ejecting ink and printing on recording media; a carriage member having said recording heads and moving reciprocatingly between a printing region and a non-printing region; and a cleaning member for cleaning a (front) surface, which has nozzles, of said recording heads by contacting with said surface when said carriage member enters said non-printing region, and said cleaning member moving to a position at which said cleaning member is capable of contacting with said surface, which has said nozzles, of said recording heads, linking with a movement, which is for entering said non-printing region, of said carriage member, and moving to a position at which said cleaning member does not contract with said surface, which has said nozzles, of said recording heads, linking with the passage of an engaging portion of carriage side at a position of a projecting engaging portion of blade holder side when said carriage member is moved from said non-printing region to said printing region.
An ink jet printer capable of easily controlling a wiping unit, or cleaning unit, by use of driven members that pivot when they come into contact with a carriage. The ink jet printer is provided with first and second driven members that are disposed in association with a travel path of the carriage. The driven members selectively project into the travel path of the carriage. As a result of the carriage coming into contact with the first driven member, a wiper member moves to a projected position. As a result of the carriage's further movement toward the second driven member, the wiper member wipes a nozzle surface of a print head. Further, as a result of the carriage moving toward the second driven member, the wiper member wipes the nozzle surface of the print head. As a result of the carriage coming into contact with the second driven member, the wiper member moves to a standby position.
A dual pivoting wiper system cleans the nozzle face plate of an inkjet printhead, particularly one that dispenses a pigment based ink. An inkjet printing mechanism has a printhead service station including a sled that moves from a rest position to a wiping position. The wiping system includes a support arm with proximate and distal ends, with the proximate end pivoted to the sled and the distal end pivotally supporting an upright wiper blade. The arm is spring-biased to push the wiper blade into engagement with the printhead. During wiping, the printhead is engaged by wiper blade and the blade remains relatively upright. Any spacing variations between the printhead and the sled are accommodated by spring flexure, and any lack of parallelism of the printhead from a nominal plane is primarily accommodated by pivoting of the blade at the distal end of the support arm.
An ink jet printer has a recovery system for restoring the function of the ink nozzles during a standby mode of the ink head. The recovery system includes a wiper for wiping the nozzle surface of the ink head and cap members for capping the nozzles for ink absorption operation, both driven by the movement of the ink head assembly. The ink head assembly first moves in the first direction from the operational area to the standby area to cap the nozzles by the cap members, moves in the opposite direction to wipe the nozzle surface using the wiper, moves again in the first direction for ink purging, and then returns to the operational area.
Apparatus for cleaning the nozzles of an ink jet cartridge that is mounted upon the carriage of a small point of sale printer. The carriage is arranged to carry one or more ink cartridges over a reciprocal path of travel through a printing station. The printer contains a drive roller mounted upon a shaft for advancing a substrate through the printing station. A rotor is journalled for free rotation on the shaft adjacent to one end of the drive roller. A rocker arm connects the rotor to a solenoid which when energized moves the rotor from an inoperative position into an operative position. A wiper blade is mounted upon the rotor which is adapted to wipe the nozzles on the ink cartridge when the rotor is in the operative position and to retract the blade out of contact with the nozzles when the rotor is moved into the inoperative position.
An ink-jet recording apparatus includes: an ink-jet recording head; a carriage on which the ink-jet recording head is mounted, the carriage being capable of traveling between a printing and a non-printing area, the carriage having an operating lever on non-printing area thereof; and a wiper for wiping the ink-jet recording head in the non-printing area, the wiper having a projected piece including two tilted sides, the tilted sides being projecting toward the passage in which the carriage moves when the wiper is set in position where the wiper is capable of wiping, wherein, while the carriage is moved in the directions of printing and non-printing area of the carriage, the operating lever comes in contact with the projected piece of the wiping lever so as to move the wiping means out of the traveling passage of the carriage.
