An imaging apparatus includes a frame and a maintenance sled movably coupled to the frame. The maintenance sled includes a carrier engagement member. A printhead carrier is coupled to the frame. A carrier motor is drivably coupled to the printhead carrier. A controller is coupled to the carrier motor. The controller controls the carrier motor to drive the printhead carrier at a first velocity and at a second velocity. The second velocity is lower than the first velocity. The printhead carrier is controlled to move at the first velocity toward the maintenance sled, wherein prior to the printhead carrier contacting the carrier engagement member of the maintenance sled, the printhead carrier is decelerated from the first velocity to the second velocity.

A method of performing printhead maintenance firing in an ink jet printer that has a printhead carrier that carries an ink jet printhead, the ink jet printer having a waste ink receptacle, includes the steps of decelerating the printhead carrier from a first velocity after printing print data; and controlling a firing of the printhead during the decelerating in accordance with maintenance data so that ink droplets ejected from the printhead during the decelerating are received by the waste ink receptacle.

An imaging apparatus includes a housing having a cartridge exchange opening, and a printhead carrier system contained in the housing. The printhead carrier system has a printhead carrier. A cover is pivotably attached to the housing. The cover has an engagement surface. When the cover is in a closed position the cartridge exchange opening is not exposed. A switch unit has a switch actuator and a switch. The engagement surface of the cover is positioned to engage the switch actuator when the cover is in the closed position. The switch actuator is configured with a button that is accessible by a user to facilitate manual manipulation of the switch actuator by a force applied to the button by the user. The printhead carrier is positioned based on an output of the switch.

A printhead capping assembly includes a cap holder and a printhead cap. The cap holder defines a cavity and a vent exit. The printhead cap has a base and a lip portion extending from the base. The lip portion defines an open interior region. The base is inserted into the cavity of the cap holder. The base includes a serpentine channel extending from the open interior region to the vent exit of the cap holder.

A printhead capping assembly includes a cap holder, a printhead cap and a pin. The pin includes a head and a shaft. The shaft has a proximal end and a distal end, with the proximal end being adjacent to the head. The head has an outer periphery, and a bottom surface extending outwardly from the shaft toward the outer periphery. The pin has a channel including a first channel portion and a second channel portion. The first channel portion extends from the outer periphery of the head to the shaft. The first channel portion is connected to the second channel portion. The pin is inserted through the second hole and into the first hole to place the head in contact with the second base of the printhead cap. The second base of the printhead cap seals along the first channel portion to define a first vent path portion.

An imaging apparatus includes a frame, and a maintenance station coupled to the frame. The maintenance station includes a maintenance housing having an end portion. A maintenance sled is movably mounted to the maintenance housing. The maintenance sled has a first position and a second position. A flexible member is mounted to the maintenance sled. The flexible member includes a main body and an elastic portion extending from the main body. The main body and the elastic portion define a cavity. The elastic portion of the flexible member contacts the end portion of the maintenance housing when the maintenance sled is in the first position.
摘要:
A method of performing periodic maintenance on a printhead in an ink jet printer, includes the steps of: applying electrical power to the ink jet printer at a start time; determining an elapsed time since the start time; comparing the elapsed time with a determinate time period; and performing a printhead maintenance routine, after the elapsed time reaches the determinate time period, and independent of usage of the printhead.

An imaging apparatus includes a maintenance station mounting a printhead wiper having a waste ink collection surface. A printhead carrier carries a printhead and a printhead wiper cleaning mechanism for cleaning the printhead wiper. The printhead wiper cleaning mechanism includes a hook member for contacting the waste ink collection surface of the printhead wiper for removing residual waste ink from the waste ink accumulation surface as the printhead wiper cleaning mechanism moves relative to the printhead wiper.
