Abstract
An example air purging device includes a removable housing. The removable housing includes a first fluid interface to fluidically couple a fluid tube to the housing and a bore housing a plunger. In an example, movement of the plunger from a first orientation to a second orientation allows for the removal of the removable housing.
Claims20
An air purging device, comprising:
- a housing, the housing comprising:
- a fluid interface to fluidically couple a fluid tube to the housing;
- a bore fluidically coupled to the fluid interface;
- and
- a movable plunger housed in the bore, wherein movement of the plunger from a first orientation to a second orientation allows for:
- the plunger to be translated coaxially within the bore, removing a first portion of the plunger from the bore to create a vacuum within the bore, the fluid interface, and the fluid tube;
- access to a coupling device of a printer carriage coupled to the housing, the coupling device blocking removal of the air purging device from the printer carriage while the plunger is in the first orientation and prior to translating of the plunger within the bore;
- and
- actuation of the coupling device for removal of the air purging device from the printer carriage.
6 more elements
A printing system, comprising:
- a carriage comprising a first fluidic valve fluidically coupled, via a tube, to a fluid reservoir;
- and
- a housing removably coupled to the carriage, the housing comprising:
- a first fluid interface fluidically coupled to the first fluidic valve;
- a bore fluidically coupled to the first fluid interface;
- and
- a plunger housed within the bore, wherein movement of the plunger from a first orientation to a second orientation allows for:
- the plunger to be translated coaxially within the bore, removing a portion of the plunger from the bore to create a vacuum within the bore and the first fluid interface;
- access to a latch of the carriage coupled to the housing, the latch blocking removal of the housing from the carriage while the plunger is in the first orientation and prior to translating of the plunger within the bore;
- and
- removal of the housing from the carriage.
8 more elements
A method comprising:
- placing a plunger, of an air purging device fluidically coupled to a printer carriage, from a first orientation to a second orientation;
- translating the plunger coaxially within a bore formed within and fluidically coupled to the air purging device to create a vacuum within the bore, the air purging device, and the printer carriage;
- wherein placement of the plunger from the first orientation to the second orientation provides for:
- allowing the plunger to be translated coaxially within the bore, removing a portion of the plunger from the bore to create the vacuum within the bore, the air purging device, and the printer carriage;
- access to a latch of the printer carriage that releases the air purging device from the printer carriage;
- and
- removal of the air purging device from the printer carriage.
