Abstract

A replaceable printing subassembly is disclosed. The replaceable printing subassembly includes a printbar. A fluid delivery system including a pump is fluidically coupled to the printbar. A frame is coupled to the fluid delivery system. The replaceable printing subassembly also includes a lift mechanism having an actuator to selectively move the printbar with respect to the frame.

First claim

The invention claimed is:

1. A printing device, comprising:
a chassis;
a media support mechanism; and
a replaceable printing subassembly removably coupled to the chassis, the replaceable printing subassembly including:
a printbar,
a fluid delivery system including a pump coupled to the printbar, and
a drive mechanism to position the printbar with respect to the media support mechanism.

2. The printing device of claim 1 including an inkjet printer.

3. The printing device of claim 2 wherein the inkjet printer is sheet fed.

4. The printing device of claim 1 wherein the chassis includes a housing having an opening and wherein subassembly is accessible from the opening.

5. The printing device of claim 1 wherein the drive mechanism moves the printbar from a print position proximate the media support mechanism when printing to a remote position distal from the media support mechanism when not printing.

6. The printing device of claim 1 comprising a controller having detachable signal pathways operably coupled to the subassembly to supply power and data to the printing subassembly.

7. The printing device of claim 6 wherein the detachable signal pathways include flat flexible circuits.

8. The printing device of claim 1 wherein the subassembly includes a fluid supply in fluid communication with the fluid delivery system.

9. A printing device, comprising:
a chassis;
a media support mechanism; and
a replaceable, printing subassembly removably coupled to the chassis, the replaceable printing subassembly including:
a printbar;
a fluid delivery system including a pump fluidically coupled to the printbar;
a frame coupled to the fluid delivery system; and
a lift mechanism including an actuator to selectively move the printbar with respect to the media support mechanism,

wherein the actuator includes a motor and drive and the left mechanism includes a lift guide formed in the frame.

10. The printing device of claim 9 wherein the printbar includes a print head in fluid communication with the pump.

11. The printing device of claim 9 including circuitry to supply power and data to actuate the lift mechanism.

12. A replaceable printing subassembly, comprising
a printbar having a print head;
an ink delivery system including a pump fluidically coupled to the print head;
a frame coupled to the ink delivery system;
a lift mechanism including an actuator to selectively move the printbar with respect to the frame; and
a service station operably coupled to the frame and having a wiper to clean the print head and cap to cover the print head when not in use, the service station including a guide formed in the frame.

13. The replaceable printing subassembly of claim 12 , wherein the printbar includes a printbar element having a width and a plurality of print heads spanning the width of the printbar element.
