Abstract
Official abstract text for this publication.
An integrated inkjet module includes: a print bar chassis including: an elongate frame mounting one or more printheads, the elongate frame having first and second pairs of opposed legs extending downwardly from respective first and second ends thereof, each leg having a set of roller bearings configured for bearing against a respective guide rail of the inkjet module; a support chassis configured for fixedly mounting on a media feed chassis; and a lift mechanism for lifting the print bar chassis relative to the support chassis.
First claim
Opening claim text (preview).
The invention claimed is: 1. An integrated inkjet module comprising: a print bar chassis including: an elongate frame mounting one or more printheads, and first and second pairs of opposed legs extending downwardly from respective first and second ends of the frame, each leg having a set of roller bearings configured for bearing against a respective guide rail of the inkjet module; a support chassis configured for fixedly mounting on a media feed chassis; and a lift mechanism for lifting the print bar chassis relative to the support chassis. 2. The inkjet module of claim 1 , wherein the first and second pairs of opposed legs are positioned between respective first and second pairs of datum pins. 3. The inkjet module of claim 2 , wherein each leg comprises an outwardly projecting lug, each datum pin being mounted on a respective lug. 4. The inkjet module of claim 1 , wherein each pair of opposed legs has a respective set of roller bearings bearing against opposite surfaces of respective guide rails. 5. The inkjet module of claim 1 , wherein each roller bearing is grooved for receiving part of a respective guide rail. 6. The inkjet module of claim 1 , further comprising a maintenance chassis positioned between the print bar chassis and the support chassis. 7. The inkjet module of claim 6 , wherein the maintenance chassis is slidably mounted to the support chassis. 8. The inkjet module of claim 7 , wherein the print bar chassis is fast with the maintenance chassis in a slide direction of the maintenance chassis. 9. The inkjet module of claim 8 , wherein the print bar chassis comprises a handle for effecting sliding movement of the maintenance chassis. 10. The inkjet module of claim 6 , wherein the lift mechanism comprises an hydraulic piston mechanism interconnecting the print bar chassis and the maintenance chassis. 11. The inkjet module of claim 10 , wherein a pair of hydraulic piston mechanisms are positioned at opposite ends of the inkjet module, the pair of hydraulic piston mechanisms being controlled by a common hydraulic system for synchronous movement.
