Suspended inkjet printing system
A suspended inkjet printing system includes: a pair of support beams extending across a media path; a mounting frame mounted between the support beams, a print head chassis mounted on the mounting frame, the print head chassis being actuable between at least a printing position and a maintenance position; and a plurality of print heads mounted on the print head chassis, each print head extending across the media path and spaced apart along the media path in a direction of media propagation. A plurality of projections extend from the print head chassis into engagement with the mounting frame, the projections controlling a height of the print head chassis relative to the media path.
1. A suspended inkjet printing system comprising:
a pair of support beams extending across a media path;
a mounting frame mounted between the support beams,
a print head chassis mounted on the mounting frame, the print head chassis being actuable between at least a printing position and a maintenance position; and
a plurality of print heads mounted on the print head chassis, each print head extending across the media path and spaced apart along the media path in a direction of media propagation,
wherein:
a plurality of projections extend from the print head chassis into engagement with the mounting frame, the projections at least partially controlling a position of the print head chassis relative to the mounting frame; and
each projection comprises a positioning pin and the mounting frame comprises a plurality of pin bushes for receiving the positioning pins, wherein a first pin bush has a circular-conical depression and a second pin bush has an oval-conical depression.
2. The inkjet printing system of claim 1 , further comprising a maintenance chassis.
3. The inkjet printing system of claim 2 , wherein the print head chassis and the maintenance chassis are movable relative to each other.
4. The inkjet printing system of claim 2 , wherein print head chassis and the maintenance chassis are laterally relatively movable.
5. The inkjet printing system of claim 2 , wherein the maintenance chassis comprises a plurality of cappers.
6. The ink jet printing system of claim 1 , wherein the print head chassis is liftable relative to the mounting frame.
7. The ink jet printing system of claim 1 , wherein the support beams and mounting frame are at a fixed height relative to the media path.
8. The inkjet printing system of claim 1 , wherein the print heads are monochrome print heads.
9. The inkjet printing system of claim 1 , further comprising a platen arrangement positioned beneath the print heads.
10. The inkjet printing system of claim 9 , wherein the platen arrangement is configured for feeding a media web past the print heads.
