Capping device for a printer
View Patent ↗A capping device 19 for a printer movable between an open position, in which the printhead 16 may deposit ink on print media, and a closed position, in which the capping device 19 blocks the printhead 16 from depositing ink on said media, the capping device being operatively connected to at least one media feed roller 18 a whereby motion of said feed roller 18 a moves the capping device 19 between the open and closed position.
1. A capping device for a printer having a fixed/pagewidth printhead and at least one media feed roller, said capping device movable between an open position, in which the printhead may deposit ink on print media, and a closed position, in which the capping device blocks the printhead from depositing ink on said media, said capping device being operatively connected to the at least one media feed roller whereby motion of said feed roller moves the capping device between said open and closed position.
2. The capping device of claim 1 wherein said device is connected to said at least one roller via a clutch.
3. The capping device of claim 2 wherein said clutch is a friction clutch.
4. The capping device of claim 1 wherein said at least one roller is mounted for rotation about an axis of rotation and when rotated about said axis to draw said media past the printhead, the capping device is caused to move from the closed position to the open position.
5. The capping device of claim 4 wherein said at least one roller is a powered roller adjacent one or more neutral rollers.
6. The capping device of claim 1 wherein said capping device includes an arm for supporting a blotter having at least one adjacent elastomeric seal for capping a plurality of ink nozzles in said printhead.
7. The capping device of claim 1 wherein the printhead is a monolithic drop-on-demand inkjet printer.
8. A printer including:
a fixed/pagewidth printhead;
a capping device;
at least one media feed roller;
said capping device movable between an open position, in which the printhead may deposit ink on print media, and a closed position, in which the capping device blocks the printhead from depositing ink on said media, said capping device being operatively connected to the at least one media feed roller whereby motion of said feed roller moves the capping device between said open and closed position.
9. The printer of claim 8 wherein said capping device is connected to said at least one roller via a clutch.
10. The printer of claim 9 wherein said clutch is a friction clutch.
11. The printer of claim 8 wherein said at least one roller is mounted for rotation about an axis of rotation and when rotated about said axis to draw said media past the printhead, the capping device is caused to move from the closed position to the open position.
12. The printer of claim 11 wherein said at least one roller is a powered roller adjacent one or more neutral rollers.
13. The printer of claim 8 wherein said capping device includes an arm for supporting a blotter having at least one adjacent elastomeric seal for capping a plurality of ink nozzles in said printhead.
14. The printer of claim 8 wherein the printhead is a monolithic drop-on-demand inkjet printer.
