| 摘要 |
This invention concerns a printhead capping mechanism (62) for preventing evaporation of ink from a printhead (63) when it is not in use. The inventio n has utility, for instance, in a colour printer, which uses a drop-on-demand inkjet printhead (63). The mechanism (62) includes a cap (64) fitted with an elastomeric seal (65) to seal against the face of the printhead (63), and a sponge (66) to catch drops ejected from the printhead (63) during the nozzle cleaning cycle. The mechanism (62) also includes an actuating structure operable to selectively move the cap (64) between an engaged position to pre ss against the printhead (63) and a disengaged position spaced away from the printhead (63). |
