Cartridge unit incorporating printhead and ink feed system |
| abstract |
A cartridge unit for an inkjet printer comprises a printhead having an array of ink ejection nozzles; a plurality of ink storage compartment, each ink storage compartment having a variable storage volume and a displaceable wall section biased to expand the variable storage volume to generate a sustained negative pressure; an ink feed system for connecting the ink storage compartment to the printhead, the ink feed system including a plurality of channels extending parallel to a length of the printhead, each channel corresponding respectively to an ink storage compartment; and a printhead maintenance assembly, the printhead maintenance assembly having a capper spring biased against the array of ink ejection nozzles for covering the array of ink ejection nozzles. The printhead maintenance assembly includes a catch element engaged with an actuator, the catch element being movable by the actuator in a direction to counteract the biasing of the capper against the array of ink ejection nozzles. Each channel has defined along a bottom thereof a series of holes. |
