摘要:
An inkjet printer (100) comprising: a media supply (412); and a gripless driven roller (452) and an idler roller (450) arranged, in use, to take up the media therebetween from the media supply (412) and feed it past a printhead (200) having a plurality of ink ejection nozzles arranged to print on the media as it is fed past the nozzles, the driven roller (452) being rotatably driven so as to impart translational motion to the media upon contact with the media, wherein a contact surface of the gripless driven roller (452) which contacts the media is substantially plain.
摘要:
A system for interconnecting a printhead cartridge and a cradle unit for supporting the cartridge. The system includes an interface (564) at which the cartridge is removably engageable with the cradle unit, the interface has a power regulation circuit incorporated within the cradle unit for regulating the supply of power from the power supply to the print head cartridge.
摘要:
A printhead assembly (204) comprising: at least one printhead integrated circuit (218) having a plurality of ink ejection nozzles (214); and an ink distribution support (210) mounting the, or each, printhead integrated circuit, the ink distribution support being arranged, in use, to distribute ink to the nozzles, the printhead assembly being arranged to be mounted to the printer (100) at the ink distribution support, wherein the ink distribution support is provided with at least one reference feature (282, 284), the, or each, reference feature serving to provide information on the location of the nozzles upon mounting of the printhead assembly to the printer.
摘要:
An inkjet printhead comprising an array of ink chambers, each having a nozzle (25), an elongate actuator for ejecting ink through the nozzle (25), wherein the nozzle (25) has an elongate shape with its long dimension aligned with that of the elongate actuator.
摘要:
Feed mechanism for wide format printer (1), feed mechanism comprising: supply spool (4): take-up spool (5); take-up motor (14) operatively connected to take-up spool; take-up control system for controlling torque of take-up motor (27); drive roller system (107) positioned between supply spool and take-up spool; drive motor operatively connected to drive roller system wherein, in use, a web (24) fed from the drive roller system to the take-up spool is maintained under substantially constant tension by regulating the torque of the take-up motor using the take-up control system.
摘要:
A process for modifying the surface profile of an ink supply channel (6) in a printhead is provided. The process comprises the steps of providing a printhead comprising ink supply channels, and ion milling the ink supply channel (6). The ion milling is generally performed with argon and tends to taper and/or round angular sidewall features (12) in the channel.
摘要:
An inkjet printer unit (2) is provided comprising a media input assembly for supporting media for printing, a media output assembly for collecting printed media, and a print engine for printing an image on the media. The unit being configured such that the media output assembly is an image reading unit and the printed media is collected on a surface of the image reading unit (701).
摘要:
A digital photofinishing system comprising a digital processor, a printer and means for feeding print media to the printer from a roll of the print media; the digital processor being arranged to receive digitised data that is representative of a photographic image and to process the data in a manner to generate a printer drive signal that is representative of the photographic image, and the printer being coupled to the digital processor and being arranged to process the drive signal and effect page-width printing of the photographic image on the print media as it is fed to and through the printer from the roll.
