Print engine incorporating a print media cutter assembly
View Patent ↗A print engine includes a print roll cartridge. The print roll cartridge includes a former, in turn, defining ink reservoirs for storing respective types of ink and bears a wound length of print media upon which the stored ink can be printed. The print roll cartridge defines a print media exit slot and includes a feed arrangement arranged to feed the print media through the exit slot. A printhead assembly includes an ink feed arrangement, in turn, defining ink feed galleries which can be connected in fluid communication with respective ink reservoirs. An elongate printhead is arranged relative to the ink feed arrangement to print ink fed from the ink feed galleries onto the print media fed through the exit slot. A motor assembly is coupled to the former and the feed arrangement to feed the print media through the exit slot. A cutter assembly is arranged to cut printed print media from the remaining print media wound upon the former.
1. A print engine comprising:
a print roll cartridge having a former defining ink reservoirs for storing respective types of ink and bearing a wound length of print media upon which the stored ink can be printed, the print roll cartridge defining a print media exit slot and comprising a feed arrangement arranged to feed the print media through the exit slot;
a printhead assembly having an ink feed arrangement defining ink feed galleries which can be connected in fluid communication with respective ink reservoirs and an elongate printhead arranged relative to the ink feed arrangement to print ink fed from the ink feed galleries onto the print media fed through the exit slot;
a motor assembly which can be coupled to the former and the feed arrangement to feed the print media through the exit slot; and
a cutter assembly arranged to cut printed print media from the remaining print media wound upon the former, wherein
the motor assembly has a chassis defining ink supply channels for supplying ink from respective ink reservoirs to respective ink feed galleries.
2. A print engine as claimed in claim 1 , wherein the printhead assembly further has a capping arrangement configured to cap the printhead.
3. A print engine as claimed in claim 2 , wherein the capping arrangement includes:
a carrier defining a rib which can engage with the printhead; and
a displacement mechanism which can move the carrier so that the rib can be engaged and disengaged with the printhead.
4. A print engine as claimed in claim 1 , wherein the ink feed arrangement includes:
a casing; and
a spine which can be received within the casing to define the ink feed galleries.
