Printing arrangement having printhead and ink supply assemblies
View Patent ↗A printing arrangement has a modular printhead assembly with a plurality of elongate printhead modules fast with an elongate chassis. An ink supply assembly has a number of ink reservoirs with respective ink supply devices each having two parts, namely a first part with a plurality of collars and the second part defining a number of ink chambers. Each ink chamber is configured to contain ink of a particular color and is in fluid communication with a respective ink channel of one ink reservoir via one collar.
1. A printing arrangement comprising:
a modular printhead assembly having a plurality of elongate printhead modules fast with an elongate chassis; and
an ink supply assembly having a number of ink reservoirs with respective ink supply devices each comprising a first part comprising a plurality of collars and a second part defining a number of ink chambers, each ink chamber being configured to contain ink of a particular color and being in fluid communication with a respective ink channel of one ink reservoir via one collar.
2. A printing arrangement as claimed in claim 1 , wherein the plurality of collars are of a hydrophobic, elastomeric compound configured to sealingly and releasably engage with respective ink filling formations.
3. The printing arrangement of claim 1 , wherein each end of each printhead module is shaped to form a complementary fit with each adjacent pair of printhead modules.
4. The printing arrangement of claim 1 , wherein each printhead module includes an elongate printhead configured to eject ink, and each printhead module is oriented obliquely with respect to a longitudinal axis of the chassis.
5. The printing arrangement of claim 1 , wherein the printheads are positioned on respective, parallel lines on the chassis.
6. The printing arrangement of claim 1 , having busbars for supplying the printhead modules with electrical power.
