Ink Cartridge Holder Unit
This unit holds the four ink cartridge units and controls ink supply based on "no ink" signals from the printer.
The unit has an antenna for receiving data from ink cartridge tags. Data received through the antenna is the
basis for establishing a connection between the cartridge and the ink supply path on the printer. The ink path
is closed when cartridges are removed. The ink cartridge holder pivots on the back end and can be secured
by lifting the front end up about 80°.
Ink Cartridge
These cartridges hold the ink supplied to the printer.
Electronic ink tags embedded in cartridges contain information about the ink.
