Components
Top and bottom ISS PCAs
The ISS electronics are powered from a +12 V line coming from the PrintMech, and a linear regulator on the
ISS PCAs generates the +5 V used to power all the devices on the board.
The ISS PCAs are two electronic PCAs located at the rear of the Ink Supply Station. The ISS PCAs provide the
following:
●
Ink-Supply presence detection
●
Ink-Cartridge broken-bag detection
●
Ink-Supply smart-chip interface
●
Air-Pressure measurement and air-pump shutdown
●
Humidity and temperature measurements
●
System back-up EEPROM
Below is a picture showing the connections and components located at the rear of the ISS.
