2187864 – Sub board (Board Assy Sub) – Epson SureColor SC-F2100-F2180

The sub board (Board Assy, Sub, 2187864) is fitted to Epson large-format printers. It ensures the electronic control of a sub-system and passes the signals to the main board.

In the Epson parts list for the SureColor SC-F2100, it appears under the designation "BOARD ASSY.,SUB" in electrical section ELEC-011 (item 205), alongside the main board "BOARD ASSY.,MAIN". Do not confuse it with the 2187863, another "BOARD ASSY.,SUB" of the SC-F2100, which is the carriage sub board.
