NOTE: It is important to bear in mind that FFCs are relatively delicate, so please ensure cable connectors are
not touched or dirtied during manipulation for assembly and disassembly operations.
NOTE: Ensure that you are properly grounded for any electronics or wiring manipulation.
The Main PCA
The Main PCA is located on the left-hand side of the printer. This board is the “brain” of the printer: where all
the processing and printer management occurs; control of the overall machine (digital and mechatronics) with
the battery for the Real-Time Clock. Single function and Multifunction versions share the same Main PCA.
Memory size is 1 GB.
The Main PCA also contains other elements with the following functions:
●
Battery: To maintain the internal clock running. The internal clock is used to remember the actual date,
used for cartridge life counting and warranty accounting.
●
WiFi module: Attached to the top of the board with some plastic locators, provides WiFi functionality to
the printer.
●
Buzzer: To provide acoustic signals to the user.
