Printer electronics, power supply, and cables
The printer contains several electronics boards and electrical and electronic components in different
locations.
●
There are two main active boards (Main PCA and Bundle PCA).
●
One WiFi Module, which provides the WiFi functionality to the printer.
●
One interface board (Carriage PCA), which provides and converts the appropriate signals for the
Carriage (printhead interface and line sensor signaling) .
●
Three on/off sensor PCAs (Top Cover Sensor, Out Of Paper Sensor or OOPS, Output Tray
Sensor), which indicate the open/closed status of the different elements.
●
One active on/off sensor (the Ink Cartridge Cover sensor). Apart from indicating the open/closed
status of the ink cartridge cover, it includes the backup memory for all factory calibration values.
●
One encoder sensor and a feed index sensor (other than the encoder sensors located inside the
Rewinder, the Right Gear Module, and the Service Station).
●
One Power Button PCA. Located in the front panel, it is used to power the printer on and off.
●
One Power Supply (PSU), which converts the AC power line (110240 V AC) into the DC power
needed by the printer (32 V and 12 V).
The standard wiring used in the printer is Flat Flexible Cables (FFCs), to interconnect all boards
(including sensors and encoders) and distributed cables for power signals to the motors.
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.
