Control Panel PCB
The control panel PCB and the main PCB communicate with each other by serially transmit-
ting commands and data.
The control panel unit consists of a gate array, an LCD and LEDs (not provided on the
FAX1170/1270/1010/1020/MFC1770), which are controlled by the gate array according to
commands issued from the FAX engine on the main PCB.
The calendar clock is backed up by the backup circuit on the main PCB.
The panel FPC is a flexible keyboard PCB which integrates the key matrix having rubber
keytops.
