1070076537 - PBA,SIGNAL LAMP

1070076537 – Signal lamp board (PBA Signal Lamp) – Canon Colorado

The signal lamp board (PBA, SIGNAL LAMP, 1070076537) is fitted to Canon Colorado printers. It drives the status signal light of the machine.

The board is identified by its "PBA.1070076537-03" label (revision A) on a bare PCB silk-screened "PB.1070076536-03". It is a small board carrying four surface-mount LEDs (V1 to V4), driven by a transistor stage (V6, V7) and connected to the machine through a 3-pin connector (X1): the signal light of the Colorado.

Compatibility & use

• Canon Colorado
• Check the cable and the 3-pin connector before replacing the board

Function

• Carries the four LEDs of the signal light and their driver stage
• Receives the power supply and the switch-on signal through the 3-pin connector X1
• Provides the electronic control of a sub-system
• Passes the signals to the main board
• Acts as an interface between the firmware and the hardware

Signs of wear

• Signal light off or LEDs only partially lit
• Signal light no longer following the machine status (signal received on X1 but no light)
• Sub-system not driven
• Electronic errors
• Loss of internal communication
• Erratic behaviour or machine stops

Replacing this part restores the machine to proper working order.
