C206 PSB/PSE Board

The C206 PSB/PSE board is a switching regulator type power supply unit and constantly supplies stable
logic and power voltages to the printer mechanism and the main control board. Also, since this C206
PSB/PSE board has the power switch in the secondly side of the circuit, it is possible to keep supplying
electricity to the C200 MAIN control board for 30 seconds even after the power switch is turned off. Using
this time difference, even when mis-operation is done by the user such as turning off the power during
the middle of printing work, it prevents unexpected trouble with the printhead from occurring, by
transferring the printhead to the cap position before complete shut down. The C206 PSB Board is for
AC100 - 120V input voltage and the C206 PSE Board is for AC220 - 240V input voltage.
