DC Power Supply
The scanner power supply unit (scanner PSU) supplies power to the scanner unit.
Overcurrent Control
The scanner PSU has an overcurrent control function. The SBU cuts electricity
when the current of a specific circuit exceeds its limit. When an overcurrent
condition is detected, nothing is displayed on the operation panel because the
power to the operation panel is cut.
The table below shows the controlled circuits and their recovery procedures.
Circuit
5V If the problem is solved, the machine goes to standby after
turning the main switch off and on.
24V
3.3 V If the problem is solved, the machine immediately goes to
standby; there is no need to turn the main switch off/on.
12V
15V
Anti-Condensation Heater
An anti-condensation heater is available as an optional unit. The anti-condensation
heater prevents condensation on the mirrors, which may occur when the scanner
unit is, for example, moved from a cold room to a warm room. Such condensation
can cause abnormal images.
