Anti-condensation Heater for Scanner, PCDU, and Paper Feed Tray
Circuit Configuration
The power circuit of the anti-condensation heaters for scanner and PCDU is linked to the switch of the
paper feed tray heater. Therefore, when the paper feed tray heater power is turned OFF, all heaters are
de-energized. In addition, the operation during printing is controlled so as not to exceed the maximum
power.
The behavior of the heaters when the machine is in standby mode is controlled by SP5-805-001 (Anti-
Condensation Heater OFF/ON).
