If the machine is being used where humidity is high:
- Turn on the tray heaters of the main unit. This will prevent moisture from collecting around and in the paper trays while the machine is idle or switched off.
- If an LCIT is installed, we recommend installing the optional tray heaters in the LCIT. This will prevent moisture from collecting around and in the paper trays in the LCIT while the machine is idle or switched off.
