ricoh mp501 humidity problem

As Phil mentioned: tray heater, problem solved.

As mentioned previously, there is NO tray heater option for the main frame or the paper bank.

At least, if it works when machine is on.
Some machines cut power to tray heater when main switch is on or when it is in enegy mode.
You find this info in your serv manual.

The reason for tray heaters is to maintain temperature inside the machine while power is off. As long as the power cord is plugged in, a circuit breaker has not been tripped or the IO board has not failed the heaters come on when the machine goes into a power down or energy saving mode, and go off when the machine wakes up.

Several parts come with little "salt bags" in the box to prevente moisture ...
You can put a few in the tray...
It's worth trying...
