Hanged with "unknown printer error" LEDs ; doing the 2 button , 1 button procedure resets something and printer goes back to normal. But for how long ? or is it a page count thing like deemed lamp life "error" on video projectors, reset there resets the hours counter. Or is it like the excess toner sensor on a photocopier by monitoring for a sense current through the rising toner heap . Is a build up of gunk on the sponge falsely saying the dump tank is full or piping is clogged and producing the error. Removed the right cheek end and exposed the sponge area and a rocking sponge carrier mechanism that I've not managed to release. How to go deeper or is it a matter of just cleaning the gunk off the sponge and suction pump or similar to empty the sump and check that the silicone tubing is not clogged (somehow). If it aint actually broke - don't poke comes to mind. It looks as though you have to separate the whole underneath plastic section from the upper metal framework to get to the tank
