ABSTRACT:
Wetting an absorber material in the bottom of a spittoon in a service station employed in a thermal ink-jet device, such as a facsimile machine, prevents formation of stalagmites of ink and ensures trouble-free operation of the service station. The absorber, which comprises a material having a high capacity for absorbing the liquid ink, is wetted with a sufficient quantity of a liquid having both a low vapor pressure and capable of wetting the absorber material. Such a liquid comprises a hydrocarbon material, such as a paraffin oil.
