Abstract

In an electrophotographic reproduction device having a wet release hot roll fuser, the need to add silicone release oil to the fuser's oil reservoir is indicated by the count contained in a counter. This counter decrements as copies or prints are made and as a positive displacement pump pumps oil out of the reservoir to the hot roll wick. When the operator adds oil to the reservoir, the counter is incremented by an amount that is related to the amount of oil that was added. Thus, at any given time, the content of the counter is an indication of the amount of oil in the reservoir. The reproduction device is manufactured with a full oil reservoir, and the counter is set to a maximum value (i.e., the number of pump activations needed to empty the reservoir).
