ABSTRACT:
In a facsimile apparatus having a printing mechanism, the number of consumed printing papers is accumulated. When an ink ribbon is exchanged, a manual reset operation is requested. In one aspect, the request is made only when the accumulated value is in excess of a predetermined reference. In another aspect, two counters are used to accumulate the number of consumed printing papers separately from each other. If one counter is not reset when the reset operation is requested and a recovery of correct accumulated value is instructed manually, the accumulated value in that counter is updated by the other accumulated value in the other counter.
