ABSTRACT:
A calculation unit for comparing specific paper attributes is stored in a nonvolatile memory with the detection results of cassettes. The unit checks whether the specific paper attributes coincide with the detection results, and calculates the weighted points for each matched item. A selection unit compares the calculated values, to select a paper feed cassette most suitable for the specific paper attributes. The results are arranged to numerically evaluate the paper feed cassettes, in this way preferentially selecting the suitable paper feed cassette. Operation keys for setting specific paper attributes are arranged to change specific paper attributes to be preferentially selected. Therefore, in a power-ON or a paper empty state, paper which is required by a user is preferentially selected from a plurality of paper feed means to decrease operations for selecting paper, thus improving operability.
