PURPOSE:To improve serviceability so that copy condition are adjusted and an initial copy mode is set optionally on an operation part by storing data regarding image formation condition, providing software switches as various adjusting volume and setting switches, etc., and inputting data regarding image formation. CONSTITUTION:A main CPU 50 which controls the whole copying machine has a ROM, a RAM, etc., and a load system 52 is controlled under the command of the CPU through a D/A converter 51. A key matrix group 56 is provided on the operation part and a service SW, etc., are inputted dynamically in addition to a group of operation keys 1-24. The machine is adjustable in asterisk mode as service mode, so its changeover switch 60 is selected to a user side and provided at a place different from the operation part so as to inhibit general users from easily using it. The service SW is switched to adjust copying condition and set an initial copy mode optionally by key input, so the serviceability is improved and the hardware constitution is simplified. |
