About the setting value of the operation line speed in SP1-153-003
During warming-up or operating on the operation panel, the motors rotate at low line speeds. At the
time, if noise occurs, start checking from [2: Low Speed]. Middle speed is for only thick paper 1 printing,
so use middle speed if abnormal noise occurs when thick paper 1 is supplied.
