INK COVER OPEN-CLOSE MECHANISM
To keep the ink cartridges from being removed during printing, opening/closing of the
ink cover is electrically regulated. Opening/closing of the cover is controlled by the
lock mechanism that takes advantage of an electromagnetic solenoid, and the cover can
only be opened by means of the operation panel. When the operation to open the cover
is performed, the solenoid is energized and the lock is released. The solenoid unit is
equipped with a switch sensor that detects opening/closing state of the cover.
