FALL PREVENTION OF SHUTTERS
1. Model Name:
MX-FN14 (Option for MX-M623N/M623U/M753N/M753U)
2. Description:
Parts have been modified and added to MX-FN14 for fall prevention of shutters (*).
These measures are same as those implemented to another models .
Since parts modification increases load, the firmware has been modified so that the
electric current during shutter operation increases.
Make sure to upgrade the firmware when using modified parts.
(*) The shutters mentioned on this report is used for prevention of a paper going back to
the unit after outputting onto exit tray. (See the separate sheet for detail.)
