AcMonitor_x73.exe AcMonitor_x83.exe
(Jetsoft for Lexmark)
Lexmark X73/X83 Button Monitor. Background task installed by the drivers for the Lexmark X73 or X83 multifunction printer/scanner/copier. This background task monitors the X73/X83 for activity and interacts with ACBTNMGR_X73/83 above for operations involving the PC (e.g. scan to e-mail). Also, for large copy jobs it relays the current copy count back to ACBTNMGR_X73/X83 so you can view it on your PC.
Recommendation :
In the main this task is necessary, so leave it alone.
