Comment: For the state machine, indicates that one of the self-limiting commands has
timed out or that the state machine continued executing into the next cycle.
Action: Report this error to Hologic Technical Support.
Driver is not installed [E_NOT_INSTALLED_I]
Comment: Returned in response to the ON_LINE command to indicate that the MAPI
driver is not installed in the system.
Action: Verify that the line DEVICE=C:\MENU\MAPIDEV.SYS is in the system
CONFIG.SYS file, that the correct interrupt level (IRQ) and I/O base
address are specified and that the file C:\MENU\MAPIDEV.SYS is
installed on the system.
Driver is off line [E_OFF_LINE_I]
Comment: Returned by any driver whenever a command is written to the driver and the
system is OFF_LINE.
Action: Put the driver back on line.
Driver missed a hardware interrupt [E_MISSED_INTERRUPT_I]
Comment: The filter drum or the X-ray hi/lo monitor is enabled in the C-arm driver and
the driver detected a dropped message from the C-arm microprocessor
(indicated by a mismatch in the message sequence field).
Action: Verify that no other software, TSR or operating system is running while you
do a scan (e.g., do not run a scan with while connected to a network or
attempt to run a scan under Windows). This may also be due to a
communications error between the AT and the C-arm. Follow the procedure
under "BAD CHECKSUM IN MESSAGE." to diagnose I/O errors.
Emergency stop active [E_EMERGENCY_STOP_I]
Comment: The system emergency stop is active, either because the operator has
pressed the emergency stop button, one of the emergency stop strips has
been touched, or because the C/C has calculated that the C-arm and the table
are within 1/10" of each other.
Action: If the emergency stop button on the operator panel is down (on), pull it up.
Verify that nothing is touching the emergency stop strips on the table. If the
C-arm and table are within 1/10", the problem is with the application (or
operator) that moved them so close. If they are not, see the discussion about
E_COLLISION_IMMINENT_I. If both E_COLLISION_IMMINENT_I
and E_EMERGENCY_STOP_I are active, the only way to recover is to
