A-20
Overflow calculating flattening or daily factors Action: Most likely cause is saturation of one or more detectors during the flattening
procedure.
Parameter size is invalid [E_INVALID_SIZE_I] Comment: The device state reported by the C-arm if the response to a fast query is not
a minimum length to encompass all necessary information.
Action: This may 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.
Parameter size is too large for driver [E_TOO_LONG_I] Comment: For the state machine, indicates that a reference was made beyond the
machine limits (e.g., a register reference that exceeded the number of registers; a jump
to a location beyond the end of the state machine; etc.). For all other devices, indicates
that the message response from the remote micro overflowed the internal buffers and
was partially lost.
Action: For the state machine, report this error to Hologic Technical Support. For
other devices, this error may indicate a problem on the communications bus. Follow
the procedure under "BAD CHECKSUM IN MESSAGE." for isolating I/O errors.

These messages indicate problems performing I/O operations (usually to the hard
drive, but possibly to diskette or optical).
Action: Ensure that there is adequate space on the hard drive (Check the "Room for ..."
message in the status window. You should always leave room for 1 or 2 scans). There
may be a disk problem; appropriate diagnostics should be run. If you are unable to find
a hardware problem, the message should be reported to Hologic Technical Support.
Include as much information as possible about what you were doing at the time.
PGLINE: ... Software Any message that begins this way should be reported to Hologic Technical Support.
Include as much information as possible about what you were doing at the time.
Remote device did not echo command [E_NAK_I] Comment: Whenever the first byte in a message response does not match the command
character.
Action: This is probably a communications error between the AT and the
microprocessor. Follow the procedure under "BAD CHECKSUM IN MESSAGE." to
diagnose I/O errors.
