Action taken to remedy CXDI-80C trouble
This chapter describes the symptoms of the trouble which may conceivably occur in the
CXDI-80C and the suspected causes of the trouble. If trouble has developed in units other than the
detector (such as the X-ray interface box or AC/DC box), repairs can be undertaken on the market
using the service parts.
Since there are no parts which can be replaced on the market in the event that trouble has
developed in the detector, carry out the checks based on the instructions given in this chapter to
determine whether the trouble that has occurred is in the detector.
The work done at the hospital or clinic is defined as the primary response, the work done in the
office of the sales company as the secondary response, and the work done at Canon Inc. as the
tertiary response.
1. Primary response
This work is done at the hospital or clinic by the service engineer of the sales company or medical
engineer (ME).
The work of checking out the detector involves checking the wireless communication, checking
the wiring connections and collecting the data
*1
on the factors involved in the trouble that has
occurred. When it has been confirmed that the trouble is in the detector by the primary response,
the unit is exchanged for an detector owned by the sales company which is loaned out, and after
the data required has been collected
*1
, the detector with the trouble is sent to the sales company.
When trouble has occurred in the wired connection, the detector cable is replaced.

For details on the data collected, refer to “4. Collecting data when trouble has occurred.”
2. Secondary response
This work is done at the office of the sales company.
The service engineer of the sales company checks on-site that there is something wrong with the
functions or performance of the detector based on checking whether the data collected at the time
of the primary response is sufficient and based on the work which has been carried out.
As soon as it has become clear to the sales company that the trouble is in the detector, details of
the detector concerned, the collected data and work carried out up to the point where it was
determined that the trouble that occurred was in the detector are entered on the inquiry sheet, and
this sheet is sent to Canon Inc.
3. Tertiary response
This work is done by Canon Inc.
On-site checks are carried out based on the data collected and work carried out up to and
including the secondary response.
Repairs are undertaken as soon as it has been confirmed that the trouble is in the detector.
* Checkpoints when conducting the checks
In order to ensure accuracy in identifying in which unit the trouble occurred, what must be
done without fail if the trouble has been resolved by replacing the unit is to replace the new
unit with the original unit and verify that the trouble recurs.
