[Troubleshooting when abnormal images occur]
(1) Check for the existence of the data which was acquired at the primary-level response stage.
Data must be acquired if it is insufficient in any way.
(2) Check the abnormal images acquired at the primary-level response stage on the monitor.
(3) Conduct the self-diagnosis test, and check the test results.
· Before proceeding with the self-diagnosis test, calibration must not be performed under
any circumstances. This is to prevent the calibration data to be gathered from being
updated before it is copied into the logs folder.
Even with the instructions followed when initially responding to the trouble, bear in
mind that the self-diagnosis must be performed first and that calibration is to be
undertaken after this.
(4) Check whether the abnormal images recur.
· If the problem occurs with a high frequency: Proceed with X-ray exposure, obtain five
abnormal images, and proceed to step (5).
· If the problem occurs with a low frequency: Obtain at least one abnormal image, and
proceed to step (5).
Note: In order to prevent deterioration of the X-ray tube during continuous exposure, a
waiting period must be provided.
(5) Replace the sensor cable (at imaging unit side). (Do this if it was not done at the
primary-level response stage.)
If the error recurs after the steps outlined above have been taken, the imaging unit must be
returned to Canon Inc. The tertiary-level response steps are then undertaken.
However, as a basic rule, requests for a tertiary-level response will not be accepted for an
imaging unit if the error concerned did not recur at the secondary-level response stage.
(Further consultations must be held with the representatives of Canon Inc.)
* When a tertiary-level response is requested, the following information must be provided
without fail:
· Details of how the system has been operated on-site (system configuration, optional
software, etc.)
· CXDI software version
· Shock sensor statuses
· All the images described as abnormal by the user as well as the images (2 or 3 of them)
taken immediately before and immediately after each abnormal image
· Abnormal images (1 to 5 of them) obtained by replication exposure
· Frequency with which the problem occurs
· Data acquired at the primary-level response stage
· Entry of what action was taken at the secondary-level response stage (enter these details
on the inquiry sheet and send off the sheet)
· Data (D:¥CCR) acquired at the secondary-level response stage
