Every time you open Creality Scan and connect the scanner device, after initialization is complete, it will obtain and verify relevant parameters from the scanner's camera. Only when these parameters are correct can good scanning results be obtained.
Generally, if the scanner's USB connection is unstable, the firmware does not start normally, or the parameters themselves are abnormal causing verification failure, you may receive this failure prompt.
If this exception occurs, users can try the following:
(1) Confirm that the USB cable connection is stable (the screws on the scanner's USB port are tightened)
(2) Long press the button in the upper left corner of the scanner to restart the firmware. At this time, the scanner will disconnect and reconnect. After successfully reconnecting, obtain the parameters again
(3) Run the factory reset operation in the settings.
Note: Factory reset cannot be performed when connected via WiFi. Factory reset is only allowed via USB.
During factory reset, the software will obtain the best backup parameters based on the scanner's SN code. The software may need to obtain parameters from the Creality service so please ensure a stable network connection during factory reset.
If the software cannot find matching data on the server for the obtained SN, it will prompt an SN code error. In this case, please contact Creality customer service via email at cs@creality.com. Please include the scanner's SN, scanner log, and operations performed before the anomaly occurred, such as calibration, firmware upgrade, etc., in your email.
Creality Scan software uses CRC verification to confirm whether the parameters are correct.
CRC verification is a cyclic redundancy check algorithm, which is very common in the computer field. The CRC algorithm can quickly generate a short fixed-digit check code based on the parameters read from the scanner to detect or verify possible errors in the parameters.
If you see this error after performing a factory reset on your Raptor or RaptorX scanner, please contact Creality customer service via email at cs@creality.com. Please include the scanner's SN code, scanner log, and operations performed before the anomaly occurred, such as calibration, firmware upgrade, etc., in your email.
