Outline; Details; Method Of Confirming License Option; Inactivity Of The Transmitted License - Canon imageRUNNER 1750 Series Service Manual

■ Outline

1. Validate an optional function which has been installed but has not been validated based on
the license key issued by a license issue server (hereinafter called "LMS").
2. Invalidate the function for which a license has been already set up.

■ Details

1. Validate a license by entering the license issued by LMS via the local UI.
2. The license key issued by LMS cannot be entered via the remote UI.
3. Invalidate a license (Set the function to OFF) via the service mode.
4. Validate a license via the service mode.
5. A license with restriction (with an expiration date, restriction in the number of licenses) is
not supported. (Restriction information is not read.)
6. Some optional functions installed are in dependent relationship with each other. For
example, when using [Function A], [Function B] should be available. In this case, [Function
B] is called a slave option of [Function A]. Installation of the slave option fails when it is
found that the master option is not validated as a result of verification of the dependent
relationship.
7. Decoding and verifying a license key
Decode an entered license key and examine the validity of the license information obtained.
When an error occurs during verification, the error information is sent back to the local UI,
which displays an error message based on the information.Verification errors are assumed
to occur in the following cases.
- When a license is installed in a non-licensed device
- When an optional function included in the license does not exist in the target device
- When an optional function included in the license is a slave option and a master option is
not validated
- When an incorrect license key is entered
- When a license key is illegally altered

■ Inactivity of the transmitted license

● Inactivity of the transmitted license
Situation of using this service mode
This service mode is used to invalidate a license under the assumption that, when a device is
exceptionally replaced with another one due to a trouble (caused by the device), the license
is transferred to another device. This operation is called "invalidating transfer of a license".
Since it is possible to select the same device as a destination of the transfer, this service
mode can be also used to invalidate a function on a temporary basis. Careful attention,
however, is required because, if you invalidate a function by mistake, you need to contact a
sales company for recovery.
