We are creating a fingerprint scanner for a client.
One of the things we noticed was that after opening the fingerprint scanner for some time without input, it automatically prints an error message and exits the application.
Fingerprint could not be identified due to an error: Error { domain: fp - device - error - quark, code: 257, message: "Device disabled to prevent overheating." }
Is there a way to disable this or prevent the scanner from timing out?

When trying to enroll a fingerprint using enroll_sync, the template fingerprint undergoes check_print which returns either a None or Some(false) value, instead of a Some(true). This is indicated by the logs saying "Not initialized".

let template = FpPrint::new(dev);    //&dev); //&dev because dev might be used later
template.set_finger(FpFinger::RightIndex);
template.set_username("test");  //&user);

println!("Username of the fingerprint: {}", template.username().expect("Fingerprint username could not be retrieved"));

let counter = Arc::new(Mutex::new(0));

let _new_print = dev
        .enroll_sync(template, None, Some(progress_cb), Some(counter.clone()))
        .unwrap();

I would like to know if this is normal behavior, or if I'm doing something wrong with my code.
The console logs when the program runs are listed below:

For whom will you scan the fingerprint?

Username of the fingerprint: t e
