additive cartridge is not detected

1 comments:

Mr. Anderson

May 17, 2025

The additive cartridge may not be detected on the Dover 9750 for the following reasons:

1. The cartridge is not properly inserted.
2. The cartridge is not a compatible Markem-Imaje consumable.
3. The cartridge has expired or is defective.

If the reference numbers are greyed out and the cartridge is not recognized, check insertion and compatibility. If the issue persists, the cartridge batch may be defective.
