Abstract: A sheeter can include a cutting roller having a driveshaft and a removeable a cutting sleeve. The removeable cutting sleeve can simplify the process for replacing the cutting surface of a cutting roller. Additionally, the sheeter can include a mounting arrangement that supports the driveshaft of the cutting roller in a cantilevered manner, and an access portion allowing the removal sleeves to be pulled off of the driveshaft without removing the driveshaft from the sheeter.

Abstract: A method and system for protecting against unauthorized modification of a product to enhance its performance or function are disclosed. Low end products that are part of an electronic product family can be safeguarded against unauthorized enhancement of the product by hardware, software, and firmware bypasses. The operating software of the products can detect the unauthorized modification of the product or input/output device connecting to the product by reading the unique product group ID code and determining the validity of the code. Other background measures including hardware and firmware safeguards can be used to hinder or prevent the unauthorized modification. Other product specific information data can also be used to verify that the product group ID code has not been modified in an attempt to bypass the software safeguard.
