Printing apparatus including components equipped with RFID wear monitoring devices

A roller including a device for monitoring wear on a surface of the roller, comprising:

• a radio frequency identification chip attached to the roller;
• and
• a sensor including at least one circuit disposed at a predetermined distance below said surface, said senor being in communication with said radio frequency identification chip wherein said at least one circuit wears as the roller wears and breaks as the roller is worn through.

A roller including a device for monitoring wear on a surface of the roller comprising:

• a radio frequency identification chip attached to the roller, and
• a sensor including at least one circuit disposed at a predetermined distance below said surface, said sensor being in communication with said radio frequency identification chip wherein said roller is constructed of a multiplicity of non-conductive layers built one upon another and wherein said at least one circuit comprises a conductive structure formed by doping adjacent portions of said layers with a conductive material, said at least one circuit wearing as the roller wears and breaking as the roller is worn through.

A printing apparatus including a roller and a device for monitoring wear of said roller, comprising:

• a radio frequency identification chip attached to said roller, and a sensor configured to monitor wear of said roller, said sensor in communication with said radio frequency identification chip.

A printing apparatus including a flexible belt and a device for monitoring wear of said belt, comprising:

• a radio frequency identification chip attached to said belt;
• and
• a sensor configured to monitor wear of said belt, said sensor being in communication with said radio frequency identification chip and including one or more circuits, each of said circuits having a separate set of conductors for connection to said radio frequency identification chip.

A fuser apparatus including a charge receptor roller, a fuser roller and a pressure roller and a device for monitoring wear of at least one of said rollers, comprising:

• a radio frequency identification chip attached to said at least one of said rollers;
• and a sensor configured to monitor wear of said at least one of said rollers, said sensor being in communication with said radio frequency identification chip.
