Abstract:
1. A printer of the type which selectively deposits a color marking material onto a receiver to form an image on the receiver, the printer being adapted to sense and update data uniquely associated with a cleaning fluid consumable loaded into the printer, comprising: (a) a transceiver for transmitting a first electromagnetic field and for sensing a second electromagnetic field, the first electromagnetic field containing data for writing into a memory associated with the cleaning consumable; (b) a transponder coupled to said cleaning fluid consumable, said transponder adapted to receive the first electromagnetic field and generate the second electromagnetic field in response to the first electromagnetic field received thereby, the transponder adapted to receive energy from the first electromagnetic field that is generated by the transceiver and the energy comprising the only energy for powering the transponder and the transponder being adapted to read data from the memory and write updated data to the memory in accordance with an instruction code from the transceiver in the first electromagnetic field.
