A heater chip for use in an inkjet printer which includes a single conductive layer to provide electrical connectivity between power and ground inputs. The cyclonic separator may include multiple cyclone and may be in fluid communication with the hopper assembly so as to periodically receive dust and debris exiting the filter system. A code generator generates code having orthogonality in chronological order. A wedge-shaped element is inserted into said free space from the top. In response to determining that the system boot code is compromised and non-recoverable, switch logic is activated to connect a second non-volatile memory to the shared bus and to disconnect the first non-volatile memory from the shared bus. The intermediate sleeve of either the rotary cutter on the anvil roll, or both can be formed of a material for vibration damping, thermal insulation, thermal conduction, weight increase andor weight reduction.
