Abstract
In a method or arrangement to select instructions to be executed by a control unit of a printer or copier, the control unit is connected with a plug connector arrangement providing an electrical connection to the control unit via a plurality of individual contact terminals. At least one first instruction stored in a first memory region is executed by the control unit in a first operating mode. At least one second instruction stored in a second memory region is executed by the control unit in a second operating mode. The second operating mode is set by at least one of the contact terminals of the plug connector arrangement, and wherein an evaluable signal level is respectively present at the at least one contact terminal. A memory region from which the at least one first instruction is loaded for execution by the control unit is established with aid of the electrical connection. An additional memory region from which the at least one second instruction is loaded for execution by the control unit is established in the absence of the electrical connection.

22. A method to select instructions to be executed by a control unit of a printer or copier, said control unit being connected with a plug connector arrangement providing an electrical connection to the control unit via a plurality of individual contact terminals, comprising the steps of:
-
executing at least one first instruction stored in a first memory region by the control unit in a first operating mode; executing at least one second instruction stored in a second memory region by the control unit in a second operating mode; setting the second operating mode by at least one of said contact terminals of said plug connector arrangement, and wherein an evaluable signal level is respectively present at the at least one contact terminal; establishing a memory region from which the at least one first instruction is loaded for execution by the control unit with aid of the electrical connection; and establishing an additional memory region from which the at least one second instruction is located for execution by the control unit in absence of the electrical connection. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. An arrangement to select instructions to be executed by a control unit of a printer or copier, comprising:
-
a control unit that comprises access to a first memory region and access to at least one second memory region, wherein first instructions to be executed by the control unit in a first operating mode are stored in the first memory region, and wherein second instructions to be executed by the control unit in a second operating mode are stored in the second memory region; a plug connector arrangement providing an electrical connection to the control unit via a plurality of individual contact terminals and via which the second operating mode is set with aid of at least one of said contact terminals and wherein an evaluable signal level is present at said at least one contract terminal; and the electrical connection establishing a memory region from which the control unit loads the first instructions for execution, and in absence of the electrical connection the second memory region is established, from which the control unit loads the second instructions for execution. - View Dependent Claims (34, 35)
