Abstract

DC60 (11/05/55) The system and method for fault detection in the data received from memory (16) with replaceable printer assembly (12) includes a pari. The first bit (310C) used in conjunction with the first chunk (310D), the first chunk and parity bit one are stored in the printer memory, including the conductor wires (20). A large amount of this memory includes a large number of bits, at least one conductor cable is shared with each bit. The first piece of information and One parity is read from memory. Electrical tests of conductive wires, at least at One end of the line will be operating. Errors in one chunk are indicated depending on the first parity. Readings from memory and electrical tests Systems and methods for detecting errors in data received from memory (16) with replaceable printer components (12) include the provision of a first parity (310C). ) Used in conjunction with the first chunk (310D), the first chunk and parity bit are stored in the printer's memory, as well as a large number of electrical guides (20). Including a large number of bits, at least one conductor wire is shared with each bit. The first piece of information and One parity is read from memory. Electrical tests of conductive wires, at least at One end of the line will be operating. Errors in one chunk are indicated depending on the first parity. Readings from memory and electrical tests
