System and method for updating memories used to store information in a printing system
Electronic systems, such as printing systems, often use components that have a memory. The integral memory can be used to store information about the component. In some printing systems this memory includes storing a portion that stores a value indicative of an amount of a consumable that has been used. Discloses is a method and system for updating a memory that is integral to a component within a printing system. The value stored in the memory can be read to determine an amount of a consumable used. Alternatively, when a specific value is stored in the memory the printing system can deactivate the component.
1. A method of updating a memory module in an imaging device, comprising:
receiving, at a memory module, a command transmitted from a processing device, wherein the command indicates to the memory module to punch out a specified bit in a punch bit field;
determining a value representative of a location of the specified bit; and
storing the value in the memory module, wherein the value is stored in an array of bits within the memory module; transmitting acknowledgement that the specified bit in the punch bit field has been punched even though the specified bit has not been punched.
2. The method of claim 1 , wherein the command is indicative of usage of toner or ink in a consumable item in an imaging device.
3. The method of claim 1 further comprising:
receiving a read command signal; and
outputting the value in response to the read command signal.
4. A method of updating a memory module in an imaging device, comprising:
receiving, at a memory module, a command transmitted from a processing device, wherein the command indicates to the memory module to punch out a specified bit in a punch bit field;
determining a decimal value representative of a location of the specified bit; and
storing the decimal value in the memory module, wherein the decimal value is
stored in an array of bits; transmitting acknowledgement that the specified bit in the punch bit field has been punched even though the specified bit has not been punched.
5. The method of claim 4 , wherein the array is part of a non-volatile memory.
6. The method of claim 4 , wherein the command is indicative of usage of toner or ink in a consumable item in an imaging device.
