Systems and methods for universal imaging components
A method of operating a cartridge chip installed in an imaging device includes: causing, by the cartridge chip, the imaging device to enter an error condition; monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and operating, based on the timing or sequence of the communication signals received from the imaging device during at least a portion of the error condition, in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device.
1. A method of operating a cartridge chip installed in an imaging device comprising:
causing, by the cartridge chip, the imaging device to enter an error condition;
monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and
operating in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device, the first mode of operation differing from the second mode of operation,
wherein causing the imaging device to enter an error condition comprises:
failing to respond to a signal transmitted by the imaging device.
2. A method of operating a cartridge chip installed in an imaging device comprising:
causing, by the cartridge chip, the imaging device to enter an error condition;
monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and
operating in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device, the first mode of operation differing from the second mode of operation,
wherein causing the imaging device to enter the error condition comprises:
responding incorrectly to a signal transmitted by the imaging device.
3. A method of operating a cartridge chip installed in an imaging device comprising:
causing, by the cartridge chip, the imaging device to enter an error condition;
monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and
operating in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device, the first mode of operation differing from the second mode of operation,
wherein monitoring the timing of communication signals comprises:
counting a number of clock signals between two events.
4. The method of claim 3 wherein the step of counting a number of clock signals is repeated a plurality of times.
5. A method of operating a cartridge chip installed in an imaging device comprising:
causing, by the cartridge chip, the imaging device to enter an error condition;
monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and
operating in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device, the first mode of operation differing from the second mode of operation,
wherein the first mode of operation is compatible with the first type of imaging device not having a list of banned serial numbers and the second mode of operation is compatible with second type of device having a list of banned serial numbers.
6. The method of claim 5 wherein the second mode of operation comprises:
transmitting, by the cartridge chip, a plurality of serial numbers to the imaging device to determine a serial that is not included in the list of banned serial numbers.
