Apparatus and method for lateral color registration performance and preventive maintenance detection

A computer-based apparatus for preventive maintenance detection for a color printer including a photoreceptor belt (PB) arranged to displace in a process direction, comprising:

• a memory element for a computer arranged to store at least one threshold value, computer readable instructions, and registration data for a plurality of markings, associated with a first color, on a surface of the PB, the registration data including for each marking in the plurality of markings, a respective registration difference, in a lateral direction orthogonal to the process direction, between a respective actual location and a respective original location;
• and,
• a processor for the computer configured to execute the computer readable instructions to:
• determine that at least one marking from the plurality of markings is out of compliance with the at least one threshold value;
• and,
• in response to determining that at least one marking from the plurality of markings is out of compliance with the at least one threshold value, transmit a signal, indicating that maintenance is required for the PB, for display.

A computer-based method for preventive maintenance detection for a color printer including a photoreceptor belt (PB) arranged to displace in a process direction, comprising:

• storing, in a memory element of a computer:
• a first distance;
• computer readable instructions;
• and,
• registration data for a plurality of markings, associated with a first color, on a surface of the PB, the registration data including for each marking in the plurality of markings, a respective registration difference, in a lateral direction orthogonal to the process direction, between a respective actual location and a respective original location;
• and,
• executing, using a processor for the computer, the computer readable instructions to:
• identify a first marking with a smallest respective registration difference;
• identify a second marking with a largest respective registration difference;
• determine a first difference between the smallest and largest respective registration differences;
• determine that the first difference is greater than the first distance;
• in response to determining that the first difference is greater than the first distance, identifying a registration error for the PB;
• and,
• in response to identifying a registration error, transmit a signal, indicating that maintenance is required for the PB, for display.
