Systems and methods for detecting potentially defective consumables

A system, comprising:

• a plurality of machines having consumables of at least one consumable batch installed therein and sensors that take voltage based bare belt readings during print or copy jobs;
• a processor;
• and
• a non-transitory computer-readable medium comprising one or more programming instructions that when executed by the processor, cause the processor to:
• obtain the voltage or light based bare belt readings taken by the sensors during one or more print or copy processes performed by the plurality of machines;
• use the voltage or light based bare belt readings to determine whether the at least one consumable batch is a good batch or a bad batch;
• and
• perform one or more actions to control operations of the plurality of machines and/or replace the consumables in the plurality of machines in response to a determination that the at least one consumable batch is a bad batch.
