Chapter 1 Product Overview Maintenance Counter With this function, printer information, such as the number of lines fed, and printer operation time after the printer starts working, is automatically stored in NV memory. You can read or reset the information with TM- P80 Utility, the Status API of the APD, or OPOS ADK to use it for periodical checks or part replacement. Maintenance counter values are usually saved every two minutes except in the power saving sta- tus. However, if the printer power is turned off by removing the battery or using up the battery charge, the latest maintenance counter will not be saved.
