NV Memory (Non-Volatile Memory)

The printer's NV memory stores data even after the printer power is turned off. NV memory
contains the following memory areas for the user:

• Memory switches

• Maintenance counter

As a guide when you program applications, NV memory should be rewritten 10 or fewer
times a day.
Memory Switches
With the memory switches, which are software switches for the printer, you can configure
various settings of the printer.
For information about the memory switches see
Maintenance Counter
With this function, printer information, such as the number of lines printed, the number of MICR
readings, the number of autocuts, and printer operation time after the printer starts working, is
automatically stored in NV memory. You can read or reset the information with the TM-L500A
Utility to use it for periodical checks or part replacement.
