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: • NV graphics memory • Memory switches (customized value) • User-defined page • Maintenance counter CAUTION As a guide, NV memory rewriting should be 10 times or less a day when you program applications. NV Graphics Memory Graphics, such as shop logos to be printed on receipts, can be stored. Use the TM-T88V Utility to register graphics. You can also print and confirm the registered graphics in the NV graphics memory print mode.  For detailed information about the TM-T88V Utility, see the TM-T88V Utility User's Manual.  For information about how to use the NV graphics memory print mode, see "NV Graphics Print Mode" on page 181. User-defined Page You can store character data in the user-defined page (character code table: page 255) so that you can also print characters not resident in the printer. Maintenance Counter With this function, printer information, such as the number of line feeds, the number of autocuts, and printer operation time after the printer starts working, is automatically stored in NV memory. You can read the information with the TM-T88V Utility or in a self-test to use it for periodical checks or part replacement. 34
