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
• User NV memory
•Memory switches
•User-defined page
•Maintenance counter
•Paper layout settings
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be stored.
Use the TM Flash Logo Setup Utility to register graphics.
User NV Memory
You can store and read text data for multiple purposes, such as for storing a note including
customizing or maintenance information of the printer.
Memory Switches
You can make a variety of printer settings, such as print density and printing speed.
For more information about memory switches, see
"Setting the Memory Switches" on page 96.
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.
As a guide, NV memory rewriting should be 10 times or less a day when you program
applications.
