Chapter 1 Product Overview 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 lines printed, the number of autocuts, and printer operation time after the printer starts working, is automatically stored in NV memory. You can use the counter information for periodical checks or part replacement. You can also check the print head running length and number of times of auto-cutting with the self-test (see "Self-test Mode" on page 36 ).
The maintenance counter value is normally saved in the NV memory every 2 minutes (maximum of 4 minutes). However, it is not automatically saved when the product is in the power-saving mode or when the power is turned off without using the power switch. 18
