d3
Function 6
Erases all areas of user NV
memory in a lump.
• pL, PH specifies the number of bytes of “m” and the following to (pL+pH×256).
• c1, c2 specifies key code (ID code of record).
• Total capacity of user NV memory can be specified as any of [1K, 64K, 128K, 192K]
bytes by GS ( E. Default value is 1K byte.
[Caution]
• Frequent use of this command may result in damage of NV memory. Use the Write
command to NV memory in consideration of [10 times max./day].
• Following the processing of this command, printer Busy may occur during writing data
in NV memory. While the printer is Busy, it stops receiving process. Therefore, data
transmission (including real-time command) from host is prohibited.
