Chapter 1 Product Overview
NV Memory
The printer is equipped with NV memory (Nonvolatile Memory) to store 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
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. Even with a serial interface model
whose transmission speed is low, high speed graphic printing is possible.
Use the TMFlogo logo registration 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 (Customized Value)
You can configure the serial interface communication conditions and other various settings of the printer.
For more information, see
"Software Setting Mode" on page 52.
1
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 read
the counter information with the Status API of the APD, OPOS ADK, or ESC/POS commands. You can use the
counter information for periodical checks or part replacement.

Flow of Setup
This chapter consists of the following sections along with the setup flow of the product and peripherals.

23
Installing the Printer
<Vertical installation>
<Horizontal installation>
Control panel for vertical installation
You can install the printer horizontally on a flat surface (with the paper exit on top) or vertically (with the
paper exit at the front). Also, you can hang it on a wall using the optional wall hanging bracket (WH-10).
Attach the control panel label for vertical installation when vertical installation (with the paper exit at the
front) is used.
• Do not place the printer in a dusty location.
• Do not knock or strike the printer. Doing so may cause defective printing.
• Be careful not to catch cables or place foreign matter under the printer during
installation.
24
Changing the Paper Width
Install/remove the roll paper guide according to the roll paper width to be used.
The width of the installed roll paper guide differs according to the model by factory default.
❏ 65* model
Equipped with the 40 mm roll paper guide.
• When using 40 mm width roll paper, use this guide.
• When using 80 mm width roll paper, remove the installed guide.
❏ 66*/67*/68* models
Equipped with the 58 mm roll paper guide.
• When using 58 mm width roll paper, use this guide.
• When using 80 mm width roll paper, remove the installed guide.
• When using 40 mm width roll paper, remove the installed guide and install the guide for 40 mm paper supplied with the
product.
Chapter 2 Setup
• Because some parts of the print head and the autocutter blade may contact the platen and
become worn out, you cannot change a smaller paper width to a larger one once you start
using the product.
• The printable area is automatically defined by detecting the installed roll paper guide.
However, to change the paper width from 58 mm to 40 mm, using the memory switch is
required. (
