5. After assembling the Plate Spring, the height will be 7~10[mm] when pressing the Push
Button. If no problem Re-assemble in the reverse order.
6. After assembling the Case-Lower to Set Body, turn the Set over and attach the BRKT
Hanger to the Case Lower then tighten four screws. (Figure 3-10)
7. Attach the BRKT Mount to the wall firmly with the eight screws. Be sure that the BRKT
attached properly to match the direction of arrow as illustrated in the Figure 3-11. And the
BRKT Mount should be always fixed vertically. (Figure 3-11)

3-2-1 Setting the DIP switches
The DIP switches are located on the bottom of the printer. The DIP switches are used to set theprinter to perform various functions. Follow these steps when changing DIP switches setting:
1. Turn the printer power switch off.
2. Remove the screw on the bottom of the printer and open the bracket.
3. Flip the DIP switches using tweezers or another narrow-ended tool. Switches are on when up and
off when down in the Figure below.

5-2-1 Cleaning Head
Paper dust on the heating elements may lower the print quality. In this case, clean the print head as follows:
Caution : Turn off the printer power before cleaning.Caution : Note that the thermal head (Thermal Element and Radiation Plate) becomes very hot during
normal operation, creating the danger of burn injury. Bu sure to wait for about 10 minutes after turning printer power off before beginning the cleaning.
1. Open the cover-open.2. Clean the thermal element (the area that looks like it is marked a thin black line) of the thermal head with a cotton
swab moistened with an alcohol solvent (ethanol, methanol, or IPA).3. After confirming that the alcohol solvent has been dried up completely, close the cover-open.

[Details] * If any of the status items in the table above are enabled, the printer transmits the status when this command is executed. The printer automatically transmits the status whenever the enabled status item changes. The disabled status items may change, in this case, because each status transmission represents the current status.
* If all status items are disabled, the ASB function is also disabled. * If the ASB is enabled as a default, the printer transmits the status when the printer data reception and transmission is possible at the first time from when the printer is turned on.
* The following four status bytes are transmitted without confirming whether the host is ready to receive data. The four status bytes must be consecutive, except for the XOFF code.
* Since this command is executed after the data is processed in the receive buffer, there may be a time la between data reception and status transmission.
* When the printer is disabled by ESC= (Select peripheral device), the four status bytes are transmitted whenever the status changes.
* The status to be transmitted are as follows :
