Starting the Memory Switch setup mode
Use the following procedure to start the Memory Switch setup mode.
1) Open the rear cover.
2) Turn the power on while pressing the FEED button.
3) Press the FEED button twice after POWER, ERROR, and PAPER OUT LEDs are lit.
4) Close rear the cover. The printer prints the enabled settings of the memory switches and instructions.
5) Follow the instructions to process the switch setup.
These setting can be set by "Memory Switch setup mode."
All new settings will be lost if the power supply is turned off in the memory switch setup
mode. Be sure to follow the proper procedure, and turn the power off at the correct time.
There are two methods, DIP Switch and Memory Switch, to adjust the serial
communication conditions. DIP Switch1-5 selects which is effective, DIP Switch or
Memory Switch. To enable the "Serial communication" setting, you have to adjust the
"Serial interface selection" function of DIP Switch 1-5 to "Memory Switch".
These settings can be set by "Memory Switch setup mode".

CHAPTER 3
MSW 8-5 :
When Off is selected, a bit of the "paper end sensor" in each status that is transmitted
from the printer is changed every time the rear cover is open or closed. When On is
selected, a bit of the "rear cover open / close" in each status that is transmitted from the
printer is changed every time the rear cover is open or closed. When you replace a SRP-
270 with a SRP-275, you should adjust the MSW 8-5 to Off.
MSW 8-8 :
When Off is selected, a bit of the "automatic recoverable error" in each status that is
transmitted from the printer is changed every time the rear cover is open. When On is
selected, a bit of the "mechanical error" in each status that is transmitted from the printer is
changed every time the rear cover is open.
The setting of MSW 8-5 and 8-8 can be set by "Memory Switch setup mode".
