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.

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

The setting of MSW 8-5 and 8-8 can be set by "Memory Switch setup mode".
