F.4 The printer became inoperative after you change the interface reset
signal in the memory switch setting mode
If you make a signal setting different from that of the connected interface while changing the
interface reset signal in the memory switch setting mode, the printer may become inoperative
(e.g. the FEED switch quits working).
In such a case, disconnect the connected cable to recover from the inoperative status
temporarily. After that, set the interface reset signal again to meet your interface in the memory
switch setting mode.
