 [Caution]    [The specification which is common to the model]  
• Processed after buffering. 
• This command is not initialized by the initialization command. 
• This command is initialized by power OFF and paper type set by MSW is valid from the 
next power ON. 
• When BM paper/Label paper mode is changed to receipt mode 
Change the paper to receipt paper after sending this command (n=0) with BM paper/label 
paper set.  If the paper is changed to receipt paper beforehand, sensing the first position 
is not available when closing the cover, resulting in BM/label detection error.

Send this command (n=1) after changing the paper from receipt paper to label paper.  If 
this command is sent beforehand, label detection error is caused.
