ESC RS m n
[Name] Enable, disable black mark detection
[Code] ASCII ESC RS m n
Hexadecimal 1B 1E 6D n
Decimal 27 30 109 n
[Defined Area] n = 0, 1, 2, 48, 49, 50
[Initial Value] Memory SW
[Function] Switchest to enable/disable black mark (BM) detection control
When switching the setting, operations are the same as when switching to enable/disable using the memory
switch. (However, that excludes the TOF operation that occurs when the power is turned ON.)
n Black mark detection settings
0, 48 Invalid
1, 49 Valid
2, 50 Executes validate + TOP to the BM cutting position + paper full cut (SP542)
This command executes a BM TOF + paper full cut only when the current setting is
specified from invalid to valid using this command. (*)
(*) Precautions when specifying n = 2
Normally, when specifed from a state where BM is valid to become invalid, the TOF to the BM cutting position
+ paper full cut is not executed. However, if this command (n = 2) is specified when the BM TOF has not been
executed once, the same operation is executed after replacing paper.
For reference, see the functions and commands below that are affected when this setting is switched.
Affected Functions
Function When BM is Valid (n = 1, 2, 49, 50) When BM is Invalid (n = 0, 48)
Press FEED Top of form to printing start position Feed one line
BM Error Supported Invalid
Memory switch (for BM) Supported Invalid
EOT status (for BM) Supported Invalid
ASB status (for BM) Supported Invalid
Affected Commands
Class Commands When BM is Valid (n = 1, 2, 49, 50) When BM is Invalid (n = 0, 48)
BM Command FF Top of form to printing start position Form feed
ESC d 2 TOF to cutting position + full cut Paper fed to cutting position + full cut
ESC d 3 TOF to cutting position + partial cut Paper fed to cutting position + partial cut
Page control ESC C Ignored Set page length to n lines
ESC C 0 Ignored Set page length to n inches
VT Ignored Feed paper to vertical tab position
ESC B Ignored Set vertical tab position
ESC N Ignored Set bottom margin to n lines
ESC O Ignored Cancel bottom margin
Note that at the point that this setting is switched, the current position is cleared to its default value in the
same way as turning the power ON.
Also, the auto-status BM sensor detection is also initialized to white.
This command is normally used with black mark detection set to “valid” by the memory switch, and it is
recommended to switch to “invalid” just once if necessary. Do not dynamically switch between valid and
invalid for each receipt.
