Explanation 

(1)  The Head Broken Dots Check Command is subject to batch processing.  If the 

Label Issue Command for 100 labels is transmitted, followed by the Head Broken 
Dots Check Command, the head broken dots check will be executed after issuing 
100 labels. 

 

 

(2)  For the all broken dots check, the head broken dots check will be made on all the 

heater elements of the thermal head. 

 

 

(3)  If the check result is found to be normal when the check result status response is set 

so that it is not made, the next command is processed.    If the check result is found 
to be abnormal, an error occurs.    Whether or not the status is sent when an error 
occurs is determined according to the setting for the status response specified by 
the Issue Command. 

 

 

 

If the check result is found to be normal when the check result status response is 
set, a head broken dots check normal end status is sent, and then the next 
command is processed.  If the check result is found to be abnormal, the head 
broken dots error status is sent, and then the printer stops. 

 

 

 

Status for normal end 

 

 

 

 

[SOH] [STX] “0020000” [EXT] [EOT] [CR] [LF] 

 

 

 

Status for head broken dots error 

 

 

 

 

[SOH] [STX] “1720000” [EXT] [EOT] [CR] [LF] 

 

 

(4)  All broken dots check takes approx. 1 second. 

 

 

(5)  Partial broken dots check: 

 

 

 

• Up to 8 positions for the range can be designated.  However, the range is 

omissible, if it is less than 8 positions. 

 

 

 

• When the value set for the start coordinate is larger than the value set for the end 

coordinate, the end coordinate is recognized and processed as the start 
coordinate, and the start coordinate is recognized and processed as the end 
coordinate. 

 

 

 

• Plural coordinates specifying the range can be designated at the same time. 

 

 

 

• If a coordinate beyond the head width is specified, it is processed the same as 

when the max. value is designated.  Therefore, a command error does not 
occur.
