SurePOS 100 Technical Reference
Page 65 of 104
Code:
"@"
1Bh 17h 40h
Outline:
Note: This command is not intended for use by an application program.
The alignment routine adjusts the timing of the print wires of the two heads relative to each other.
This causes the printer to print 7 numbered vertical lines with different timing on each line. The line highlighted
with an asterisk (*) is current setting.
The diagnostic program prompts the user to select the line that prints with the highest quality
(most straight vertical lines). When the user enters the line number, the printer is set with the
value using the following command:
"n" where n is an ASCII digit between 1 and 7
1Bh 17h (for example, 31h-37h)
The printer then prints that pattern and saves the setting in NVRAM.

Code:
"{" "00"
1Bh 7B 30h 30h
Outline:
Note: This command is not intended for use by an application program.
This command adjusts the impact force of the two heads for correct print density. This causes the printer to print
11 numbered vertical lines of a solid bar. The line highlighted with an asterisk (*) is the current setting.
The diagnostic program prompts the user to select the line that prints with the highest quality (most even
darkness left to right). When the user enters the line number, the printer is set with the value using the following
command:
"{" "n1n2"
where "n1n2" are two ASCII digits between 01 and 11
1Bh 7B
The printer then prints that pattern and saves the setting in NVRAM.
