Description: This command executes test and diagnosis functions. The function is
specified by m.
• p
L
, p
H
specifies (p
L
+ (p
H
×256)) for the number of bytes after p
H
(n and
m).
• n is just for command compatibility and will be ignored. The parameter
is a dummy for further extensions. That is why, printer accept all values,
but don’t use anyone of them.
• m specifies the test function.
m Function
1, 49 Enter the hexadecimal dump for the
communication interface
2, 50 Print the extended seftest form
6, 54 Print a sample print
• This command is effective only when processed at the beginning of the
line.
• When processing the hexadecimal dump (m = 1, 49) the printer stays in
this test until the printer is switched off.
• When processing the hexadecimal dump (m = 1, 49) the test button is
ignored.
• The extended selftest form is the same like started by (us t) command
with additional statistic data (see 0. ).
• When print test form and print sample the actual print will be changed.
• This command is disabled in Page Mode.
• While processing the extended selftest (m=2) and sample print (m=6), it
is recommended to wait sending next print data until the actual job is
finished.
