5.4.6 Auto-size Commands
The auto-size command attempts to automatically calculate important format values for the
label header including LSY, GAP, AGD, SPG, ^D90, and the ^D91 values. The printer
feeds a sample of labels through the GAP sensors and takes an average of the values it
receives. The auto-size command uses the appropriate sensors to detect the registration
marks set by the ^D47 command. Before issuing the auto-size command, verify that the
^D47 is set to the proper setting for the media being used.
When using media that contains a blackline for the registration mark, first execute the
^A1^D47<CR> command sequence before issuing the auto-size command or the results
may be invalid.
When using media that contains a blow-hole, set software switch #4 (^D24 command) for
blow-hole detection and then issue the desired auto-size command before issuing the auto-
size command or the results may be invalid.
