6. DIAG. TEST OPERATION
Case 1
Conditions: Issue command [ESC]XS, feed command [ESC]T and eject command
[ESC]IB are received. Label pitch: 38.0 mm or less, with cut, feed gap sensor, cut position
fine adjustment value –10 mm or less, and issue mode set to C (cut). When the above
conditions are all met, the issue operation in cut issue mode is as follows:
1 Head lifted
5 Head lifted
Case 2
Generally the minimum label length which is available in cut mode is 38.0 mm. When using
a label with a length of less than 38 mm, the edge of the label may be caught on the print
head during back feed to the print start position after cutting the label gap, causing a
improper print start position.
In this case set the cut position fine adjustment value after calculating the value using the
following formula so that the unprinted label returns to the correct print start position.
However, use of this method will leave one or two printed label(s) between the print head
and the cutter. Feed or print the label(s) to remove them.
(a) Formula for cut position fine adjustment value
Cut position fine adjustment value
= (the number of labels left between the print head and the cutter) x (span of label)
= (32.8 mm/label length) x (span of label)
(example) Span of label : 30.0 mm, Label length : 24.0 mm
(b) Example

Fig. 6-10
When using a label with a length of less than 38 mm :
2 Forward feed to the cut position
>
6 Backfeed to the home position
>
* Omit the decimals of the value obtained by dividing 32.8 mm by the label length
for one unit.
(32.8 mm/30.0 mm) x 30.0 mm = 1 x 30.0 mm = +30.0 mm
