LSS Adjustment, cont.
When the printer is set up for "Ticket (w mark)", the light is emitted
from the lower part of the LSS. The beam can be refl ected back
to the receiver by the white back side of the media. If the beam
hits a black mark, practically no light will be refl ected back. An
out-of-paper condition is assumed, when no refl ected light has been
detected within a feed length corresponding to the distance between
the dot line on the printhead and the sensor.
Obviously, it is important that the printer is set up for the correct type
of media (see "Media Type" later in this chapter) so the fi rmware
can interpret the signals correctly.
The LSS can be moved max. 50 mm sideways across the web as
described in Chapter 13.
The LSS is automatically fi ne-adjusted when a Testfeed operation
is performed. Moreover, the LSS emitters can be adjusted in regard
of light intensity in the Setup part of Intermec Shell Enhanced
(see Chapter 13) or by means of setup fi les, and the LSS receiver
can be adjusted by means of a potentiometer on the CPU board
(see Appendix 3).
If the printer works as expected, there is no need to adjust the LSS,
but if the printer starts to feed out labels or tickets in an unexpected
manner, check that the sensor is properly aligned in relation to
the web and that it has not become dirty. Perform a few Testfeed
operations to allow the sensor to auto-adjust itself.
If the error remains, proceed according to the description of the
Setup Mode for the printer model in question. Only as a last resort
should the potentiometer be adjusted.

Feed Adjustment

The Feed Adjustment controls how much of the media is fed out or
pulled back before and/or after the actual printing. These settings are
global and will be effected regardless of which program is run.
Note that the fi rmware detects the front edges of labels w. gaps, the
ends of detection slots, and the forward edges of black marks for
detection, all seen in relation to the feed direction.
