2. The top view shows the circuit board asindicated on figure 3.3.1. The Variable Resistor (VR) can be
adjusted the wayseither counter-clockwise forlowertransmit power (lesssensitivity) or clockwise for
highertransmit power(higher sensitivity). Each slight adjustment ofthe VR hasto be verified bypressing
the feed button at least 7 times.

4-2. EZ- 2PS/4PS Option withStripper
EZ-2PS / EZ-4PS are modelEZ-2P/4P with stripper
installed. Figure 1.2.1 shows the inside components of
EZ-2PS. The self-strip rollerisjust belowthe platen
roller. The printer separatesthe label fromthe label
liner.
Note:
Although the stripperfunction can even support a
label as short as 15mm, we suggest that the
minimumlabel height be more than 20mm.
Fig. 4.2.1
Howto use stripper
The label sensor is hidden inside the top cover. Thissensor keepsthe printer fromprinting the next label until
you remove the previouslystripped label. The liner paper is going out fromthe lineroutput bar. Please follow
these steps.
