Troubleshooting

Solution
The loading position of the paper may be
too high or too low. Use the micro-
adjustment feature to reset the loading
position so that the perforation is centered
within the skip area. Refer to 3-12.
Your application program may be setting
the top and bottom margins. If this is the
case, turn off skip over perforation by
setting DIP switch 2-3 to OFF. Refer to
3-10.
The printer may be set for bidirectional
printing. This can cause a slight
misalignment of graphics characters. When
precise printing of vertical lines is
necessary, select the unidirectional print
mode by sending ESC U or ESC < to the
printer. Refer to 9-9, 9-10. Unidirectional
printing is somewhat slower.
