Problem Solution
Characters are lost at
the left or right end.
If lost area is about 10mm (3mm) from left and
right edge of continuous forms(single sheet),
Area-over detection control woks properly.
In this case make sure that paper size, paper
position, and left and right margins are properly
set.
Note
Preprinted dark color area, shape of corner cut,
paper skew may cause incorrect detection.
Please don’t use medium like this.
If you must use medium like this absolutely,
you can disable Area-over detection by using
setup mode. But risk of print head broken is
increase.
Incorrect paper size selection of the Printer
Driver causes right side area is lost (exactly
Printer Driver divide the page by paper size
setting and postpone divided right page). Please
check the paper size setting.
Printing is vertically
misaligned (jagged).
Use the printer’s V-ALMNT function to check
the vertical print alignment. If necessary, adjust
the print alignment. See the section Using the
Diagnostic Functions in Chapter 5.
Smaller adjustment for paper thickness causes
vertically misalignment too.
Please refer to Printing is too light or too dark.
The top margin is
wrong.
The top margin is the sum of the top-of-form
setting, the software-specified top margin, and
the printer’s TOP-MRG setting. Proceed as
follows:
 Make sure that the top-of-form setting is
correct. The factory default is 25.4 mm (1
inch). See the section Changing Top-of
Form in Chapter 5.
 Check the software-specified top margin.
Refer to your software documentation.
 Check the printer’s TOP-MRG setting. See
the section MENU1 and MENU2 Items
and Options in Chapter 5.
