The top and bottom margins are represented by Area 1, as shown in
the previous illustration. The top margin is defined as the distance
between the top edge of the paper and the first row of printed
characters. The bottom margin is defined as the distance between the
last row of printed characters and the bottom edge of the paper.
• There is a possibility that printing can start within one line below the
perforation and printing could continue beyond the Assured Print
Area, however paper feed precision is only reliable with top and
bottom margins of approximately one inch. Basically, you should
consider there are only 55 lines available for reliable printing.
•
The left and right margins are represented by Area 2. For reliable
printing, use a margin of at least 0.75 in for the left and right margins.
The Paper End Detection line indicates the point where the Paper Out
sensor detects the bottom edge of the paper.
Area 3 represents the distance between the Paper End Detection position
and the bottom edge of the page.
Once the last page of the fanfold paper stack is in the printer, and the
printhead has advanced past this Paper End Detection line, printing is no
longer reliable.
When the bottom end of the last page has advanced through the printer,
past the spring plate along the front of the platen, the paper should not
reverse back through the printer, because the printer could jam and cause
paper feed problems.
