6.2 LAYOUT OF PRINTER AND PAPER

The printer can be laid out as shown in Figure 6-4 according to the loading direction of the paper.

Design the paper outlet with an angle of 60 to 90

.

Design the paper inlet with an angle of 90

or more.

6.3 WHERE TO MOUNT THE PAPER HOLDER
When determining the layout of the paper holder, note the following:

Hold the paper so that the paper is straight to the paper inlet without any horizontal shifting, and
the center axis of the paper roll is parallel with the printer.

Keep the paper feed force to 0.49N (50 gf) or less.

Mount the platen block to the paper holder cover.
For the rotation support point, see CHAPTER 7 APPEARANCE AND DIMENSIONS .
6.4 SETTING THE PAPER
Follow these precautions when setting the paper.

Be sure to use the recommended paper described in this technical reference.

Place the paper roll into the holder facing the thermal surface outward. Also, do not use paper
with edges that are pasted or have turnups at the start of the roll. If they need to be used
unavoidably, replace with new paper roll as soon as possible before the entire roll is used up.

Keep the paper feed force to 0.49N (50 gf) or less.
OUT-OF-PAPER SENSOR
