APPENDIX B: REMAINING ROLL PAPER ADJUSTMENT
The total remaining paper varies depending on the inside and outside diameter of the roll core.
➀ Inside diameter of roll taken as 10.5 to 12.5 mm {0.41 to 0.49"} (See section 1.4, "Roll supply
device," for more details.)
Switching lever for vertical or horizontal position
Roll paper
Near end detector
Arrow B
Securing screw
Detection lever
NOTES: 1) The total remaining diameter of the paper roll is calculated φd + (2 × A), but it may vary
depending on the machine. (Default value of A is 6 mm.)
2) If the outside diameter of the paper roll is large and the remaining paper is small, the
detection level can be adjusted. (The two levels of the setting are selectable and differ
by approximately 4 mm {0.16"} in diameter.
•
Loosen the adjustment screw which stops the detector.
•
Raise the detection lever, set C to the gap (2 mm {0.08"}); then tighten the adjustment
screw.
3) If the end of the roll paper comes with a red end mark, the end mark may lift up all of the
roll paper. In this case, the remaining roll paper as measured by A in Note 1) cannot be
obtained.
4) The paper quality may cause the roll paper to become loose and result in incorrect
detection.
5) When placing the device horizontally, change the position of the detector to enable
correct detection, as follows:
•
Loosen the adjustment screw, which stops the detector.
•
Push in the detection lever.
•
Turn the knob forward until the detection lever is inserted into the other hole.
•
Tighten the adjustment screw.
•
When this is finished, check to see if the detection lever can function smoothly.
