Chapter 3 Installing the Parts 3-1 Installing the Roll Paper n Installing the roll paper Be sure to use roll paper that matches the printer’s specifications. Using scissors, cut the leading edge of the roll paper perpendicular to the paper feed direction. Open the roll-paper cover and raise the release lever toward you. Make sure to pull the rele[...]

Insert the edge of the roll paper into the paper slot and feed the paper 5 cm beyond the tear-off edge. Tear-off -Edge Paper Slot Unroll the paper a little and pull lightly from the roll paper side to eliminate twist or misalignment. Retighten the roll paper to remove any slack. Both edges of the paper should be aligned parallel to the paper roll. [...]

3-2 Adjusting the Paper-end Detector n The paper-end detector The paper-end detector senses when the paper is nearing its end and turns on the PAPER lamp.

Do not mix labels with[...]

5-3 Miscellaneous Notes n Notes on printing and paper feeding (1) Because the TM-L60 is a line printer, it automatically feeds paper after printing the data. When the line spacing is set to a small value, the paper may be fed more than the set amount to print the data. For example, when the line spacing is set to 10 dots (10/180 inch), the printer [...]

(2) When the printer goes to the standby (data-waiting) state during printing, the printer stops printing and feeding paper temporarily. When the printer restarts, the paper may shift 1 to 3 dots at the start of printing. Graphics printing is especially affected by this. n Notes on the power supply l Turn the external power supply on after connecti[...]

d) If thermal paper touches anything which includes phthalic acid ester plasticizer for a long period, it can reduce the image formation ability of the paper and can cause the printed image to fade. When storing thermal paper in a card case or sample notebook, be sure to use only products made from polyethylene, polypropylene, or polyester. e) If t[...]
