    4-3-2. Model DP8340SC 1. Make a straight cut along the top of the paper, about 1/4 inch away from the sprocket holes, (as shown in the figure). If there is perforation, cut the paper on the perforation. 2. Insert the paper squarely into the paper insertion slot until the ALARM lamp goes out. Then, hold down the FEED switch to advance the paper 8 lines, and release the switch when 8-line feeding is completed. If the paper is not fed straight during 8-line feeding, straighten the paper by pulling it back slowly as you hold the paper release lever down. If a sprocket hole is torn or enlarged, recut the paper and reinsert it as before. 3. After confirming that the paper has been fed in straight, feed the paper continuously by holding the feed switch down.

    10. WhEN pOWEr Is sUppLIEd by ThE UsEr Note : The optional AC adapter (PS8340A) has been designed specifically for this unit(DP8340). Other AC adapters may not meet the EMC technical standards. When printer power is supplied by the user rather than through the accessory power source unit, please be careful of the following points. Note 1: An electrolytic capacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply. Use a power supply of DC 12 V ± 5% and more than 2.0 A with SELV output and LPS or Class 2 (double-insulation structure) output approved by IEC60950.
