– 28 – 5. SETTING THE RIBBON CARTRIDGE 1. Turn the ribbon feed knob of ribbon cartridge in the direction of the arrow to remove slack in the ribbon. 2. Place the ribbon cartridge and press it to set in the Unit. When the ribbon cartridge is hard to set to the proper position, turn the ribbon feed knob in the direction of the arrow.
– 29 – 6. SETTING THE PAPER 6.1 Setting the Paper 1. Cut straight the leading edge of the paper. 2. Insert the paper squarely into the paper guide. 3. Turn the paper feed motor to feed the paper. 4. When the paper comes out of the paper outlet, turn the feed motor off, and stop the paper feed.
– 30 – 7. INSTALLATION 1. At the time of mounting the printer mechanism into its housing cabinet, put cushion material, such as, rubber foot, on the printer mechanism legs. If installed directly, reverberations occur producing noise. We recommend that you use the following rubber foot.
