Installing or Replacing the Paper Roll Note: Be sure to use paper rolls that meet the specifications. Do not use paper rolls that have the paper glued to the core because the printer cannot detect the paper end correctly. 1. Make sure that the printer is not receiving data; otherwise, data may be lost. 2. Open the paper roll cover by pressing the cover-open button. If the cover-open button will not open the cover, see page 3-4 in Troubleshooting. 3. Remove the used paper roll core if there is one. 1-10 Setting Up the Printer
