Appendix 1: Method for Replacing Paper in the Panel Printer
The printer equipped with the instrument has been installed with a paper roll at the factory. When the paper roll inside the printer is used up, a new paper roll needs to be installed. The specific installation process is as follows:
(1) Remove the front cover of the printer.
(2) Remove the entire printer from the instrument panel. Use your fingers to pinch the movable tabs on both sides of the printer inward, and gently take the entire printer off the instrument panel. Note: Before removing the printer, make sure the printer power is turned off.
(3) Remove the paper roll shaft from the printer.
(4) Slide the new paper roll onto the paper roll shaft, and install the shaft into the guide slot of the printer so that it does not fall out.
(5) Cut the paper head into a cone shape.
(6) Turn on the printer power, press the SEL key to turn off the SEL indicator light, then press the LF key to rotate the print head. At this time, use your hand to feed the paper head into the paper inlet below the print head. The paper will quickly enter the print head until it emerges from the front of the print head. The exposed part should have a certain length. Press the SEL or LF key again to stop paper feeding. Turn off the power, close the front cover of the printer, and thread the paper head out through the outlet on the front cover.
(7) Install the entire printer back onto the instrument panel.
