Since you have your own X431 diagun ,then you should learn how to Replacing Paper for your most ideal X431. You may hear some tips,we’d like to supply more information.The MiniPrinter uses heat sensitive, 30 X 57mm (7mm core) thermal paper.

Practically, to mount the printer paper,you just should follow 5 steps following below:

• Open the paper lid on the back of the printer
• Remove the spindle and mount the paper scroll onto the spindle.
• Place the paper spindle into the printer with the ‘shiny’ side of the paper facing up. The paper may not be fed correctly if the orientation in incorrect.
• Open the side plate, pull up the pressing road and lead the paper into the slot. Turn the feed knob clockwise until the paper comes out of the outlet.
•  Push down the pressing rod, mount the side plate, attach the paper lid and re-attach the MiniPrinter to the X-431 Main unit.

However, you can also change printer paper (standard cheap thermal printer paper) and touch-screen protective foil. Main cable is quite strong, it’s been slammed by the door or the hood several times and there are no signs of it. We have a customer who had once replaced the touch screen. He was checking the car and there was sudden black. So he called up us and we replaced it for free. Now he is using it for last 16 months without any hardware problem.
