How do I replace the printer paper?
The below steps are also outlined with pictures in the X431’s User Manual, pages 7-8.
1. Open the paper lid on the back of the printer.
2. Take out the spindle and mount the paper scroll onto the spindle.
3. Put the paper spindle into the printer making sure to feed it in the proper direction.
4. Open the side plate, pull up the pressing rod and lead the paper into the slot. Turn the
feed knob clockwise until the paper comes out of the outlet at the top.
5. Push down the pressing rod, replace the side plate, attach the paper lid and recon-
nect the printer module to the main unit.
What are the functions of the two buttons on the printer module?
1. SEL key. When the LED next to this button is lit, the printer is selected and available
to print.
2. FL key: Paper-feed button
Can I print anything at any time?
You can print whatever is on the screen when the ‘Print’ button is selectable on the touch
screen. If the ‘Print’ button is grayed out or not showing, you cannot print the screen at
that time.
Why doesn’t my printer work? When I select print, it doesn’t do anything.
There are a few reasons why this may happen:
1. The SEL key next to the printer may not be selected. This button enables the printer.
When it is off, the printer will not print.
2. You may be out of paper. Check the paper and try again
3. The printer may not be connected to the main unit fully. Disconnect the printer module
and re-connect.
If these solutions don’t remedy the situation, contact your local dealer for assistance.

the machine is not operated for a specified period of time. Refer to the “Power Manage-
ment” section of the X431 User Manual to set the “power-off time” to “none” or to select a
longer standby time.
Why is the time in the lower corner of the screen incorrect? How can I fix this?
Refer to the “Clock” section in the X431 User Manual to set the correct time.
Why can’t I access the diagnostic interface upon powering up the unit?
