3. Touchscreen FOX

3.1 Possible problems with the touchscreen

• Slow reaction of the touchscreen

• Screen is flickering

• Some product buttons have disappeared

• Display shows unreadable hieroglyphics instead of text

• Machine does not start completely: „Ready“ is not displayed

• Blue box with error message on left top corner of the screen

• Screen stays black

• White screen (screen only returns white light)

3.2 Troubleshooting on touch screen

Follow these instructions step by step to determine the error the fastest way.

Requirement: The CF card must be formatted with FAT or FAT32!

NTFS data system does not work!

Step 1

• Switch off machine

• Wait for 10 seconds

• Switch machine back on

• If this action does not solve the problem, proceed with step 2

Step 2

• Switch off machine

• Remove CF card (position CF card can be seen in section „3.3 Overview FOX-Print“)

• Check if there are any defects on the pins in the CF card slot

• Reinsert the CF card

• Switch machine back on

• If this action does not solve the problem, proceed with step 3

Step 3

Check FOX-Print index (see section „3.3 Overview FOX-Print“)

• Recommendation of CF card for FOX 70-Print version A-C: CF card type „take MS“

• From FOX 70-Print version D the CF card type does not matter anymore

• If this action does not solve the problem, proceed with step 4

SECTION 6

3. Touchscreen FOX

3.2 Troubleshooting on touch screen

Step 4

Perform a touch panel test in the service menu „System Check“ to check the reaction time

SECTION 6

Step 5

Communication control CPU <--> FOX-Print by LEDs.

LEDs must be blinking on both CPU and FOX-Print!

If the LEDs do not blink (LEDs are marked in section „3.3 Overview FOX-Print“ and „3.4 Overview CPU“), but are out of action or glow permanently, follow these steps:

• Switch off machine

• Plug out connection cable (see section „3.3 Overview FOX-Print“ and „3.4 Overview CPU“)

CAUTION: The machine must be turned off at the main switch before plugging the connection cable in or out. Else there can be discharges on the electronincs, which can cause errors like in section „3.1 Possible problems with the touchscreen“.

• Control the contacts on both: CPU and FOX-Print

• Plug connection cable back in

• Switch machine back on and check LEDs

• If there is still no connection repeat this step using a new connection cable

• If this action does not solve the problem, proceed with step 6

Step 6

• Switch off machine

• Change the FOX-Print

• Reconnect all cables and switch machine back on

• If this action does not solve the problem, proceed with step 7

Step 7

• Switch off machine

• Change the CPU

• Reconnect all cables and switch machine back on

Frequently asked questions

Possible problems with the touchscreen include: slow reaction, flickering, missing product buttons, unreadable hieroglyphics instead of text, machine not starting completely, blue box with error message, black screen, or white screen.

To troubleshoot touchscreen problems, follow these steps: Switch off the machine, wait 10 seconds, switch it back on. If this doesn't fix it, remove the CF card, check for defects in the CF card slot, reinsert the card, and switch on the machine. If the problem persists, check the CF card type. Finally, check the LEDs on both the CPU and FOX-Print. If they don't blink, unplug the connection cable, control the contacts on both devices, plug the cable back in, and switch the machine on.

If the machine shows "Empty grounds drawer" error, the grounds drawer might be full, the magnet might be missing, the magnet switch might be defective, or the cable between the magnet switch and CPU might have a short circuit.
