3.2 Troubleshooting on touch screen

• Slow reaction of the touchscreen

• Screen is ickering

• 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)

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

to leave, press and hold for 2s

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
