What to do if nothing is displayed on my ISHIDA IWQ when pressing the ON/OFF key?
- B
  bruce90Aug 14, 2025
  If nothing is displayed on your ISHIDA Scales after pressing the ON/OFF key, here are a few things to check: * First, ensure that the scale is receiving AC power by confirming the voltage at the power outlet and checking the power cord for any damage (replace if necessary). * Next, test the ON/OFF key itself using a multimeter to see if it's defective and needs replacement. * Also, verify the VCC+5V supply by checking the conduction of harness C2 VCC and the SW power supply. * Finally, if none of these steps work, the main board may be defective, and you can confirm this by replacing it with a new one.

Why is the zero point or weighing value fluctuating on my ISHIDA IWQ Scales?
- A
  amy60Aug 17, 2025
  Fluctuations in the zero point or weighing value of your ISHIDA Scales can stem from several factors. It could be due to wind or vibrations at the scale's location; try moving it to a more stable environment. Check for any interference with the weighing platter, platter support, or load cell, and remove any obstructions. A defect in the A/D board or load cell could also be the cause; running Test mode C1 can help diagnose this, and you may need to replace these components. Also, verify the VEX+5V voltage between R-W of A/D board XJ2 using a multimeter; if low or fluctuating, the main board might need replacement. Electromagnetic interference can also play a role; identify and eliminate the source or relocate the scale.

What does it mean when Test Mode 'C' displays on ISHIDA Scales?
- H
  Heather BowersAug 21, 2025
  If Test Mode “C” is displayed when pressing the ON/OFF key on your ISHIDA Scales, it means the scale data is in the initialization state. To resolve this, perform a span adjustment.

How to fix a non-responsive key on ISHIDA IWQ?
- C
  Christina SmithAug 26, 2025
  If a key on your ISHIDA Scales is not responding or is hard to operate, the issue could be due to a defect in the key itself; in this case, replace the tactile key soldered to the main board. Alternatively, there might be an inappropriate gap between the key sheet and the key on the main board; adjust the main board to properly fit with the key sheet. In some cases, the main board itself may be defective and require replacement.

What to do if the printer is not reopening to a printing command from ISHIDA IWQ?
- A
  ashleywatsonAug 29, 2025
  If the printer is not responding to printing commands from your ISHIDA Scales, verify that the printer is powered on, the cable is properly connected, and the printer is online. Also, ensure that there are no errors indicated by the printer and that its transmission specifications match those of the scale. On the scale side, confirm that the cable is connected and that setup item F11 is not set to 'no output'. Check the connection via the main board XJ4 connector. If problems persist, the main board may need to be replaced.
