Diagnosing Card Reader Problems
Symptom | First Steps |
|---|---|
Card hover produces no response (no light, no sound, no screen activity) | Check physical USB connection between reader and printer. Reseat the cable. If no change, reboot the printer. |
Reader light activates but job does not release | Confirm the user has a pending job in PaperCut. Confirm the card is a Cornell-issued ID (not a personal RFID card or phone). Try the web portal release as a workaround. |
Reader was working, stopped after a firmware or PaperCut update | Ensure device is connected to PaperCut, and check admin portal for device communication errors. Update RFID Firmware and App via device EWC or LFA. Escalate to Toshiba if driver conflict is suspected. |
Reader is physically damaged (cracked housing, broken cable) | Tag the device out of service. Replace with new RFID reader. Update and Program new RFID reader with CU Print firmware. |
Rebooting the Printer
On the device panel, navigate to the power/settings menu.
Select or (label varies by model).
Wait for the device to fully boot and return to the home screen (approximately 2-4 minutes depending on model).
Test the card reader again.
