Troubleshooting 'Invalid Ticket' errors on Power.Gate ticket validators. Diagnose barcode scanner, power fluctuations, and environmental factors in commercial kiosks.
Typically 20-30V DC, but refer to the model's specification sheet.
This information is usually in the technical manual; common types are Code 128, Code 39, and QR codes.
Potentially, depending on the installation; check network cable presence and documentation.
Ticket validation involves barcode scanning, data decoding, and verification against internal date/time logic and potentially a lookup table. The barcode scanner likely operates on a 5V DC or 3.3V DC rail. Data is transmitted via a serial protocol (e.g., RS-232, USB) to the main validator control board. The error likely stems from power fluctuation (brownout) on the 24V DC solenoid or barcode subsystem, or signal attenuation across the data lines. ESD events can corrupt the barcode scan data.
The Power.Gate ticket validator displays an 'Invalid Ticket' error when presented with a ticket assumed to be valid based on its printed date.
The Power.Gate ticket validator operates on 24V DC. While this voltage is generally considered low-voltage, improper handling or damaged wiring can still pose a shock hazard. Ensure the power supply is disconnected before performing any physical inspections or cable adjustments. Be aware of sharp edges on the kiosk enclosure.
Regularly clean the barcode scanner lens and surrounding area. Ensure proper ventilation to prevent overheating. Inspect and secure all cable connections to prevent loosening. Periodically review and update the validator's firmware as recommended by Power.Gate. Install surge protection on the power line to mitigate voltage spikes.
Barcode scanners can be sensitive to ambient light. Shielding the scanner from direct sunlight or bright artificial light may improve its performance, especially in outdoor or brightly lit environments. A low-quality power supply can introduce noise on the DC bus. Replacing the power supply with a higher quality unit can often resolve intermittent barcode scanner failures.
