Troubleshooting OPUS7000 ticket dispenser issues: blank tickets, ribbon problems. Learn about potential causes, solutions, prevention, and safety measures.
Indicates ribbon depletion/damage likelihood.
Direct indicator of ribbon failure.
May indicate mechanical or solenoid problems.
Ticket dispensers typically use a print head and ribbon mechanism. The print head applies heat to transfer ink from the ribbon onto the thermal paper. Malfunctions can arise from ribbon misalignment, ribbon breakage, or failure of the print head's heating elements. Solenoids control the advance mechanism of the ticket stock. Voltage fluctuations or solenoid failure can cause feed problems.
The OPUS7000 ticket dispenser is dispensing blank tickets. The user reports a 'ribbon problem'.
This device operates on 24V DC. Always disconnect the power supply before performing any maintenance or inspection. High voltage may be present in the power supply itself. Lockout/Tagout (LOTO) procedures are mandatory when working on the electrical components of this device. Ensure the device is properly grounded.
Regularly inspect the ribbon and ticket stock levels. Replace ribbon preventatively. Clean the external surfaces of the dispenser to prevent dust accumulation from interfering with moving parts. Ensure proper ventilation around the unit to prevent overheating.
If the unit has an external adjustment for print head pressure, try slightly increasing the pressure. This may improve contact between the print head and the ribbon. Document original setting before any adjustment.
