Troubleshooting a CPI MEI Talos bill validator that accepts bills but fails to print receipts. Diagnostic steps, safety warnings, and preventative measures.
The Talos printer typically operates within a voltage range of 22V DC to 26V DC.
The paper path should be cleaned at least monthly, or more frequently in high-dust environments.
The Talos printer uses standard thermal receipt paper with a width of 80mm.
The Talos receipt printer communicates with the main bill validator board via a serial interface (RS-232 or USB, depending on the Talos configuration). Receipt printing is triggered by a signal from the bill validator's CPU after successful bill validation. The printer unit requires 24V DC for operation, derived internally or supplied externally. Mechanical components include the print head, paper feed motor, and cutter solenoid. A thermistor regulates print head temperature.
If the printer is consistently failing after a certain number of prints, check the thermistor reading. An out-of-range thermistor can cause the printer to shut down prematurely to prevent overheating. Use a multimeter to verify the thermistor's resistance value.
