Ribbon Sensing Discussion
There are two basic requirements for proper ribbon sensing.
1. The printer must be configured for THERMAL TRANSFER MODE. Configuring the printer for Thermal Transfer Mode (Using Ribbon) by accessing the printer LCD Display. Locate the PRINT METHOD menu item and set it to THERMAL TRANSFER.
2. The ribbon must be loaded correctly. Ribbon Loading (Click Here for a diagram)
The RIBBON SENSE value (sensor trip point) is adjusted if you run MANUAL CALIBRATE or if the MEDIA POWER UP or HEAD CLOSE menu items are set to CALIBRATE. The RIBBON LED (Sensor Gain) is adjusted at the factory and should not require adjustment.
