• Code: SC680-01
• Description: DSP Start Error Correct startup of DSP (Digital Signal Processing) could not be confirmed after three attempts. The CHOPIN module on the MCU handles the digital signal processing (DSP) for the operation of the vertical feed motor (paper feed), horizontal motor (carriage movement), and roll paper motor (roll units).
• Causes: •X Cycle the machine off/on •X MCU defective (replace MCU).
• Remedy:

• Code: SC680-02
• Description: DSP Initialization Error Communication link between CPU and DSP could not be established because DSP did not start up correctly.
• Causes: •X Cycle the machine off/on •X MCU defective
• Remedy:

• Code: SC680-03
• Description: DSP Communication Error Communication between DSP and MCU was lost during machine operation.
• Causes: •X Cycle the machine off/on •X MCU defective
• Remedy:

• Code: SC680-04
• Description: PWM Control Error
• Causes: PWM which controls operation of the motors locked at LOW or HIGH due to damage to the FPGA IO terminal.
• Remedy: •X Replace MCU

• Code: SC685
