• Code: 15.15:11
• Description: Drying fan short-circuit
• Causes: One or more drying fans have been short-circuited.
• Remedy: 1. Disconnect all drying fans except one from their own connectors. 2. Run the Fans diagnostic test. 3. If the error appears, the short-circuited fan is probably the connected one. Disconnect, connect another one and continue to next step. 4. If the error does not appear, connect the fans one by one until it does. The failing fan is the last one connected. Disconnect the failing fan and finish the test with all the fans in the array, just in case there is more than one with the problem. 5. Replace the failing fans. 6. Replace the drying fans cable.

• Code: 15.20:01
• Description: Minimum drying power has been automatically adjusted
• Causes: This error will appear only in the Service Plot. When the drying zone temperature increases in an uncontrolled manner and for no apparent reason, the firmware will automatically adjust the minimum drying power. When this happens, this error will be logged and visible in the Service Plot.
• Remedy: 1. Check that the room temperature is within the printer¡¦s operating specifications. If necessary, remove external sources of heat, such as strong lights, direct sunlight, or heaters. 2. This system error can occur if the ¡¥Minimum Drying Power¡¦ setting in the RIP is too high. Set the Minimum Drying Power to 0, and check whether the error repeats. 3. Check there are no obstructions on any of the cooling fans: Dryer, Curing, Top Cover Fans, Rear Fans. 4. Check that all the fans are functioning correctly. Check that the cables of the fans are undamaged and connected. Replace any fans if required: Top Cover Fans. Drying Fans. Curing Fans.

• Code: 16.01:00
• Description: Curing system warn-up timed out
• Causes: Problem description: The curing system is unable to warm up in the pre-defined amount of time (to 45°C for standby and 95°C to 115°C for printing).
• Remedy: 1. Check that the room temperature is within the printer's operating specifications; it should be higher than 15°C for printer operation. If it is too low, increase the room temperature. 2. Check that the input voltage is within the printer¡¦s operating specifications: see the Site Preparation Guide. 3. Check whether the substrate loaded on the printer is too transparent or reflective for the IR sensor to detect the surface temperature. You can check this by loading another type of substrate. 4. Check whether the Curing IR sensor is dirty and requires cleaning. Observe all safety precautions while working in the area of the heaters. 5. Check for an obstacle blocking the IR sensor¡¦s view. Ensure that the IR sensor is correctly installed on the printer, with no interference in the infrared light path, and that it is pointing to the substrate. 6. Perform the Curing IR sensor diagnostic check, to check the values being detected by the IR sensor. Replace the Curing IR sensor if required. 7. Replace the cables from the PrintMech PCA to the connection box. 8. Replace the PrintMech PCA.

• Code: 16.02:00
• Description: Curing system cool-down timed out
• Causes: The curing system is unable to cool down in the pre-defined amount of time.
• Remedy: 1. Check that the room temperature is within the printer¡¦s operating specifications. If necessary, remove external sources of heat, such as strong lights, direct sunlight, or heaters. 2. Check there are no obstructions on any of the cooling fans: Dryer, Curing, Top Cover Fans, Rear Fans. 3. Check that all the fans are functioning correctly. Check that the cables of the fans are undamaged and connected. Replace any fans if required: Top Cover Fans. Drying Fans. Curing Fans.

• Code: 16.03:00
• Description: Curing system temperature too high
• Causes: The curing system has exceeded the upper temperature limit (150°C).
• Remedy: 1. Check that the room temperature is within the printer¡¦s operating specifications. If necessary, remove external sources of heat, such as strong lights, direct sunlight, or heaters. 2. Check that the Curing IR Sensor Fan is turning and is correctly installed with the fan in the correct orientation. 3. Check that the cables are connected and undamaged. 4. Perform the Curing IR sensor diagnostic check, to check the values being detected by the IR sensor. Replace the Curing IR sensor if required. 5. Replace the cables from the PrintMech PCA to the connection box. 6. Replace the PrintMech PCA. 7. Check there are no obstructions on any of the cooling fans: Dryer, Curing, Top Cover Fans, Rear Fans. 8. Check that all the fans are functioning correctly. Check that the cables of the fans are undamaged and connected. Replace any fans if required: Top Cover Fans. Drying Fans. Curing Fans.

• Code: 16.04:00
• Description: Curing system temperature too low
• Causes: The curing system has fallen below the lower temperature limit (below 5°C).
• Remedy: 1. Check that the room temperature is within the printer's operating specifications; it should be higher than 15¢XC for printer operation. If it is too low, increase the room temperature. 2. Check whether the Curing IR sensor is dirty and requires cleaning. Observe all safety precautions while working in the area of the heaters. 3. Check for an obstacle blocking the IR sensor¡¦s view. Ensure that the IR sensor is correctly installed on the printer, with no interference in the infrared light path, and that it is pointing to the substrate. 4. Perform the Curing IR sensor diagnostic check, to check the values being detected by the IR sensor. Replace the Curing IR sensor if required. 5. Replace the cables from the PrintMech PCA to the connection box. 6. Replace the PrintMech PCA.

• Code: 16.05:00
• Description: Problem with the curing system Temperature Sensor
• Causes: Signal error detected with the curing system Temperature Sensor.
• Remedy: 1. Check that the room temperature is within the printer¡¦s operating specifications. If necessary, remove external sources of heat, such as strong lights, direct sunlight, or heaters. 2. Check that the Curing IR Sensor Fan is turning and is correctly installed with the fan in the correct orientation. 3. Check whether the Curing IR sensor is dirty and requires cleaning. Observe all safety precautions while working in the area of the heaters. 4. Check that the cables are connected and undamaged. 5.
