Troubleshooting Red Ink Light on Prestige A3+ DTF Printer: Common Causes and Fixes

Question: I have a Prestige A3+ DTF printer, and the ink light is solid red. I've replaced the print head and the ink in the tanks, but the issue persists. Could this indicate a problem with the FFC cable? The cable connected to the carriage is somewhat crumpled, although the carriage seems to be functioning correctly. Could it be the cables going to the print head?

By the way, I really appreciate your videos on how to access the cable in the carriage—they were incredibly helpful!

Now, addressing the issue with your Prestige A3+ DTF printer:

When the ink light turns solid red, it can be triggered by various issues, and pinpointing the exact cause can be challenging without hands-on diagnostics. Here are some possibilities to consider:

1. FFC Cable Issues:
   The Flexible Flat Cable (FFC) that connects the print head to the mainboard is crucial for transmitting data. If this cable is crumpled, as you've described, it could be causing intermittent or faulty connections. This might lead to the red ink light being triggered, even if the carriage appears to be moving correctly. It's essential to inspect the FFC cable closely for any signs of wear, damage, or poor connections. If it's damaged, replacing the FFC cable might resolve the issue.

2. Breakout Board Malfunction:
   The signal from the "cartridges" passes through a breakout board that can override the ink information. This board plays a critical role in the proper functioning of resetting ink cartridges. If the breakout board is faulty, it can send incorrect signals, causing the ink light to turn red. Checking the breakout board for any visible signs of damage or malfunction is advisable. Replacing the board might be necessary if it's the culprit.

3. Printhead Issues:
   Even though you've replaced the print head, there's still a chance that the new printhead could be defective or incompatible. Additionally, the printhead conversion board, which adapts the L805 printhead to work with your specific printer model, could be causing the problem. A faulty conversion board can misinterpret signals, resulting in the red ink light being triggered. Ensuring that the printhead and conversion board are correctly installed and functioning is crucial.

4. Mainboard Problems:
   If all other components seem to be working correctly, the issue might lie within the mainboard itself. The mainboard is the central hub that controls all printer functions. A malfunctioning mainboard could erroneously trigger the ink light, even if other components are in good condition. Diagnosing mainboard issues can be tricky and may require professional testing or replacement.
