How to Fix Epson XP600 Error 16 After Installing New Printheads and Cables

Question:
My Epson XP600 keeps showing Error 16 even after I replaced the printheads and cables. Could this mean the carriage board needs repair, and can you look at it?

Answer:

The Error 16 on Epson XP600 and similar models is typically associated with communication problems between the mainboard and the printhead assembly. Since you've already replaced the printheads and cables, it narrows down the issue to a few likely causes:

1. Carriage Board Failure

   • The carriage board (also known as the head board) is the small circuit board mounted directly on the carriage assembly. It acts as the interface between the printhead and the mainboard.

   • If this board is damaged, even brand-new printheads and cables won't resolve the error. A faulty carriage board can trigger Error 16 because the printer cannot properly detect or control the printhead signals.

2. FFC Cable Issues

   • Even though you replaced the cables, double-check their installation. Flat Flexible Cables (FFC) are fragile and must be seated perfectly straight, with no kinks or debris on the contacts. A misalignment of even one pin can cause persistent Error 16.

   • Inspect for burn marks or damage at the contact points, which may indicate a short.

3. Mainboard Damage

   • In some cases, a defective carriage board can overload the mainboard, leading to further issues. If the printer still throws Error 16 after confirming carriage board and cable condition, the problem may have extended to the mainboard.

4. Next Steps

   • Yes, we can look at your carriage board. Often, customers send us the mainboard together with the carriage board to test both in conjunction, since they work as a pair.
