Printhead Control Boards

Printhead control boards are the signal and drive layer between your printer mainboard and the printhead. In industrial inkjet and UV systems, the board is responsible for stable firing control, signal transfer, voltage management, and communication with the carriage or head assembly. When the board is damaged, misconfigured, or incompatible, printers may show no firing, unstable output, missing channels, or communication errors.

This collection includes printhead boards for common industrial inkjet platforms such as Epson I3200, XP600, Ricoh, and other wide-format or UV printer configurations. When choosing a board, always verify the printhead family, cable layout, voltage requirements, and machine model before ordering.

How to Choose the Right Printhead Control Board

• Match the board to your exact printhead family, such as I3200, XP600, Ricoh, or Kyocera-compatible systems.
• Check whether you need a main board, carriage board, adapter board, or signal board.
• Confirm cable position, firmware expectations, and connector layout before replacement.
• Review whether the fault is actually in the board, the cables, or the printhead itself.

Common Replacement Scenarios

• No ink firing even though the head and ink system are normal.
• Unstable channels, intermittent output, or missing nozzle groups.
• Communication faults between carriage and mainboard.
• Damage caused by short circuits, ink contamination, or incorrect voltage.

FAQ

What is a printhead board in an inkjet printer?

A printhead board is the electronic control board that manages signal transfer and firing behavior between the printer control system and the printhead.

How do I know which printhead board I need?

Check the exact printer model, installed printhead model, connector layout, and existing board number before ordering.

Can a bad printhead board cause missing colors or no firing?

Yes. A failing control board can interrupt signal output, create unstable firing, or prevent certain channels from working correctly.
