Hoson Carriage Circuit Board for I3200-A1 - LJ-111124

The Hoson Carriage Circuit Board LJ-111124 is a replacement carriage-mounted PCB for Chinese DTF printers using dual Epson i3200-A1 printheads on the Hoson (Hosonsoft/BYHX) electronics platform, version HEB EPS 2H V1.43. The carriage circuit board rides on the printer's carriage alongside the printheads, receives nozzle firing data from the motherboard, and transmits printhead control signals directly to the two i3200-A1 heads via the 14-pin FFC data cables. Compatible with all Chinese dual-head i3200-A1 DTF printers running Hoson board version HEB EPS 2H V1.43, including Audley, MyColor, and Yinstar series.

Carriage circuit board — not the motherboard. The Hoson dual-head i3200 electronics system uses two separate boards: the motherboard (LJ-576565 — main control, stays static in the printer body) and this carriage circuit board (LJ-111124 — rides on the moving carriage with the printheads). These are different components. Confirm which board has failed before ordering — replacing the wrong board will not resolve the fault. See our separate LJ-576565 motherboard listing if main control failure is suspected.

LJ-111124 vs LJ-111126 — Two Carriage Board Variants

We stock two Hoson carriage circuit board variants for the dual i3200-A1 platform: LJ-111124 (this listing) and LJ-111126. Both serve the same dual-head i3200-A1 DTF printer platform and the same confirmed compatible printer list — the difference between them is a hardware or firmware revision within the HEB EPS 2H V1.43 board family. Check the part number printed on your existing carriage board to determine which variant your printer uses. If you cannot identify the part number from the existing board, contact us with your printer brand and model and we will confirm which variant to order.

What Does the Carriage Circuit Board Do?

The carriage circuit board (also called headboard or head board) is mounted directly on the printer's moving carriage alongside the i3200-A1 printheads. As the carriage travels back and forth during printing, the carriage board receives nozzle firing data from the motherboard via a flexible cable, processes the signal, and transmits the precise nozzle activation commands to each of the two i3200-A1 heads through their 14-pin FFC data cables. Each nozzle in each head fires a specific ink droplet at a specific moment based on the timing signal from the carriage board — any disruption to this signal chain produces visible output defects. A failing carriage board produces symptoms that closely mimic printhead failure: missing nozzle rows, banding, or complete colour channel loss — even when the actual i3200-A1 heads are undamaged. Diagnosing the carriage board as the failure point (rather than the head or cables) before ordering a replacement head can save thousands of dollars.

Signs Your Carriage Circuit Board May Need Replacing

• Nozzle firing failures, banding, or complete colour channel loss despite confirmed-good 14-pin cables and i3200-A1 heads

• One head in a dual-head configuration fails while the other prints correctly — with identical cable sets and heads tested good

• Printer communicates normally with RIP software and carriage moves correctly, but one or both heads produce no output

• Visible physical damage on the carriage board — burnt components, damaged connectors, cracked PCB traces

• ESD damage from an ungrounded head swap — carriage board is exposed during printhead installation and is vulnerable to static discharge

Diagnostic Checklist Before Ordering

Carriage board replacement is a significant repair cost. Before ordering, confirm:

• All 4× 14-pin FFC cables per head are correctly seated and undamaged — loose or faulty cables produce identical symptoms to carriage board failure

• The i3200-A1 printhead adapter board is undamaged — adapter board failure also produces head-not-detected symptoms

• Test each head independently if possible — if one head works and the other does not, the carriage board output for the failing head's channel may be the fault

• Visually inspect the carriage board for burnt components, damaged connector pins, or cracked traces

• Confirm the board version printed on the existing carriage board matches LJ-111124 / HEB EPS 2H V1.43 before ordering

ESD Warning — Handle with Care

The carriage circuit board contains sensitive electronic components susceptible to electrostatic discharge (ESD) damage. Always handle while wearing an anti-static wrist strap connected to a grounded surface. Do not touch contact pads, connector pins, or IC components directly. ESD damage during printhead swaps — when the carriage board is exposed and accessible — is the most common cause of carriage board failure in field service. A simple grounding precaution prevents this entirely.

Frequently Asked Questions

What is the difference between the carriage circuit board and the motherboard?
The motherboard (LJ-576565) is the main control board — it stays fixed in the printer body and manages overall printer operation: motion control, ink system, white ink circulation, USB/Ethernet interface, and RIP communication. The carriage circuit board (LJ-111124, this listing) is mounted on the moving carriage alongside the i3200-A1 heads — it receives data from the motherboard and transmits nozzle firing signals directly to the printheads via the 14-pin cables. If the printer won't power on or won't communicate with RIP software, the motherboard is likely at fault. If the printer operates normally but heads produce no output or have systematic nozzle failures despite good cables and heads, the carriage board is the likely fault.

What is the difference between LJ-111124 and LJ-111126?
Both are Hoson carriage circuit boards for the dual i3200-A1 DTF platform with the same compatible printer list. The difference is a hardware or firmware revision within the HEB EPS 2H V1.43 board family. Always check the part number printed on your existing carriage board and order the matching variant. Contact us with your printer brand and model if you cannot identify the part number — we will confirm which variant is correct for your specific printer before you order.

How do I know if the carriage board has failed rather than the printhead or cables?
Carriage board failure produces symptoms that closely mimic printhead failure. To differentiate: first confirm all 14-pin cables are correctly seated and undamaged (most common cause of head-related errors). Then confirm the adapter board between the carriage board and each head is undamaged. If cables and adapter boards are confirmed good and the head still produces no output — particularly if only one head fails while the other works on the same carriage board — the carriage board output for that head's channel is the most likely fault. Visual inspection for burnt traces or damaged connectors on the carriage board can confirm physical damage.

Do you ship Hoson carriage boards to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American DTF service technicians and production facilities using freight forwarders in the Doral area.
