Specifications

• Type: Printhead driver / interface board (KM1024i)

• Printer Families: Allwin SO and LA series (model/revision dependent)

• Supported Heads: Konica Minolta 1024i (verify “i” variant and connector layout)

• Functions: Waveform drive, head voltage distribution, temperature/ID sense pass-through, data/clock routing

• Interfaces:

  • To main board: FFC / board-to-board connectors (per revision)

  • To printhead: KM1024i head connectors and HV lines (board-specific)

• Protection: On-board fusing and ESD suppression (varies by revision); ESD-safe handling required

• PCB: High-TG FR-4, lead-free RoHS construction

• Operating Range: 10–35 °C; non-condensing, dust-managed environment

• Mounting: Pre-drilled holes aligned to SO/LA carriage brackets (pattern varies)

• Packaging: Anti-static bag with protective foam

• Compatibility Note: Board codes/firmware and connector pitch can vary—match by printer model, board label, and head type before ordering.

Highlights

• KM1024i-Tuned Drive: Clean, repeatable firing pulses for accurate dot placement and sharp text.

• Printhead Safety: Circuit design helps mitigate over-current and misfire risks when correctly installed.

• Service-Friendly Layout: Labeled headers and keyed connectors speed swap-outs and diagnostics.

• Production-Grade Build: High-temperature PCB and quality components for continuous duty cycles.

• Downtime Reducer: Drop-in replacement to recover nozzles lost to signal/drive faults.

Use & Details

• Use Cases: Replacement for intermittent/misfiring head boards, restoration after electrical fault, preventive spare for 24/7 operations.

• Installation Notes:

  • Power off and isolate mains; discharge static and work ESD-safe.

  • Photograph wiring/FFC routing; match connector orientation—do not force.

  • Verify head voltage/waveform parameters in service menu/RIP after install.

  • Perform carriage alignment, head rank/thermal settings (if applicable), and a nozzle test before production.

• Troubleshooting Clues: Random missing lines, unstable density, repeated “head drive” or communication errors, or faults that temporarily improve when reseating cables often indicate a failing head board (after ruling out head, fiber/ribbons, and main board).

• Compatibility Checklist:

  • Allwin model (SO/LA) and carriage revision

  • Board part label / code and connector pitch/count

  • Konica 1024i variant used (e.g., 6/13 kHz types, ink class)

  • Firmware/service parameters support

• Care & Handling: Store in anti-static packaging; avoid PCB flex; keep away from moisture and dust.

Important: Incorrect wiring or voltage settings can permanently damage the printhead and controller. Professional installation and calibration are strongly recommended. Electronics and spare parts are typically non-returnable once installed—confirm your exact model, board code, and head type before purchase.
