Apropriado NC-CylinderElf-IV-A Nozzle plate replacement​ becomes necessary only when serious physical impact damages the nozzle plate, ocorre vazamento de tinta interna, surge falha elétrica permanente, ou uma grande perda fixa do bico persiste apesar dos procedimentos de recuperação aprovados. The nozzle plate is the most sophisticated, core, and expensive component of your UV printer. Before approving replacement, diagnose the complete ink system—a new nozzle plate will not solve a damaged cap, blocked filter, air leak, failed pump, or unstable pressure. NOCAI’s daily maintenance standard requires printing a nozzle test before production; minor clogging resolves through automatic cleaning or manual inking, not plate replacement.

Preparação

Desligue a impressora e desconecte o cabo de alimentação. Wear an anti-static wrist strap and gloves. Prepare uma limpeza, static-free workspace. Você vai precisar: a new genuine NOCAI motherboard matched to the NC-CylinderElf-IV-A revision, a Phillips screwdriver set, pinça, etiquetas de cabos (or masking tape), a camera or smartphone to photograph cable routing, and the user manual. Confirm the rated voltage is AC 220V, 50/60Hz before any electrical work.

Removing the Old Motherboard

Open the electrical cabinet. Antes de desconectar qualquer coisa, photograph every cable connection and label each plug with its position. Disconnect cables one by one—starting from the outermost connectors—and label them clearly. Remove the grounding screw first, then the mounting screws securing the board to the chassis. Gently lift the old board out, holding it by the edges only. Never touch the gold contacts or components with bare hands.

Installing the New Motherboard

Position the new board with the exact same orientation as the old one. Hand-tighten the mounting screws first, então proteja-os totalmente. Seguindo suas fotografias e etiquetas de cabos, reconnect each plug to its matching port. Ensure the ground wire is connected first and locked. Route cables neatly to avoid stress on connectors. Double-check that no plug is reversed and no spare connector is left unaccounted for.

Teste e calibração

Reconecte a alimentação e ligue a impressora. The control panel should boot normally. Once booted, run the calibration wizard from the RIIN software to reset printhead, motor, and sensor parameters. Print a comprehensive test pattern to verify all functions—printheads, X-axis motor, capping station, and the negative-pressure ink system. If the printer fails to initialize, power off immediately and re-verify cable mapping. Se as anomalias persistirem, contact your local NOCAI distributor for technical support. Once all systems operate correctly, the NC-CylinderElf-IV-A Motherboard replacement​ is complete and the printer is ready for production.

Cuidados pós-substituição

Maintain a stable power environment to protect the new board. Schedule periodic electrical cabinet inspections to prevent dust accumulation. Keep the workshop at 25–28°C and 35–65% RH. Observe que a garantia de manutenção de um ano exclui peças relacionadas à tinta; using non-NOCAI ink may void after-sales support.
