NC-UVDTF60 Wiper blade replacement

149 Visualizações
Apropriado NC-UVDTF60 Wiper blade replacement​ is required when prints show banding, streaks, or recurring nozzle clogging that cleaning cycles cannot fix. The wiper blade sits in the maintenance station and physically wipes the printhead surface during cleaning cycles, removing residual UV ink, dust, and debris. Um saturado, worn, or hardened blade stops cleaning and starts depositing dried ink back onto the nozzle plate—causing gradual print quality degradation. The NC-UVDTF60-PLUS user manual lists “Capping station maintenance” and general machine maintenance methods as scheduled procedures, and requires powering off the machine before any cleaning or repair. Replacing the wiper blade restores effective printhead cleaning. Because wiper work involves the ink system and printhead area, always follow the manual and use NOCAI original parts—using non-NOCAI ink voids after-sales service.

Preparação

Desligue a impressora e desconecte o cabo de alimentação. The NC-UVDTF60-PLUS user manual requires the machine to be powered off when you clean or fix the machine. Wear nitrile gloves and safety glasses. Prepare um espaço de trabalho limpo. Você vai precisar: a new genuine NOCAI wiper blade compatible with NC-UVDTF60-PLUS, lint-free foam swabs, UV DTF-approved cleaning solution, a small cup, pinça, and a lint-free cloth. Never use water-based DTF cleaning solution on a UV DTF printer, as it may cause chemical reactions and clog the printhead.

Accessing the Wiper Blade

Open the printer cover and move the printhead carriage to the maintenance/left position following the control panel instructions. Open the maintenance side panel to access the printhead area. Locate the wiper blade in the maintenance station. Using tweezers, gently soak the wiper blade surface with the approved cleaning solution to loosen dried ink buildup. Remove loosened ink with a swab or lint-free cloth. Avoid using a lint-free cloth directly on the wiper blade edge to prevent bending or damage.

Removing the Old Wiper Blade

While keeping the carriage in the maintenance position, carefully dislodge the old wiper blade from its holder. Handle it by the base—never touch the rubber wiping edge with bare fingers. If the blade is saturated with dried ink, physically worn, or the edge looks uneven or cracked, it confirms the need for replacement. Set the old blade aside for disposal.

Installing the New Wiper Blade

Take the new genuine NOCAI wiper blade. Insert it into the wiper holder with the same orientation as the old one. Ensure it seats fully and securely in its slot. Use tweezers if needed for precise placement. The rubber edge must be clean, flexível, and properly aligned to make full contact with the printhead surface. Route any related components back to their original positions.

Teste

Reconecte a alimentação e ligue a impressora. Run a cleaning cycle to allow the new wiper blade to sweep the printhead surface. Then run a nozzle check—all channels should fire completely and evenly. If some nozzles remain missing, run one more standard cleaning cycle and re-check. Print a test pattern to confirm banding and streaks are eliminated. Once the printhead is clean and output is stable, the NC-UVDTF60 Wiper blade replacement​ is complete and the printer is ready for production.

Cuidados pós-substituição

For high-volume production, replace the wiper blade monthly—a hardened wiper leaves ink residue on the nozzle plate and accelerates printhead wear. For light use, replace every 2–3 months. Daily, wipe the wiper blade rubber edge with a foam swab dampened with cleaning solution. Keep the maintenance station clean and dust-free. Observe que a garantia de manutenção de um ano exclui peças relacionadas à tinta, e o uso de tinta que não seja NOCAI pode anular o suporte pós-venda.
