恰当的 NC-UV0406-VI Origin sensor replacement​ restores reliable carriage homing and prevents start-margin errors on this A2 desktop UV printer. The NC-UV0406-VI uses two Epson I1600-U1 heads, prints 400×600 mm with 0–180 mm media height, supports CMYK+W, runs FlexiPRINT MiniServer, and works best at 20–28°C / 35–65% RH under 143W, AC 220/110V. The origin sensor detects the carriage reference at startup; when it fails, the printer may not home, show homing faults, or misalign jobs. Replacing it with a matched Nocai sensor returns stable registration.

准备

Power off and unplug the printer; wear antistatic gloves. Open the cover and prepare a Phillips driver, 镊子, 无绒湿巾, 异丙醇, and a new origin sensor specified for NC-UV0406-VI. Manually move the carriage away from the home side. Photograph the sensor position, cable route, and bracket orientation before removal.

拆除旧传感器

Locate the origin sensor near the carriage home position—often at the chassis end close to the parking area. 断开传感器电缆与主板或中间连接器的连接. 拆下安装螺丝, note the detection direction, and lift out the old unit. Check for ink mist, 灰尘, or physical damage that caused false homing.

安装新传感器

Fit the new OEM sensor in the same orientation. Align its slot or sensing face with the carriage flag/reflective target; keep the gap per manual—Nocai similar models commonly use about 2–3 mm from the flag. Secure screws lightly, reconnect the cable until it locks, and route the wire away from moving parts and the UV lamp area.

Homing Test and Calibration

Power on and watch the homing sequence; the carriage should move to home and stop precisely at the origin. 如果超出或失败, recheck alignment and connectors. Print an alignment pattern in FlexiPRINT; if the start margin drifts, adjust origin offset in the service menu. When homing is stable and registration is correct, the NC-UV0406-VI Origin sensor replacement​ is complete and the printer is ready for production.
