SED-8860PMJ-G is a small-character continuous inkjet printer (CIJ) with white pigment ink option. It produces sharp 1-4 line, 34x34 dot matrix codes on dark or hard-to-mark surfaces, with character height 1.5-20 mm (wide
Funcionamiento
Continuous inkjet (CIJ) printing: pigment-based ink is pressurized via a precision gear pump and jetted from the nozzle as a continuous stream. A piezoelectric crystal oscillator vibrates the stream lengthwise to break it into uniform ink droplets. Each droplet is charged by a charging electrode based on the print pattern; the microprocessor monitors via the detecting electrode. Charged droplets deflect through a high-voltage deflector plate to land at the desired pixel on the substrate; uncharged droplets return to the gutter for re-circulation. White pigment ink delivers high-contrast marks on dark surfaces. Mixer tank meters ink + diluent to maintain target viscosity (50-120). Auto-regulation of gear-pump pressure, modulation voltage and phase-detection voltage; gutter and EHT sensors trigger immediate stop on fault.

Limpieza y mantenimiento
Built-in water tank performs automatic nozzle cleaning. Three stop modes: Quick Stop (~30 s, no cleaning), Normal Stop (~3 min, with nozzle cleaning - everyday use), Special Stop (~5 min, repeated cleaning - long downtime). Modular ink core simplifies predictive maintenance. Use only manufacturer-specified cleaning fluid.
