How much maintenance does a CIJ printer need?

CIJ needs a small, regular maintenance routine: daily or weekly nozzle and gutter checks, periodic filtration and make-up fluid top-up to keep ink viscosity stable. It is more hands-on than TIJ, but the procedure is simple and keeps the continuous stream clean and the print consistent.

Budget a short maintenance window per shift; most issues trace back to skipped make-up fluid or a clogged gutter.

They use MEK or pigment inks and run 24/7 on beverage, cable, pipe and cosmetics lines where speed and contrast matter.

CIJ needs make-up solvent to keep the ink viscosity stable, and a simple daily/weekly maintenance routine keeps the nozzle clean.

For covert needs, UV-readable CIJ ink gives a mark that is invisible under normal light but verifies under a UV lamp.

Key points:

• SHICAI CIJ (continuous inkjet) coders run at 1000+ m/min with a character height of 0.6-20 mm and a throw distance near 1 inch.
• Because the stream is continuous, CIJ prints on uneven, curved and recessed surfaces that other technologies struggle with.
• Invisible and UV-readable marks are possible for covert batch or brand-protection coding.

CIJ stays relevant precisely because it is fast and forgiving of surface geometry – bottles, cans, cables and caps all get a crisp mark.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
