In high-volume food manufacturing environments across Africa, even small improvements in coding and marking technology can deliver outsized returns. For one of the continent’s top 4 FMCG manufacturers (who prefers to remain anonymous), replacing 38 Continuous Inkjet (CIJ) printers with REA JET HR 2.0 Thermal Inkjet (TIJ) systems transformed their date coding operations on sugar packaging and delivered rapid ROI.
The Old Reality: CIJ Struggles in a Dusty Sugar Environment
Sugar production and packaging create a challenging environment. Fine sugar particles and dust are constantly present in the air around production lines. The company previously relied on 38 CIJ printers for essential date coding on its sugar packaging. While CIJ technology has been an industry staple for years, it came with significant drawbacks in this setting:
- High ongoing costs: All 38 printers were covered by expensive Service Level Agreements (SLAs), generating large monthly bills for maintenance, parts, and support.
- Frequent clogging and reliability issues: Sugar dust and residues affected the CIJ delivery systems — including pumps, motors, and filters. Ink viscosity was easily disrupted, leading to blockages and inconsistent print quality.
- Significant downtime: These issues caused frequent stoppages, hurting Overall Equipment Effectiveness (OEE) and putting production targets at risk. In a high-speed packaging environment, every minute of unplanned downtime was costly.
The combination of high SLA costs and poor reliability in the dusty environment made the existing setup unsustainable.
The Change: Full Transition to REA JET HR 2.0 TIJ Technology
After evaluating options, the company made the decision to replace all 38 CIJ units with the REA JET HR 2.0 — a high-resolution Thermal Inkjet printer designed for tough industrial conditions.
Why REA JET HR stood out:
- Robust IP65-rated design: The system handles dusty and particulate-heavy environments exceptionally well. Images from the factory floor show REA JET HR print heads covered in sugar dust and particles — yet continuing to operate reliably without performance degradation.
- Cartridge-based simplicity: Every time a new ink cartridge is inserted, it’s effectively like installing a new printer. No complex fluid systems, pumps, or viscosity management required.
- SLA costs reduced to zero: With the REA JET HR, the company completely eliminated the expensive monthly Service Level Agreements that were previously required for the CIJ fleet.
- Superior uptime and OEE: The dramatic reduction in downtime and maintenance needs created a compelling ROI case strong enough to justify replacing the entire fleet of 38 printers at once.
Measurable Results and Future-Proofing
The switch delivered clear wins almost immediately:
- SLA costs went to zero, delivering immediate and substantial monthly savings.
- Massive uptime improvement: Production lines now run with far fewer interruptions, directly boosting OEE percentages.
- Lower total cost of ownership: Beyond the elimination of SLAs, reduced spare parts and maintenance needs created even more savings.
- Higher print quality: The REA JET HR offers much higher resolution than traditional CIJ, producing crisp, reliable date codes even at high speeds.
- Ready for the future: As the industry shifts toward unique 2D codes for traceability, sustainability information, and anti-counterfeiting, the HR technology can handle complex 2D codes at full production speeds — something CIJ struggled with.
One of the most striking visuals from the implementation is seeing the REA JET HR units performing flawlessly while coated in the very sugar dust that used to cripple the old CIJ systems. This real-world resilience in a harsh environment has been a game-changer.
A Smarter Approach to Industrial Coding
This success story highlights an important lesson for FMCG manufacturers across Africa: in dusty or demanding environments, technology designed for reliability and simplicity often outperforms legacy systems — even if those systems were once considered standard.
The company’s full transition to REA JET HR 2.0 proves that upgrading coding technology can simultaneously reduce costs (including taking SLA expenses to zero), increase reliability, improve print quality, and prepare operations for next-generation packaging requirements like advanced 2D coding.
