OCbestjet Product Core Advantages (Compared to Competitors)










1. Precise Compatibility, Superior Stability
Developed specifically for the Epson Workforce Pro WF-R8590DTWF printer, the disposable chip uses imported chip substrate, achieving a 99.9% compatibility success rate, eliminating common issues with competing products such as cartridge recognition and printing interruptions.
The ink formula is highly compatible with genuine EPSON pigment ink, ensuring no clogging or leaks during printing. Tests have shown continuous printing of 500 pages without any issues, while the average number of page failures for similar products is only approximately 300.
2. Large Capacity + High Cost-Effectiveness, Reducing Overseas Procurement Costs
Black ink capacity is up to 402.1ml, and color ink capacity is 192.4ml, 15%-20% higher than similar products in the same category. The cost per page is as low as $0.005.
Wholesale price is only $8 per PC, compared to $12-15 per PC for the same specifications from local European suppliers, saving overseas buyers over 30% in procurement costs. Bulk customization is available, and purchases over 1,000 PCs receive additional discounts.
3. Environmental and Quality Guaranteed, Compliant with European Market Standards
The ink is SGS-certified, contains no heavy metals or hazardous volatiles, and complies with the EU RoHS Directive, allowing direct access to the European market without additional testing.
Each batch undergoes a "triple quality inspection" (raw material testing, sampling during production, and full inspection of finished products). The defect rate is kept below 0.1%, far below the industry average of 1%.
