Epson T9661 WF-M5299/5799 Series Ink Supply Unit XXL Black (C13T966140)

Ultra-High Capacity Monochrome Printing Solution

The Epson C13T966140 delivers exceptional printing volume through its massive 40,000-page capacity design. This XXL supply unit employs advanced pigment-based ink technology for sustained professional output. Furthermore, the specialized formulation ensures consistent black density throughout the extended printing cycle.

Enterprise-grade pigment particles provide superior document quality and long-term archival stability. Additionally, the T9661 incorporates enhanced flow management systems that prevent ink settling during extended storage periods. Each supply unit undergoes extensive testing to guarantee reliable performance across the full capacity range.

Professional Output and Document Excellence

Precise black text reproduction defines every document printed with the C13T966140 cartridge. The high-concentration pigment formulation achieves optimal density measurements that surpass commercial printing standards. Moreover, printed documents exhibit exceptional contrast ratios and maintain professional appearance under various environmental conditions.

Consistent ink delivery characteristics ensure uniform print quality throughout the cartridge’s complete 40,000-page lifespan. The Epson T9661 maintains stable black saturation from initial installation to final replacement. Consequently, users experience reliable document quality across months of continuous printing without performance degradation.

Enterprise Cost Management and Efficiency

The C13T966140 dramatically reduces operational expenses through its ultra-high capacity design and extended replacement intervals. Cost per page decreases to approximately $0.005 for standard business documents. Subsequently, large organizations achieve substantial savings during high-volume monochrome printing operations.

Extended operational periods minimize workflow disruptions and eliminate frequent maintenance requirements. The XXL capacity enables continuous operation for several months without cartridge replacement. Therefore, productivity maximizes while administrative overhead decreases significantly compared to standard capacity alternatives.

Advanced System Integration and Monitoring

The T9661 integrates seamlessly with WF-M5299/5799 series printers through precision-engineered connection systems. Automated alignment mechanisms prevent installation errors during replacement procedures. Subsequently, intelligent recognition technology calibrates ink parameters and optimizes print settings automatically.

Sophisticated monitoring systems provide detailed capacity tracking and predictive analytics for replacement planning. The system delivers early warning notifications well before ink depletion occurs. Therefore, maintenance scheduling becomes highly predictable and efficient for enterprise printing environments.
