Epson T05A4 WorkForce Pro WF-C879R Yellow XL Ink Supply Unit

The Epson T05A4 delivers enterprise-grade yellow ink performance for high-volume commercial printing operations. This extra-large ink supply unit produces an exceptional 20,000 pages with consistent color accuracy and reliability.

Advanced Ink Supply Technology

The T05A4 utilizes Epson’s innovative ink supply unit design that maintains consistent flow throughout its extended lifespan. This system prevents air bubble formation that can compromise print quality. Furthermore, the pressurized ink delivery ensures uniform distribution across all print heads.

The unit incorporates precision-engineered valves that regulate ink flow automatically. Additionally, the sealed supply chamber protects ink integrity during extended storage periods between high-volume print runs.

Ultra-High Capacity Design

With its remarkable 20,000-page yield, the Epson T05A4 transforms operational efficiency in demanding print environments. This capacity represents four times the output of standard cartridges. Consequently, the extended yield minimizes replacement frequency and reduces per-page operational costs significantly.

The supply unit’s large reservoir design maintains consistent ink pressure throughout its lifespan. Therefore, print quality remains uniform from the first page to the final output.

Professional Color Accuracy

The T05A4 features specially formulated DURABrite Ultra pigment ink optimized for vibrant yellow reproduction. This technology ensures accurate color matching across extended print runs. Moreover, the pigment-based formula provides exceptional fade resistance for archival document requirements.

The ink supply unit integrates seamlessly with other color units to produce comprehensive color gamuts. Additionally, the precise color formulation maintains consistency across different paper types and weights.

Enterprise Installation System

The Epson T05A4 installs through a secure locking mechanism designed for frequent handling in commercial environments. The unit features clear ink level indicators for visual monitoring. Furthermore, the ergonomic design includes integrated handles for safe transport and installation procedures.

The supply unit’s smart monitoring system communicates detailed usage statistics to the WF-C879R printer. Consequently, facility managers receive accurate consumption reports for cost tracking and inventory planning.

Streamlined Maintenance Protocol

The T05A4 incorporates self-sealing connections that prevent ink leakage during replacement procedures. The unit’s modular design allows individual color replacement without affecting other ink supplies. Moreover, the foolproof installation system prevents incorrect placement that could damage printer components.
