Nestink C9345 Ink Maintenance Box for Epson EcoTank and WorkForce Printers
Product description
When a compatible Epson printer needs a replacement maintenance box, the Nestink C9345 is made for that specific service part. It is listed for a range of EcoTank and WorkForce models, including several ET, WF, EC-C, and ST-C printers. Choosing a model-matched replacement is a different approach from buying general ink supplies: it focuses on keeping the printer’s maintenance system equipped with its designated part.
Key takeaways

The C9345 maintenance box is a compatible replacement identified by the codes C9345, PXMB9, and C12C934591. Its listed printer fit includes EcoTank ET-16600, ET-16650, ET-5800, ET-5850, ET-5880, ET-8500, and ET-8550, WorkForce WF-7310, WF-7820, and WF-7840, and EcoTank Professional EC-C7000, ST-C8000, and ST-C8090. Matching the printer’s model to this list helps narrow the search to a replacement intended for that equipment.
Buyers describe it as a useful replacement, while feedback on compatibility is mixed. That makes checking the exact printer model against the supported list a practical step before choosing this part. The product is made with long-staple cotton for ink absorption and includes an upgraded chip, according to the product details. These features are intended for maintenance-box use rather than routine ink replenishment.



How to use it
Use this part as a replacement maintenance box in one of the listed compatible printers. The product information says an installation manual is provided, so the printer-specific instructions are the right guide for fitting it. Following those instructions keeps the replacement process focused on the intended service component, rather than treating the box like an ink cartridge that supplies color for printing.

The package details also list disposable gloves and a PE sealed bag. These support handling and containing the maintenance part during replacement. For a straightforward selection, identify the printer’s model name first, then compare it with the compatibility list and the C9345/PXMB9/C12C934591 part references.
Best use cases



This replacement is suited to maintaining a supported Epson inkjet printer when its maintenance box needs to be changed. It covers both home-office and work-focused printer families in the listed range, including EcoTank models and WorkForce models. For example, an owner of an ET-5850 or WF-7840 can use the model list to check whether this C9345 part is the relevant replacement before starting a maintenance task.
If the priority is replenishing printing ink, an ink cartridge or ink bottle serves a different purpose. The C9345 is the maintenance-box option: choose it when the printer calls for this component, not as a substitute for ink supplies. It suits you if you want a compatible replacement identified by the C9345 reference and your exact printer appears in the supported-model list.
