Laser Tek Services 4-Pack Black Toner Refill Kit for HP 78A CE278A

Four-pack refill kit for HP 78A printers

This Laser Tek Services kit contains four bottles of black toner designed to refill HP 78A CE278A cartridges. It supports the LaserJet Pro M1536dnf, M1537dnf, M1538dnf, M1539dnf, P1566 and P1606dn series. Each refill yields standard 5% page coverage for consistent monochrome output.

Refillable cartridge design reduces waste

Users can recycle and reuse each original HP cartridge up to three times with this kit. The process avoids single-use disposal and lowers the cost per printed page. No chip replacement or hardware modification is required during the refill procedure.

Bottles include pour spouts for clean fills

The packaging provides four individual toner bottles with integrated spouts to minimise spills. No additional tools, funnels or software utilities are bundled. The kit suits offices that prefer manual refilling over purchasing new aftermarket cartridges.
