138A Black Laser Jet Toner Cartridge Compatible for HP 3101fdw - High

In this review the SERENDIPITS 138A black toner cartridge is evaluated for office users who need reliable monochrome output from HP Laser Jet Pro MFP 3101fdw, MFP 3101sdw, 3001dw and 3001fdw printers. The bottom line: it is a sensible replacement when capacity and cost matter, delivering crisp, smudge-resistant pages and easy installation thanks to the built-in chip. For small offices or home offices that print regularly, the high page yield and consistent black density are the single biggest reasons to consider these cartridges.

Key Features

• Compatibility: Works with several HP Laser Jet Pro models including MFP 3101fdw, MFP 3101sdw, 3001dw and 3001fdw so a single spare fits multiple machines.
• Built-in chip: Each 138A cartridge includes a chip so there is no need to transfer components from an old cartridge, simplifying replacement.
• High page yield: The 2-pack delivers up to 1,800 pages per cartridge at 5 percent coverage, providing long run times and fewer interruptions for replacement.
• Stable print quality: The specially formulated toner produces clear, natural black text with good smudge resistance suitable for office documents.
• Leak prevention: Manufactured with attention to sealing and materials to minimize toner leaks during installation and use.

Who It's For

Small offices, remote workers, and anyone running HP Laser Jet Pro MFP 3101fdw or the listed sibling models will find these cartridges a practical choice when monthly print volumes are moderate to high and cost per page matters. The built-in chip and compatible fit make them convenient for IT managers who support multiple identical printers.

Users who require OEM support coverage or who need ultra-high precision for professional graphics should consider OEM cartridges or manufacturer-recommended supplies instead, as third-party toners aim to balance value and quality rather than match every OEM specification.
