HP 70 Gray 130-ml Cartridge

This genuine HP 70 Vivera ink cartridge supplies 130 ml of gray dye-based ink for HP DesignJet Z2100, Z3100, Z3200, Z5200 and Z5400 series printers. It is intended for professional graphics users who need consistent neutral tones in photographic and proofing output.

Simple drop-in installation

The cartridge clicks into the designated gray slot without tools or firmware steps. The only common issue is forgetting to remove the protective seal before insertion, which blocks ink flow and triggers a replacement alert.

130-ml volume for high-volume proofing

The 130-ml fill supports extended print runs on 24-inch and 44-inch DesignJet models, delivering over 200 years of display permanence on HP creative media. It runs out when the printer reports the gray channel empty, requiring a new cartridge to continue.
