Genuine OEM HP DesignJet T1600dr 36In. Ink and Supplies
The DesignJet T1600dr keeps its ink supply separate from the printhead. HP 730 cartridges hold the ink, and the B3P06A printhead delivers it onto paper. Buying a printhead doesn't refill a low cartridge, even though both products belong to the printer's ink system.
You'll find genuine HP 730 inks at Toner Buzz in smaller and larger sizes for every color, along with the B3P06A printhead. Start with the color that needs ink, then choose its size. Photo black and matte black are distinct inks with their own cartridge slots.
