Firmware note: DesignJet firmware updates can reject cartridges with non-HP chips. Our HP 730 cartridges are rebuilt from original HP shells and keep the HP chip; keep automatic firmware updates off. The 730 series uses a separate HP 730 printhead (P2V27A), replaced only when the printer reports it worn.

HP 730 Ink: Common Questions

Is 300 ml the only size?

HP also sells 130 ml HP 730 cartridges (P2V62A–P2V67A). The 300 ml size we stock fits the same slot and costs less per milliliter, so it is the better buy for a printer in regular use.

Which printers use HP 730 ink?

HP DesignJet T1600, T1600dr, T1700, T1700dr, T2600 and T2600dr (including PostScript models). Our Find Ink by Printer page has a guide for each model.

Are HP 730 and HP 727 interchangeable?

No. HP 727 fits the older T920/T930/T1500/T1530/T2500/T2530; HP 730 fits the T1600/T1700/T2600. The cartridges are keyed differently. See our HP 727 page for the older models.

Will remanufactured cartridges void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, HP cannot void your printer warranty just because you used third-party ink or toner. If a cartridge from us ever isn't recognized or prints poorly, contact us and we'll replace or refund it under our 1-year guarantee.
