Print Head for HP OfficeJet Pro Series

This regenerated print head replaces the HP 950 and 951 series cartridges in compatible OfficeJet Pro printers. It fits models including the 8100, 8600, 8610, 8620, 8625, 8630, 8700, 250DW, 251DW and 276DW. The unit operates at 110 volts and is supplied in neutral packaging. Buyers who need a brand-new original HP print head should look elsewhere.

Sustained Printing Behaviour

The regenerated assembly is rated for 100 percent compatibility with the listed printers during continuous operation. Ink flow and nozzle firing remain stable across extended print runs without the overheating that can affect some aftermarket heads. Print quality holds across text and graphics without the banding that appears when a worn head is pushed beyond its duty cycle.

Interface and Voltage Limits

The head connects through the printer's native carriage interface and requires a 110 volt supply from the host device. No separate driver or firmware update is needed beyond what the supported OfficeJet Pro models already provide. Printers outside the listed model range will not recognise the head electrically or mechanically.

Questions about this item

How much power does the print head draw from the 110V supply during continuous printing?

The head operates on a standard 110V supply and is designed for the listed Officejet Pro models; exact wattage is determined by the printer firmware.

Which ink cartridges must be installed for the 950 951 950XL 951XL head to function?

It requires HP 950 black and 951 colour cartridges, or the XL variants 950XL and 951XL, matching the model numbers on the head.

Will this regenerated head work in an older Officejet Pro 8100 alongside original HP heads?

Yes, it is 100% compatible with the 8100 and the other listed models, so it can replace or sit beside original heads without issue.
