Thank you for your question, unfortunately as we do not sell machines we are not technically trained I would advise that you contact your manufacturer.

Thank you for your query,

Both of these machines take the same cartridges.

Please see the link below.

The HP Officejet Pro 8600 Plus e-All-in-One printer is classed as a different printer model to the Officejet Pro 8600 e-All-in-One printer even though these two devices use the same cartridges. The HP 950 / 950XL and HP 951 / 951XL ink cartridges are compatible with both the HP Officejet Pro 8600 and 8600 Plus printers.

Yes, we do supply single black ink cartridges for the HP Officejet Pro 8600 Plus e-All-in-One printer which are listed below the multipacks on this page. We currently stock a standard capacity black HP 950 ink cartridge or a high capacity black HP 950XL ink cartridge for use in the Officejet Pro 8600 Plus printer. Please see the direct links below to either of these single black ink cartridges:

No, the HP Officejet Pro 8600 Plus e-All-in-One printer has a separate printhead into which the cartridges are installed. Unfortunately, we can only supply you with the HP Officejet Pro 8600 Plus ink cartridges. If a replacement printhead is required you may need to contact HP for this item as it's more of a specialist part and might require an engineer to fit it.

Unfortunately, we only stock the HP Officejet Pro 8600 Plus e-All-in-One ink cartridges at this time so we'd advise you to contact HP directly for printer parts such as the printhead carriage.

All of the ink cartridges listed on this page will work reliably in your HP Officejet Pro 8600 Plus e-All-in-One printer, including the HP 951XL high capacity colour ink cartridges. The HP 951XL high capacity colour cartridges are the same physical size as the HP 951 standard capacity colour cartridges, they just contain a larger volume of ink. Therefore, you should be able to install your 951 XL colour cartridges in the same cyan, magenta and yellow colour slots as the HP 951 cartridges without any problems. Please refer to your Officejet Pro 8600 Plus printer manual for further instructions on cartridge replacement.

Any of the packs / cartridges listed on this page are compatible with the HP Officejet Pro 8600 Plus e-All-in-One printer. The pack of four cartridges contains the HP 950XL high capacity black ink cartridge and the HP 951XL high capacity cyan, magenta and yellow ink cartridges for your printer.

We currently supply two packs of cartridges for the HP Officejet Pro 8600 Plus e-All-in-One printer. Our 4 colour multipack includes four separate HP 950XL and HP 951XL cartridges for the colours black, cyan, magenta and yellow. The price shown is the price of buying the pack with all four colours inside even though the cartridges are in separate colours when taken from the pack. You'll also receive 75 x sheets of A4 printer paper with our HP Photosmart Pro 8600 Plus multipacks. Please see: http://www.cartridgesave.co.uk/CR712AE-CN045AE-PACK.html

Yes, the black cartridges can be bought separately and replaced individually when they run out. However, it's likely that because your printer is a colour inkjet that uses four separate cartridges you'll need to have all the cartridges installed with some ink in them to print.
