My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
What is the error message that you get?
You can reply to me here by typing in the box below please.
Yes, sorry for the delay.
Have you tried a new HP 951 ink cartridge?
Try this and power off the printer then back on.
Gently bend the tab away from the cartridge.
Be careful not to bend the tab out more than 1.27 cm (0.5 in). Moving the tab too far might damage the cartridge or cause the tab to break off.
Reinsert the cartridge into the carriage until it snaps into place, and then close the cartridge access door.
Check the printer control panel for any error messages.
no problem, take your time.
sorry for the delay,
Here is an image for reference>
okay, remove and then reinsert the cartridge and make sure it snaps in place.
Then follow these steps to reset the printer.
Press the Power button to turn on the product.
With the printer turned on, disconnect the power cord from the rear of the product.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
Reconnect the power cord to the rear of the product.
If the product does not turn on by itself, press the Power button to turn it on.
no, I have not seen any that did not accept genuine HP cartridges.
Hello, Pete another expert here...
Try running a few print head cleaning cycles using the printer's service menu.
If that doesn't help then some disassembly and manual cleaning will be required.
You will need to remove the printhead from the printer and clean it in an alcohol solution.
This can be tricky and quite messy.
Given the low cost of new printes ($50) they are usually just replaced.
Do you have a link to what you are referring to?
Randy, I am being honest with you, and I am very disappointed that you would think otherwise.
I am a user of this site just like you.
I asked for a link but you haven't provided one because either you have mis-read it or you have read some incorrect information somewhere.
HP have not done anything to stop their printers from working. They have NOT changed a chip to make the ink cartridges incompatible.
HP still make genuine compatible ink cartridges for the PRO 8600 printers.
