I changed the ink cartridge and now get "There is a problem with the printer or ink system.

[Jaye553]

the message says "turn the printer off and then back on and if problem persists contact HP". 

Of course it persists!  Help!

Hi @Jaye553,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

When you encounter a message on your HP Officejet Pro 8600 E-All-In-One Printer instructing you to "turn the printer off and then back on," it's typically a general troubleshooting step to address minor issues. Here are some steps you can follow.

Turn Off the Printer:

• Press the power button to turn off the printer.
• Wait for about 10-15 seconds to ensure that the printer is completely powered down.

Turn On the Printer:

• Press the power button again to turn the printer back on.

Check for Paper Jams:

• Make sure there are no paper jams in the printer. Even a small piece of paper can cause issues.

Inspect for Obstructions:

• Check for any obstructions in the paper path, such as torn pieces of paper or foreign objects.

Reset the Printer:

• Some printers have a reset option in their menu. Check your printer's user manual for instructions on how to perform a reset.

Update Firmware/Drivers:

• Ensure that your printer has the latest firmware installed. Visit the HP website and check for firmware updates for your specific printer model.

Verify Connectivity:

• If your printer is connected to a network, ensure that the network connection is stable. If it's a USB connection, check the cable and try using a different USB port.

I hope this helps. 
 

Take care and have a good day.
