Hi @Barebarigrm,

Welcome to the HP Support Community

I'd like to help!

I understand you are receiving a supply system error

Try the below suggestions -

Step 1: Check the ink cartridges for leaks

Replace any ink cartridges that leak.

  CAUTION:

Do not use leaking ink cartridges.

To find your cartridge number and to purchase ink or toner supplies, go to HP Store or a local retailer. Make sure you are using the correct genuine HP ink or toner supplies for your printer. HP cannot guarantee the quality or reliability of non-HP cartridges or refilled HP cartridges. To check the authenticity of your cartridges, go to the HP anti-counterfeit webpage (in English).

If you have a defective cartridge or printhead, it might be under warranty. To check the warranty on your ink or toner supplies, go to Printer and Page Yield Overview, and then review the limited warranty information for your supplies.

Open the door to access to the ink cartridges.

Wait until the carriage stops moving before you continue.

Remove an ink cartridge, and then inspect the ink cartridge for leaking ink.

If the ink cartridge leaks, replace the ink cartridge. If the ink cartridge is not leaking, insert the ink cartridge into its slot.

Repeat these steps for the other three ink cartridges.

Close the ink cartridge access door.

If the error message persists, continue to the next step.

Step 2: Reset the printer

Resetting the printer might clear the error message.

With the printer turned on, disconnect the power cord from the printer.

Unplug the power cord from the power source.

Wait 60 seconds.

Reconnect the power cord to a wall outlet and to the printer.

NOTE:

HP recommends plugging the printer directly into a wall outlet.

If the error message persists, continue to the next step.

Step 3: Check the carriage for a printhead latch

Open the door to access to the ink cartridges, and then determine if the carriage inside the printer has a printhead latch.

Example of a carriage with a latch

If your carriage has a printhead latch, continue to the next step.

If your carriage does not have a printhead latch, skip to Service the printer.

Step 4: Reseat the printhead up to three times

To clear the error message, you might need to reseat the printhead up to three times.

Open the door to access to the ink cartridges.

Wait until the carriage stops moving before you continue.

Unplug the power cord from the rear of the printer.

  WARNING:

You must disconnect the power cord before reaching inside the printer.

Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch to lock the printhead into place.

Close the ink cartridge access door.

Reconnect the power cord to the rear of the printer, and then check the control panel for the error message.

Sometimes error messages persist after inserting the printhead. If the error message persists, repeat the steps to reseat the printhead up to three times
