It's a firmware error.
Solution one: Restart the product
Disconnect the Universal Serial Bus (USB) cable from the back of the product, but leave the product turned on.
Open the cover of the product and remove the print cartridges.
Close the cover and wait for the Insert Ink Cartridges message to display.
Disconnect the power cord from the back of the product and wait for one minute.
Reconnect the power cord. If the product does not automatically turn on, press the Power button.
Open the cover and reinsert the print cartridges.
Close the cover. If prompted, print a calibration page.
Reconnect the USB cable, and try to print a print job from the computer.
The next step would be a partial reset, which your printer unfortunately doesn't have.
Instead, you can try clearing the derivative and reseting the NVM RAM.
To do that:
Press and hold OK and Cancel while plugging in the power cord.
If the error code does not display after the reset, print a test page to ensure that the issue is resolved.
If the error code does display, the product needs to be replaced.
