What doe the message marker supply low mean?

HP Officejet Pro 6970

What does the message marker supply low mean? A couple of the ink cartridges are low on ink, but I don't know what a marker supply is.

Hi @caweav


Welcome to the HP Support Community. I'd be happy to assist you with the "Marker Supply Low" error. 


Check inks levels using these steps - On the printer control panel, touch the Ink Level Indicator icon . The control panel displays estimated ink levels. Consider replacing cartridges marked  or  when print quality becomes unacceptable.


If the ink levels are fine, try these steps to reset the printer - 


1) Take out the cartridges.

2) Unplug the power cord from the printer & wall.

3) Wait for 30 seconds. 

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector.

5) Insert the cartridges back into the printer.


Try updating your Mac using these steps - How to update the software on your Mac


Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 


Hope this helps! Keep me posted.
