Hi. I have the above printer connected to my iMac and it has been working flawlessly for months. I have one issue though. When the printer is running low on ink, the maintenance light blinks, indicating low levels. But, it doesnt tell what ink cartridge is low, and since i dot want to go all out and change them all, i need to know how to view levels. On my Mac, it only says information not available for supply levels, and as far as I know, there is no way to check on the printer itself. So my question is this: Does anybody know how to view the ink levels, either on the printer or my iMac?
