The printer won't come out of Paused printing - says ink is low. However, the manual does not say how to move the block of cartridges from the dock so that I can get access to change an ink. Past printers I have been able to do this via the computer but it seems I have to do this via the actual printer? I am told I have to select Setup but all I can bring up is Wi-fi setup which is already done!. Thanks
