DIAGNOSIS A steady or flashing orange light is a general error. Often it's a paper jam, an ink cartridge issue, or a cover not fully closed.
FIX Check all covers are firmly shut, especially the rear output cover. Open and close the ink cartridge access door. Ensure all cartridges are correctly installed and not empty. Remove any paper from all trays.
IF THAT DIDN'T WORK Unplug the printer from the wall for 60 seconds. This can clear a temporary system lock. Plug it back in.
HEADS UP If the light flashes orange 15 times, it's a specific error. Count the flashes. That code points to the exact problem.
