What do the flashing orange lights or 'P' error codes (e.g., P02, P07) on my Canon PIXMA MG3620 indicate?

Flashing orange lights and 'P' error codes on your Canon PIXMA MG3620 are service errors. P02 often indicates a carriage error, possibly due to an obstruction or faulty sensor. P07 typically points to a full waste ink absorber or a general print issue. For P02, check for paper jams or foreign objects inside the printer and perform a power cycle. For P07, while it can indicate a full waste ink absorber which requires service, sometimes a power cycle (unplug for 5 minutes, then plug back in) can temporarily resolve it. If the error persists, especially P07, it often requires professional service or contact with Canon support.
