there is a sensor in the drum unit that measures/sensors toner density on the drum. the sensor is usually dirty and needs a clean. there could be a number of causes so a technician needs to be called.

That is due to the clear plastic strips inside the printer, the one that run behind the cartridge holder, being dirty or damaged.
This plastic strip with black marking on it, is used to tell the printer where the cartridges actually are.
Unfortunately it could also be the sensor that reads this strip being damaged.
Inspect the strip with a bright torch to see if any ink or dirt is on this strip, use a bright torch when doing so, it makes it much easier. Also check behind the cartridge holder for any torn bits of paper that could be jammed in it.
Make sure the printer is unplugged from the power during this!!
I hope this helps

* E03 error means that it may have something to with a clogging of the paper feed sensor.
try to clean every theing in the paper path and check if there is no sensor broken or bend or stuck
