Unsuccessful roll load

The paper can not be loaded successfully, this is caused by the paper sensor being dirty. Check that the printhead is not leaking ink onto the sensor, check that the service station isn’t full of ink and that the brush is not covered in ink. The paper detector sensor is located on the right side of the printhead. When it gets dirty it will cause the printer to unload the roll.
