Error code 26:10 Error code 27:10 is related to the ink system, either printhead is faulty or the
service station is faulty. There might be something stuck in the carriage, check that the printhead can move up and down the rail and that no paper is stuck. Also check Carriage PCA, Trailing Cables You would need to call for an engineer to get your printer service.

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.
