for the error code 42:10 when initializes and printing, it tells there may be a paper or carriage jam, it also refers to a Scan Axis Motor Failure (electrical problem caused by difficulties moving the carriage – too much force needed to move it due to obstructions, high friction or restrictions).


In simple terms, ANY restriction or obstruction preventing the carriage from freely moving will cause the printer to stop working and show any of these errors.
The best and easier way to diagnose the problem is to locate the spot where the carriage stops when the printer shows the error (in case of no real paper jam). Most likely the main possible cause of the issue will be there.
If service onsite is needed, a proper diagnosis of the failing component is indispensable. Even if one component looks like the obvious cause of the problem, it is important to check other Scan Axis components.
