Thermal 3 Errorcode: [01029] Timeout waiting to learn focus


Service Information	This error occurs when the auto focus system takes too many drum rotations to establish a plate profile table which can be tracked with minimum focus error during a 'focus learn' or a 'focus adjust' operation.
	Minimum focus error is established when the error does not exceed +/-10 microns more than 10 times in a single drum rotation. This minimum focus error condition must be established within a maximum of 10 drum rotations or this error is generated. In a typical normal scenario, the focus error falls to less than 5 microns on any sample period of 100 us and remains steady within 3 drum rotations.
Operator Action	Check plate loading, proper media settings, attempted imaging over clamps or other invalid plate areas.
Causes	Inability to establish minimal error during 'focus learn' or 'focus adjust'
