Abstract
An output voltage of a paper-width detector is input while a carriage is moved leftward in a main scan direction. Whether a mounting position of a test element member in the main scan direction falls within a generally horizontal design basis range is determined based on the position of the carriage and reference information. The position of the carriage in the main scan direction is determined from a signal of a linear encoder when a right edge of the test element member is detected in response to a substantial change in the output voltage of the paper-width detector. Whether a mounting position of the test element member in a substantially vertical direction falls within a vertical design basis range is determined based on the mounting position of the test element member in the substantially vertical direction determined from the output voltage of the paper-width detector and the reference information.
