A method of operating a printer compares print job parameters for a current print job to be printed by the printer to a database of print job parameters for previously performed print jobs to identify media issues that may be caused by printing the current print job at a nominal printhead/media transport path distance. The gap between the printheads and the media transport is adjusted for identified media issues. Additionally, the method evaluates the image data content of the current print job to identify media issues that may arise from the printing of each sheet in the print job. If media issues are identified from the image data content, then the gap between the printheads and the media transport is further adjusted for sheets corresponding to the identified media issues caused by the image data content. An inkjet printer capable of being operated in this manner is also disclosed.

There is provided a recording device including a transport section that transports paper along a support surface; a recording section; a determination region setting section; a liquid volume ratio calculation section; a determination section; and a recording position adjustment section that, when the determination section determines that the average value is larger than the threshold, adjusts a distance of the recording section from the support surface to a distance which is longer than a case in which the average value is not larger than the threshold.

A recording apparatus includes a carriage, a medium support member, a gap switching unit, and a maintenance unit. The carriage includes a recording head configured to record on a medium. The medium support member is provided at a position facing the recording head and is configured to support the medium. The gap switching unit is configured to switch a gap between the medium support member and the recording head. The maintenance unit is configured to perform maintenance on the recording head. The gap switching unit and the maintenance unit are driven by a common motor.
