Provided is a print data correction method that is executed by a printing device. The print data correction method includes: printing a first correction chart with a printer that performs printing; obtaining a first correction value based on the printed first correction chart; printing a second correction chart based on the first correction value with the printer; obtaining a second correction value based on the printed second correction chart; and correcting, based on the second correction value, print data to be printed by the printer.

In one example of the disclosure, subject audio data, indicative of a subject audio captured via a transducer during an operation of a subject electromechanical device, is accessed. Baseline audio data, indicative of a baseline audio captured during an operation of a baseline electromechanical device, is accessed. An electronic file that includes differences between the subject audio data and the baseline audio data is created.

There is disclosed a device, method and program, wherein the method comprises detecting a power increase, during which power usage increases by at least a threshold amount over an expected power usage during movement of a printer carriage over a print medium along a scan axis. The increase method further comprises detecting a location of the printer carriage at a time of the detected power usage increase and determining, based on the detected location of the printer carriage, whether the print medium is damaged.

A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit, and a controller. The decoloring unit decolors the image on the sheet conveyed through the sheet conveying unit. The decoloring unit is positioned downstream of the scanner in a sheet conveying direction. A distance along the sheet conveying direction between the scanner and the decoloring unit is shorter than a length of a first predetermined sheet size and longer than a length of a second predetermined sheet size. A controller determines whether the sheet conveyed by the sheet conveying unit is the first predetermined sheet size or the second predetermined sheet size. The controller performs a mode limiting process if the sheet size is determined to be the first predetermined sheet size.
