In example implementations, a method, a device, and a program are provided. The method includes detecting a power increase movement of a printer carriage. A location of the printer carriage is detected at a time of the detected power increase. Based on the detected location of the printer carriage, determine whether the print medium is damaged. The device includes a power monitor to detect a power increase during movement of a printer carriage. A locator detects a location of the printer carriage at the time of the detected power increase. A damage determiner determines, based on the detected location of the printer carriage, whether the print medium is damaged. The program detects a power increase during movement of a printer carriage. Location of printer carriage is detected at time of detected power increase. Based on detected location of the printer carriage, it is determined whether the print medium is damaged.

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.

An enhanced paper for printing, including a substrate, an ablation resistant coating applied to the substrate, wherein the enhanced paper is ablation resistant so that it is not damaged by a light beam that illuminates enhanced paper with a fluence that ablates ink or toner but would damage standard printing paper that is made from cellulose fiber and is non-ablation resistant; and wherein the enhanced paper has physical properties of the standard printing paper for printing with laser printers and ink printers.

A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit positioned downstream of the scanner, a user interface, and a controller. The user interface includes a resolution setting section configured to receive input for setting the resolution of the image to be scanned by the scanner, and a processing mode setting section configured to receive input for setting whether to execute scanning processing by the scanner and for setting whether to execute decoloring processing by the decoloring unit. The controller is configured to control contents of the user interface and to perform a mode limiting processing so that when one of the scanning processing and decoloring processing is set to be executed, the other of the scanning processing and decoloring processing cannot be set to be executed.

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.
