Abstract
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.
Claims15
A method comprising:
- 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;
- 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 device comprising:
- a power monitor to detect 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;
- a locator to detect a location of the printer carriage at the time of the detected power increase;
- and
- a damage determiner to determine, based on the detected location of the printer carriage, whether the print medium is damaged.
A program which, when executed on a computer, causes the computer to carry out a process comprising:
- 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;
- detecting a location of the printer carriage at the time of the detected power increase;
- and
- determining, based on the detected location of the printer carriage, whether the print medium is damaged.
