A printer apparatus comprising one or more printing elements arranged to print on print media in a printzone and a transport path arranged to transport printed sheets from the printzone to an output position, the apparatus further comprising a scanner arranged to scan a printed sheet, and a diverter arranged to selectively divert a printed sheet to the scanner, the scanner being located such that the apparatus may continue to print and transport sheets to the output position during the scanning process.
A printer apparatus comprising one or more printing elements arranged to print on print media located in a print position, the apparatus further comprising first and second media paths respectively adapted to feed media to and away from the print position, the apparatus being arranged to selectively divert a print media sheet from the second media path to a scanning position, the apparatus being arranged to scan the diverted sheet while printing.
A method of monitoring the operation of a printer, the printer comprising a printzone and a first media feed path arranged to transport printed print media from the printzone to an output position, the method comprising:
- printing on a sheet of print media;
- feeding the sheet to an off-line location along a second media feed path;
- and,
- scanning the sheet in the off-line location.
A method of operating a printer apparatus comprising a transport path adapted to transport printed sheets from a printing position to an output position, the apparatus further comprising a diverter arranged to divert a printed sheet from said transport path to an off-line optical scanner arranged to scan the printed sheet, the method comprising:
- diverting a selected printed sheet from the transport path to the optical scanner;
- and, scanning the printed sheet while continuing to print one or more further sheets and to transport those sheets to the output position.
