A printer having multiple processor cores, and a firmware rewriting method for the printer, enable rewriting firmware in a short time. A first rewrite controller controls rewriting the firmware of the first core by the boot program of the first core; a second rewrite controller controls rewriting the firmware of a second core, which is one of the multiple cores other than the first core, by the boot program of the first core; and a reset unit resets the printer after rewriting the firmware of the first core and the firmware of the second core by the boot program of the first core ends.

Method of rewriting printer firmware, and printer

A hybrid processing device having printheads that records on a check conveyed through a medium conveyance path includes a first sensor that detects insertion of a check from the recording medium entrance of the medium conveyance path, a second sensor that detects discharge of the check from the recording medium exit of the medium conveyance path, and a third sensor that detects presence of a check between the first and second sensors. It is determined that the recording medium has been removed from the conveyance path, when the recording medium detectors change from a first state, in which at least one of the recording medium detectors detects that the recording medium is present, to a second state, in which none of the recording medium detectors detect that the recording medium is present.
