Patent ID: 7056048

Claim:
A system for ensuring that printed matter is properly printed on a print medium comprising: a printer having a feeding device for facilitating the feeding of said print medium into said printer and first and second print heads, said feeding device having a top portion and a bottom portion, said print medium being fed in between said top portion and said bottom portion; and a plurality of first detecting devices disposed along a length of said bottom portion of said feeding device and a plurality of second detecting devices disposed along a length of said top portion of said feeding device; said print medium having a plurality of signaling components, each of said first and second detecting device being able to detect the presence of each of said signaling components when each of said signaling components is in proximity to said detecting device; wherein said system determines a first feed orientation of said print medium based on either an order in which each of said first detecting devices detects the presence of a respective one of said signaling components or an order in which each of said second detecting devices detects the presence of a respective one of said signaling components when said print medium is being fed into said printer between said top and bottom portions and wherein said printer causes said printed matter to be printed in a proper location and in a proper orientation on said print medium based on said first feed orientation using said first print head if said first detecting devices detect said signaling components and said second print head if said second detecting devices detect said signaling components.
