Patent ID: 8201906

Claim:
A method of addressing a group of a first number (K) of nozzles of a printhead, the nozzles of said group being staggered and being arranged according to a spatial order with respect to a first transversal translation direction of the printhead, each nozzle of said group having an own unique address, comprising: A) dividing said group of nozzles into a second number (L) of sequential subgroups of nozzles, corresponding to a second number (L) of addressing spaces, said addressing spaces consisting of a same third number (M) of addresses, wherein the first of said addressing spaces comprises the address of the first nozzle in said spatial order, B) preparing an addressing scheme by cyclically and progressively selecting addresses from said addressing spaces, starting from the address corresponding to the first nozzle in said spatial order and following said spatial order, C) when said printhead translates transversally along said first transversal direction, addressing the nozzles of said group according to the addressing scheme of step B; wherein said first number (K), said second number (L) and said third number (M) are integers, wherein said second number (L) is not greater than said first number (K), wherein said third number (M) is the integer equal to or immediately greater than the quotient between said first number and said second number, and wherein the last addressing space of said addressing spaces comprises at least one fake address that does not correspond to a nozzle of said group if the remainder of the division of said first number (K) by said second number (L) is not zero.
