Patent ID: 8424997

Claim:
A recording device comprising: a carriage head; a recording head installed onto the carriage head, the recording head having an array of nozzles that discharges ink on a recording medium; a transfer roller that transfers the recording medium in a direction along the array of nozzles; a control device that controls rotation of the transfer roller; a first detection device that detects a rotation position of the transfer roller; and a second detection device that detects marks printed on the recording medium by the recording head, the control device comprising: a print control device that controls printing the marks on the recording medium in the direction along the array of nozzles from the array of nozzles of the recording head while the carriage head and the transfer roller remain still; a calculation device that calculates a correction amount for use in correction of a rotation angle of the transfer roller according to a difference between an actual transfer amount of the recording medium by the transfer roller at a predetermined rotation position obtained by detection of the marks by the second detection device while the transfer roller is in rotation and a theoretical transfer amount of the recording medium at the predetermined rotation position; and a correction device that corrects the rotation angle of the transfer roller using the correction amount.
