摘要： A reflex printing device having multiple print heads mounted at different locations around the circumference of the drum at different “angles” and an encoder disk mounted on the drum to allow for detection of the drum position as a function of time. An image defect due to a misalignment in the print process direction of the output from the multiple print heads is corrected by detection of an encoder position error function subtracted from itself shifted by the angle between the print heads.

摘要： A novel encoder system adapted for use in print architecture at least includes: a codewheel coupled to a rotating print architecture element; a first encoder sensor mounted at a first position relative to the periphery of the codewheel, the first encoder adapted to output a first output signal; a second sensor mounted at a second position relative to the periphery of the codewheel, the second encoder adapted to output a second output signal, and the second sensor positioned substantially 180 degrees relative to the first encoder sensor; and a logic correction circuit adapted to receive the first and second output signals, and for outputting a correction signal with a period that is the average of the periods of the first and second output signals.
