Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate registration errors in a printing system that carries a plurality of medium sheets placed on a belt.SOLUTION: The system includes steps for identifying a first displacement amount of a sheet carrying device and a second displacement amount of the sheet carrying device when the sheet carrying device carries a medium sheet passing through first and second printheads, respectively, for the image processing of a predetermined location of the medium sheet. A time for operating the second printhead is adjusted based on a difference between a first sheet carrying device offset and a second sheet carrying device offset to provide color registration between ink drops of the first printhead and second printhead on the medium sheet.

Abstract: PROBLEM TO BE SOLVED: To provide a sheet positioning system, in particular, for a printer having an inexpensive system of small mass movement, in particular, for a high-speed printer, capable of performing both of the skew correcting operation for the sheet and the repositioning operation for side positioning the sheet in the same integral system.
SOLUTION: Both of two nips 17A, 17B mounted at an interval for feeding a sheet can be driven only by one main driving motor M1, two sheet feeding nips mounted at an interval are moved with relative difference in angle inexpensively with very small power, and the skew correction is performed in a differential driving system to realize the skew correction movement of the desired amount of sheets. The mass of elements moving in parallel in the lateral direction is reduced over a wide range for lateral sheet positioning.

Abstract: PROBLEM TO BE SOLVED: To provide an improved alignment method and a device corresponding to non-uniformiy of an edge shape of a belt.SOLUTION: The method detects a first lateral interval of an edge of a belt loop supported by rollers in an apparatus using a first sensor to find an amount of a difference amount of the alignment of the edge of the belt loop relative to a known alignment position. The method also detects a second lateral interval of the edge of the belt loop in the apparatus relative to the known alignment position using a second sensor, and determines the non-linear shape of the edge of the belt loop based on the second lateral interval of the edge of the belt loop detected by the second sensor. Moreover, the method corrects the difference amount of the alignment detected by the first sensor based on the non-linear shape of the edge of the belt loop to generate a corrected difference value of the alignment and adjust the current lateral position of the belt loop in the apparatus relative to the known alignment position based on the corrected difference value of the alignment.
