Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.

A printing apparatus conveys preceding and following sheets to form an overlapping portion where a trailing edge of the preceding sheet and a leading edge of the following sheet overlap each other at a printing position facing an ejection port surface of a printing unit, and prints the preceding and following sheets by ejecting ink from ejection ports based on a relative movement between the printing unit and the preceding and following sheets. The printing unit delays ink ejection timing for printing the overlapping portion of a sheet located closer to the ejection port surface at a position facing the ejection ports from ink ejection timing for printing a non-overlapping portion where the preceding sheet and the following sheet do not overlap each other in one of the preceding sheet and the following sheet.

Examples described herein include a star wheel mount that includes a support element. The support element includes a first clip element coupled to a first end to engage a first mounting element on a media handler housing, and a second clip element coupled to a second end opposite the first end to engage a second mounting element on the media handler housing. The star wheel mount also includes a star wheel support axle coupled to hold a star wheel in a plane perpendicular to a surface of the media handler housing.

A sheet conveyance device includes a shape detecting portion, and a switch control portion. The shape detecting portion detects a shape of a sheet at a detection position located between a first conveyance member and an image forming position in a sheet conveyance path. The switch control portion, when the first conveyance member is determined to be in an accelerated state where it is accelerated from a stopped state to a driven state, switches an detection interval at which the shape of the sheet is detected by the shape detecting portion, to a first interval that corresponds to a rotation speed of the first conveyance member, and when the first conveyance member is determined to be in a decelerated state where it is decelerated from the driven state to the stopped state, switches the detection interval to a predetermined second interval.
