Printing press with multiple inking units

A method of operating a printing press that includes a plurality of inking systems, which cooperate with at least one impression cylinder, each of the inking systems including a print roller and at least one additional ink-transfer roller, each of which includes a roller body, at front sides of which a first and a second end shaft journal is disposed, at least one roller-bearing device, in which the print rollers and the ink-transfer rollers are mountable outside the inking systems in roller-bearing positions, including at least one roller-bearing position in which one of the rollers can be set up for a subsequent print job, and a transfer element, via which at least the print rollers or the ink-transfer rollers are transportable substantially in radial directions thereof between the roller-bearing positions and the inking systems, with the roller-bearing device including a holding element in the at least one roller-bearing position for at least temporarily holding the roller by either the first or the second end shaft journal thereof alone, the holding element including a lever arm, which is pivotably mounted on the roller-bearing device, and a first lever and a second lever, with first ends of the first lever and the second lever being connected to each other by a swivel joint, the first lever being rotatably connected to the lever arm, and the second lever being rotatably connected to the roller-bearing device, said method comprising:

• transporting the print rollers or the ink-transfer rollers, substantially in the radial directions thereof, between the roller-bearing positions and the inking systems,
• including at least temporarily holding the roller in the roller-bearing device by the first or the second end shaft journal thereof with the holding element.
