Abstract: A printing apparatus includes an apparatus body, a carriage, an encoder, a detection target member, a detector, and circuitry. The encoder detects an amount of movement of the carriage in a main scanning direction. The target member on the carriage has a cutout portion halfway in the main scanning direction. The detector on the body detects the target member. The circuitry controls a position setting operation for setting a home position of the carriage based on a detection result of detection or non-detection of the target member. The circuitry measures an output pulse of the encoder from when the detection result changes from detection to non-detection until when the detection result changes from non-detection to detection, and determines whether a measured value of the output pulse is equal to or greater than a predetermined value set based on a width of the cutout portion in the main scanning direction.

The stamping component may be formed of a top part with a handle element and a bottom part with a cushion-receiving element. The stamping insert may be connected so as to move synchronously via a reversing mechanism having a slide track in the bottom part via a shaft or trunnion to the top part. In the resting position a text plate mounted on the stamping insert may abut against an ink pad soaked with ink in the cushion-receiving element. The metallic elements can be attached from the outside onto the top and bottom parts formed from plastic material and these are fixed via a fastening system of the upper and lower parts. The metal part of the bottom part is fixed on a surface of the plastic part.

Abstract: A method and a device as provided for printing a large surface which is situated, in particular, on a substrate which cannot be fed to a printing device. The method is distinguished by the fact that the perpendicular spacing Azo of a reference point of the device at a plurality of points which are distributed over the printing web from the surface to be printed is determined in each case at the points which are distributed over the printing web, and the perpendicular spacing Az of the print head from the surface to be printed is set in accordance with a previously recorded measured value. Here, the plurality of points can be distributed uniformly over the length of the printing web. The device for carrying out the method has a measuring device for contactless measurement of the spacing between a reference point of the device and the surface to be printed.
Abstract: A relational expression calculator calculates a relational expression by performing approximation calculation for data strings each of which associates the value of a subject factor, which varies according to a user or an environment, with an input stress measurement value that is measured when a subject device is used. An input stress calculator calculates an input stress, which is input to the subject device, according to the relational expression and to index data on the subject factor. A failure rate calculator calculates a failure rate of the subject device according to the input stress and to a characteristic value distribution of the subject device.
