Abstract
The print timing, with which a print hammer impacts a desired type moving on a type carrier, is advanced and then retarded or vice versa during test printing to find an ideal print timing. The amount of advancing and retarding respectively correspond to the negative and positive tolerance limits of the variation in flight time of the print hammer. During test printing the print timing is further advanced and/or retarded so that printed samples are perfect, and then the timing, which has been further advanced or retarded, is used to determine the ideal print timing. Circuit arrangements for performing the method are also disclosed as embodiments of the invention.
