Abstract
In a method of adjusting record displacement of a serial printer including a recording head which records a plurality of lines at a time in the main scanning direction, a first test pattern which is formed of a plurality of line patterns spaced apart by a prescribed distance is recorded in the main scanning direction, the record sheet is fed by a prescribed amount, and a second test pattern which is formed of prescribed recording patterns is recorded. Based on the positional relations between the first and second test patterns, the feeding amount of the record sheet is adjusted. Since the feeding amount of the record sheet is adjusted based on the positional relations between the first and second test patterns, record displacement in the feeding direction of the record sheet can be adjusted easily, and the cost increase of the serial printer can be suppressed.
