Embodiment Construction

[0050] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0051] figure 1 shows an embodiment of the present invention. like figure 2 As shown in , the recording head includes two linear columns, each column consisting of a plurality of dot-forming elements linearly arranged at a fixed pitch. These linear columns are arranged side by side in the width direction of a recording medium such as a recording sheet, and these dot forming elements are arranged in a staggered manner. In this embodiment, the spot forming element is an impact wire. The recording head 1 is installed on the slide 4, and the slide is coupled with the drive motor 2 of the slide through a synchronous timing belt 3 in power. The recording head 1 reciprocates along the axial direction of the reel 5 driven by the sliding seat 4 . The roll 5 is coupled to the paper feed motor 6 via a gear train 7 , and the amount of recording paper supplied fr...

Abstract

A serial recording apparatus is disclosed which is capable of continuously printing even if a dot-forming element (or elements) of the element array of the recording head is defective, by substituting for the defective dot-forming element, a substitution dot-forming element. The serial recording apparatus also automatically detects a defective dot-forming element of the element array of the recording head. In operation, print data of the defective dot-forming element, which loses its dot-forming function, is saved in a second print-data storing device, and a first printing pass is carried out. In the second printing pass, a normal dot-forming element is moved to a location on a recording sheet which would otherwise be subjected to printing by the defective dot-forming element, and reads out the print data from the second print-data storing device to print it on that location.

Description

technical field [0001] The present invention relates to a serial recording apparatus in which a recording head has a plurality of dot forming elements arranged in the paper feeding direction, the recording head is driven by a slide to reciprocate along the recording paper, thereby printing on the recording paper point out. Background technique [0002] In a serial recording device (the device is called a recording device in the sense that the device records characters, graphics, etc. on a recording medium such as paper), a recording head has a plurality of dot forming elements linearly arranged direction. These dot forming elements may be impact dot filaments, ink nozzles, heat generating elements or the like. The dot forming elements thus arranged are selectively driven according to image data representing images of characters, graphics, etc., and print dot images on the recording paper as reproductions of original images. Occasionally, one or more such dot-forming eleme...
