Multiple alignment patterns, each composed of first and second alignment pattern elements printed by forward and backward movements of a print head, respectively, are formed while the relative printing positions of the two elements are shifted. From optical characteristics data thereof, whether the data is influenced by a disturbance is determined. When the data is determined to be less influenced by the disturbance and therefore to be reliable, an adjusting value for aligning positions in printing in reciprocal movements is calculated by use of: data with the smallest relative printing position misalignment between the first and second alignment pattern elements; and data of optical characteristics close to the data. When the data is largely influence by the disturbance, a range of shifting of relative position is widened than that of the data less influenced by the disturbance so that more data pieces are used to obtain the adjusting value.

A check pattern is printed which makes it possible to detect, with high precision, individual patterns corresponding to nozzles of a print head of an inkjet printing apparatus. More specifically, after an alignment mark is printed, ejection of an ink from the nozzles is stopped for a certain time.

When an inkjet printer ejects ink onto a recording medium on a go path and on a return path of a carriage, if ink cannot be ejected onto the same position on the go path and on the return path, image quality becomes poor. Test patterns with shifted ejection timing are hitherto recorded on the recording medium, and appropriate timing is input as a correction value. There is also an inkjet printer which automatically reads a test pattern, but the test pattern is recorded without consideration of a state of a head, and thus, accuracy is low. Therefore, a test pattern having a long period and a test pattern having a short period are recorded, and densities of the test patterns are read by a sensor. An extremum candidate is determined from the test pattern having a long period, and rough adjustment is made first. Then, in a region around the extremum, an extremum is determined from the test pattern having a short period. An extremum corresponding to a period to which the extrema of the two test patterns belong is set as a correction value. By determining ejection timing of the recording head using the correction value, an image in which dot deviation between the go path and the return path is inhibited can be recorded. 1. A recording apparatus , comprising:a recording head for ejecting ink onto a recording medium;conveying means for conveying the recording medium;a carriage for mounting the recording head thereon and reciprocating the recording head for scanning in a direction intersecting a conveying direction of the recording medium;a platen for supporting the recording medium, which is arranged at a position opposed to the reciprocatingly-scanned recording head along a scanning direction of the recording head; anda sensor mounted on the carriage, for detecting a density of an image recorded on the recording medium, record a test pattern on the recording medium in which a position of a dot formed on the recording medium on a go path and a position of a dot formed on ...

A printer includes a scanner to scan the previously printed paper. Software creates a file of areas that need to be blanked out around the areas already printed. A blanking mechanism covers areas that need to be blanked out with white ink or white toner the on previously printed paper. A print mechanism prints a new file over the blanked out paper. 1. A printer comprising:a scanner to scan the previously printed paper and identify print areas;a memory and associated software operatively coupled to the scanner to save identified print areas that need to be blanked out around the areas already printed; anda blanking mechanism operatively coupled to the memory to cover with white ink or white toner the identified print areas that need to be blanked out to output blanked out paper.2. A printer according to claim 1 , further comprising a print mechanism to print a new file over the blanked out paper.3. A printer according to claim 1 , wherein the software identifies a recently printed file and page using the scan result.4. A printer according to claim 1 , wherein the software uses a radius of tolerance around all the printed areas.5. A method of reusing printed paper comprising of(a) scanning previously printed paper to identify previously printed portions;(b) blanking the previously printed paper by printing white toner or white ink over the previously printed portions of the paper to output blanked paper; and(c) printing a new document over the blanked paper.6. A method according to further comprising the step of (d) identifying a recently printed file and page from the scan. 1. Technical FieldThe present inventions relate to printers and, more particularly, relate to a reuse of printed paper for printing.2. Description of the Related ArtThe printers in the market reduce paper usage by printing on both sides of the paper. However, they use a piece of paper only once. The printed paper may then be recycled where significant energy is spent in decomposing the paper back ...

A method and apparatus for self-sensing the detection of print head conditions on high resolution/multiple nozzle piezoelectric ink jet print heads resulting in increased ink jet efficiency and reduced ejection failure with no use of ink. This is done by creating a pressure wave in an ink-fillable ink jet head ejection chamber where the intensity of the induced pressure wave is below a threshold value necessary to produce ejection of a normal sized ink drop through the nozzle. An electrical signal based on the pressure wave is generated and analyzed to determine ink jet head ink drop ejection performance. 1.
