In an ink jet head using a thermal energy for ejecting ink, this invention aims to reliably and uniformly remove kogations deposited on a heat application portion in contact with the ink. To realize this objective, the upper protective layer is arranged in an area including the heat application portion so that it can be electrically connected to serve as an electrode which causes an electrochemical reaction with the ink. The upper protective layer is formed of a material containing a metal which is dissolved by the electrochemical reaction and which does not form, on heating, an oxide film which hinders the dissolution. With this arrangement, a reliable electrochemical reaction can be produced to dissolve a surface layer of the upper protective layer, thereby removing kogations on the heat application portion reliably and uniformly.

A density variation correction method for a printing system includes printheads in at least one linehead printing a test block pattern on a print media. A density variation trace is produced for each printed test block in the test block patterns by capturing an image of each test block and averaging pixel data in a transport direction. The density variation traces associated with a known print density represented in the test block pattern are compared with a respective reference density value. A determination is made as to whether there is a difference between each density variation trace and the respective reference density value. If there is a difference, the density variation trace is adjusted to match the reference density value. The method can be repeated for all of the known print densities represented in the test block pattern and for all of the lineheads in the printing system.

An indirect media flatness measurement system, and method, by which the appropriate level of hold-down force may be determined with some degree of quantitative accuracy. In an ink jet printer that is operative to subject a substrate media to a hold down force during printing, the method including printing a predetermined test image having a predetermined pattern on a substrate media using an ink jet print apparatus to produce a test print. Optionally, pattern may be an array of test symbols. The test symbol may comprise a line printed on the substrate media in a direction perpendicular to a process direction of the printer. The test print is compared with the predetermined test image, including measuring drop placement errors of test symbols. The height of the substrate media at the location of each test symbol is calculated based upon the drop placement error.
