摘要： An image-forming apparatus includes a developing roller and a developing blade. The developing blade applies toner to the developing roller to form a thin layer of toner on the developing roller. The image-forming apparatus performs a printing operation that includes a paper-feeding period and a developing period following the paper-feeding period. The developing roller rotates relative to the developing blade at a first speed during the paper-feeding period and then at a lower second speed than during the developing period, thereby eliminating chance of white lines of occurring in a printed image. The developing roller may be rotated at a constant speed in each printing operation until the circumferential surface of the developing roller has traveled over a certain cumulative distance. When the surface has traveled over the first distance, the developing roller may be rotated at an increased speed over a certain distance.

摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： An ink jet recording apparatus is provided with a black head and a plurality of color heads. The black head has a predetermined number of first orifices aligned at predetermined intervals (e.g. 0.0169 mm) in a sub scanning direction (direction in which a print medium travels). The plurality of color heads eject different colored ink drops. Each color head has the predetermined number of second orifices aligned in the sub scanning direction perpendicular to the main scanning direction. The second orifices of adjacent color heads are aligned in a main scanning direction perpendicular to the sub scanning direction.

摘要： An ink jet head has a plurality of ink pressure chambers defined therein and a surface to which a plurality of ink pressure chambers open. An orifice plate having an orifice therein is bonded to the surface. When manufacturing the ink jet head, a coating of an insulating material is first formed on an inner wall of the ink pressure chambers and subsequently a re-dissolvable curingresin is applied to the ink jet head in an area from the inner walls to the surface. Then, the coating and the resin deposited on the surface are removed from the surface. Then, the resin deposited on the coating in the ink pressure chambers is dissolved to remove the resin from the inner wall. Finally, the orifice plate is bonded to the surface.

摘要： An ink jet recording apparatus includes a printhead that ejects black ink drops and colored ink drops through a plurality of corresponding ink nozzles in accordance with print data. The printhead ejects ink drops when the printhead is moved to scan a recording medium in a forward direction and a reverse direction opposite to the forward direction. The forward and reverse directions are perpendicular to a direction in which the recording medium travels. A print data identifier separates the print data for a line into black print data and color print data. A print data selector supplies one of the black print data and color print data to the printhead when the printhead scans the recording medium in the forward direction, and the other of the black print data and color print data to the printhead when the printhead scans the recording medium in the reverse direction.

摘要： An ink jet recording apparatus is of the construction where information is printed by ejecting ink drops through orifices of an ink jet head mounted on a carriage. The ink jet recording apparatus includes a cap for closing the surface of the ink jet head in which the orifices are formed. The cap is adapted to move between a first position at which the cap is fully disengaged with the orifices, and a second position at which the cap is engaged with the orifices. The cap communicates with a suction mechanism which negatively pressurizes the cap when the cap is at the second position. The carriage, cap, and suction mechanism are controllably driven by a controller. The cap is provided with an engagement member, which may take the form of a sweep blade, attached to its tip for sweeping the surface in which the orifices are formed. The controller causes the carriage to move when the engagement member moves to the second position so that the engagement member sweeps the surface to remove denatured ink and foreign matters from the orifices into the cap.

摘要： A developing unit is disposed substantially directly under a toner chamber and receives toner through an opening formed in the toner chamber, and includes a developing roller, a supplying roller, and a developing blade. The developing roller supplies toner to an electrostatic latent image formed on an image bearing body. The supplying roller rotates in contact with the developing roller to supply the toner to the developing roller. The developing blade is in pressure contact with the developing roller to form a thin layer of toner on the developing roller. The developing blade is in contact with the developing roller at a first position spaced at least 5.84 mm from a second position at which the supplying roller is in contact with the developing roller. An agitating member may be added over the developing roller and supplying roller and between the first position and the second position.

摘要： A dot data generator receives print data from a host apparatus and generates dot data from the print data. Dots have different diameters according to a gradation level. A drive frequency setting section sets a drive frequency in accordance with the print data. A drive signal generator generates a timing in timed relation with the drive frequency. A recording head is driven at the generated timing to form a plurality of dots on a print medium. An operation circuit determines a total drive time forming dots for each line in the main scanning direction. The drive frequency is set on a line-by-line basis in accordance with the total drive time. The timing may be delayed so that dots are formed always at accurate print positions irrespective of the scanning speed in the main scanning direction and in the sub scanning direction.
