摘要： A control method is provided for an ink jet recording apparatus 30 including a recording head 32 for ejecting ink to a medium 31, a heating means 46 for heating the recording head 32, an ink storage part 12 which reserves ink supplied to the recording head 32, and a negative pressure adjusting part 40 which adjusts a pressure in an inside of the ink storage part 12 to be a negative pressure. In the control method, when the ink jet recording apparatus 30 is to be turned off, heating of the recording head 32 by the heating part 46 is turned off but the negative pressure adjusting part 40 is left to be in an “ON” state so that the negative pressure in the inside of the ink storage part 12 is maintained and, after that, the negative pressure adjusting part 40 is turned off.

摘要： A mechanism for switching a paper holding roller of an automatically feeding printer between a contact position for holding a paper against the platen and a separation position away from the platen utilizing the platen power source. A transmission mechanism includes a trigger which is moved selectively by an electro-magnetic member to engage a gear between the platen power source and a roller lever on which the paper holding roller is mounted to move the paper holding roller between the contact/separation positions. In one embodiment, two partial gears engage a gear portion of the lever to move the lever in both directions. In another embodiment, an epicyclic lever is selectively rotated in one of two directions to engage one of two oppositely rotating epicyclic gears to move the paper holding roller.

摘要： A sheet end detector comprising a light-emitting element and a light-receiving element for detecting changes in the amount of light associated with movement of a piece of a recording medium is provided. A standard value calculator detects the difference between the sheet end detector platen voltage Vp corresponding to light reflected only from said platen and said sheet end detector paper saturation voltage Vm corresponding to light reflected only from the recording medium. The amount necessary to feed the paper for platen voltage Vp to reach paper saturation voltage Vm is a constant value, irrespective of recording medium characteristics, which is when all of the light is reflected by the recording medium and the entire end portion of a piece of a recording medium has reached a predetermined position relative to the position of the sheet end detector. A standard value is calculated by multiplying this difference by a constant coefficient C and then adding back the lesser of Vp or Vm, C being a numerical value greater than 0 and less than 1 and being an indication of the desired position of the leading edge of the recording medium. A comparator compares the standard value and a signal from the sheet end detector and determines when the signal corresponds to the standard value, which is indicative that the presence of a leading edge or trailing edge of the recording medium has reached a predetermined position.

摘要： A printing apparatus arranged to perform printing while a monochrome printing head and a color printing head are moved in a direction in which the two heads are moved, the printing apparatus being arranged to print a plurality of patterns in which the relative quantity of deviation of printing timings of the two heads is changed in a stepped manner to cause a user to select a pattern having the smallest quantity of deviation among the plural patterns. Then, the selected pattern is used as a central value when a plurality of patterns in which the relative quantity of deviation of the printing timings of the two heads is changed in a stepped manner are furthermore printed to cause the user to select a pattern having a smallest quantity of deviation from the plural patterns. The above-mentioned process is repeated as necessary. As a result, the operation which is performed by the user to adjust the printing position can simply and easily be performed. Control is performed in such a manner as to change color to be printed by the color printing head whenever an adjustment mode in which the relative quantity of deviation of the printing timing is adjusted is started.

摘要： A ribbon mask for use with a impact dot matrix printer is provided. The ribbon mask comprises a head confronting surface and a pair of opposed side plates each positioned on an opposite side of the head confronting surface. An obtuse angle is formed between said head confronting surface each of the opposed side plates. A pair of fitting tabs are also provided. Each fitting tab is positioned on one of the pair of opposed side plates. An acute angle is formed between each of the fitting tabs and a plane parallel to a plane in which the head confronting surface lies. As a result of this construction, when the ribbon mask comes in contact with a sheet of a recording medium, the ribbon mask is deformed so that a portion of the head confronting surface comes into contact with an end of a recording head, which in turn prevents the ribbon mask from interfering with the sheet of the recording medium.
