Chapter 22-323. controls the speed at which paper is moved to suit the temperature inside the machine2.4.2 Other Control2.4.2.1 Skew Correction Function 0008-1720This function is utilized to correct the skew of the paper to be fed, using the registration shutter method.The operations of this function are discussed below.When paper is fed to the registration roller, the leading edge of paper is pushed against the registration shutter to correct a skew (1). Paper is warped as the feedroller keeps pushing it when it is pushed against the shutter (2). The shutter is lifted up by the stiffness of paper as paper warps, and paper passes through the shutter(3). It allows the skew of paper to be corrected.F-2-472.4.2.2 Feed Speed Control 0008-1721In this control, a feed speed is changed based on the types of the fed paper in order to prevent fixing defects.The DCNT Board changes a feed speed in two levels based on a paper type specification command sent from the SCNT Borad.Types of paper and their feed speeds are indicated below.T-2-62.4.2.3 Detecting the Machine Inside Temperature 0008-1723As a means to prevent overheating inside the machine, the machine is equipped with a thermistor (TH3) used to detect the temperature inside the machine (foundnear the toner cartridge motor).If the STNT board finds that the machine inside temperature has exceeded an upper limit (Td) at time of continuous printing/copying, it will increase the distancebetween sheets to prevent overheating. If the temperature falls below a specific level (Tu), on the other hand, it changes the sheet-to-sheet distance to normal.Media type Print type Feed speedPlain paper Full-color Normal speedMono-colorHeavy paper Full-colorMono-colorOHP sheet ------------Mono-colorThick paper Full-colorMono-colorSpecial paper Full-color Half speedMono-colorEnvelope Full-colorMono-colorLabel Full-colorMono-colorRegistration shutterPaperRegistration shutterPaper[1][2][3]Registration roller
