Chapter 44-21A single press on each switch will shift the original stop position by 0.5mm.When the correct position is attained (after switch operation), press thepush switch SW2.- The original will be delivered, and the new setting will be stored inmemory.F-4-105T-4-8F-4-106Holding down the push switch will not cause more than a single shift.EXIf the copy paper stops 12 mm from the copyboard glass,Close the DADF slowly leaving the copy paper on the copyboard glass.To shift the stop position 1 mm to the left, the following is true:1 0.5 (adjustment interval) = 2Hence, press the push switch SW4 twice, and press the push switch SW2.- The copy paper will be delivered, and new setting will be stored in memory.4.3.1.7 Stream Reading Speed Adjustment 0013-37081) Place the test chart in the original pickup tray, and make a copy at a 100%reproduction ratio.2) Put the copy and chart together, and compare the length of the imagein feed direction, making sure that dimension a is as indicated. If not, goto the next step.standard: a F-4-1073) Make the following selections: FEEDER>ADJUST>LA-SPEED; then,change the setting to make adjustments.-To make the image on the copy longer, decrease the setting (so that thestream reading speed will be decreased).-To make the image on the copy shorter, increase the setting (so that thestream reading speed will be increased).[ range -30 to 30 : -3 to + 3 % ]4.3.2 Adjustment at Time of Parts Replacement4.3.2.1 Outline 0011-3496T-4-94.3.2.2 Replacing the EEPROM 0011-3499Perform the following when replacing the ADF controller PCB.1) Remove the EEPROM (IC8) from the faulty ADF controller PCB.Switch Direction of shiftSW3 RightSW4 LeftJ1J2J5J3 J6 J7 J8 J9 J10J16 J15J11J14IC8J13J12J4 CB1SW1DSP1SW4SW3SW2OriginalSW3SW4Major parts Work- ADF controller PCB 1) Replacement of theEEPROM-EEPROM (memory back-up) 2) Adjust the sensors and thedelivery motor-Reversal sensor (S1)-Pre-registration roller paper sensor (S2)-Post-registration roller paper sensor (S3)-Separation paper sensor (S4)-Skew paper sensor (S5)-Original sensor (S6)-Original trailing edge sensor (S7)-Manual feed registration roller paper sensor (S9)-Delivery motor (M5)aa
