Maintenance Menu5.15.1.7 ADF scanning position adjustment (rear-end registration)Adjust the rear-end scanning position (vertical scanning direction).Reference value Default value Adjustable range Unit of adjustmentFront ± 1.8 (mm) -43 (2.6617mm) -127 +127 *1(–7.86 7.86mm) 0.0619mm / stepBack ± 2.3 (mm) -43 (2.6617mm) -127 +127 *1(–7.86 7.86mm) 0.0619mm / step* 1 Adjustment in increment of 1 item (0.0619 mm) is possible in thissetting. However, adjustment should be performed in incrementof 16 items (1 mm) as a guide line due to document running at anangle.Measurement1) Set the A3 document on ADF.2) Scan both sides of the test chart with ADF at 300 dpi. (Such as Scan To USBMemory)3) Measure length of the “A” portion as shown in the drawing. If it does not satisfy thereference value, perform adjustment as described below.4) If length of “A” portion stays within the reference value, it is the end of measurement.Adjustment1) Set the ADF rear-end registration.• If the measurement data is short: (When the rear-end is missing.)=> Adjust the setting value in the positive (+) direction.• f the measurement data is long (If shade is present in the rear-end of document)=> Adjust the setting value in the negative (-) direction.Note! The rear end position adjustment should be executed after the top endposition adjustment is completed. In addition, scanning is stopped beforethe rear end is reached if amount of the scanning lines specified by the CUside are scanned in the copy mode and scan mode even though the rear-end position adjustment is increased in the positive (+) direction. Therefore,adjustment must be performed in the manner of increasing the settingvalue gradually after checking the registration in the negative direction.(If an excessively large value is set, it can adversely affect the fax scanningat the rear-end.)Test Chart No.99-2A99-2(B)2000.1
