6/02 4-151 DC1632/2240 ADJ 5.1 Repairs and Adjustments Prelaunch Training/Review ADJ 5.1 DADF Side RegistrationPurposeAlign image scanned from document with left side edge of paper. Check1. Make two copies from the Platen Glass to be used as DADF originals. a. Register Test Chart 82E8220 on Platen with side edge metrics SE1 through SE4 against rear registration guide. b. Select the following: ï 1 to 1 sided ï A3 or 11 x 17 Paper Supply ï 100% Reduce/Enlarge ï 2 Copies c. Press Start and write DADF Original 1 on first copy and DADF Original 2 on second copy. 2. Verify side edge registration of DADF Originals. a. On DADF Original 2 measure and record the distance between the side edge and the reference line and write A next to this measurement (Figure 1). b. Check that A is 10.0 ±0.5mm. If A is 10.0 ±0.5 mm, go to step 3. If A is not 10.0 ±0.5 mm, check both of the following and then return to the beginning of this procedure. i. DC129 IOT Lead Edge/Side Edge Registration (ADJ 9.9). ii. IIT Side Edge Registration (ADJ 9.11) Figure 1 Verifying Side Edge Registration of DADF Originals 3. Check DADF Side Edge Registration for Side 1. a. Load both DADF Originals in DADF, 1 on top, with side edge metrics SE1 through SE4 against rear registration guide. Check that side guide touches documents. b. Select the following:ï 1 to 1-sided ï A3 or 11 x 17 Paper Supply ï 100% Reduce/Enlarge ï 2 Copies c. Press Start and discard the first copy. d. On side 1 of copy 2 measure and record the distance between the side edge and the reference line and write B next to this measurement (Figure 2). Figure 2 Checking Side Edge Registration of DADF e. Compare B to A. B must be within ±1.1 mm of A. If the difference between B and A is greater than 1.1 mm, go to step 1 of the adjust- ment. Otherwise go to step 4. 4. Check DADF Side Edge Registration for Side 2. a. Make a 2-sided test pattern. i. Load DADF originals 1 and 2 face up, 1 on top, with side edge metrics toward rear of DADF. ii. Select 1 to 2-sided and press Start to make the 2-sided test pattern b. Make test copies. i. Load 2-sided test pattern with side 1 edge metrics up and toward rear of DADF. ii. Select the following: ï 2 to 1 sided ï A3 or 11 x 17 Paper Supply ï 100% Reduce/Enlarge ï 1 Copy iii. Press the Start button. c. Check that side edge metrics are same distance from edge of paper for both copies. If the difference is greater than ±1.1 mm, go to step 2 of the adjustment. Otherwise DADF Side Registration is good.

6/02 4-152DC1632/2240 ADJ 5.1 Prelaunch Training/Review Repairs and Adjustments Adjustment1. Adjust Side 1 DADF Side Registration. a. Enter NVM Rear/Write (DC131) [715-015]. NOTE: Increasing value moves side edge metrics SE1 through SE4 toward edge. b. If B is more than A, increase the NVM value (15 = approx. 1 mm). If B is less than A, decrease the NVM value (15 = approx. 1 mm). c. Check results of adjustment and adjust if required. 2. Adjust Side 2 DADF Side Registration. a. Enter NVM Rear/Write (DC131) [715-128]. NOTE: Increasing value moves side edge metrics SE1 through SE4 toward edge. b. If copy 2 edge metric is farther away from edge than copy 1, increase the NVM value (15 = approx. 1 mm). If copy 2 edge metric is closer to edge than copy 1, decrease the NVM value (15 = approx. 1 mm). c. Check results of adjustment and adjust as required. NOTE: 2 to 2-sided or 2 to 1-sided must be selected to view a change in [715-128]. [715-128] produces no change in 1 to 2-sided copying. NOTE: Total lead edge deviation for DADF is ±1.6 mm. Total lead edge deviation for IIt is ±0.5 mm. This leaves ±1.1 mm for DADF when a copy paper test pattern is made for use in DADF.

Check DADF opening and closing action. a. Raise DADF and check that it remains in fully raised position. b. Check that the DADF closes from a height of 100 ±50mm by its own weight without excessive noise (Figure 1). Figure 1 Checking DADF Height Adjustment WARNINGTo avoid personal injury or shock, do not perform repair or adjustment activities with the power switch on or electrical power applied to the machine. CAUTION When removing the Rear Cover, disconnect LED Connector on DADF PWB. 1. Remove the Rear Cover. (REP 5.18) 2. Adjust the Left Counterbalance (Figure 2). NOTE: Rotate in A direction for stronger spring pressure Rotate in B direction for weaker spring pressure a. Loosen the nut. b. Rotate the Set Screw for the adjustment. c. Tighten the nut.

Remove Front Cover. (PL 20.1) 2. Remove Entrance Tray. (PL 20.1) 3. Remove the Document Transport. (REP 5.17 ) 4. Check DADF Parallelism. a. Manually hold down the DADF. b. Check that the distance between the DADF Rear Frame and the Rear Registration Edge is 20 ±1 mm (Figure 1). c. Perform the same check at the left end of the DADF. If 20 ±1 mm is not measured in each check, or the measurements are different, go to the adjustment. Otherwise DADF Parallelism is good. Figure 1 Checking DADF Parallelism Adjustment CAUTION The DADF Parallelism must be made within ±1mm of the specified range. CAUTION When removing the Rear Cover, disconnect LED Connector on DADF PWB. 1. Remove Rear Cover (REP 5.18). 2. Adjust DADF Parallelism (Figure 2). Figure 2 Adjusting DADF Parallelism 3.

Remove Front Cover (PL 20.1). 2. Entrance Tray (PL 20.1). 3. Check Document Transport Height (Figure 1). a. At left end of Document Transport, check that there is 24.5 ±0.3 mm between top of Document Transport Frame and Top of Rear Registration Edge. b. At Right end of Document Transport, check that there is 24.5 ±0.3 mm between top of Document Transport Frame and Top of Rear Registration Edge. c. If there is more or less than specified, perform the adjustment on the counterbalance for the side that is not in specification. Adjust both counterbalances if required. Otherwise, Document Transport Height is good. Figure 1 Checking Document Transport Height Adjustment CAUTION When removing the Rear Cover, disconnect LED Connector on DADF PWB. 1.
