Initial issue
ADJ 5.1 DADF Side Registration
Purpose
Align image scanned from document with left side edge of paper.
Check
1. 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:
• 1 to 1 sided
• A3 or 11 x 17 Paper Supply
• 100% Reduce/Enlarge
• 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:
• 1 to 1-sided
• A3 or 11 x 17 Paper Supply
• 100% Reduce/Enlarge
• 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).

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:
• 2 to 1 sided
• A3 or 11 x 17 Paper Supply
• 100% Reduce/Enlarge
• 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.
