AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 13
3) Gently pulling out each check sheet for SPF levelness adjustment,
make sure that no gap is felt between the CIS guide boss and the
glass for SPF mode for each of the front and rear frame sides.
If the above requirement is not met, do step 4.
4) Turn the height adjusting screw on the left side of the SPF rear
frame to adjust the fore/aft levelness between the SPF frames.
If the front frame side is higher (i.e. there is a gap in B) : turn the height
adjusting screw L on the left side of the SPF rear frame in the clock-
wise direction.
If the rear frame side is higher (i.e. there is a gap in A) : turn the height
adjusting screw L on the left side of the SPF rear frame in the counter-
clockwise direction.
Repeat steps 2 to 4 until an acceptable result is obtained.
This adjustment is needed in the following situations:
• The SPF section has been disassembled.
• The SPF unit has been replaced.
• The SPF unit generates skewed scanned images.
1) Create an adjustment chart by printing in duplex mode the self-
print pattern (grid pattern) specified in Simulation 64-1.
Make sure that the print grid pattern is almost in parallel with the
paper edges, and apply position marks 'A', 'B', 'C' and 'D' to the
leading and trailing edges of the paper for both front and back
sides of the paper.
2) Copy the adjustment chart (created in step 1) to A3 (11" x 17")
paper in duplex mode, and then check the image for skews (Set in
the SPF feed tray so that the mark on the adjustment chart is at the
edge).
Check with one of the following methods.
[Check Method 1]
(Front side)
Make sure that the output satisfies the condition: |a-b|
≤
± 1 mm
[Check Method 2]
If the above requirement is met for the copied image of the paper's
front side but not for the paper's back side, skip to step 4.
If the above requirement is not met for the paper's front side, then
do step 3.
3) Loosen the hinge screws and lower the two attachments.
Note: If the above procedure will not allow an adjustment, turn the
adjustment screw R on the rear frame of the SPF to perform an
adjustment.
