RSPF skew adjustment (Front surface mode)
This adjustment is needed in the following situations:
*
The RSPF section has been disassembled.
*
When replacing the RSPF unit.
*
The RSPF unit generates skewed scanned images.
1)
Create an adjustment chart by printing in duplex mode the self-
print pattern (grid pattern) specified in Simulation 64-2.
SIM 64-2 set values
A = 1,
B = 1,
C = 254,
D = 255
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 RSPF duplex mode, and then check the image for
skews (Set in the RSPF feed tray so that the mark on the
adjustment chart is at the edge).
•
Check with one of the following methods.
[Check Method 1]
[Check Method 2]
Check that the squareness of the main scanning direction
print line for the longitudinal direction of paper is within
1.0mm.
If the above requirement is not met for the paper's front side,
then do step 3).
3)
Remove the hex nut cover in the RSPF diagonal adjustment
screw section.
4)
Raise the RSPF unit upright, and loosen the fixing screw of the
hinge.
