<Scanner magnification adjustment>
1. Set the test chart on the exposure glass, select a feed tray and start copying. You can select any
feed tray.
2. Check whether the output image was within the standard range compared with the test pattern. If
the image is out of range, execute SP4-008(Sub scan Magnification Adj.) to change the
magnification. A lower value provides images that are stretched in the feeding direction. On the
other hand, a greater value provides a reduced image.
• Standard (Magnification tolerance)
* Same Size: Main scan: Less than ±0.55%
* Same Size: Sub scan: Less than ±1.00%
* Reduction: Main/Sub scan: Less than ±1.00/reduction ratio
* Enlargement: Main/Sub scan: Less than ±1.00%
<White reference correction>
Turn the main power Off and On. The white and black reference will be corrected automatically with this
procedure.
<Squareness (Skew) adjustment>
• Do this procedure after adjusting the image area with SP2-109: pattern 14 - trimming area.
• Method for checking
1. Set the test chart on the exposure glass, select a feed tray and start copying.
2. Count the number of horizontal bars in the two corners of the copy image area. There should
be the same number.
