SP6-05: Scanning speed - platen
SP6-06: Scanning speed - ADF
1. Make copies of the test pattern printed during the previous adjustments (
☛
previous page), in platen mode at 90 rpm (speed 3). Use the 10th print for the
adjustment.
2. The length of the 6 squares in the feed direction should be 130 mm.
3. If it is not, calculate the reproduction ratio using the following formula.
{(130 - Value) / 130} x 100 =
±±±±
X.X % (Round off to one decimal place)
Example: If the value is 133, {(130 - 133) / 130} x 100 = - 2.3 %
4. Access SP6-05, input the calculated ratio, and press the Enter key.
5. Check again to make sure that the ratio is correct.
6. Make copies of the test pattern in ADF mode and repeat the process using
SP6-06.
SP6-03: Scanning start position - platen
SP6-04: Scanning start position - ADF
1. Make copies of the test pattern printed during the previous adjustments (
☛
previous page), in platen mode at 90 rpm (speed 3). Use the 10th print for the
adjustment.
2. The space between the leading edge and the next line should be 11 mm.
3. If it is not, access SP6-03, input the gap value and press the Enter key.
Example: If the value is 16 mm, 16 - 11 = +5.0
4. Repeat the procedure to make sure that the gap is correct.
5. Make copies of the test pattern in ADF mode and repeat the process using
SP6-04.
SP6-01: Main scan position - platen
SP6-02: Main scan position - ADF
1. Make a copy in platen mode at 90 rpm (speed 3).
2. Measure the difference between the center of the main-scan on the original and
on the print.
3. Access SP6-01, input the gap value and press the Enter key. (If you input a
positive value, the image moves towards the operation side.)
4. Repeat the procedure to make sure that there is no difference.
5. Make a copy in ADF mode and repeat the process using SP6-02.
