SP Adjustments
SP
On each grid pattern measure the width from block 1 to block 150 (150
blocks) then average the three measurements. The width must be 812.8
2916-1
mm. If the average measured width is not 812.8 mm, adjust this SP until
the width is 812.8 mm.
On each grid pattern measure the length from block 21 to block 204 (184
blocks) then average the three measurements. The length must be 997
2916-2
mm. If the measured length is not 997 mm, adjust this SP until the length
is 997 mm.
Step 2: Scanning Magnification
1.
Make a 1:1 copy of the A0 SEF Magnification Chart with plain roll paper.
!
You can use a different test chart, if it has lines 1000 mm long in the sub-scan
direction and 700 mm long in the main-scan direction.
2.
Measure the length and width of the images on the original and the copy.
3.
Do these SPs in the sequence shown in this table, if the measurements are not in the
standard range:
SP
4008
Less than ±0.5
4101
Less than ±0.5
Step 3: Magnification for Paper Type: Translucent
1.
Make a 1:1 copy of the A0 SEF Magnification Chart with translucent (tracing) paper.
!
You can use a different test chart, if it has lines 1000 mm long in the sub-scan
direction and 700 mm long in the main-scan direction.
2.
Measure the length and width of the images on the original and the copy.
3.
Do the same measurements that you did for "Step 1: Magnification for Paper Type:
Plain."
4.
Do these SPs in the sequence shown in this table, if the measurements are not in the
B286/B289
Standard
Scanner Sub Scan Magnification
Scanner Main Scan Magnification
