ADJ 1.3.1, ADJ 1.3.2
Repairs and Adjustments Initial Issue
ADJ 1.3.1 IIT Lead Edge Registration
Purpose
To adjust the IIT scan timing in the Slow Scan direction and to correct the copy position.
CAUTION
Avoid using this procedure when performing the adjustment of the Lead Edge Registration.
This procedure should be performed only when the actual IIT Regi is not appropriate. This is
because the IIT Lead Edge Registration affects the precision of the document size detection,
etc.
NOTE: Before performing this procedure, make sure that the IOT Lead Edge Registration is
appropriate. (Refer to
ADJ 18.1.1 IOT Side/Lead Edge Registration.)
Check
1. Place the Test Chart (499T283) on the Platen Glass correctly and make a copy in the fol-
lowing copy mode:
• Copy Mode: 'Black'
• Paper Size: 'A3'
• Reduce / Enlarge: '100%'
• No. of Copies: '2'
2. Check that the distance between the lead edge of the 2nd copy and the reference line is
10.0 +/-1.6 mm or the same as the dimension on the Test Chart. (Figure 1)
Figure 1 j0mf40954
3. If the value is not within the specified range, adjust it as follows:
Adjustment
1. Enter NVM [715-050] Platen SS Registration Adjustment.
2. Change the value.
• Change amount for 1 step: 2 pulse
• Increment of the value: The image moves towards the Tail Edge.
• Decrement of the value: The image moves towards the Lead Edge.
ADJ 1.3.2 IIT Side Registration
Purpose
To adjust the IIT scan timing in the Fast Scan direction and to correct the copy position.
CAUTION
Avoid using this procedure when performing the adjustment of the Side Registration. This pro-
cedure should be performed only when the actual IIT Regi is not appropriate. This is because
the IIT Side Registration affects the precision of the document size detection, etc.
NOTE: Before performing this procedure, make sure that the IOT Lead Edge Registration is
appropriate. (Refer to
ADJ 18.1.1 IOT Side/Lead Edge Registration.)
Check
1. Load A3 paper into Tray 1.
2. Place the Test Chart (499T283) on the Platen Glass correctly and make a copy in the fol-
lowing copy mode:
• Copy Mode: 'Black'
• Paper Tray: Tray 1
• Reduce / Enlarge: '100%'
• No. of Copies: '2'
3. Check that the distance between the side edge of the 2nd copy and the specified value is
10.0 +/-2.1 mm or the same as the dimension on the Test Chart. (Figure 1)
Figure 1 j0mf40955
4. If the value is not within the specified range, adjust it as follows:
Adjustment
1. Enter NVM [715-053] Platen FS Registration Adjustment.
2. Change the value.
• Change amount for 1 step: 1 dot
• Increment of the value: The image moves towards the IN side.
• Decrement of the value: The image moves towards the OUT side.
