<Registration Adjustment: Side-to-Side (Main scan) / Leading edge (Sub scan)>
1. Output a test pattern and check [A] shown above. The value of SP1-001 (Leading Edge
Registration) needs to be adjusted within the standard range if the value of [A] does not reach
[5.2±2mm] for Plain Paper or [4.2±1.5mm] for thick paper, including Medium Thick.
2. Output a test pattern and check [B] shown above. If the value of [B] does not meet [2±1mm], the
value of SP1-002 (Side-to-Side Registration) needs to be adjusted within the standard range.
• If the registration adjustment could not be set within the standard, adjust the right and the leading
edge erase margins. (See the information below)
<Erase margin adjustment>
1. Output a test pattern and check [A] and [B]. If the value of [A] and/or [B] are out of the standard
range, adjust them with SP2-103 (Erase Margin Adjustment).
• Adjust the erase margin for [C] and [D] only when the registration cannot be adjusted within the
standard range. After completing the adjustment, perform registration adjustment, then adjust the
erase margin for [A] and [B] (see "Main scan magnification adjustment" below).
<Main scan magnification adjustment>
1. Output [7: Grid Pattern Small] with SP2-109-003 (Test Pattern).
2. Check whether the magnification meets the standard. If it is out of the range, change the standard
value (Bk) of main scan magnification through SP2-102-001/002/003.
• You do not need to adjust other three colors (Ma/Cy/Ye) because they will be automatically
adjusted in the next steps (Scanner-related adjustment).
• These SPs enable you to adjust for three line speeds (Standard, Middle, Low speed) for
plain/thick paper modes. However, you must input the same value regardless of line speed.
