Initial Issue
ADJ 18.1.1 IOT Lead Edge/Side Edge Registration
Purpose
To align the image on the drum with the proper position (Lead/Side Edge) of the paper.
Check
1. Load A4 paper into the Tray in SEF orientation.
NOTE: The Tray Select will follow the setting value of NVM [623-021]
(DIAG_TEST_PRINT_INPUT_TRAY).
2. Enter the CE Mode and input 999-980 (Maintenance Report) in the Chain-Link.
3. Pressing the [Start] button prints the Maintenance Report.
4. Measure the Lead and Side Edges of the print pattern.
• Lead Edge: Part A of the pattern
• Side Edge: Part B of the pattern
Figure 1 j0lj41895
5. Check that the measured values of the Lead Edge (A) and Side Edge (B) fall within the
corresponding specifications.
NOTE: To perform measurement for the Lead Edge (A) and Side Edge (B) of Duplex
printouts, load the Maintenance Report that was output on the Platen, and make a 1 -> 2
Sided copy to perform the measurement.
Adjustment
1. Enter the CE Mode.
2. Adjust the NVM until each measured value of the Lead Edge (A) and Side Edge (B) fall
within the specifications of the corresponding mode.
• If the measured value is short: Set a larger value.
• If the measured value is long: Set a smaller value.
3. After adjustment, print the Maintenance Report in the same mode again.
4. Repeat the procedure until the measured values of the Lead Edge (A) and Side Edge (B)
fall within the specifications.
