ADJ 9.1.0 Toner Density Adjustment

Purpose
To set a suitable toner density for printing by determining the toner density in the Developer
Unit from the difference between the Read value of the TC Sensor and the reference value,
and by adjusting the toner level accordingly.
Adjustment
1. Place the Standard Test Pattern (82E13120) on the platen glass.
2. Enter UI Diagnostic Mode.
3. Enter Max Setup and select Adjust Toner Density.
NOTE: The difference between TC Target and TC Measured should be within +/- 30.
NOTE: If TC Measured is to high, the amount of toner used to create the patch is too low.
Therefore use a positive number in the Select Quantity to increase the amount of toner in the
developer.
NOTE: If TC Measure is to low, the amount of toner used to create the patch is too high. There-
fore use a negative number in the Select Quantity to decrease the amount of toner in the
developer.
NOTE: When the negative numbers are used in Select Quantity, the routine will print solid area
coverage on several sheets of paper in order to tone down the developer.
4. Select Quantity, using the Up and Down buttons displayed for Magenta, Yellow, Cyan and
Black. Adjust in 2 to 3 increments.
5. Press Start button to begin Toner Density Adjustment.
6. After the adjustment ends, the TC Measured value will be displayed.
7. Repeat steps 4 thorough 6 until all TC Measurements is within +/-30 of the TC Target
8. Exit Diagnostic Mode.
9. Place the Standard Test Pattern (82E13120) on the platen glass.
10. Make 5 copies of the test pattern and determine if Toner Density is properly adjusted.
11. Repeat this procedure until the Toner Density is satisfactory.

ADJ 9.1.1 IOT Image Registration

Purpose
The purpose of this adjustment is to properly align the ROS image to the paper / media, for all
trays, all modes, print and copy. This adjustment must be completed prior to the IIT Lead Edge/
Side Edge Registration, and the DADF Lead Edge Registration.
Specification
• For A3 paper, the specifications are as follows:
– The specification for lead edge registration is 10.0 +/- 0.5 mm.
– The specification for side edge registration is 8.0 +/- 0.5 mm. (Both Sides)
• For 11x17" paper, the specifications are as follows:
– The specification for lead edge registration is 10.0 +/- 0.5 mm.
The specification for side edge registration is 10.0 +/- 0.5 mm. (Both Sides)
Introduction
Initial set up should be done by following these 5 sequenced steps:
1. Tray Baseline
NOTE: The Tray Base line should only be performed as required to bring the machine
back to the factory settings.
2. Tray 1 Lead Edge Set Up
3. Side Edge Adjustment, Trays 1, 2, 3, and MSI
4. IIT Alignment, Platen Glass
5. DADF Lead Edge / Side Edge Registration
NOTE: Copies / Prints are delivered to output Trays in different orientations depending on the
job; example, Platen Glass, DADF, Finisher Un-collated or Collated/Stapled. Read and under-
stand proper image viewing in each adjustment section.
NOTE: Label each image as it is removed from the output tray.
Mark the following references on each print:
• Tray 1, 2, 3 or MSI
• Color or B/W
• Mode, Bond, HW1 or HW2
• Lead Edge
NOTE: Lead Edge to Trail Edge Registration. Decrease the NVM Value to move the image
towards the Lead Edge. ( 9 bits = 1 mm)
NOTE: Diagnostics must be exited for any Side Edge NVM changes to take effect. Lead Edge
NVM changes take effect immediately.
NOTE: Positive numbers (bits) increases the image distance from the paper edge and nega-
tive numbers (bits) decreases the distance from the paper edge.
Tray Baseline
1. For 2TM machines Load all paper trays with 11X17"/A3 paper SEF.
For TTM machines load paper Tray 1 and MSI tray with 11x17"/A5 paper SEF and Tray 2
and Tray 3 with 8.5x11" paper LEF.
