6-4 Phaser 7400 Color Printer Service Manual

Automatic Thickness (ATS) Calibration

The thickness of media being printed on can affect print-quality. The Phaser 7400

measures the thickness of print media and adjusts the Fuser temperature and print

speed accordingly. Perform ATS calibration if the NVRAM, Media Thickness Sensor,

or Registration Assembly are changed.

arn

In order to properly calibrate the Media Thickness Sensor, you MUST use

Phaser 35-Series Premium Transparencies. Using any other transparency can

cause significant damage to the Fuser and fail the adjustment.

ATS 4-Sheet Calibration

1. Enter Service Diagnostics.

2. Scroll to Adjustments/Calibrations, and press OK.

3. Select ATS 4-Sheet Calibration, and press OK.

4. Select Edit Thickness Data, and press OK.

5. Select Microns, and press OK.

6. The printer enters the Edit Thickness Data menu.

7. Change the thickness value to 140, using the Up Arrow / Down Arrow buttons

to change the first number to 1. Press the Help (?) key to move the cursor to the

second digit, then the third digit. Once the value is set to 140, press OK.

Note

The value set in Step g, 140 microns, is the average thickness of Phaser 35-Series

Premium Transparencies. Using another type of transparency produces

inaccurate results.

8. On the Control Panel, select Execute Thickness Calibration, and then press the

OK button.

9. When prompted open Tray 1 (MPT) and load 5 sheets of Phaser 35-Series

Premium Transparency.

10. The printer indicates that it is ready to run the calibration and picks 3 consecutive

sheets of media from Tray 1 (MPT), using them to calculate a reference

thickness.

11. After the reference is set, the printer picks and measures the fourth sheet to test

the calibration. If the fourth sheet falls within the expected thickness range, the

printer displays Thickness Calibration Passed.

12. If the fourth sheet does not measure as expected, the calibration displays

Thickness Calibration Failed. Perform the ATS 4-Sheet Calibration again.

Perform the calibration procedures until they pass.

Note

If a failure occurs, you may need to power cycle the printer to recover.
