Adjustments/Calibrations - Performs adjustments, calibrations or operations essential to the
performance of the printer. For complete walk-through procedures, see
"Calibrations" on
page 6-2.
(ADC) Auto Density Control - Density Calibration: Verifies ADC operation, replacement ADC
tag number is entered, then the operation is tested. The following functions are all part of the
Auto Density Control.

(ATS) Auto Thickness Sensor
ATS 4-Sheet Calibration - Verifies ATS operation. Test requires 4 sheets of premeasured
media. A fifth sheet of paper, the bottom sheet, is recommended to prevent 'tray empty' issues.
Media is picked from Tray 1 (MPT).
"Automatic Thickness (ATS) Calibration" on page 6-4 for the
detailed procedure. The following tests are all part of the ATS Thickness Sensor.
Edit Thickness Data - Thickness Calibration: Premeasured media thickness can be entered
here in units of mils or microns, the calibration procedures use Microns. Input is constrained,
when necessary, to system-dependent limits independent of actual user input values. Limits are
70 - 200 um.
