Checks and Adjustments
Sensor calibration
Using the PC-based diagnostics, you can adjust the sensitivity of the
reflective-type paper edge sensors mounted on the printhead. This adjusts the
sensor to detect the difference between the reflection of the drum and the
reflections from the media loaded on the drum, particularly translucent media.
1.
Turn on the printer and enable the PC diagnostics as explained in the
Chapter 6 topic, “PC-based diagnostics” on page 6-26.
2.
Run the diagnostic test Calibrations — Sensor Calibration ... Load
Cal Media.
Load a hand-fed sheet of Phaser 600 Tektronix-brand
translucent film; use a pre-cut B-size sheet. The printer will advance
the media into the print position.
3.
Next, run the diagnostic test Calibrations — Sensor Calibration ...
Adjust Thresholds.
The printhead will scan across the media loaded
on the drum, and adjust its sensors to the reflectivity of the drum and
the media loaded on the drum.
4.
Once completed, remove the media and exit the diagnostics.
