Auto Dark Adj

When activated, this setting attempts to optimize the amount of toner used when printing with a specific operating point.

Each time this setting executes, the printer performs the following:

• Calibrates its toner density sensor
• Measures the reflectivity of its bare drum
• Prints patches on the drum and measures the reflectivity of the drum through the patches
• Cleans the transfer roll „h Calculates reflectivity ratios and operating points to attain the darkness target of each operating point
• Modifies the EP mechanism as necessary to adjust toner darkness

The cartridge smart chip controls how often this process executes.

Note: No messages are displayed on the control panel to give any indication that this test is running. The device stores the results of its most recent process in the Auto dark adj field on the Menu settings page report.

When deactivated, the printer disables and never executes this process.
To adjust this setting:

1. From the Diagnostics menu, navigate to:
   EP Setup >Auto Dark Adj
2. Choose Enable or Disable.
3. Press OK to save any changes.
