Gap Adjust
The setting adjusts the minimum gap between sheets. Increasing this value may reduce curl of some printed
media and eliminate some output bin stacking problems. However, increasing this value also results in slower
overall performance, measured in pages per minute.
The range of values is 0 to 255, and the default value is 0.
To adjust this setting:
1 From the Diagnostics menu, navigate to:
EP Setup > Gap Adjust
2 Press OK or touch to save any changes.
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
• 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.
