Toner patch sensing service check
Pre‑check procedure
1
Enter the Diagnostics menu, and then navigate to:
Printer setup > EP setup > Toner patch sensor adjust > Clean sensing and laser optics
2 Allow the cleaning operation to run for three minutes.
3 Enter the Diagnostics menu, and then navigate to:
Printer diagnostics & adjustments > Color alignment adjust
4 On the AA adjustment row, touch Start.
Note: This triggers the auto align routine which performs the color alignment error corrections.
The following lists the dierent auto align routine results:
• AA Result 1—Failed to complete
• AA Result 2—Normal data deficient
• AA Result 3—All OK, normal data within limits
• AA Result 4—Normal exceeds sense limits
• AA Result 5—Normal exceeds margin limits
• AA Result 6—All OK, normal corrections applied
• AA Result 7—Coarse data within limits
• AA Result 8—Coarse data
deficient
• AA Result 9—Coarse failed to converse
• AA Result 10—Coarse exceeds sense limits
• AA Result 11—Coarse exceeds margin limits
• AA Result 12—Coarse corrections applied
• AA Result 13—Normal exceeds skew limits
• AA Result 14—Coarse exceeds skew limits
• AA Result 15—Coarse new ITU speed
• AA Result 16—AA characterization successfully completed
• AA Result 17—AA characterization deficient, using defaults
• AA Result 18—AA manufacturing mode successfully completed
• AA Result 19—AA manufacturing mode deficient, not updating the results
5 Enter the Diagnostics menu, and then navigate to:
Printer setup > EP setup > Toner patch sensor adjust > Full calibration
Note: This triggers the auto align routine (0.42mm—Normal range only).
