This RAP troubleshoots the causes of output images showing image density lower than specification

Initial Actions

• Clean the ROS windows
• Replace the paper in use with fresh, dry paper of the correct specification
• Determine if the Drum Cartridge or any of the Toner Cartridges are approaching end-of-life. Replace if necessary
• Perform Max Setup (ADJ 9.1). If this does not resolve the problem, continue with this RAP.

Step	Procedure	Yes	No
1	Go to Print Test Patterns. Print Test pattern 102. The defect involves a single color.	5	2
2	Go to Print Test Patterns. Print Test pattern 102. Open the Front Door in the middle of the print job (approximately 7 seconds after selecting Start). Extend the IBT. There is a good toner image on the Transfer Belt.	5	3
3	Go to the IQ21 RAP to check the Developer Bias. If this does not resolve the problem, go to the IQ20 RAP to check the 1st BTR bias. If the problem continues, check the ROS for contamination of the windows or misalignment	4	5
4	Check the 2nd BTR for damage or incorrect installation. Go to the IQ22 RAP to check the Backup Roll bias. If the problem continues, replace 2nd BTR Assembly (PL 7.1). If this does not resolve the problem, replace the Transfer Belt (PL 5.3).
5	Swap the affected Drum Cartridge with an adjacent unit. Print Test Pattern 102 The defect moved to the new color.	6
6	Go to the IQ21 RAP to check the Developer Bias. If this does not resolve the problem, go to the IQ20 RAP to check the 1st BTR bias. If the problem continues, replace the Developer for the affected color (PL 6.2). If this does not resolve the problem, replace the ATC Sensor for the affected color (PL 6.2).	7	6
7	Replace the Drum Cartridge
