IQ3 Low Image Density/Nearly Blank/Uneven Density RAP

This RAP troubleshoots the causes of output images are completely blank or has extremely
low density
Initial Actions
• Clean the ROS window
• 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.
• Check the Contact Arms are in the proper position (PL 6.2).
• Perform Max Setup (ADJ 9.1.2). If this does not resolve the problem, continue with this
RAP.
Procedure
Print Test pattern 59 for each color (C,M, Y, K) at 40%. The defect involves a single color.
Y N
Panic stop the machine by removing the IBT Cleaner Assembly (PL 6.1). Print Test pat-
tern 59 using Cyan 40%. Open the Front Door in the middle of the print job (approximately
7 seconds after selecting Start). Remove the Fuser. Remove the paper. There is a good
toner image on the Transfer Belt at the 2nd BTR/Back Up Roll nip.
Y N
Go to the IQ21 RAP to check the Developer 1st BTR. If this does not resolve the
problem, go to BSD 9.5 and check the circuit.
If the problem continues, check the ROS for contamination of the window.
Check the Contact Arms (PL 6.2) are in the proper position.
Check the 2nd BTR for damage or incorrect installation. If the problem continues, replace
2nd BTR Assembly (PL 2.7). If this does not resolve the problem, replace the IBT Belt (PL
6.2).
Replace the Developer Housing (PL 5.2) and material for the problem color.
