IQ15 Mottle RAP

This RAP troubleshoots the causes of output images showing image density that varies from
inboard to outboard edges, or randomly throughout the print.
Initial Actions
• Replace the paper in use with fresh, dry paper of the correct specification. Ensure that the
loaded media matches the UI or print driver settings.
• Determine if the Drum Cartridge or any of the Toner Cartridges are approaching end-of-
life. Replace if necessary.
• Perform Max Setup (ADJ 9.1.2). If this does not resolve the problem, continue with this
RAP.
