It only occurs when the printer has been idle for a period of time, ie. first thing in the morning, or after a break. It doesn’t appear on the paper until it’s printed. No issues once the printer is warmed up. Almost like a burn mark?!</P><P><BR />Occurs on all paper types, and with both Monochrome and Colour Prints.&nbsp;</P><P>Could this be an issue with settings? Or potentially the print head?&nbsp;<BR /><BR />Thanks in advance!</P> Mon, 14 Nov 2022 16:04:38 GMT Skit 2022-11-14T16:04:38Z https://community.usa.canon.com/t5/Production-Printing/PRO-4000-yellow-discolouration-on-print-edge/m-p/393810#M501 <P>Recently our Canon PRO-4000S has started leaving a band of yellow discolouration (approx 5cm wide) to the lead edge of the print.
