The four vertical thin black lines at the beginning and the end of the diagnostic plot show, approximately, the position of the intersection between CIS modules, where this kind of error usually appears. If the error appears outside these areas, call your support representative and report "line discontinuities within a CIS module". Small color differences between adjacent CIS modules When scanning wide plots, sometimes slightly different colors can be seen at both sides of the junction between two CIS modules. This issue, if present, can be easily seen by analyzing patterns 9 of the diagnostic plot at the intersection between CIS modules. Here are some examples. Note the black arrow indicating the scanning direction in these examples. Sometimes the color mismatch between adjacent modules can be enormous, showing a serious scanner malfunction, as in the following example. 118 Chapter 7 Scanning and copying (MFP only) ENWW

between adjacent CIS modules
When scanning wide plots, sometimes slightly
different
colors can be seen at both sides of the junction between
two CIS modules. This issue, if present, can be easily seen by analyzing patterns 9 of the diagnostic plot at the
intersection between CIS modules. Here are some examples. Note the black arrow indicating the scanning
direction in these examples.
Sometimes the color mismatch between adjacent modules can be enormous, showing a serious scanner
malfunction, as in the following example.
