Check for any signs of contamination on the ADF CCD module glass.
Use a clean, soft lint-free cloth with isopropyl alcohol (if available) to
clean the glass if any contamination is found.
Note: The ADF module glass can be accessed by removing the
flatbed white cushion from the ADF and lower the exit guide
assembly.
If the problem persists go to step 4.
Check the lower exit guide backside assembly for any signs of
damage to the back ADF white cushion or hardware.
Models X644e/X646e
If the back ADF white cushion cannot be cleaned properly, is
damaged, or is missing, replace the lower exit guide assembly. See
"Lower exit guide assembly removal" on page
If no problem is found with the lower exit guide assembly, go to
step 5.

to the front flatbed white strip. If damaged, replace the complete ADF
assembly. See "ADF complete assembly removal" on page
If no problem is found, check the front flatbed white strip for any signs
of dirt, debris, or contamination. If any problem is found, clean the

available).
