My understanding was FLATBED used -l,-t,-x,-y & ADF used
--pagewidth, --pageheight.
Since you have "unlocked" scan-area/paper-size in
.18 not sure where FLATBED or ADF
references should be included now.

The command worked.
This behavior is confusing:
1. Cannot use defaults for the other arguments when using
--pagewidth [Invalid Argument], but with -x it is
recognized?
2. Using -y without --pageheight does "lock"
both in fi5120C ADF.
3. Using -x & --pagewidth in combination versus -l
& -x?
Will dutifully pass all 4 arguments in .18.
