- Selector 1: Printout of the stored image data of an unsent document onto an error

report

This selector determines whether or not to print out the 1st-page image data of a
document onto the error report if the document image data stored in the temporary
memory cannot be transmitted normally.

- Selector 2: Erasure of the stored image data of an unsent document at the time of the

subsequent in-memory message transmission

If in-memory message transmission fails repeatedly when selector 1 is set to “1,” the
temporary memory will be occupied with image data. Setting selector 2 to “1” will
automatically erase the stored 1st-page image data of an unsent document at the time of
the subsequent in-memory message transmission only when recording paper or toner runs
out.
