Before stored MH or MR encoded fax data is transmitted, the fax library checks the integrity of every scan line in the data stream. Scan lines that do not have the correct pixel count are replaced. (If the image was stored without scan line errors, the data being transmitted should have no bad scan lines.)
When a scan line error is detected, Bad Line Replacement (BLR) automatically replaces the bad scan line(s) with the last scan line that had the correct pixel count.
To determine the number of bad scan lines detected and replaced on the transmitted, call ATFX_BADSCANLINES( ).
MMR encoded data always requires the use of T.30 Error Correction Mode (ECM). The capabilities of the receiving station determine if ECM is used.
