PAPER HEIGHT DETECTION
SM 8-11 A860/B390
The amount of remaining paper depends on SP modes 1-908-6, 7, 15, and 16. The
amount of forward rotation depends on SP1-908-4, 5, 13, and 14. Note that there
are two paper size thresholds for each tray: small and middle (this is the same as
for the paper lift mechanism described earlier). Some models only use the small
threshold. The paper size thresholds depend on SP1-908-8, 9, 17, and 18.
The following table summarizes how these SP modes work.
