It is not actually a paper jam - when the copier detects a malfunction, it simply stops everything. Paper jams all have "J" codes (J1, J3, etc.).
A CF3 indicates a problem with the ATDC system (Automatic Toner Density Control). The output from the ATDC sensor is outside normal specs.
Possible causes would include the copier being run (and reset repeatedly) without toner, the imaging unit not being properly installed (or not present at all), use of toner not compatible with the unit, a defective ATDC sensor or (least likely) PWB-A.
