1. Model Name
ARM351U/N/M451U/N/EF3
2.Symptom
1. Double feeding of the originals occur due to poor separation, the double fed original
moves over the tail edge of the previous sheet which then detects the paper as a longer
size. Consequently the timing SPPD off is delayed and SPPD-S jam occurs.
2. If many originals are used this can cause a multi feed, all the sheets are fed but do not
make contact SPPD. In this case SPPD sensor cannot detect lead edge of paper and
displays SPPD_N jam.
3. Causes
1. The structure of the separation assembly of the AREF1 was changed to keep the
separation ability longer. However this caused the angle and the pressure to separate
originals were not stable, in this case multi feeding may of have occurred depending on
the type of paper and how they were set.
2. As you can see from the timing chart if double feeding occurs, the following original
activates SPPD and the sensor cannot detect the edge of the original. Consequently it
judges the original cannot reach the sensor and SPPD_N jam occurs.
4. Description
1. In order to improve the stability of the separation function there has been a change to
the Separate Mylar Upper to Separate Pressure Plate SUS Plate. A spacer has been
added between the Separate Pressure Plate and Separate Assist Plate Spring which, is
based on the separate assembly of the AREF1.
2. There will be a change in the SCN ROM firmware so that the timing for the SPFC on
(Paper feed start timing) will be delayed and the following original will reach the SPPD
after the masking time, even if a double feed occurs.
