For this reason, it may not be possible to obtain con- sistent printing quality over the entire envelope surface.

  • Page 19: Curly Envelopes

    (4-2) Curly envelopes An envelope tends to curl excessively or become uneven in its thickness since it is constructed by paper which is folded, creased, and seamed in many parts, making the stack of envelopes on the feeder tray unlevel. To avoid feeding problems, the unlevelness of the stack of envelopes on the paper tray must be less than those specified in the following figures.

  • Page 50 Feed roller Reverse roller One-way clutch Figure 2-1-2 FRR System In this system, both the paper feed and reverse rollers are driven clockwise at the shaft. The reverse roller, however, has the torque limiter (one-way clutch) at one end which in normal paper feeding effectively frees the reverse roller from the shaft to turn in counterclockwise direction by means of the friction given by the paper feed roller through the paper.
