Before the alignment plate returns, the alignment of the next sheet starts.

As a countermeasure to this error, in the staple mode the first LD sheet and the second LT sheet, after the alignment of the first sheet but before the complete returning of the alignment plate, the second sheet is completely discharged. From that position (the paper has run on to the alignment plate), the alignment treatment starts and the fault has been corrected.

In the case of staple loading in the LT -> LD order, an improvement of the alignability at LT has been made.

BSINo. G00D998 Page 2

When LT is aligned on the staple tray, just before the next sheet (CD) is discharged, the alignment plate presses against the paper. Then it is not pulled back by the knurling belt and skewing as well as other errors can arise. This problem has now been corrected.
