4. Measure to alleviate problems of jams in the center tray.

1.Model Name: SD-2260

2.General: The attachment of a suction plate pressure sheet to the back side (lower side) of the

suction unit of the center tray unit was reported in technical report DTE-286. Due to the influence of sagging of the copy paper as it is discharged from inside the center tray, however, the leading edge of the copy paper sometimes comes in contact with the static electricity discharge sheet attachment plate, causing the copy paper to jam. As a measure to alleviate this problem, the suction plate pressure sheet has been added once again.
