Limitations of the SD-350/SD-500 system • ­The SD-350/500 Production Booklet Maker system are suited for customers whose booklet making needs will not exceed a yearly average of 30,000 booklets per month. • If sheets entering the SD-350/SD-500 is not uniform and square the booklet quality will vary accordingly. • The maximum recommended number of sheets that can be folded without stapling is 5 sheets of 80 gsm. If there is very low friction between the sheets, running non stapled sets may be difficult. • Staple position may vary on the spine when being square formed with the BookFold Module, especially on thicker booklets. Moving staple position so staple is centered on the spine will reduce this phenomenon. • Staple may be radius shaped (bent) when running with the BookFold Module. Moving staple position so staple is centered on the spine will reduce this phenomenon. • Covers may show marking along the spine of the booklet from the clamp in the BookFold Module. The more pages in the booklet, the more evident the marking. • ­For some white coated stock, such as "Silk type" two sided coated paper, occasional fold roller marks may be observed on the "top side" of the book. • The double feed sensor should be turned off when feeding cover 200 gsm or more from the 7 Cover Feeder. You may also have to turn off this function if you have heavy dark area coverage or covers with different images on them. • ­For jobs with multiple sheets of 200 gsm or heavier, the BookFold Module is recommended for an acceptable output. If a BookFold Module is present in the configuration the BookFold Module shall be turned ON or feed problem at output may occur. • ­Heavy weight media will show image crack in the spine, pre-crease the cover to avoid cracking. • ­Thick books made from coated stock with high friction between each sheet may show permanent "wave like" deformation of the sheets. • Marks from the fold knife may appear on sensitive media on the inner sheet. • ­Marks from side guide motion may appear on sensitive media. • Never run simplex printed sheets from the printer in-line. • Covers may show markings from the Cover Feeder separation process. • Small booklets A5/ 5,5 x 8,5" or smaller may stack poorly on the conveyer. • Sheets may show marks from the "registration rollers" in the RCT module. Changing media will improve the situation. • If corners/edges of sheets by any reason are folded before trimming, result may look as illustrated when corners/edges are unfolded. 94
