Finally, pull the TransferDrawer out carefully to clear the jam.CAUTION: Forcing the Transfer Drawer open may cause machinedamage resulting in a service call.CAUTION: The use of paper weights greater than 90 lb Index (163gsm) is likely to result in damage to the copier/printer that willrequire a service call. Do not exceed the maximum recommendedpaper weights, except where noted (Jupiter Thinplate 7 pt.).Hints, Tips & Testing ResultsExtensive Xerox testing has shown the following:• When the recommended materials are run as detailed above,with the correct tray, mode, orientation and curl, feedingperformance is good, but will not equal 24 lb LX performance.• Image quality on the recommended papers is good, but shouldnot be expected to equal image quality on 24 lb LX paper. Therough formation of heavy papers increases the likelihood ofimage mottle (light patches) with some images. Mottle is morelikely to occur on images with uniform halftone areas. Ashumidity increases, mottle usually increases.• A small percentage of sheets may exhibit toner on the leadedge. Flipping the paper over or manually curling the lead edgedown will minimize this condition.• Two-sided copying of heavy-weight papers is notrecommended. Paper curl created when running side 1 cancause a high jam rate with side 2. If this occurs, flipping thepaper over for side 1 may improve curl and feedingperformance. Manually curling the lead edge of the side 1imaged sheets down before loading them for side 2 can alsoimprove side 2 feeding reliability. Image quality on side 2 willalso be reduced with certain images. Light image patches(mottle) and deletions are likely on side 2, especially in largehalftone areas.• Toner saturation on electronic originals should be limited to atotal of 280% (70% for each Color). Higher toner saturation canresult in poorly fused prints.• Jupiter Thinplate 7 pt. (181 gsm) has been tested and hasshown improved image quality. Due to its increased weight,more frequent jams should be expected. It is especiallyimportant to load Jupiter 7 pt. curl down. It may be necessary toallow the paper to acclimate to the environment before itsnatural curl can be determined. As with all 17” heavy-weightpapers, only 17 x 11” short-grain Jupiter 7 pt. can be run.Jupiter 7 pt. is distributed by Kirk Paper Company in the USA(714) 978-1619.
