Operation Notes996• When you make a lot of prints from a small image, ink might ooze out fromthe edges of the master, especially under high temperature and when print-ing in two or more colors. In this case, make a new master.• Use ink made within one year. Ink stored for a long period tends to dry slow-ly and yield lower image density.• While making a master, do not leave the exposure glass cover or optional doc-ument feeder open.• In Letter/Photo mode, moire patterns might occur when screened originalsare printed. In this case, make prints in Letter or Photo mode.• When you use originals with light lettering, edges of the letters might beprinted clearly and the inside of the letters might be light. In this case, in-crease the image density.• When marks on the printing paper occur, clean the paper feed roller. Seep.103 “Paper Feed Roller (paper feed tray)”.• If you make a print before the ink on the first print dries, the ink may adhereto the paper feed roller and soil the print. Before printing on the reverse sideof a printed sheet or overprinting on a printed sheet, be sure that the ink onthe first print is adequately dry. See p.103 “Paper Feed Roller (paper feedtray)”.Print Paper• When the paper is curled, correct the curl, otherwise the paper might wraparound the drum or stains might appear.• Postcards and the like do not absorb ink well. Offset images might appear onthe rear side of subsequent prints. Solid image originals will cause offset im-age prints.Originals• If there is no margin or if there is a solid image area near the leading edge ofthe original, make at least a 5mm, 0.2", margin at the leading edge; otherwise,the paper might wrap around the drum or the paper exit pawl might becomedirty and cause black lines on prints.• If you use originals that have bold letters or solid images at the leading edges,you might get prints with dirty edges. In this case, insert the widest marginfirst, or raise the printing speed.• If you use paste-up originals, make sure that the pasted parts hold firmly tothe base sheet. If the thickness of the paste-up originals is more than 0.2mmand the space between the pasted parts is less than 2mm, 0.08", a shadowmight appear on the print.
