CONDITION The machine prints, but the text is wrong, garbled, or incomplete. Before printing, the machine emits vapor near the output tray. The machine does not print special sized paper such as a billing paper. POSSIBLE CAUSE If you are under the DOS environment, the font setting for your machine may be set incorrectly. Using damp paper can cause vapor during printing. Paper size and paper size setting do not match. SUGGESTED SOLUTIONS Suggested solutions: Change the font setting. See "Changing the font setting" on page 31. This is not a problem. Just keep printing. Set the correct paper size in the Custom in the Paper tab in the printer propeties. See Software section. Printing quality problems If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See the table below to clear the problem. CONDITION SUGGESTED SOLUTIONS Light or faded print If a vertical white streak or faded area appears on the page: • The toner supply is low. You may be able to temporarily extend the toner cartridge life. See page 66. If this does not improve the print quality, install a new toner cartridge. • The paper may not meet paper specifications; for example, the paper is too moist or too rough. See page 33. • If the entire page is light, the print resolution setting is too low. Adjust the print resolution. See the help screen of the printer driver. • A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. • The surface of the LSU part inside the machine may be dirty.
