[. . . ] Paper Jam · Confirm paper weight setting in the OCP. · Use paper (grain long) with fibers that run in parallel with the paper feed direction. 5-6 Troubleshooting Printing Notes Paper jams (e. g. E134) may occur at the Switch Back Station, when using thick (stiff) paper. Banding may occur when printing half tones. This happens when paper enters the fuser unit or exits the regist rollers. Print position may gradually shift backward on the page when printing on thick paper. Multiple paper feed may occur if you are using paper that does not meet specifications. Paper jams (E118, E119, E128, E134, etc. ), stacker jams, poor stacking accuracy and poor staple accuracy may occur on paper with too much curl. Print start position may change based on paper size and weight. Print density may degrade when printing more than 30% print coverage. Stacking accuracy may degrade when printing thin long paper. The paper exit rollers on the Finisher may quickly become contaminated when printing outside of the printable area. Print density may darken after replacing the developer mix. Scratches may occur if the OPC Drum is touched. To avoid paper jams, print speed is reduced when printing with tray combinations. Perform a test print to check print quality prior to starting daily print jobs and prior to starting jobs requiring high print quality. Continuous half-tone or solid black printing may cause print quality degradation. Frequent high black-to-white ratio and high-density printing can cause print quality to degrade. Check the print quality periodically and clean the inside of the printer. A high black-to-white ratio on duplex print jobs can cause paper to stick to the finisher. To avoid this problem, remove paper from the finisher stack frequently or lower the print density. Print density may be high for several thousand pages after powering on the printer. [. . . ] Area of the physical page in which the printer is able to place a dot. A destination for a sequence of stored data or programs awaiting processing, as in files waiting in line to be sent to the printer. Glossary-4 R RAM. A type of internal memory that stores data temporarily. A type of internal memory that is used to store programs and data vital to the printer's basic operation permanently. S SCSI. [. . . ]
