157Performance ConsiderationsForms TypeThe paper feed tractors on the ZTP printer push the paper up through the print station instead of pulling itthrough, as in the standard pedestal printer. This limits the variety of forms the ZTP printer can use. If theforms do not fall within the range specified in Table 15, dot compression, line separation, and jammingmay occur. The user should match the media to the application to ensure acceptable print quality. Also,because paper is pushed from below the print station, the last form in the tractors may not print fully ormay not be presented to the printer exit for retrieval.All paper used in the ZTP printer requires standard half inch spaced tractor feed holes. Cut sheet andcontinuous friction fed paper is not supported. The forms specified in Table 15 can have no more thanone form per page horizontally.Table 15 Forms TypeDescription Length Width(edge to edge)One to three part, continuous, with carbon, fan-folded,edge-perforated paper forms 3 to 12 inches 7 to 16.5 inchesOne to four part, continuous, with carbon, fan-folded,edge-perforated paper forms 3 to 12 inches 7 to 12 inchesOne to four part, continuous, carbonless, fan-folded,edge-perforated paper forms 3 to 12 inches 7 to 16.5 inchesOne to six part, continuous, carbonless, fan-folded,edge- perforated paper forms 3 to 12 inches 7 to 12 inchesForms with a paper weight of 20 to 100 pounds and amaxi- mum thickness of 0.025 inches 3 to 12 inches 7 to 16.5 inchesForms with a paper weight of 18 to 100 pounds and amaxi- mum thickness of 0.025 inches 3 to 12 inches 7 to 12 inchesForms with all approved types of interleaf edge attachmentexcept those using metallic or other hard devices 3 to 12 inches 7 to 12 inchesNOTE: If you use forms outside these limits, the print quality may not be optimum, the printer may losetop-of-form, or the frequency of paper jams will increase.Paper JamsPrinter jams can occur if you tear off the form incorrectly. If you experience two or more paper jams perbox of forms, follow these guidelines to help reduce jams:• Position the lower paper guides properly• Align the paper web tightness properly• Position the form perforation against the tear bar• Time the tear, while the paper is not moving• Direct the tear force toward the user and across the tear bar, not upward.
