3,000-sheet stacker Main modules The stacker consists of the following main modules: ● Face-up bin-This bin collects the documents face-up, with the printed information toward the user. Finished documents are not routed to this bin, but the bin supports sheets as they are flipped to the face-down bin. This face-up bin has a capacity of 125 sheets of media (75 g/m2, or 20 lb). ● Face-down (stacker) bin-The face-down bin can collect print jobs with or without offset. The bin has a capacity of 3,000 sheets (75 g/m2, or 20 lb) of letter paper or 1,500 sheets (75 g/ m2, or 20 lb) of ledger paper. ● Offset module-The offset module offsets print requests on a job-by-job basis as the print job is transported to the stacker bin. ● Flipper-The flipper module flips sheets of paper from a face-up position to a face-down position. This function is necessary in order to route the jobs to the stacker bin correctly. ● Paper path-The paper-path module routes the print job after the media leaves the flipper module if the printed media is face-down. If the media is face-up, the print job is routed directly from the flipper module to the face-up bin. ● Controller PCA-The controller PCA controls the entire unit. All stacker-module cables are connected to the controller PCA. ● Power supply-This is the main power supply for the device. The power supply is universal, which means that it can work with products that use 110 Vac to 220 Vac.
