Table 5-4. 2000-sheet Input Tray Paper Quantity Switches Table 5-5. 2000-sheet Input Tray Paper Size Switches When the Paper Handling Controller on the printer sends an input command to the Controller PCA on the 2000-sheet Input Tray, the Paper Deck Driver runs the Pickup Motor to rotate the Pickup, Feed, and Separation Rollers. As the Pickup Roller turns, the paper feeds into the Vertical Transfer Unit (VTU) and passes through the PS31 and PS32 sensors . If the paper fails to reach the PS31 and PS32 sensors in the VTU within the allotted time, the Controller PCA on the 2000-sheet Input Tray assumes that a paper jam has occurred.
The 2000-sheet Input Tray stops the operation and reports the paper jam to the Paper Handling Controller on the printer. A paper jam message appears on the printer control panel display. Hardware malfunctions are also displayed on the printer control panel. 120 Chapter 5 Functional Overview C4085-91087 SW601 SW602 Remaining Paper Off Off 100% On Off 75% On On 50% Off On 25% Paper Size SW701 SW702 SW703 SW704 Ledger (portrait) Off On Off Off A3 (portrait) On On Off Off B4 (portrait) Off Off On Off Legal (portrait) Off On On Off Letter (landscape) Off On Off On A4 (landscape) On On Off On
