Nomessage appears when the purge tray is full. Since a paper jamcan occur if the tray is overfilled, empty the purge tray at leastonce a day.To empty the purge tray, simply remove the printed pages.Checking and unloading high-capacity stacker (HCS) binsThe 4635 and 180 NPS/IPS printers can have up to four high-capacity stacker (HCS) bins. The 96 NPS/IPS printer can haveup to two high-capacity stacker bins. Each high-capacity trayholds 2500 sheets of 20lb (80 gsm) paper. (Refer to your XeroxDocuPrint 96/4635/180 System Overview for additionalinformation on the high-capacity stacker bins.)NOTE: If you use large paper sizes such as A3 or 11 by 17inches, the stacker may hold less than 2500 sheets. This is toensure that the stack is at a safe weight for lifting and unloadingby the operator.• You can lower, pull out, and unload any bin not currently inuse, without interrupting printing, as long as another HCS isready to receive paper.• If you select a bin that is in use, the printer begins stacking inthe next defined high-capacity stacker bin if it is available. Ifno stacker bin is available, printing stops.• Once a sheet is delivered to a stacker bin, each subsequentsheet must be within 25 mm (approximately 1 inch) of thelength and width of the first sheet.Unloading a stacker binTo unload a stacker bin:1. Select a bin for unloading by pressing the Bin Unload buttonon the bin control panel. (You can also select the bin forunloading through the printer mimic of the printer controlconsole.)
