The HP C3543A Optional 500-Sheet Paper Tray (referred to in this document as the lower tray) provides your HP DeskJet 1600C and 1600CM printers with a 500-sheet paper source. It holds plain paper in a removable paper tray and you can check the paper supply through one of two windows located on either side of the lower tray. The printer communicates with the lower tray through a special connector located on the rear of the printer. Since the lower tray becomes the default paper source once it is connected to the printer, you must select the printer’s paper tray through your computer.
warning:Power is present in the lower tray whenever it is connected to a power source. To completely shut off power, you must disconnect the power cord from the power outlet.
note:The weight of the paper used in the lower tray should be between 16 lb. and 36 lb. (60 g/m2 and 135 g/m2). For more information about paper weight, refer to the printer’s user’s guide.
note:HP recommends that you use the printer’s input tray when printing on transparency film or glossy media. The lower tray should be used with plain paper only.
