The HP T3V30A adds a 2,700-sheet high capacity A4 paper tray with a stand to HP's A3 colour LaserJet Enterprise and Managed printers, cutting down on paper reloads in high-volume print rooms and busy shared offices. It sits beneath the printer, raising it to a practical height, and is compatible with the HP Color LaserJet Enterprise M751n and M751dn, M856dn, Color LaserJet Enterprise MFP M776dn and Color LaserJet Managed E75245dn and E85055dn. The tray operates from 10 to 32.5 degrees Celsius. It measures 986 x 659 x 326 mm and weighs 33.4 kg. Choose it when your printer runs through several reams a day and you want one large A4 source rather than several small trays.
