Stacker The stacker contains a heated roller to remove the curl from the paper. To change the temperature of the roller, select the icon on the printer's front panel, then Accessories > Stacker > Select temperature level. There are three options: ● Normal is the default and recommended setting. ● High sets the roller to a higher temperature, which may be useful for particularly stiff paper. ● Low sets the roller to a lower temperature, which may be useful for paper with a particularly sensitive coating. Change paper rolls while using the stacker 1. Remove the stack of cut paper from the stacker in order to make the stacker easier to handle. 2. Detach the stacker from the printer: first one side, then the other. 3. Change the rolls in the normal way: see Unload a roll from the printer [4520] on page 36 and Load a roll into the printer [4520] on page 33. Clean the exterior of the stacker See Clean the exterior of the printer on page 112. Clean the stacker rollers WARNING! The stacker becomes hot during use. Before cleaning, switch it off and give it time to cool. Ink tends to stick to the main stacker roller and the small output rollers, which should therefore be cleaned regularly using a fabric cloth dampened with water. The frequency with which cleaning is needed depends to some extent on the paper type in use. ● For plain, coated or heavyweight coated paper, once a month may be sufficient. ● For translucent, vellum, glossy or natural tracing paper, cleaning may be required once a week even with the slowest print modes.
