Abstract: A method, system, and article of manufacture for performing computation on an electronic message without the involvement of a user is provided. By including a command instruction in an electronic message which identifies an application provider for performing the computation and includes parameters and values to indicate what information is to be provided to the application provider, the message can be sent by a user and computation can be performed without the involvement of the user. The method, system, and article of manufacture is designed to intercept the message, control the computation, modify the message, and deliver it to the intended recipients.

Abstract: A squeegee roller system for removing excess developer liquid from the developed-image-bearing photoconductive surface of a drum or the like in which a freely rotatable squeegee roller having a covering of predetermined hardness is biased against the drum to cause excess developer to flow into a receptacle having a weir over which the liquid flows back to the supply tank and in which a fur or pile-covered cleaning roller contacting the squeegee roller is driven in the opposite direction from and at a speed slightly greater than that at which the drum drives the squeegee roller with lower portions of both rollers passing through developer liquid retained by the weir and in which a cleaning blade is biased into engagement with the cleaning roller.
