Document processing devices and methods are presented, in which the device stores a remaining print unit value in its memory that represents the amount of print units currently available to enable the device to perform the document processing operations, and a programmable computer of the device selectively performs document processing jobs for users and decrements the remaining print unit value until the value reaches zero and the device provides for expenditure of print units according to color content and/or coverage levels determined for a given job.

Pre-paid document processing devices and operating methods

Methods and systems are presented for managing document processing device usage in which a customer accesses a management system to buy and pay for account credits, and to apply print units to specific managed device by conversion of account credits based on current pricing information for the specified account and the particular device at the time of the request.

Methods and apparatus for managing pre-paid printing system accounts

Systems and methods are presented for generating consumable orders for document processing devices and for verifying approved source consumable usage in document processing devices, in which a customer computer receives electronic reports from the devices and from these ascertains whether particular devices will need replacement consumables and also whether non-program consumable products are being used in particular devices. If a replacement will be required, the customer computer presents a proposed order to the customer via prompting content customizable by a reseller. The customer can then accept, modify, or reject the proposed order, and any accepted or modified order is forwarded to an account manager system for automatic placement for consumable shipment from a manufacturer or distributor. If the device has a non-program consumable installed, the customer computer notifies the account manager system and may warn the customer that continued usage may void one or more warranty extensions or other program incentive.
