Abstract
In a method to operate a printer or copier to print to a printing substrate, or in such a printer or copier, toner concentrate is extracted from a toner concentrate reservoir and carrier fluid is extracted from a carrier fluid reservoir. The extracted toner concentrate and carrier fluid are supplied to a mixer where mixing occurs to form a developer mixture. The developer mixture is applied to a developer roller with aid of an electrical field. Given an exchange of least one of the toner concentration reservoir and the carrier fluid reservoir, a strength of the electrical field is modified such that a predetermined desired inking of the printing substrate is maintained even given a change of a toner concentration in the developer mixture due to the exchange.
