An apparatus having an operative mode and a non-operative mode with a method for counting events with a volatile counter and a non-volatile electronic memory having a number N of memory areas, includes counting events with the volatile counter, when the count value has been incremented by a predetermined number M or when the apparatus passes into the non-operative mode, saving the count value to one of the memory areas, with cycling switching of the memory area into which the count value is written; and when the apparatus passes into the operative mode, initializing the counter with the maximum of the count values stored in the N memory areas.

Image forming apparatus for counting images formed by the apparatus

In a networked printing environment having at least a number of workstations of users, a management unit maintains logic storage spaces in a memory, each allocated to a respective user. Digital data files sent from a user's workstation for printing contain an identification of the relevant user and are either of a first type or of a second type. The first type is formed by files which must be printed automatically, and the second type is formed by files which must be stored in the logic storage space of the user in the memory and may be printed only on a command from the operator control unit, which command identifies the relevant file. When handling a print job, the management unit checks, whether the job can be performed completely. If this appears not to be the case, the management unit converts the file into a file of the second type and, if necessary, creates a logic storage space for the relevant user and stores the file in the logic storage space of the relevant user. The same techniques are also used for scan and copy jobs. As a result, the file is not lost but remains available. On a command from the apparatus operator control panel, it can be retrieved and the job resumed.
