Arrangement for printer equipment for monitoring reservoirs that contain printing medium

An arrangement for printing equipment, comprising:

• a) a reservoir means for accepting a printing medium, said reservoir comprises an electronic memory means for storing status data of the printing medium relevant to a printing operation,
• b) means for acquiring a current fill status of said reservoir means and for writing a memory value corresponding to the current fill status into said electronic memory means,
• c) means for acquiring the memory value of said electronic memory means corresponding to a minimum supply of printing medium and for at least one of triggering an alarm signal and blocking a printing operation,
• d) said electronic memory means being irreversibly modified by said means for writing a memory value so that writeability of said electronic memory means is suppressed after the memory value corresponding to the minimum supply of printing medium has been reached,
• e) means for storing information about service life of the printing medium as status data,
• said memory means comprising a timer having a preset basic setting and means for irreversibly modifying a counter reading of said timer in accord with current service life of the printing medium proceeding from the basic setting.
