Abstract
A printer or copier has a developer station which uses a developer mix such as tone and developer. A temperature sensor is provided in the developer station to sense the temperature of the developer mix. The signal of the temperature sensor is fed to a control unit which effects a control of the copier or printer operation, such as by halting operation, effecting cooling, or triggering a warning signal when the temperature reaches an upper boundary.
Claims13
A method for monitoring and controlling a developer station and its developer mixture of a printer or copier, comprising the following steps:
- producing a temperature signal of the developer mixture by a temperature sensor,
- supplying of the temperature signal to a control unit, and
- influencing at least one operational variable of the developer station by the control unit on a basis of the temperature signal of the developer mixture, said influencing including changing discharging of a photoconductor drum and illumination strength of an exposure unit individually on a basis of acquired temperature of the developer mixture to obtain a uniform print image from a first printing up to the printer or copier being warmed-up for operation.
A method for monitoring and controlling temperature of a developer station and its developer mixture of a printer or copier, comprising the following steps:
- producing a temperature signal of the developer mixture by a temperature sensor,
- supplying of the temperature signal to a control unit, and
- influencing a temperature of the developer mixture by individually changing at least one of discharging of a photoconductor drum and illumination strength of an exposure unit individually on a basis of acquired temperature of the developer mixture to obtain a uniform print image from a first printing up to the printer or copier being warmed-up for operation and by providing at least one cooling unit to keep the temperature within an operational range.
A method for controlling temperature of a developer station of a printer or copier, comprising the steps of:
- sensing a temperature of the developer station to generate a temperature signal;
- comparing the temperature signal to a predetermined threshold;
- and
- inhibiting a developer mix in said developer station from reaching a clotting temperature by pausing operation of said printer or copier upon said temperature signal exceeding said predetermined threshold.
A method for controlling temperature of a developer station of a printer or copier, comprising the steps of:
- sensing a temperature of the developer station to generate a temperature signal;
- comparing the temperature signal to a predetermined threshold;
- and
- controlling photoconductor discharge and exposure illumination strength during warm up from a cold start to a warmed up for operation condition on a basis of said temperature signal.
