Abstract
A technique for controlling a developing voltage of an image forming device, which is capable of properly controlling the developing voltage according to thickness of the printing paper includes: setting a specific printing paper flag according to a key input generated by selection of specific printing paper by a user; checking whether or not the specific printing paper flag is set; and, upon determining that the specific printing paper flag has been set, controlling the developing voltage so as to be a developing voltage value corresponding to the proper amount of toner during forming an image on the specific printing paper.
Claims8
A method of controlling a developing voltage of an image forming device, comprising the steps of:
- setting a specific printing paper flag according to a key input generated by selection of specific printing paper by a user;
- checking whether or not said specific printing paper flag has been set and said specific printing paper fed;
- and
- upon determining that said specific printing paper flag has been set and said specific printing paper fed, controlling the developing voltage so as to be a developing voltage value corresponding to the proper amount of toner during forming an image on said specific printing paper.
A method of controlling a developing voltage of an image forming device, comprising the steps of:
- setting a specific printing paper flag according to a key input generated by selection of specific printing paper by a user;
- checking whether printing paper has been fed automatically;
- checking whether or not said specific printing paper flag has been set and the printing paper manually fed;
- and
- upon determining that said specific printing paper flag has been set and the printing paper was manually fed, controlling the developing voltage so as to be a developing voltage value corresponding to the proper amount of toner during forming an image on said specific printing paper.
