Description

BACKGROUND Field of the Disclosure The present disclosure relates to a printing system including a static elimination apparatus, a method of controlling the printing system, and a storage medium. Description of the Related Art A recording medium used in a printing operation (hereinafter referred to as a “sheet”) is conveyed in a state of being statically charged due to a residual charge in an electrophotographic process or slight friction generated with conveyance rollers or guides during the conveyance of the sheet. The static electricity can cause sheets to stick to each other. Additionally, dust and paper dust sticking to printed products can affect the quality thereof. Plain paper has low electrical resistance, which facilitates charge transfer in a sheet, and the amount of charge itself is small. Thus, the static electricity can quickly be eliminated. However, a sheet made with synthetic resin (plastic), such as thick paper, synthetic paper, and coated paper, has high electrical resistance, which makes it difficult to cause charge transfer in the sheet. As a result, sheets, such as synthetic paper and coated paper, tend to be more easily charged and have more residual charge. Additionally, it is generally known that sheets are susceptible to the environment, especially to humidity, and are more statically charged due to a smaller amount of discharge into the air in low humidity environment. If post-processing were to be performed with sheets sticking to each other, that could affect processing of aligning the sheets and the quality of the post-processing, additionally, trigger a jam due to a paper feeding failure or a sheet conveying failure, causing damage to the sheets and the apparatus. To avoid such a risk, it is desirable that static electricity on the sheets after a printing process be eliminated before the execution of the post-processing. A technique is proposed of applying a voltage to a pair of conveyance rollers disposed downstream in a sheet conveyance direction to neutralize the electrification charges on the sheets (refer to Japanese Patent Application Laid-Open No. H11-258881). As described above, the static elimination performed with the configuration of applying a voltage to conventional conveyance rollers (hereinafter referred to as “static elimination rollers”) neutralizes charged static electricity using application of a charge opposite from the charge on a sheet via the static elimination rollers. Thus, the amount of static electricity to be eliminated by the static elimination rollers (the application of a charge opposite from the charge on a sheet to the static elimination rollers) is set according to the amount of the charge on the sheet. This means that the optimum charge adjustment value for static elimination varies depending on the printing environment, such as the humidity and the type of sheet. If a user were to start to print without checking the charge adjustment value for static elimination, a static elimination control could be performed on the sheet with an inappropriate charge adjustment value set. This can cause additional electrification charge on the sheet, resulting in more sheets sticking to each other. SUMMARY According to an aspect of the present disclosure, a printing system, including a static elimination apparatus configured to change a setting of static elimination processing, includes at least one processor and at least one memory that is in communication with the at least one processor. The at least one memory stores instructions for causing the at least one processor and the at least one memory to acquire a type of a sheet to be used in printing processing, acquire a printing environment, acquire a rough indication value for a charge adjustment value for a static elimination corresponding to the type of the sheet and the printing environment, and control a display unit to perform display of the rough indication value for the charge adjustment value for the static elimination and to perform display to give an instruction for continuation of the printing processing.
