Trouble Shooting Information for C7000VP seriesPage 104 Rev. 2.02010/09/175 Specification-related issues5.1 Description on fixing roller refresh operation and its executiontiming DescriptionThere is a case where the lead edge (cut edge) of paper hit the fixing roller and, thus, causesshiny lines (1mm to 1.5mm wide) in the main scanning direction at the fixing roller intervals. Toprevent this, this machine has a control sequence for automatically refreshing the fixing rollersurface.a. Execution timinga-1. At time of cleaning the corona wirea-2. At time of changing the paper size (from small to large)a-3. At time of post rotationb. Execution conditionThe refreshing operation is executed when the media size counter this machine computesreaches the threshold value.c. Change of time spent for the refreshing operationChanging the setting in user mode > System Settings > Device Management Settings >Fixing Roller Auto Refresh Level will change the length of time spent for refreshingoperation. Changing the setting of this mode will also ease the execution condition of therefreshing operation.c-1. Default value '0': perform the refreshing operation for about 30 sec to 60 sec. (Thetime spent for the operation changes depending on the media size counter.)c-2. Adjustment range: between '-5' (30 sec) to '+5' (330 sec). Changing the value by '1' willincrease/decrease the length of time spent for the operation by 30 sec. Selecting a positivevalue will increase the length of time spent for one operation while a negative value willdecrease it. If the value '-5' is selected, the operation is not executed.d. Conditions other than the aboved-1. Interruption refreshing based on the video counter reading (1 sec)d-2. Refreshing at startup. (3 sec)For these conditions, changing the fixing roller auto refresh level setting will change aparameter (the threshold value of video count), consequently changing the timing at whichthis machine starts the refreshing operation. However, if the setting value is between '-5'and '-1', the operation is not executed.Note: No matter how many sheets of SRA3 or 13x19 size paper are fed, as papers larger thanthese sizes are not used, shiny lines due to paper lint do not occur. Therefore, the media sizecounter, the parameter for roller refreshing, does not increase.
