Replacement of the developingassembly and starter solved the symptom.* Sleeve ghost is a symptom showing higher density at approximately 60mm from the leadedge of paper in the main scanning direction when outputting halftone images.In order to check if the symptom you are facing is sleeve ghost at the time of occurrence,perform the service mode below to change the peripheral speed ratio of the developmentcylinder. COPIER> OPTION> BODY> SL-RATIOWhen changing the setting to + side, the peripheral speed of the development cylinderaccelerates and the area with high density will become narrower. Conversely, when changing to– (minus) side, the area will become wider.In the event that the symptom is identified as sleeve ghost, make the service mode settingchange below. Field Remedy1. Check toner density in the developing assembly and ATR patch value. Toner density in the developing assembly: Service mode (Level 1) COPIER>DISPLAY> DENS> DENS-Y/M/C/K ATR patch value: Service mode (Level 2) COPIER> DISPLAY> DENS>DENS-S-Y/M/C/K2. Depending on the value of DENS-Y/M/C/K. change the setting below. If toner density in the developing assembly displays +1% or higher, change the settingin service mode (Level2) > COPIER> ADJUST> DENS> HLMT-PTY/M/C/K.If it shows ‘4’ at this point, change it to ‘9’.If it shows ‘9’ at this point, change it to ‘10’. If toner density in the developing assembly displays lower than +1%, change thesetting in service mode (Level2) > COPIER> ADJUST> DENS> P-TG-Y/M/C/K.Input a value adding ‘10’ to current value.3. Conduct the following operations Clean around the developing assembly and wipe the surface of ATR patch sensor withalcohol. Additional Functions> wire cleaning Perform 100 prints for PG10 A3 Additional Functions> wire cleaning Auto gradation adjustment
