Chapter 77-65The DC controller monitors the output of the brush roller home position sensor (PS24) via the side driver PCB to perform this detection.At power ON or after opening/closing the front cover, the DC controller detects the position of the brush roller by checking whether the home position flag fixedon the drive shaft of the brush roller attachment/detachment motor (M18) interrupts PS24 or not.F-7-80[1] Side driver PCB[2] ITB cleaner[3] Brush roller home position flag[4] Brush rollerPS24: Brush roller home position sensorM18: Brush roller attachment/detachment motorDC-CON: DC controllerRelated Error Code:E078-0001 (Brush roller attachment/detachment motor error)When the brush roller for ITB cleaning continues to be pressured (PS24=1) after 5 sec passed from the activation of the brush roller attachment/detachment motor(M18), this status should be judged as this error.E078-0101 (Brush roller attachment/detachment motor error)Attachment/detachment sensor detects if it is placed in the specified position after the operation. It should be error if there is any fault.E078-0011 (Brush roller attachment/detachment motor error)If HP sensor is displaced logically at the time of executing the operation, it should be error.7.9.6 Overview of the Secondary Transfer Assembly 0013-7782imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+The secondary transfer assembly has the secondary transfer outside roller attachment/detachment motor (M17) for attachment/detachment between the secondarytransfer outside roller and the ITB, and the secondary transfer outside roller drive motor (M37) that activates the main roller (the secondary transfer outside roller,the brush roller, the bias roller).Besides, the patch pattern remained on the ITB and the residual toner on the secondary transfer outside roller are collected into the waste toner case beneath thesecondary transfer outside roller by the image stabilization control (ATR, simplified D-half control).The DC controller performs activation/detachment by controlling two motors via the feeding drier PCB.The DC controller performs attachment/detachment for the secondary transfer outside roller to detect the position of the secondary transfer outside roller via thefeeding driver PCB.[1]J3405DC-CONJ1193M18ITB_CLN_HP_SNSAttachment Detachment[2]PS24[3][4]
