Location: Inter transfer belt assembly Subject: Measure against mottled blank on image occurred when using papers of rough surface (optimization of primary transfer current, etc) Detail: Background: Although the reduction in thickness of ITB as a measure against mottled blank, and others were announced previously, this bulletin offers the following information for further improvement in images. When using papers of rough surface, mottled blank may occur at the high-density area on images. Toner tends to have too much adhesion to Inter. Transfer Belt (ITB) at the primary transfer of image. Because of this, if papers of rough surface are used, uneven secondary transfer of image will occur, and occasionally causing mottle blank on output images. * Primary Transfer Roller Set (FY7-0429-000), which is newly set up as a service part this time, should preferably be used along with Inter. Transfer Belt Set (FY7-0408-000) that was previously announced. Image quality cannot be guaranteed by replacing Primary Transfer Roller Set (FY7-0429-000) only. Upgrading to DCON v33.09 or later and to System v45.02 or later is necessary to produce an effect of Primary Transfer Roller Set (FY7-0429-000).

Implement the following to improve the primary transfer performance. 1. Widen Nip Width [D] between Primary Transfer Roller [3] and ITB [2] to disperse the nip pressure. A. Change the spring pressure (C,M,Y,Bk) [B] of Primary Transfer Roller [3]. B. Move the position of Primary Transfer Roller in the direction of [C]. C. Increase the diameter of Primary Transfer Roller [3]. 2. Decrease the discharge current of Primary Transfer Roller [3]. A. Increase the resistance of Primary Transfer Roller [3]. B. Optimize Primary Transfer Roller current. Upgrade DCON firmware to v33.09 and System firmware to v45.02.

Servicing Work: The steps below are carried out to further improve mottled blank. When the old type Primary Transfer Roller (life: 500K images) reaches the end of life, replacement must be made with Primary Transfer Roller Set (FY7-0429-000), not Primary Transfer Roller. Step 1. Check to see if the thin-type Inter. Transfer Belt Set (FY7-0408-000) previously informed has been installed. If it hasn't, it is recommended to install the thin-type Inter.Transfer Belt Set and Primary Transfer Roller Set to be mentioned in Step 2 below simultaneously. Step 2. Install Primary Transfer Roller Set (FY7-0429-000) that is newly set up as a service part.

Spring for Y, M and C 7. Spring for Bk 8. ITB Installation Auxiliary Sheet 9. Stratification Lable: 1pc 10.

*After the replacement, attach Stratification Label mentioned in 9 above on one side of ITB unit according to the procedure document below for easy stratification.

Step 3. To optimize the primary transfer current, upgrade the version of DC controller to v 33.09. *At this time, combination with System Software v45.02 or later is necessary. * Even when System Software is upgraded from an older version to v45.02 or later in the field, the setting value of service mode item "ITB-TYPE" does not change automatically. Therefore, after replacement to Primary Transfer Roller Set (FY7-0429-000), the setting value of the service mode item must be changed to '2' manually. * ITB-TYPE does not accept the setting value '2' until Dcon v33.09 or later and System v45.02 or later have been installed. (Level2) COPIER > OPTION > IMG-TR > ITB-TYPE 0: Old type ITB 1: Only ITB is the thin (new) type 2: ITB is the thin (new) type, and Primary Transfer Roller is the new type. * The products in which the new type Primary Transfer Roller was installed during manufacturing already have ITB-TYPE set to '2' at factory shipment. * Executing RAM Clear automatically changes the setting of ITB-TYPE to '2'. Therefore, at field service, it is necessary to rewrite the setting of this service mode according to the situation of countermeasure against mottled blank.


iRAC9000-037 Points to Note About Service Work: The products with the primary transfer roller set (FY7-0429-000) installed are not compatible with the old-type parts of the following 1 to 5. Therefore, use these parts only for the products with this measure not taken. 1. FC8-4401-000: primary transfer roller 2. FU7-2449-000: compression spring (Bk) 3. FU7-2450-000: compression spring (Y, M, C) 4. FC8-4383-000: bushing (rear) 5. FC8-4387-000: bushing (front) When the above parts are out of stock, the parts settings for them are deleted. If it is necessary to replace a single part of them after deleting the parts setting, implement replacement with the primary transfer roller set (FY7-0429-000) as a set.
