7 Step 5 - Adjustment of the Auto-Toner Sensor When the developer material is replaced, adjust the auto-toner sensor in the following procedure. If the value of (toner density ratio manual offset control) of the replacing developer material has been changed from "0" (default), return the sub code value of the corresponding color to "0". Important Note: Remove the toner cartridge for the color developer that has been replaced. If the black developer kit has been installed REMOVE the black toner cartridge BEFORE performing this adjustment. If the color developer kit has been installed REMOVE the Magenta, Cyan, and yellow toner cartridges BEFORE performing this adjustment. (1) While pressing [0] and [5] simultaneously, turn the Power ON. The following message will be displayed. (1)Enter ADJUSTMENT Mode Enter Service Mode [0]+[5]+[POWER]ON (2)Authentication screen If a service password has been registered enter the service password and select OK. If a service password has NOT been registered leave password blank and select OK. (2) Key in the code below for the kit that has been installed and press the [START] button. BE SURE THAT THE TONER HAS BEEN REMOVED Code Codes: 2404 = Developer material K 2406 = Developer material YMC

8 (3) The message below will be displayed approx. 2 minutes later and the adjustment starts: During the adjustment, Current sensor voltage (V) shown in (B) automatically changes and gradually approaches to Target value (V) for adjustment reference voltage shown in (A). (4) When the Current sensor voltage (V) in (B) is converged and the Sensor output control value (bit value) corresponding to the value for initial developer material is displayed in (C), the adjustment is completed. When the adjustment is completed, the [OK] button is displayed on the screen. Notes: The values in (A), (B) and (C) vary with humidity. (5) Press the [OK] button to store the adjustment result in the memory. (6) Turn the power OFF and install the toner cartridges.

9 Step 6 - Performing Image Quality Control When any of the following parts is replaced, be sure to perform the Forced performing of image quality closed-loop control ( ) procedure. Photoconductive drum Developer material Laser optical unit Transfer belt 1st transfer roller Drum cleaning blade Needle electrode Main charger grid Image position aligning sensor Image quality sensor (1)Enter ADJUSTMENT Mode Enter Service Mode [0]+[5]+[POWER]ON (2)Authentication screen If a service password has been registered enter the service password and select OK. If a service password has NOT been registered leave password blank and select OK. Code Item to be adjusted Contents 2742 Forced performing of image quality closedloop control (3)Key in [2742] and press the [START] button. Code (4) WAIT is displayed. (5) When the adjustment finishes normally, the equipment returns to the initial state of Adjustment Mode. (6)Turn the power OFF at the main switch.

10 Step 7 - PM Counter Reset The procedure outlined below is for resetting the BLACK developer kit. Follow the same procedure when installing the COLOR developer kit for this printer. DO NOT reset the OZONE FILTER counter when replacing the COLOR KIT as this is only performed with the black developer kit replacement. (1)Enter PM Support Mode Enter Service Mode [6]+[START]+[POWER]ON (2)Authentication screen If a service password has been registered enter the service password and select OK. If a service password has NOT been registered leave password blank and select OK. Reset for the Black Developer Kit (1)Highlight the CLEANER/DRUM/CHARGER (K) counter and select RESET. This function resets: Drum (K) Drum Blade (K) Grid (K) Main Charger Needle (K) Charger Cleaning Pad (K) (2)Select Initialize. Once Initialization is complete you will return to the Home screen above.

11 (3)Highlight the OZONE FILTER REAR counter and select RESET. (4)Select Initialize. (5)Page down to page 2 of 4 and Highlight the DEVELOPMENT UNIT counter and select SUB UNIT.

12 (6)Highlight the BLACK DEVELOPER counter and select RESET. (7)Select Initialize. Once Initialization is complete you will return to the previous screen above. (8)Highlight the DEVELOPER FILTER (K) counter and select RESET.
