To access Service Mode in C9300 power ON printer with 0, 1, 6, 7 at same time...you can do some good damage in there!! (I warned ya!) Resetting consumables for OKI C7300,C7500,C9300 printer I think! 1. Hold buttons 0 + 1 + 6 + 7 on startup. 2. Press button 0 several times until "DIAGNOSTIC MODE xx.xx.xx" shows. 3. Hold buttons 2 + 3 until "ENGINE DIAG LEVEL 4" shows. 4. Press button 1 to scroll to "COUNTER SET". 5. Press button 2 to scroll through menu items (button 6 scrolls backwards) 6. To alter the value of an item, first press button 3 to select the digit to be altered. The selected digit will slowly flash. (Button 3 moves to the right through the digits. Button 7 takes you to the left.) 7. Then press button 2 to increase the value of the selected digit. Press button 6 to decrease the value. 8. When the changes have been made hold buttons 1 + 3 + 5. The screen will flash three times and then an * will appear on the right of the screen. The new value is set. 9. To leave the counter set menus, turn the printer off. IMPORTANT Each colour toner counter shows life as percentage used. So a toner showing 30% has used up 30% of its toner. 100% would indicate a near empty toner. This is the reverse of the toner life shown from the "usage menu" when the printer is in normal operation, which shows the toners as a percentage life remaining. You will want toner showing 00%. note:this is oposite of what you see in user mode Some models exhange these steps 3) HOLD 0 + 4 "ENGINE DIAG LEVEL 2" shows 4) Press 1 to cycle to "fuser unit" 5) 2 to scroll to TONER REST IS SAME WE WANT TO SET WHAT i GUESS IS AT 100% TO 0%.
