Hi! My name is ***** ***** I will be assisting you. Let's get started!
Did you replace the drum or the toner? A common mistake is replacing the toner and not the actual drum.
Sure, come back here on Monday and we can continue.
I apologize -- I am back in the office now. When are you free again?
1. Turn machine on while pushing and holding the TWO up/down menu buttons at same time.2. Menu window will show "OKI USER"3. Scroll to " Engine Dialog Mode" is indicated. Push Enter button.4. "Diagnostic Mode xx.xx.xx S-Mode is indicated.5. Scroll to "NV-Ram initial" is indicated. Push ENTER.6. Window shows "NV-Ram- Initial Table 1".7. Push ONLINE and ENTER Buttons simultaneously and HOLD for 10 seconds after you see "Executing Reset" appear in menu window.8. Restart printer.
Are you able to press Enter on that screen?
On the Mode screen that you cannot bypass..
Press and hold both Enter and Online simultaneously until you see Eng Diag Level3
Press the +/- until you see Local Parameter Set
Press + or - until it displays Factory Mode; if it displays Factory Mode Twice with an asterisk next to one then it is in Factory Mode; Press Enter, Press + or - until it displays Factory Mode & Shipping Mode on the display; then press and hold On-line & Cancel simultaneously; when it stops blinking an asterisk should be displayed next to Shipping Mode, which becomes the default mode.Power printer off then on to complete the procedure
Okay, let me know how it goes.
Press and hold Back, Enter, Plus and Minus on the Diag Mode screen
Please let me know what it says in the morning
At this point, it looks like it might be a hardware issue with your printer.
How old is the printer?
I understand that it is unlikely for two printers to fail at the same time with the same issue but it is possible. The steps that I have given you above were to reset the drum counter but none of the steps are working.
