Wrong answer. This is a four digit entry. There is no M,N or I in the scrolling alphabet.
Expert:  Dustin replied 10 months ago.

In that case, then the system admin password ***** already been set.

You will need to refer to the field service manual on how to enter service mode and clear the password.

You can get the field service manual here. https://www.tradebit.com/filedetail.php/152280678-magicolor-4750-field-service-manual

And that will also help with almost every conceivable repair or issue you might have with the machine, its a very solid investment. And will show you how to remove or reset the password ***** to its default.

OK, I managed to get into the maintenance menu. I reset the counter - yet nothing was accomplished. I still get the "end of life" message. DO I have to change the fuser after I reset the counter? Or, can I change the fuser prior to resetting the counter?Thanks
Expert:  Dustin replied 10 months ago.

Youre mentioning end of life, and the fuser. So im assuming that the end of life message you are getting specifically mentions the fuser?

And have you replaced any parts already?

Customer: replied 10 months ago.
I did replace the parts, and I am still getting the message after trying to reset the counters.
Expert:  Dustin replied 10 months ago.

Lets remove the fuser then.

and while its removed, unplug the machine, wait five minutes, plug it back in.

And then, reset the counters. Only then, insert the fuser. Any change?

Customer: replied 10 months ago.
Sorry, did not work. Should I return the original imaging unit. Restart the printer, and then try installing the new imaging unit again?
Expert:  Dustin replied 10 months ago.

That would be worth a shot.. Once you have returned the original unit.. reset the counters ..

Verify how it behaves.. And then remove the unit, reset counters, insert unit, reset counters.

If that doesnt work, youre going to have to replace the chip on the imaging unit, you can get the needed reset chips here http://amzn.to/20wOEB0

OK, first, I got it wrong. I do not need to reset any counters since this is an Imaging Unit and not the FUSER.Upon further reading, it should have reset automatically when I replaced the Imaging Unit. The initial replacement for the K unit was damaged and I got a new one. I also replaced the Y, M and C imaging units at that time since they were all running low.With the new imaging units, K went to "end of life" status. Since then, nothing is working. Y,M and C still show status as running low.Is replacing the ID chip the only route to go?
Expert:  Dustin replied 10 months ago.

the drums also have counters ( and chips inside them that keep track of the units usage )

It would help if I knew the exact word for word error you are getting on screen. And any codes along with it.

Customer: replied 10 months ago.
No message code, but message "I_UNIT END K"
Expert:  Dustin replied 10 months ago.

That tells us its the black imaging unit you need to replace.

Is black the one you replaced?

Customer: replied 10 months ago.
I did replace the black unit. Also, the Cyan, Yellow and Magenta - which all still have the running low message.None of which reset any message after replacing them.
Expert:  Dustin replied 10 months ago.

Then you need new chips on those imaging units.. Or you need to replace the imaging units. Its much cheaper to get the new chips.

And this video is very close to your model, and shows how to replace those chips.

Dustin,The 4750DN does not have a Chip ID. I pulled apart one of the old ones. Nor, does the end of imaging drum come apart.I though that I would need to update the firmware - but it is at the latest level. I went through the menus - there is nothing that resets the counters for the imaging drums.What is your next suggestion?John Mc Gill
