How to reset the ink waste tank on xerox wc7545

SOURCE: Xerox Phaser 8560 Waste INk

Although I agree totally, the anwer is no. Althought it appears black, take a piece of it an use it like a crayon. It is a combination of all the color inks combined. So if you take and rub it on a piece of paper it will be a purple color. So threfore would not create proper colors.
Now to save ink, Do not turn the printer off at all. Just let it use its own sleep mode. The power consumption is intermittent to keep the print head warm and uses about the same ammount of electricity as your refridgerator light bulb. The reason being, when you turn off a solid ink printer, it purges the print head of ALL old ink and dumps it into the waste tray. That is part of those weird noises you hear when you cycle up the machine, one is a compressor emptying the print head.
Also, honestly, althogh I am not sure what you are using the machine for. But you would be wise to put that product on a pay per page maintenance agreement. That includes all ink and all service. Some of the parts for those printers are super expensive.
I will say one thing you can do with that waste ink, if you know anyone who has children, they can use them as purple crayons..

Exactly the same problem over here ;-( When replacing the toner recently i forgot to switch of the power, so no reset. I can't find the reset option in the menu, resetting aal settings did not solve my problem.
