Color 570 started with random yellow specks on prints to full printer failure with toner everywhere

Product Name: Xerox Color 550/560/570 EX Fiery Controller
Operating System: Windows 7
Basically for the last few thousand clicks, we noticed yellow specks appearing all over the prints. We'd pull out the drum tray and there would be a bit excess of yellow toner. All colors have a little floating around normally but this time there was a lot more yellow. We'd wipe it all down and all would be good for a short while then back to specks.

We replaced the yellow drum and it worked perfect for like 5k clicks...then it came back with a vengeance. After removing the new yellow drum we put in, we noticed that the little sliding door at the end of it where toner comes out (goes to waste container?) was blocked by a completely solid block of yellow/grayish toner. It was literally like a rock that I had to chip away with a screwdriver to get the door to close. We then noticed that toner was piling up inside the printer after we unclogged the door.

However, the little chute that door dumps into is completely blocked up as well. So after fixing the door on the drum, it was able to push out toner freely but it is intead collecting inside the printer on the fuser tray. It's a mess! (pics attached)

The machine is in an open warehouse like environment without any insulation. It gets SUPER cold and SUPER hot in there throughout the seasons. We had a lot of rain the last few weeks. We are thinking maybe the humidity caused the toner to clump up and block everything.

Do you guys think this is something I can fix by cleaning up the clogs and cleaning up the excess toner or should I have a tech come out? We have a lot of big jobs we need to finish and nobody can get out here until late next week :(

Hi,

The differences in temperature and humidity make the toner to be clogged. 

You will need a tech to clean or to replace if it is something broken in the residual system (in the back of the machine).

Part no. for possible broken parts are 049K27440, 093K20000 and 052K98931.
