it may be the cartridges are dried up from being stored incorrectly take them back get new ones to rule that out first !! Hope this helps!!

The 8500 and the 8550 do use the same solid ink cartridges. Not sure about the 8560 since couldn't find information about it.

That code is a back stick count failure.
You want to look in your ink loader, see if there is a stick jammed, twisted, broken or in anyother way out of place or hung up in the slot.
Be sure you loaded a 8550 stick also, since the shapes on the different phaser printer sticks are all different.
You may have to carefully remove the black sticks and reload them. You can take a screw and screw it into the ink stick, slide it back and remove.
Most likely you will find a gap in the ink sticks causing the problem. Here are the Xerox support page instructions.

1. Open and close the Top Cover to resolve the problem.
2. If the problem persists, arrange the ink sticks until there are no spaces between sticks of the same color.
3. Check for non 8500/8550 ink sticks jammed in the ink load chutes. If non 8500/8550 ink sticks, whether manufactured by Xerox or by a non-Xerox ink vendor, caused the ink sick jam, contact support to place a service call.

Hi there
The onlty thing I can find close to this is.
Acording to the manual its a ink loader error like your loading the wrong type of ink like the puzzles pieces arent matching and hitting the sensor flags right. Yours by the 8 is referring to the black ink. Anyway go to troubleshooting on the control panel. then to service tools. when in service tools press and hold the up arrow while still pressing the up arrow press the down arrow. the display should say hidden menus. go to diagnostic mode press enter go to funtion menu. then go to clear ISC fault and enter. ISC=ink stick count fault. I hope that helps. Just to let you know Ive had nothing but problems with third party ink and once its in the system its hard to get out so I would watch what im doing with my expensive equipment

If you are using third party ink sticks contact the manufacture and they will, if you use enough of thier product, send you a new print head and send out a tech to change it. Media Science is the most likely source of third party ink.
You can also switch to Xerox ink sticks and the colors will be correct after several purges to get rid of the old ink.

Hi outonalimbwi:
Here is your problem.

37,004.40, 37,005.41 = Reservoir Heaters
37,006.42 = Drum Heater
37,008.44 = Preheat Heater
37,009.45 = (8500/8550) All ink melters
= (8400) Ink Melt 1
37,010.46 = (8500/8550) Ink Melt 1
= (8400) Ink Melt 2
37,011.47 = (8500/8550)Ink Melt 2

Hi,

This means the Yellow ink sticks are jammed in the machine, open up the top of the machine and check if the sticks can slide freely up and down and remove any broken sticks.

If you go to the Xerox.com site and click support and drivers. enter phaser 8550 and there is a printhead update you need to get, You have to fill out a form.
That may be your problem since there is no fault code.
