Ink for the 860 & 8200 are chemically the same. When Xerox developed the 8200, they found out that the yield per ink stick was actually a little bit higher than they put in their documentation.. so the 8200 sticks are a little smaller as well. But I'm a 100% sure they are chemically the same...

The black and white gear definitely have a part number and can be ordered (although they are DC4 part numbers, they also fit the phaser 780.. ordering the complete fuser tray will be a waste of money and more expensive than you would expect). Xerox -has- to give you the partnumber if you ask for...

I don't have service manuals handy at the moment, but hopefully this will help you out anyway. These gears are used as a mechanical fuse within these models, they are designed to be the first ones to break in that particular drive train. Tektronix never considered giving these gears seperate...

I'm a former Xerox hardware specialist. 840/850 printhead are practically identical. so are the 860/8200 printheads. ink was changed from the 840/850 but can be swapped out among these 2 printers (some color differences between the 2 machines though and they use different color lookup tables)...

From the top of my head, press the back and info buttons during power on. This should bring you into diagnostics. Try printing some color test pages from within diagnostics, to rule out any problems with your IP Board. There might also be a dip switch on the print engine board to allow test...

If there is a problem with the kick plate, you should see print quality issues in all colors. Not just one. This would be easy to tell from the diagnostics pages (which jet is blocked, or if there's another problem). Like TCouch said, if there is a problem with this plate, Xerox will replace it...

Do you have access to a service manual, or do you know how to adjust the printhead-to-drum spacing? It shouldn't be needed on the 850 or later models, but it might be worth the try. I know that just the heat of the printhead is enough to keep the drum on temperature, without the paper preheater...

I think you replaced the cartridge too early, the counter may only reset when you put a new cartridge in the machine when there is a "replace" message on the front panel. Don't think it'll reset with a "low" message.

When you look on right the side of the machine through the ventilation holes, you should see the bulbs in the preheater flashing. -Are- they flashing, or are they on solid? I have had this once with a similar machine, one of the triac's on the power supply was faulty and causing the bulb to be...

Some more info on your errors: I've got a strong feeling that you might have taken the upper feed roller assy apart (by accident) and did not put it back together correctly when you were replacing the preheater. Did you try reseating these assemblies? 16,001.43: TCP_THERMISTOR_OPEN The...

15.003.44 - From the service manual: The drum heater is running away. Unplug the printer NOW! Verify that the vent on the right side of the printer is not blocked. Ensure that the drum fan rotates and is installed correctly. 840 & 850 do not have internal diagnostics like the 860 & 8200...

The phaser 800 series don't use a registration assembly & solenoid? Can you please be more specific as to where the jam is occuring? Do you perhaps mean the upper feed roller assy?

I believe that in Europe printheads are only available for purchase by service personal eg trained and certified technicians. Why are you looking to buy a new printhead if the one that is in your machine now is still working? It will probably cost you close to 2000 euros/dollars if you are able...

A tech can not change the purge time. There are 3 types of purges on these machine. If after the first purge, you select the cleaning procedure again within a few minutes the machine will do a heavier purge. And if you do it again after that, an even heavier one. However, 1/4 of an ink stick...

When you remove the paperjam and look at the stripper finger assy (lifts the paper from the drum), is this down or up? If down, this could possibly mean a transfix shaft problem and replacement of the drum transfix assy or a process motor problem. If in the up position, check the support foil...
