I have a Xerox Phaser 8400 "solid ink" printer. Black print head appears to be clogged. I've run through all the cleaning cycles several times and it seems to only get worse.
The print head costs $800!
thanks in advance,

Re: clogged print head
What you can try is going onto the Xerox.com site and loading what is call Jet Substitution it will change the ports being used.
That could help.
Load it to your laptop and then run. Sometimes helps.
Unfortunatly that is a very expensive print head.

Try printing a light stripes test page (Troubleshooting, print quality problems, troubleshooting print quality page).
If you do not appear to have many missing jets but the colours are all just wrong it may be that the ink has gone stale. Run a couple of head cleans and you should see the colours start to improve. If it is getting better, all you can do is keep running head cleans until you have replenished all the ink in the printhead well. This problem is common in situations where a lot of black and white printing is done, with very little colour. Alternatively, it could be that your wiper/cleaning blade is not cleaning the head properlyand is smearing the different coloured inks across the head, or possibly that yourprinthead is leaking colours but I think the first solution should solve your problem. Hope this helps.
The error is normally caused by the print head wiper being stuck to the print head or the print head pivot block being contaminated with spill over ink.
To clean the block you remove the left side cover. There is a stainless steel block about 1 inch by 1 inch about midway back on the lower frame. It would most likely have a lot of yellow ink in it.
If the wiper blade is tacked to the print head, you would remove the right and left cover. then remove the ink loader. ( where you place the ink sticks.). Once you remove the ink loader you are in the print head drum area and would gently detack the blade from the print head, then run the eliminate light stripes in the troubleshooting menu.
What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem. You can try googling. Phaser printer print heads or phaser printheads. There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head. Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads. Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP. The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.
That is a print head tilt error. Either the print head pivot block is contaminated with ink or the wiper blade is tacked to the print head.
Let me know if you want to try to resolve it yourself, I will send you directions.
Replace the maintenace kit and then in the menus run eliminate light stripes and eliminate smears.
There really isnt much else to do.
What you do when you run the light stripes and smears modes the machine removes all the ink from the print head, turns on a compressor and blows out the jets on the print head.
There really isn't a "cleaning " procedure as with a laser printer. If the maintenance kit is good, it pretty much maintanes itself.
I would guess Orange = light red (magenta) indicating a problem with a clogged ink nozzels on the print head.
So might need an engineer if the cleaning option (on the printer menu) can't fix it.
The first obvious question is, "Does it have blue ink/wax?"
Is it displaying any errors?
Have you tried the Xerox support site? They have a fantastic utility that can connect to your printer and diagnose many problems. Here's the URL for the utility:
They also have a wealth of information in their knowledge base. Here's the URL for the support page for the Phaser 8400:
Did anything happen before the blue quit printing?
Have you tried running a cleaning cycle?
