Hi guys, I have a Photosmart 8230. After a few lines of printing the black ink fades to almost nothing, all the colours are perfect. There are no error messages. I have done the self cleaning and alignment procedures and wasted a lot of expensive ink. The test page comes out with streaks on the black only. It has been suggested that I take the print head out and immerse it in hot water as a last resort. The question is, how do I remove the printhead? or should I use it as a sea anchor!!
This question was solved. View Solution.

I just did this to a HP Photosmart 8250 which is in the 8000 series range. I assume they are similar. I was an appliance repair man and have done a lot of other tings in my life, so I decided to take a shot at repairing my 8250 rather than junk it. For 3 Years it was great, only one paper jam, and fast great photos, so I didn't want to give up on it. HP will not repair printers for us, I think because it is too labor intensive, and they can sell a new one for what it would cost.

You are welcome, maybe you will have better luck than me. For others that might be reading this thread, my 8250 was starting to work properly, but then the Light Cyan cartridge ran out of ink suddenly, so I replaced it. Now I get the "ink system failure" error, and the printhead is "floating in an gunky ink mess again". It seems like I might need a new printhead? Whatever happened, my printer did seem to quit rather suddenly, so even though I cleaned out the ink mess, I wasn't 100% sure I had it fixed. I did have my fingers crossed.

I have an 8230 with the ink error '0xc18a0406 ink system has failed'. Very frustrating as the printer has (had..) excellent print quality and features, it is just over 3 years old and has only printed 84 pages.... we purchased new HP ink after it looked like the ink had expired (again..) thinking that was the only problem and now this!
I have tried the documented resets in various order, and head clean through the maintenance menu, factory default also through the hidden service menu etc. Eventually disassembled the printer and pulled the motherboard to remove the CMOS battery, left it out for 10 mins and then reinstalled. Checked the left side of the machine and found a large white plastic cog floating around inside the case! It has a hex centre and appeared to be the ink pump cog, have reassembled it onto the minipump shaft and hoped all our problems were solved.... No way! fire it up and it still has the 0xc18a0406 print system failure error whenever you try to print something, followed by print carriage jam errors.
The printer was not used for at least 6 months, is it possible it is dried ink blocking the lines, if so how do you remove the print head/ink pump without wrecking the printer?and what is the best way to clean them out. I see you used hot water on your 8250 print head, is it possible to use compressed air down to line from the ink reservoir for the 8230?

BTW - All the diagnostics were done stand alone today. I removed the USB cable and ran all the diagnotics through the printer menus, all failed when trying to print results. Initially the printer was connected to an XP machine, my laptop runs Vista but the problem doesnt look like host software or drivers, its on the printer itself..

Thank you Modeler, You have given me the courage to tackle my printhead. I dont want to junk my printer as it has been super up to now. I have also been through all the proceedures for getting rid of oxc 18a 1010 to no avail. So here goes !!
