Introduction
Is your HP Photosmart C309g's printhead clogged, producing streaky output or not printing a certain color? This guide will show you how to unclog the printhead on this printer.
Here is the one thing I would like to clear up now: The cleaning stepssteps to clear the printhead I used here will work with otheron all Inkjet printers, and even fully integrated cartridges but the printhead removal steps and the steps to bypass the printhead initialization are tied to this model and similarly aged'''ANY AND ALL DISASSEMBLY STEPS GO TO THE HP PHOTOSMART SERIES WITH 564 printers-ifINK!''' If you use this guide to clean a non HP printer or a HP printer that does not use 564/920 ink, you are going to have to adapt the disassembly level/head removal to your printer, which you can probably find out how to on YouTube, or tinkering with the printer. '''If you are stupid enough to use these steps to work on a NON HP printer, or one that doesn't use the 564/920 ink cartridges orcartridge and break the machine, I don't want to hear it-it's on you.''' Got it? Good. On a different brand printerEpson, readyou will literally destroy the manual orhead removing it 9 times out of 10. It's better to find a online tutorialway to find out how to removeforce the water thru the printhead firstwithout disassembly from that side of the fence.
Epson owners: Boil your water and lay a napkin in the printer, then get a needleless syringe and get some vinyl tubing to clean them out-you need that to cover the print nozzle.

For HP ePrint enabled printer owners:
The method for printhead removal should be the same on Web Connected 564 printers too, but double check the mechanism to be sure. The only other thing to note is older cartridges will not work on web connected printers-you '''must''' use the updated cartridges since the programming on the chips is different, and the firmware blocks out the older cartridges. You actually can transfer the 564SETUP chips to bypass this, but you will voiddo this at the risk of the warranty if the printer craps out, since this isyou are technically amodifying the ink cartridge modificationif you have known good, previous generation HP ink. ChipI should also warn chip transfer is''can be''' extremely riskydifficult the first time it's attempted too, since the likelihood of busting the chip is high if you have never done it. It's dobable, due to the sunk in design HP uses for these inks to prevent but watch thatchip removal.so it doesn't break! Practice on BAD cartridges BEFORE transferring the GOOD chip!
Here is some more information on [http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02534494&cc=us&dlc=en&lc=en|compatibility with newer printers] and [http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02435884&lc=en&cc=us&dlc=en|identifying old generation ink cartridges] to refer to. If the cartridges do not match what HP says for the updated chips, it will not work in the e-print printers.
Note on HP 920 printers: HP no longer makes printers with the 920 print cartridge, but this guide will be useful to people with these printers who have them, but don't assume the bypass proposed here will work. Also, as I am the author and being I wrote this back in 2010 and just started to clean this guide up '''I do not have plans to source out a HP 920 printer anytime soon.''' If you want to write a guide for the 920 printers and beat me to getting one, feel free to use the printhead removal instructions, since I know these printers to beprintheads remove the same, but don't use these pictures(or bypass) since this is not a HP 920 printer. The iFixit community will have to find a bypass for 920 printers. I am not going to help, andbecause I don't want another printer floating around here I will help if I have timeno use for. If you want to try the HP 564 bypass on 920 printers, do so knowing it probably won't work(though I kind of expect it to.)
You can also try and bypass the initialization of the printhead on non-HP printers and other HP printersa modern Web Connected printer, but I will not guarantee the outcome for these printers-I only guarantee this method on the Photosmart c309g and '''some''' similarly aged printers with the 564 cartridgescartridge since I know it to work on printers from this era for sure-HP's Web Connected printers may have protections in place to prevent this, even if bypassed correctly-you can try, but it may not work since HP updates the firmware on these printers and requires the firmware updates toon a somewhat regular basis. The other problem is if you use theweb apps Web Apps on them, you will likely be forced to accept these updates. ''If'Also, be warned if the ink purge bypass is not done EXACTLY as written, it will not work!'' I have changed everything about this guide since this is originally from 2010 and things have changed a '''lot''' in 4 years, and wrote this at 16. I decided to correct this guide at 18, since I have a problem with Internet Connected printers-how I see it is I do not need my printer using 2 addresses to run on the network, or even 3 if ePrint doesn't run on the Wireless Print Server portion and is a dedicated connection. I turn it off anyway, so why even have it?'
.

I would also like to mention as the original author this will '''not''' unclog every case of clogged printheads-if this doesn't work and the ink is confirmed good the printhead is damaged and you will need to replace the printhead. You can also use the printhead removal steps to replace yourthe printhead.
