Introduction
Is your HP Photosmart C309g's printhead clogged, producing streaky output or not printing a certain color, even with new ink cartridges? This guide will teachshow you how to unclog the printhead on this printer.
The cleaning steps will work with other printers with in printer printheads that can be removed/replaced, but the printhead removal steps and the steps to bypass the printhead initialization are tied to this model and similarly aged 564/920 printers-if you use a HP printer that doesn't use the 564/920 ink cartridges or a different brand printer altogether, read the manual or find a online tutorial to find out how to remove the printhead first. The method for printhead removal should be the same on newer 564 printers, but double check to be sure.
HP no longer makes printers with the 920 print cartridge, but this guide couldmay be useful to people with these printers too that stillwho have them, but do notdon't assume the 564my bypass will work for you, as you may not have such an option as an OfficeJet owner. Also, as I am the author and wrote this back in 2010 and just got around to fixing this guide up '''I do not have plans to getsource out a printer with the HP 920 inks unless it's given to me. If I get one for free, then I will consider it since I do not want to have 5 printers in the corner of my roomprinter intentionally.''' 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 be the same, but don't use these pictures(or bypass) since this is not a PhotosmartHP 920 printer. The iFixit community will have to find a bypass that works every time, but I will be glad to help if you want :-). If you want to experiment with the HP 564 bypass, it's at your own risk(though I kind of expect it to work.)
You can also try and bypass the initialization of the printhead on non-HP printers and other non 564/920 ink HP printers, but I will not guarantee the outcome for these printers-I only guarantee this method on the c309g and similarly aged printers with 564/920 cartridges 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-you can try, but it may not work since HP updates the firmware on these printers and requires the firmware updates to use the web apps on the printers. '''If the ink purge bypass used here has to be done EXACTLY as written, or it will not work!'''. I changed everything about this guide since this is originally from 2010 and things have changed a '''lot''' in these 4 years, and originally wrote this at 15 or 16(though I suspect I did this at 15).
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, which is 50. You can use the printhead removal steps to replace your printhead.00 online last I checked, which is why this method exists.

Summary
Printhead clogged? Try this cleaning method. The goal is to clean the print head by soaking it in water. This method is not guaranteed to work, but did work for me.
