Question on how to handle a poorly written 2010 guide?

Hello iFixit, I have taken a look at my 2010 Photosmart Premium printhead clenaing guide, which can be found here, I have taken a look back 4 years later on it and I have seen just how horrible it is compared to my new guides I have made, so I have considered trying to hunt one of these units down from someone who is dumping it, and I will redo it, if I can get my hands on a good, used one similar or the same as I had in the 2010 guide

I no longer have this printer because the printhead failed some years back and now run a B/W Laser printer and would never go back to a Inkjet printer as a main machine, but despite this because I did get a better camera, repainted the room from the nasty yellow paint and have a better desk, and my guides have improved in general I do feel inclined to either fix this mess of a guide, or redo it, get that one approved and have admin delete the 2010 guide when I get a new one finished and approve a new one

Right now I would like to leave the 2010 blunder guide be as it still helps people but at the same time I do want to find this printer a second time, and make it better then it was in 2010

Think of it as HP printhead flush 2.0 if you will

Before I decide what to do with this one while I find one of these units(or a very similar one) I can snag for nothing because of empty ink, or a clogged head I am open to suggestions on how to handle it until this day comes

So what seems like a better solution? Find one and redo this, get the new one approved and have the old messy one deleted by admin or just change everything about this one-right now the best I can do to correct it is put warning where I screwed up, and tell people what to do and what not to do

First round of edits have been done-this round fixed the step text, replaced 3 pictures and added a step to heat the water up, as I found out works wonders on clogged printheads a few years ago, wanted to implement while I had this one and I forgot, but now got around to adding it in

I would do something with Step 3, I am kind of reluctant to fixing it without a similar(or identical) printer right now-maybe I can get away with it and maybe I can't but I may try and do it-but keep the original picture just in case

I just talked to one of the neighbors I know-he's having a garage cleanup for a few days, and soon a yardsale-if there's a similar printer to my 2010 guide that works out well, I can pretty much finish the edits entirely-the focus right now is to deal with the sloppy writing, then the remaining pictures

I am also going to focus on making it less of a "generic" repair guide, and tier it more for the Photosmart Premium c309g

Also, if I put printhead instead of print head as I have to correct now, printhead is the technically correct term for this despite it not being liked by spellcheck in browsers

Before I went all in and commited this to the repair guide, I decided to demo it on scrap ink and demo the results I got with this method compared to my 2010 method

I put this scrap ink cart that has a serious clog into hot water from the Keurig, and the second it touched water, it CLEARED out like CRAZY-Here is some pics of how effective this is

There has been more changes to this guide as of late-I changed how I approached explaining the bypass for the C309g to one step to make this easier, added steps to make adding assistance from rubbing alcohol possible, test print suggestions and test pages to assist with this, along with 4 and 5 nozzle test print PDF files

The reason I rewrote this guide is simple-I do not like the new generation of Web Connected printers, which require FW updates constantly, they block out previous generation ink(2011 and 2012 inks, some 2013) and will probably reject old generation printheads too-they are not something I will support

I have a feeling changing the chip was a stunt to screw over remanufacturers, and force people to replace perfectly good ink, since the expiring ink tactic doesn't work more often then not and was removed from modern HP inks

The older ones take advantage of OLDER parts, you can use OLD and NEW gen ink carts, and they don't require constant FW updates-they may not use NEWER printheads, and I do not have a older head and Web Connected printer to check

I have rewrote most of the intro description, but please know now I will not be experimenting with the HP 920 printers at this time, but I will invite the iFixit community to do it if you want :-)

HP no longer makes printers with the 920 cartridge, but this guide could be useful to people with these printers too that still have them, but do not assume the 564 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 do not have plans to get 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 room. 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, just don't use these pictures since this is a Photosmart 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.

Yep.... I do not have plans to find a HP 920 OfficeJet since they're likely nastier with ink usage then a tamed 564 printer(though they may be better), but I will work with you guys as I can to get around those, too if needed. 5 standby printers is probably a stretch, but I think it drives my point home on the pile thing-I do not want to pile 920 machines to get around the head removal detection-isn't worth it
