"Print head missing" after replacing the printhead.

I was getting a print head error after buying brand new cartridges. I went down the route of reseating the print head, then soaking it over night in an alcohol solution, letting it dry for several hours, verifying it didn't have any moisture and reinstalling it. Still same error. After resetting the firmware to factory defaults and going through the initial setup, such as language, I am now getting "Print Head missing." I reseated it, nothing. I purchased a new/refurbished print head, and get the same exact thing. I've also tried gently rubbing the contacts behind the print head with alcohol q-tip swab, and no good. Only thing I'm thinking at this point is to tear it down and reseat all of the ribbon cables and hope one of the main boards isn't bad. After spending $75 on original HP ink, then another $35 on a print head with refilled ink, it's making me to never want an ink jet again as I have an extra $110 of junk ink laying around that I can't use unless I but an outdated printer.

Did you wipe the contacts on the printer side where the print head caddy would touch the printer?

HP usually charges $75 w/ SETUP ink, so that sounds like you bought a used printhead that was cleaned. While these heads may end up working, I don't like getting the bare head from sites like eBay. The printers are sold at a loss and in many cases, a new printhead is as much as an entire printer (+/- a reasonable price differential) so nobody replaces them since it may not fix the issue and there's no refunds on parts as it's usually a one way transaction. What you end up with is a market with used printheads that may or may not work. You are essentially playing Russian roulette with your money with used ones.

My money is on a bad print mech or CMOS battery. More then likely what happened is the CR2032 in the printer died and when you unplugged it to preserve the calibration, you inadvertently erased it. That being said I'd also suspect the board in general. The first thing I'd do is get that printhead replaced and try again. If that doesn't work, check the voltage of the CMOS battery; the board will need to come out and it requires a complete disassembly. If the battery is within ~2.8-3V it's fine but if it's lower then that I'd just replace it.

If that doesn't sort the problem out, it's a board or print mech failure. At that point, the printer is dead. As to what to do with the ink... Your call here but I'd try and return it if you can. If not, sell the rest if you didn't open it to recoup the loss.

This is why I advise replacing the whole printer in my guide, at least as a general rule since printers are sold at a loss. That being said I do replace the heads but I don't buy them; I usually salvage them from high page count or partially dead printers that I verified are good. The problem is the way I do it isn't practical unless you regularly get them for free and you can identify if the printhead is recoverable. Even then I prefer to save the one it came with, since printhead prep wastes 1/4 of the ink in the standard cartridges.

@nick I do much printer maintenance, and while replacing the whole printer makes sense for a $150 or less printer, this doesn't make sense for a $400+ printer such as the C309g. I've purchased plenty of manufacturer refurbished printer heads for HP printers from ebay at $40 or less for a retail $80 printhead with no issues.

See this link. It makes no sense to replace the whole printer when a printer head for this model is a single piece of plastic which is designed to be replaced.

These printers were cheap back in the day, just like every other inkjet printer. They are usually eWaste when they die. That being said I understand what you're saying about the printhead but I disagree with you on the value aspect when compared to the price of a new printer. It's also a generalized recommendation under the presumption that the printer was cheap when it was new.

Here is a page with the 2010 price: https://web.archive.org/web/201010081508...

@nick Original CNET review says $300 AUD in 2009. With historical exchange rates + tax, that is still about $300 USD.

While my argument on repairing it stands and I'm drawing the line past a $5 CMOS battery, I've revised the answer slightly to give the OP to some pointers on what may be worth trying.

@nick some equipment, like $15k doctor's tool such as an EEG my friend has cannot use a newer operating system than Windows 2000. He cannot afford the latest version which now costs $24k. No new printers can support Windows 2000, and he cannot change the computer as it is calibrated and certified medical equipment. Sometimes you really have to repair an old printer.
