With the assistance of the PCHelpForum, I recently set up an old printer, Samsung SCX-4623FW. Now that the printer is up and running again, I decided to look up information on the printer cartridges. There are two types of printer cartridges for this model of printer: A low yield cartridge (model #MLT-D105S) which can print upwards of 1500 pages and a high yield cartridge (model # MLT-D105L) yielding 2500 pages. The cost of these printer cartridges are exorbitant (both over $100.00 CAD (Canadian) and refurbished cartridges, although cheap come with a cost: error messages and yielding much lower printouts than advertised.

With the advent of the internet and more and more information posted online, I discovered that it is possible to refill these cartridges myself. The problem is that there is a chip which detects when the low and empty. Luckily this model of printer will still allow me to print documents but it gives me a warning on the panel which flashes red (and is annoying).

I have found the following videos with respect to refilling the printer cartridges:
The first video is by a fellow who is in Britain and simply refills the cartridge and re-installs a new chip. He does not discuss where he gets the replacement cartridge chips:

The second video is by a fellow who apparently is in Italy and provides detailed instructions of how to properly clean and refill the printer cartridge:

The third (and a very interesting) video at that is by a fellow in Romania who reflashes a similar model of printer cartridge (MLT-D1052) by simply connecting the computer to the printer and reflashing the chip:

When I first bought the printer, this information was not readily available. The purpose of this post is to find out if anyone has experience refilling printer cartridges and whether a code could be developed to reflash the printer cartridge chip? Or where I could procure replacement chips if i am refilling the cartridges myself?
 
Used to refill cartridges years ago but don`t bother any more, you can get repurposed cartridges real cheap and even the HP ones that I use are not expensive, short version, not worth the hassle, you can get printers with cartridges cheap enough nowadays as well.
 
Hi phillpower2,
I think that the hurdle is cost of replacing the printer's chip. But if it's possible to flash the chip, then I believe that the cost to refill the cartridge would be cheaper than buying repurposed cartridges. There are two things that worry me about repurposed cartridges:
1. the fit and finish once the cartridge is put back together and the wear and tear it causes on the machine as a result;
2. the fact that the predominant opinion of consumers that the repurposed cartridges do not yield what the original printer cartridge should print.

For these two reasons, I thought I would look into trying to refill the cartridge myself. The overarching problem for me is replacing/reflashing the chip.
 
If wanting to fill your own ink cartridges ink tanks are the way to go, see article here

No worry about sourcing and/or paying for reflashing info + you don`t get any software conflicts or false/missing ink levels.

Hi phillpower2,
I wouldn't mind buying a new printer. But one of the reasons I decided to try and resurrect the old Samsung SCX-4623FW printer was as a result of walking into a local Best Buy store here in Toronto and discovering that although the model is now discontinued, similar printers remain on the market (most notably the Brother DCPL/MCPL series of printers). I forgot which model the store had on display, but fiddling with the button layout and checking the fit and finish of the machine, the machine I owned felt sturdier and possessed all functions of this new machine.

Unlike other printers which have a chip built into the cartridge, if the machine reads on the display that the cartridge needs to be refilled, the Samsung SCX-4623FW printer still lets me override the warning and continue to print. The only annoying thing is that there is a red led light that blinks rather than a solid green light. The other reason is that the machine is still perfectly functioning even after installing it on newer laptops. In this day and age, things are discarded to the trash heap all too readily for the latest and greatest new device.

If overriding the chip is not a possibility at this time, I simply need to source where to buy the refill from. Would you be able to assist me in a reliable company who could sell the refill? I am located in Canada so I have no problem either buying it from another province or from the US (if the price is reasonable).
 
Hello Metastasis,

Sad fact is that older = of better quality as most things are mass produced on the cheap by you know who and quality suffers as a consequence, I`m still using a ten year old wireless HP printer and the only bug bear that I have with it is that the HP Solution Centre (Ink levels etc) no longer works as it relied on Flashplayer which is no longer supported by Windows 10, 11 and possibly 8.1.

I`m in the UK so not best placed for suggesting cartridge providers but you are sure to have plenty where you are, examples of what we have here are Cartridge World & Stinkyink

Hi phillpower2,
I'll look around and see what I can find in my area with respect to refilled cartridge providers.

It's good to know that you are using a older printer as well. I have another older printer that is semi-operational and probably a little older than yours. What is interesting is that the software still works on WIndows 8.1/10 machines. It's in the best interest of the manufacturer to support these older machines as they can still sell cartridges to the consumer.

The printer I own is a "HP LaserJet M1522nf Multifunction Printer" which is an excellent mid-range printer for it's time. The issue: when the printer warms up, after only a few minutes it will get stuck. If you try to restart the printer soon after, it will fail to initialize. The issue: bad soldiering on the board itself! That's it!

Someone posted a how to video of how to reflow the solder on the board by baking it in the oven (video here:

). I am not certain if I want to take such a drastic measure especially as the user mentioned that the issue popped up once again. I may opt to have it re-soldered instead by someone who knows what they are doing.
 
So with respect to the issue with the formatter board, I do not have the technical skills or experience to check and re-solder the board. Could you suggest who I should approach with respect to re-soldering the board? The HP LaserJet M1522nf Multifunction Printer probably has printed less than 3000 pages (if that) and probably still has years left. As mentioned before, when you plug it into a modern day computer it is able to install the necessary drivers without any problem and it still works (albeit a short period of time). The build quality is definitely better than the Samsung printer discussed in my other thread.
 
For that they may probably cost you to have done you could almost and or fully pay for a cartage.

Would see about computer shops and or electronic shops that are certified. Anyone can they they can do it then you may end up with a nice door stop.
