i remember having something similar in the navy for fire fighting crews,and those cartridges get fucking HOT.that was 30 years ago though,i am sure the technology is far better nowadays.

New printers now often contain half full ink cartridges to avoid people buying new printers instead of cartridges.

For us interested in photo quality print: Large, expensive ink jet printers are often much cheaper per page than cheaper printers - and you often save the extra cost of the bigger, better printer after a couple of ink refills.

Well, honestly, I have yet to run out of toner, I was just being sarcastic.

I also 100% promote lasers over inkjets. When you run out of toner, the cartridge is pretty much empty. Also, if you're like me and print something once every 2 or 3 blue moons, toner is already dry, and stays completely useful 10x longer than ink.

I have a Samsung full colour laser printer.

I bought it brand new for less than the cost of replacement cartridges.

When it's final out of toner, I will throw the printer away and buy a new one.

It's just cheaper that way.

Your video, “Empty” Epson ink cartridges are still 20 percent full, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

Well. It's on purpose, obviously. Money is made on service and ink cartridges, far moreso than the printer sales!

I have no evidence, but I submit this video as people's exhibit A.

You can dose yourself down just by the solution you use. Even with off-the-shelf cartridges.

Lol not everyone had a sound card back then. Saddly it does no look like anyone as done a video of the days of audio over the pc speaker. I mean it was mostly un exciting, but there were a few example of great engineering feets. Some games that used MOD music (usually if it was done on AMIGA first and ported to pc) mixed the digital music into a mono WAV form and used the interrupt heavy digital audio output over pc speaker method. I owned a game that I can no longer remember that had a custom audio track that was fairly simular, and rapidly alternated between 2-3 instrument tracks for a fairly convincing melodic background music without the huge performance overhead trying to do MOD music over pc speaker had.

If it isn't obvious, I was a huge audio fanboi back then. Started with my C64 and SID music (I even owned the external SID cartridge for 6 track stereo music), and when i got my first PC (486) I picked up a 2x cdrom and sound blaster PRO (had to have dat stereo sound) for my birthday.

I wonder how long the seal between the barrel and drum holds.
With your normal household revolver the gasses escaping from there are quite dangerous, scaled up to a shotgun shell wouldn't want that so close to my face.
That being said I undertand the burn velocity of the propellant is probably lower than that of a revolver cartridge, but is it significant?
Any Videosift Munitions/Firearms expert wanna school me a bit on that?

After reading a bit more, it's clear what is going on. This is a striker fire mechanism; the firing pin is not driven by a hammer, but by a spring, in-line with the cartridge. This mechanism is used in many weapons, but it does have a couple possible failure points.

If the spring is missing or is the incorrect tension, the striker may ride forward into the breech where the cartridge is at and when a round is loaded, may cause a slam-fire. This is mostly seen in semi-auto rifles or military ones.

The second failure point, and the one that seems to be the most likely here, is a faulty trigger disconnect. This feature is supposed to disconnect the trigger action from the striker assembly to prevent this exact thing from happening. I would gather that it's not working correctly.

Funny side note, up to 1975 some Winchester pump shotguns were designed this way on purpose. Called Trench or Riot guns, they were intended to be used this way to clear areas of hostiles rapidly by simply holding the trigger down and pumping the action as fast as possible. In fact, the model 1897 Trench gun was so feared by the German soldiers in WW1 that Germany threatened severe punishments to any American soldier captured with a shotgun.

Hey! I see a comment from 9 months ago so I figure I'm not too late! Love the old cartridges. My brother and I were always SEGA men ourselves. I have two SEGA Saturn games that I might offload through eBay for a pretty penny. One is Dragonforce worth roughly $150 now and the other is Panzer Dragoon Saga worth roughly $300 or so. These games gave me so much joy and entertainment as a kid and it makes me happy to see that other appreciate them as much to this day! Hope your old games found good homes and are loved.

The tank mods are added by retailers and print shops. You're right about how the system works -- the lines run from the big tanks and are inserted through a hole drilled into the carts small reservoir.

One issue with that is that most cartridges have a software page count that is used to tell you that the ink is running low / empty after a certain number of prints. So, along with the tank install, most shops will put in an aftermarket chip or PCB that resets or bypasses that counter.

For the other question, I think that Thailand still relies on printed documents more than in the US, but it is going down. I undoubtedly have a somewhat skewed opinion on things since I am a teacher, though. I teach 18 different classes of roughly 40 kids once a week, with a worksheet or some other printout being used nearly every week -- so I probably burn 700+ pages each week through my school's copy machines. Then I teach smaller private classes at home, with maybe 100 or so pages a week on my own printer(s). I have one inkjet with those tanks installed, 2 mono lasers, and 1 color laser... So yeah, I probably am a much heavier user of printed stuff than your average person.

Who is adding the tanks to the printer? The people selling them to retailers, the retailer, or is it a DIY? I'm guessing the lines connect to the cartridges in the printer and just kind of keep them full? Or do they tap directly into where the print cartridge connect to the heads? I think it's cool. Thanks for sharing.

Another question is do people in Thailand have a need for lots of printing? I'm in the U.S. and would say that personally, my printing needs have gone down 90% say over the last 10 years. At home, I print maybe 5 pages a month.

I think I'd have to see it in actual printed form to judge the readability accurately.

BUT, in terms of readability on a display, like the 40" 1920x1080 LCD I'm watching on ... it is quite poor in my opinion. I have a feeling that it would work much better in ink on paper.

33% ink savings sounds pretty good, assuming that the readability on paper is better than a display. That being said, encouraging printer manufacturers to have a more sane approach to refillable ink/toner reservoirs would have a better/bigger impact.

Here in Thailand, where respect for patents / IP is low, (SE Asia is notorious for fake manufactured goods, pirated "soft" media, and hardware hacks / bypasses) I'd guess that around 90% of inkjet printers sold have a tank system glued onto the side with ink lines running into the cartridges from big CYMK reservoirs. I never buy new cartridges unless the print head gets damaged/worn out -- instead, I just buy cheap LARGE bottles of the different ink colors and refill the reservoirs. (Image link of such a setup HERE)

That kind of mod would be a gray or black-market item in the West, but here the laissez-faire attitude about such things has some positive effects. At least, for a consumer (like me), or someone concerned about the environmental impact of all the waste packaging for ink carts (like the dude in this video).
