Refilling HP ink carts
Is there a way tio refill HP Inkjet carts, like the HP 45? Seems I used to
do that before lasers. I was given two HPs and both seem to have dry or spilled carts. Thought I'd like to try the black on one for starters for text. Suggestions? TIA -- I love a good meal! That's why I don't cook. |

The customer can then buy three different capacities of carts. There is room in the cart, for 500 sheets, 1000 sheets, 1500 sheets worth of printing. They put the 500 sheet version in the printer when it's new. They did this, because some people were buying inkjet printers, and throwing in the trash when the 1500 sheet cartridge was exhausted. By putting a low-value "teaser" in the printer, this prevents immediate printer disposal. And increases the chances a customer will pay $50 for the printer, and $50 for a change of cartridges. ******* There are some Epson printers with "tanks". No chip there. Such a solution is suited to office usage.

The "bet" could be relatively expensive if you just drive to Staples. Not all brands are chipped. HP is probably a chipper, but try and track down verification for the HP 45 cart. Ink carts (not the tank version), cannot actually be pumped dry. There is a problem with vacuum building up in the cart. The cart has no "pressure vent". If it had a vent, the cart would dry out. Carts use a patented "sponge" material, which handles the ink cart from say, 3/4 full to 1/4 full. If the cart is actually under vacuum, the 2 picoliter pumps on the head, cannot overcome the vacuum when printing. The sponge expands to fill the void in the cart, as the ink drains.

The manufacturer who is wasting money on these chips, you can be assured they've used reasonable precautions to prevent tampering. There was a piece of software that would, with some models, reset the chips, with other models, take a snapshot and "freeze" the reading (i. e. you had to use it with some working cartridges before they ran out). I think the software was created by a Russian. I haven't looked for it for years; even possession of it if you're in the USA is probably an offence under DMCA (abused as often as the Patriot act). It (the software) probably doesn't work under later versions of Windows anyway, which "just happen" to break it. (I suspect it won't work with more recent printer models anyway.) Third party ink suppliers have tried various ways around this. It's gone to court at least once (counterfeit chip). Did that use DMCA, or copyright legislation? [] There are some Epson printers with "tanks". No chip there. Such a solution is suited to office usage. You can also get CISSs, continuous ink supply systems: https://www.cityinkexpress.co.uk/ is one such supplier in the UK, but I'm guessing they exist in the USA and elsewhere too. (I've just checked, and that website still works, and mentions Brother, Canon, Epson, and HP on the home page.) These basically use dummy cartridges, connected to ink bottles via fine pipes. I would be interested to know how they work with the "chip" type printers; they certainly offer such systems for such printers. And if you look around, some manufacturer may attempt to use "chipless" as a marketing feature. (-: [] Not all brands are chipped. HP is probably a chipper, but try and track down verification for the HP 45 cart. And not all models from those brands are - though the older ones that aren't, you probably can't get drivers for for modern OSs. (And they may not use ports that modern PCs have.) Ink carts (not the tank version), cannot actually be pumped dry. There is a problem with vacuum building up in the cart. The cart has no "pressure vent". If it had a vent, the cart would dry out. Carts use a patented "sponge" material, which handles the ink cart from say, 3/4 full to 1/4 full. If the cart is actually under vacuum, the 2 picoliter pumps on the head, cannot overcome the vacuum when printing. The sponge expands to fill the void in the cart, as the ink drains. Thanks, good explanation. I didn't know they couldn't be emptied, other than for concerns about ink drying in and thus clogging the heads. (I think only EPSON use actual pumps, heads with piezoelectric material; I think the rest use boiling ink to propel it. Though I suppose you could still argue that that's a pump.) Note that there's also a drain/waste ink tank in (some models of) the printer itself, which collects when the cartridge is parked and wipes its nose; when this is full (the printer has a counter), the printer will also stop, to prevent an overfull such tank causing the cartridge to smudge and generally make a mess. Some software (I think it was the same one as above, that did things with the chip counters) could reset this counter; however, this doesn't of course actually empty the tank, so if you do keep doing it eventually things will start to smudge, not to mention the inside of your printer getting into a terrible mess. Good luck in your research, Paul I do find it depressing that it has been made legally possible to technologically prevent (or at least make it very difficult) to refill inkjet cartridges, and that legislation which was not intended for this can be invoked against anyone who tries. (I wouldn't object to just the voiding of the guarantee if non-OEM ink was used; that does seem fair.) -- J. P. Gilliver.

Good luck in your research, Paul I remember reading a while ago that you needed 3 HP cartridges. When a cartridge reported it was empty, the printer remembered that cartridge said it was empty. Putting ink the cartridge didn't change the fingerprint of that cartridge when reinserted into the printer. You had to use a different cartridge (different fingerprint). After the 2nd cartridge ran out of ink, you'd think you could put ink in the 1st cartridge and go. Nope, there's a history which appears to be the last 2 cartridge fingerprints. So you needed a 3rd cartridge. When the 3rd ran empty then you could go back to the 1st cartridge. You needed 3 cartridges to get past the printer remembering the prior 2. I don't know if this trick still works, plus the OP would have to buy 2 more cartridges which obviates him trying to reuse just one cartridge (with lower quality ink which usually results in poor output and possibly soiling the rollers). The other way of reusing the same cartridge requires resetting it. I don't remember the trick but it had to do with using cellophane tape to cover some contacts, insert the cartridge, remove it, remove the tape, and then reuse that cartridge (but maybe you had to do this twice to get past the 2-cartridge history in the printer). https://www.bchtechnologies.com/blog...cartridge-chip http://www.inkbank.com.au/category104_1.htm "Most newish HP genuine cartridges (with print-head) can be refilled and work without resetting chips." So HP got sued, lost, and had to change the code in their cartridge chips. You still have to figure out how to reset the printer to remove its status on that cartridge (from empty before to unknown now; i.e., restart the page counter in the printer). I wish I could remember the name but it's been too long since I last purchased from them, and eBay only goes back 2 years in purchase history. Many sellers advertising refilled cartridges are doing just that: reusing old cartridges, putting new ink in them, and dumping them on consumers as new cartridges. The place I referred to had their own manufacturing facility, their own web site, an actual postal address and phone number, and a plant to fill the new cartridges. They bought new cartridges in bulk (aka virgin cartridges) and filled them with their ink (which was okay but still not quite as good as HP's ink - ink formulae are closely held trade secrets). In fact, if you go to eBay, you can find auctions where all they sell are new (and empty) cartridges: search on "virgin printer cartridge". That way, you get a new cartridge instead of someone's problem passed onto you through a mere refiller seller. I use up one black and one color cartridge in just over a year. I do little printing. Even if I need to prove something, communication is electronic so a file with a sales receipt is sufficient. I use the scanner a lot more than the printer. For me, having to mess about with sub-quality inks is not worth the loss in print quality or messing up my printer because the ink didn't dry before the paper hit the rollers. I've tried several pre-refilled cartridges but reliability suffered as did ink quality. If I were to do a huge volume of printing, I certainly would NOT use an inkjet printer but get a laser printer. Inkjets are cheaper because they are considered "ink delivery systems". Their purpose is to sell ink, not to generate [much] profit on the printers alone. Laser printers cost more up front but their cost per page is a lot lower. For inkjets, the average is 20 cents per page (unless you only print in black which lowers to 8 cents per page - but who gets an inkjet to only print in black?). Black-only lasers are 6 cents per page. Plus the print quality is much sharper and much more permanent for lasers (bonded print) than inkjets (wetted print). There are color lasers but I don't know if the color toner ever dries out. While inside the moisture proof seals, toner seems to for 8-12 years. Once out of the bag, they typically get replaced in 18-24 months (unless used up by then). Yes, it was possible to refill laser toners. What a farking mess! Some oldies had a port into which you used a bottle of toner. Problem was that once opened the bottle of toner started to degrade due to humidity (in the air that got into the bottle or leaked past the no longer present moisture seal). Determine how long your toner or inkjet cartridge lasts (how many sheets of paper over 2 years). Take the cost of an OEM/manufacture-brand toner or cartridge and figure out the cost per sheet. Reperform that calculation using a refilled toner. Do the same for inkjet cartridges. Bet the cost per page isn't sufficient for you to bother with personal print volume at home. Only makes sense in a business environment where they're printing multiple thousands of pages per year. |

But you can probably figure out why they use a steel ball (to prevent refilling). That cartridge design might be around 16 years old. Paul The sale you linked to is NOT for an empty and never filled (virgin) inkjet cartridge set. Look at the "Cartridge's Status" in the description which says "Full". Virgin cartridges are never full because they are sold empty. YOU fill a virgin cartridge with your choice of ink. Since the description says "re-manufactured", that means these are used cartridges that got refilled. At Walmart, the HP 45 black cartridge (new) sells for $54. The HP78 color cartridge (new) sells for $64. A combo pack (new cartridges) sells for $115. AliExpress is selling a used (not virgin) HP 45 & 78 combo cartridge set for $45 that they claim has been filled (status = full) but no clue whose ink is inside, and for a lot less than just a new HP 45 alone. I found one eBay seller claiming to sell a virgin HP 45 inkjet cartridge. He hasn't a clue that "virgin" means NEVER EVER filled with ink. Instead the seller uses "virgin" to mean "unused and filled". It is tough to find someone that will sell 1 or a dozen virgin cartridges. The sellers market their wares to plants that use the cartridges to build in volume. The cartridge manufacturers will give you quote but likely the minimum lot size is 1000 cartridges. You have to find someone that sells you their manufactured (not re-manufactured) cartridges where they bought virgin cartridges and use a decent ink. They'll sell you a full cartridge that has never been used (but no longer virgin after they added their ink) that doesn't have the "HP" brand, so they sell at a much cheaper price than whomever manufacturers the cartridges that get an "HP" sticker. You don't want re-manufactured, refurbished, used, or pre-owned cartridges that got some non-descript ink pumped into them. Hell, you can do that job yourself for a one-off production. I was not suggesting to go out to find virgin cartridges for yourself to fill yourself unless you're looking to start a business and buy in volume from the cartridge manufactures to get virgin cartridges. I was suggesting to find a cartridge seller who says they use virgin cartridges (not re-manufactured, not refurbished, not used, and not pre-owned) and describe what ink they're putting into those virgin cartridges (which are no longer virgin cartridges when they sell you a filled cartridge). Note that Ali Express is not very accurate in their product descriptions. They do sell virgin cartridges but some are still listed as re-manufactured despite they are actually virgin cartridges. Search on "empty virgin hp 45 ink cartridge". I found them selling HP 45 cartridges for $12-$16 (depends on volume) for each piece from one manufacturer but the minimum order is 50 pieces. They also sell from another cartridge manufacturer the HP 45 cartridges for only $2.10-$6.90 apiece but again for a minimum order of 50 pieces. What I did back several years ago was find someone who used virgin cartridges, had a descent description of their ink, a guarantee from the factory (who was also the seller), who sold under their brand instead of "HP". HP doesn't manufacturer cartridges. They contract one of the cartridge manufacturers or ink fill plants to stick "HP" labels on that manufacturer's product. Since ink recipes are secret, I doubt they could use HP's formula in a non-OEM branded cartridge. It's like getting RAM modules from Corsair: there's a sticker that says "Corsair" but Corsair doesn't manufacture anything. The spec it out and contract someone else to build the product, or relabel a product (stickers are used to cover manufacturer printing) that meets their specs. That contracted manufacturer makes the same product for many different brands, and sometimes under their own brand. |
