HP Patents Ink Cartridge Vending Machines

- By - Source : USPTO

HP is apparently thinking about a way to increase the number of locations where its customers could obtain new printer cartridges, give back old cartridges and refill their used cartridges.

A patent filing outlines the idea of ink cartridge vending machines. According to HP, a vending machine could be an alternative to expensive cartridges that are ordered online. It could also make the refill process of a cartridge much more convenient (and, of course, makes sure that HP gets the sale and not a third-party ink provider). HP envisions those boxes as one-stop solutions for ink cartridge needs.

It is unclear how serious HP is about this concept and whether it is something could be used globally, given that HP engineers in Singapore filed for the patent back in June of 2010. However, we could easily imagine printer cartridge vending machines in locations at traditional shopping malls.

The invention is described as:

"vending machine [that] includes at least one cartridge receptacle for receiving an ink cartridge, a user interface, a display unit, a nozzle health check module, a printhead servicing module, an ink reservoir, an ink refilling unit, a compartment containing new ink cartridges, a compartment containing filled, second-hand ink cartridges, and a recycle compartment for receiving discarded ink cartridges." A customer would chose "the option of (a) refilling a used cartridge, (b) purchasing a filled cartridge, or (c) returning a used cartridge in exchange for a purchase rebate or a discount voucher."

Those returned cartridges would be internally recycled and prepped for the purchase by another customer, who may choose a second-hand cartridge over a new cartridge to save some money. HP did not comment on the patent filing, but it seems to a reasonable idea that may, at the very least, enter a field trial. Not only can HP increase its point-of-sale presence, but it can also defend itself against discount ink suppliers much more effectively.

These'll be big in Japan. I hear they have vending machines for just about anything.

I sure hope the actual patent is much, much less vague than that excerpt. Sounds to me like such a patent could possibly prevent other companies from developing the same type of technology on their own, rather than foster innovation like patents were originally supposed to.

I'm not sure if that's the case. If so, shame on HP. If not, then kudos. If it's cheaper to stop by the vending machine and refill the cartridge than buying the new one, then I expect this will see lots of business.

If you can live without color the HP LaserJet is the best bet. Reliable, fairly cost efficient and good quality.

We have a 10 year old LaserJet 1000 series and it is still printing just like new.

Personally I can't see myself using these vending machines when they come out. What happens if you lose money if the machine is faulty! I've had that happen to me plenty of times before using choc bar,etc vending machines. No way,Josey! I will not touch a single vending machine,I like the good old customer service idea of going into an office supply store & buying my ink cartridges...

The idea of ink cartrige vending machine is great, but it's to general imo to patent it..

Yeah, I don't think you should be given a patent for this one. It's like patenting a vending machine for candy. Patent the vending machine but what it dispenses IMHO is unpatentable in my mind. Because you can put anything in there.

Ok, so if I have one vending machine with new cartridges and used cartridges (pretty much ANY vending machine could do this), one vending machine that refills/tests cartridges (this might be new and novel, don't know), and one vending machine that recycles old cartridges, and I duct-tape them all together, would I be in violation of this patent? It's not really clear to me what HP is trying to patent. I would think a machine that automatically refills and tests cartridges would be pretty cool. I think slapping that machine into another machine that also sells new and used cartridges is in no way actually inventing anything, and I wouldn't think that warrants a patent.

This would have been like Eli Whitney inventing the cotton gin, but in his patent application, he throws in things like: "This invention will contain one device that separates cotton from the seed, then it will contain one storage bin for the discarded seeds, and one storage bin for the cotton, and it will have a set of wheels as to be mobile." When in reality, the only thing people care about is the gin itself.

That's exactly why they are doing it. I've already seen these machines set up by 3rd parties in grocery stores. Been there for years. This patent allows HP a cease & dissist injunction against those business without ever putting an HP machine in it's place.

It's not wonder HP is failing...

Soon ink will be obsolete, and they working on way to protect their cartridge business... rather than moving technology forward and away from pen and paper.

I'll have to agree with Wish I Was Wealthy and I will stay with normal walk in stores.

I am not so sure. I think that the existing machines would fall under "prior art". After all, they clearly existed before the HP patent.

Never buying an inkjet printer again...the ink is ridiculous.

I will stick with my Canon, I can still get compatible carts for less than £3 and they occasionally go on special offer for less than £1.

What's the point of using an ink printer with all its negatives (drying-out, smearing, ...) when one can buy a similar laser printer for cheap?
