Help needed with HP 45 Inkjet Cartridge

[yashved]

I have tried to refill a HP 45 Inkjet Cartridge. To the best of my knowledge, I have followed most of instructions perfectly. However, I am doing this for the first time... so I can be going wrong somewhere.....

The instructions included removing the black round sticker and then pushing the button inside, followed by injecting the ink inside. After injecting about 5-7 ml of ink inside, I sealed the mouth of it (i.e. the hole in which I injected ink) with the same round black sticker and also added some cello tape to it.... I have read about sealing the hole with a screw, but I wasnt sure how.....

So after I turned the cartridge upside down, it is leaking continuously... not from the header but from the hole (the hole in which I injected the ink....)

What shall I do next? I surely cannot fit a leaking cartridge into printer.....

Shall I remove the stickers and cello tape and seal it with something else such as a screw? Please help as early as possible since I am not sure if ink will dry away like this....

Thanks in advance

The 45 uses if I remember correctly 40+ml of ink. ( Yes, those were the days when a cartridge was a real cartridge) . You will need to refill it till it reaches the top. SQUEEZE the sides. While keeping it sqeezed you will need to reseal the hole PERFECTLY. NO LEAKS. Then turn the cartridge over and release the pressure. If it leaks, let it. Just absorb it till it stops and then place in printer. It is best if you use a small clamp to keep the pressure on. The cartridge has a bladder with a spring that needs to set up a vacuum to prevent the ink from leaking out and thus the reason for the squeeze.

Yes those HP 45 cartridges were great: 42 ml total capacity and actually I have a special mouth refiller to refill this cartridge right trough the ink nozzles without opening the cartridge at all. It costs only a few euros/dollars. Just push the ink with a syringe through the mout filler and put it upside with the nozzles pointing upwards and then squeeze the side walls together and pull a few ml back into the syringe and releas the side walls.

The mouth refiller actually cleans your (blocked) nozzles each time you refill.

Yashved whose ink refill kit are you using?

You just need a rubber plug to replace the steel ball you pushed into the ink bladder.

Mikling the 45 cartridge takes a 5/32 rubber plug will your silicone plugs work in the HP45.?

Don't know if they will. I never tried but I haven't touched a 45 for a while.

My old HP 712 gave out after many years of service. 45 cartridge was great with a huge capacity (about 40 ml). I initially sealed the hole with hot glue, then later used a rubber plug. I also filled through the head with the use of a cartridge "bleeder" (don't know the offical name), and worked fine. I miss the cartridge capacity when compared to newer HP's (5 ml and even less!!!).

I have this OfficeMate Refill Kit.... But it contains only ink bottles and that syringe.... there r no rubber plugs or any such other covering materials....

I dont have that rubber plug.... Is there any substitute for it?

If not, is that a special rubber plug? where will I find the rubber plug?

I have tried adhesive tapes, but after sometime, it started leaking again.....

The 45 uses if I remember correctly 40+ml of ink. ( Yes, those were the days when a cartridge was a real cartridge) . You will need to refill it till it reaches the top.

Is it so that 40+ ml (42 to be precise) is the required capacity or max capacity. I mean is it OK if I fill in 10ml only or shall I fill it completely?

Thanks!

If it is not complete, the required negative pressure is going to be hard to generate and you'd probably leak a lot of ink before it stabilizes.

I use this device to refill the HP 15 and 45 cartridges:

This airpuller is also used to pull air out of the cartridge to creat a vacuum. Ink is pushed right through the nozzles and also cleans them if blocked. Very effective and no drilling, glue, plugs. Very easy and neat.

I own a Refilling shop in south India, Most of the cartridges can be Refilled with Latest Technology with the help of Machine.......that includes HP 45
