How to open HP laser jet cartridge

Don't know if this will help but here it is anyway...

YOu use to see bits about refilling laser cartridges, in the early days of home laser printers. Don Lancaster wrote about it, and for all I know he may have the old article somewhere on his website,

But, and I realize it may depend on the cartridge, I remember his instructions being about drilling a hole, and then funnelling in new toner, rather than opening the whole thing.

It can get pretty messy if you have to open the whole thing.

If you want refilled cartridges, I just saw an eBay seller for $15.72 including shipping. Do you really want to mess with that stuff yourself? GG

| I'm breaking my head as how to open the toner cartridge of my HP | laser printer, which I'm willing to refill by myself. I can see the | lid at the left end, but can't remove the top cover completely so as | to pour the toner. It seems that I'm missing out some hidden screw. | Cartridge is C7115A taken out from a HP laser jet 1000 series printer.

The kits I've seen give you a soldering iron with a circular head to cut a hole in the cartridge, and a plug to fill the hole. And a book to tell you where to put the hole on each type of cartridge. And some toner, of course.

You burn a hole, fill it with toner, put the plug in.

It works pretty good, but it IS messy. Do it outside :)

Hopefully no hole is to be drilled out here, toner container is having a lid which can be removed easily.

Did you see the PDF I linked? If that's your cart then it should be exactly what you need. It is typical to need to punch/cut/drill/etc a new (one-cycle used) toner to refill it. A remanufacturered cart may have screws then added if the particular cart needs them after being disassembled. Depending on how wasteful the printer is (don't know about that model) it is a good idea to empty the recovered waste toner. Just be careful not to scratch the drum if internal.

I've bought a few of those with mixed results...not so bad that I would forego ordering again, but not perfect, either. One out of three I ordered quickly developed a problem which produced a white streak down the middle of the page. Looking into the cartridge, I could see that toner was not getting to that area. I replaced it with a NOS genuine Hp part I'd also ebayed, but I've got the bad one for further scrutiny if I ever need it...or as a source for replacement toner.

A guy I know that repairs printers says that how the stuff was stored is important for NOS toner carts. He recommends a quality refil service. YMMV.

Hi Kony,

Thanks a lot. Exactly this is what I was looking for, very good piece of info.

Thanks again

I refilled my cartridge successfully. Yes it is bit messy but good if you want to save money!!

Thanks

Just curious. What does it cost to fill one yourself, and where do you get rhe toner?
