What are the laser MFPs with easy refilling?

Question

Seal

Tell me if there are such laser MFPs that you can refuel yourself.
Is it true that inkjet MFPs are easy to fill with a regular syringe, but consumables are expensive and dry out quickly?
I found answers on the toaster, but they are old. I want something modern.

Answer 1

Tell me if there are such laser MFPs that you can refuel yourself.

My device is Samsung Xpress M2070
I have a large bottle of dry ink (powder), open the cartridge valve, fall asleep and that's it.
The work is easy, but dirty, it is better to do it in some kind of box and in a respirator and gloves.
This is the refill toner I use.
My device is Epson Stylus T50 Partly
. But in order for the ink to really dry out, you need to print nothing at all for months.
Even with rare printing, the head is cleaned and the ink does not dry.
Yes, they are refilled with a regular syringe. I have PZK (1). But I think to change to CISS (2).
I must say right away that I fill it without even removing the rubber valve because the cartridges already need to be changed.
If you're in charge, then shoot. Will last longer.

1) PZK - refillable cartridges
2) CISS - continuous ink supply system

Answer 2

Refueling bypassing the manufacturer's rules is a whole industry ....
Fake chips, etc. ...
Read better profile sites.
And so, offhand - the older Kyocera models were initially sharpened for a simple filling of toner. There is no concept - "buy a new cartridge."
