How do you sqeeze the last bit of toner out of my print cartridge?

My printer is a Brother MFC 8440 %26amp; our local supplier is out of stock until next week. I'm told that vacuum in the toner cartridge causes the printer to detect that it's empty, even though there is toner left. I shook the cartridge once and got another week out of it, but now it says tone empty again. Have a week before more stock comes in. Are they easily refilled by a novice? Cartridges are the TN-540 or 560.How do you sqeeze the last bit of toner out of my print cartridge?
Do what I do. PLace the cartridge on the edge of a counter..then take something long and thin like a knife handle, then place the handle part flat against the cartridge, With gentle, but firm pressure, press down and forward with one hand while hold the end of the cartridge with the other...basically you want to squeeze the toner left in the cartridge toward the opening, so that the printer will see that the top still has some left and will stop trying to squeeze the bottom.








Oh wait, was that for toothpaste or toner...erm...








Yes they are easily filled. Why though? why not shake shake shake, shake your groov...uh shake it again?How do you sqeeze the last bit of toner out of my print cartridge?
The simplest solution is to ALWAYS have a spare cartridge.





I am not familiar with your specific cartridges, but many CAN be refilled easily.


They sell ';refill kits'; for many different types.
Give it another good shake and cross your fingers.





No, toner cartridges are not refillable by end users.
