Can I refill my laser toner cartridge? I do not recommend using refill kits for toner cartridges. When PrintCountry.com sells remanufactured laser toners, they always replace it with the new drum. You might also need to change other parts of your laser toner for satisfactory results. Since refilling a laser toner is a messy process and involves changing parts, most companies don't sell refill kits for laser toners.
"FOR THE FIRST TIME EVER I HAVE OBTAINED A RE-INKING KIT THAT REALLY WORKS!!! THE SECRET, I THEORIZE, IS THAT CARTRIDGE HARNESS AND PULLING THE AIR BUBBLES AND A SMALL AMOUNT OF INK FROM THE BOTTOM OF THE HARNESS AFTER RE-INKING. I SUPPOSE THIS IS WHAT GETS THE INK FLOWING PROPERLY AGAIN AND IT IS A GREAT IDEA THAT WORKS!!!!! ALSO AFTER RE-INKING ACCORDING TO YOUR METHOD AND INSTRUCTIONS I DID NOT RECEIVE FOR THE FIRST TIME EVER AN HP PRINTER NOTICE THAT THE INK CARTRIDGES WERE STILL LOW ON INK. THE HP PRINTER TREATED THE NEWLY RE-INKED CARTRIDGES AS BRAND NEW AND THE TEST PRINT PAGE CAME OUT PERFECT." (Michael K.)
