How To Refill Toner For Brother Hl-4040cdn Laser Printer? Websites Or Videos Or Reasonable Toner Refill Kits?
The replacement cartridges cost as much as the printer. Seeking most economical route possible.
Would prefer to refill with toner.
Buy a refurbished cartridge, that will save you money. Refilling a toner yourself is never a good idea simply beacuse toner cartridges are mechanical, there are parts which need to be replaced, such as the electrostatic roller, chips and a gearing assembly.
Because your toner sits in a drum, if you improperly fill the toner or it seizes it will ruin the drum. Now if you think the toner is expensive, just wait until you need to replace the drum.
Buy a third party or re manufactured toner. It will save you money and mess.
No, websites or videos is clearly an option
“Refilling a toner yourself is never a good idea simply beacuse toner cartridges are mechanical, there are parts which need to be replaced, such as the electrostatic roller, chips and a gearing assembly.”
I agree Smedrik, mechanical parts do need replacing but in my experience after 3 or 4 complete refills of the cartridge not one ! The whole point is you don’t touch the mechanical parts at all with every cartridge I’ve refilled. Your presuming that they aren’t so badly made that they need replacing after one print run.
Why would you replace the drum? Replacing the toner on so many printers now costs more than a complete new printer anyway never mind the drum.
