Here's how to replace toner cartridges on your Dell E525w Laser Printer. Switch the power off, then open the toner access cover. Pinch the toner lifting the blue lever to unlock then pull to remove it.
Unpack, then gently shake your new cartridge to distribute the toner. Remove the tape, then insert the cartridge. Push until you hear the click. Close the toner access cover, then switch the power on.
You can buy replacement toner online at dell.com/supplies. To recycle old toners go dell.com/recycling.
Thanks for watching.
