Review on 🖨️ V4ink Compatible Toner Cartridge for Canon 137 - Replacement for imageCLASS MF and LBP Series Printers (2Packs) by Jay Campbell

I installed one of the cartridges from the 2 pack V4Ink toner cartridge set I bought from Revain in a new Canon MF236n printer I recently bought (also from revain). The "starter cartridge" that came with your new device is empty. I am not happy at all with the print quality. The print density of characters on printed pages is uneven. Some are very tricky. Suspecting that maybe I didn't shake the cartridge enough before installing it, I took it out of the car and put it back in, shaking it a few more times. There were no improvements. I would like to return both cartridges for a refund and purchase a compatible cartridge from a supplier who supplied good quality compatible cartridges for the old Cannon printer that I replaced.
