Review on 🖨️ Do it Wiser Compatible Toner Cartridge Replacement for Samsung CLT-K504S - 4-Pack: Optimal Performance for Samsung Xpress C1860FW C1810W SL-C1860FW SL-C1810FW CLX-4195FW CLP-415NW by Chris Rob

I bought these toner cartridges for my Samsung and replaced 2 color toners and didn't use the printer for a week before noticing the problem. It looks like the quality is set to low and fast to save ink. I checked my settings again and set it to the best quality and it had no effect. Now I need to replace the ink again and it's been over 30 days so I can't get a refund.
