Review on 🖨️ Do it Wiser Compatible Printer Toner Cartridge Replacement for Ricoh SP 4310N/SP 4100N/SP 4210N/SP 4110N, 402809 (15,000 Pages) by Brian Hrdlicka

Ordered 2 of these. I set it to 1 and it immediately swept across the left side. After a few prints, the print tone began to fade prematurely. Then I replaced it with a second one, and after about 50 pages it also started rubbing off and disappearing. I will not buy again. After this verification they contacted me and gave me a full refund. They said they had a bad batch. I'm willing to give them the benefit of the doubt and will likely buy them again in the near future. Your customer service representative was very helpful.
