Review on 🖨️ TM-Toner Reset Chips for Ricoh Aficio SP C250SF/DN - Refill 4 Color Toner (407539-542) by Shaun Stapp

All 3 of our entry level color cartridges suddenly showed 'empty' at around the same time. These reset chips came quickly from Prime and are very similar to the factory chips. Old chips are not easy to remove as there are tabs on each side to hold them in place. I used an X-acto knife and nearly destroyed one of the burrs on the first chip removal. Luckily the new chip is still on tight enough that I don't have to use a piece of tape to hold it in place. If you must use tape, make sure you don't cover the gold contacts on the chip. I also recommend wearing safety goggles or goggles. One of the old chips flew out fast enough to injure the eyes. The first ones are the hardest, and each time they get easier. A good product that allows you to completely empty the cartridges before replacing them.
