Uni-Kit Toner Refill Kit for Samsung CLP-310 CLP315 (Black). Instructions, toner pouring nozzle.
Samsung has made these cartridges with a "lock-out" chip that will force your printer into not accepting a refilled cartridge because it "remembers" it as empty. While we sell new chips that will override this "lock-out" mechanism, you may also REFILL IT BEFORE IT COMPLETELY EMPTIES. Please be sure to refill the cartridge when the ink status shows 25% of the toner is left in the cartridge. Do not wait for it to say "Toner Empty" as it will have locked out by then. The number of refills you can get before it locks-out varies, we have tested it to work for between 1-3 refills before it will inevitably lock out and a chip needs to be replaced.
