CLP 300 toner cartridges don't have a chip

If you refiil the toner cartridge ,now must be change the cartridge chip.The chip countered the total copy,not how many time you refill the toner.The original chip working 1500 copies,change one new chip to 1,5K or 3 k or moreK(K=1000 copies).

Did you change the chips in the cartridges after you filled them with toner? Inside the cartridges are chips that the printer keep track of the number of images that are printed. After so many pages, the printer marks the cartridge as empty, even if you fill it with toner. When the cartridge is changed the printer reads the serial number on the cartridge and keeps a log it its memory. If the chip is replaced, then the printer does not recognize it and thinks it is a new cartridge.

Hope this helps.

ean_inkrefills on ebay. Search on the terms "samsung clp 315 toner refill solution". Chip installs on the printer motherboard--installation is not overly difficult, but still not for the faint-hearted. I expect it voids the printer warranty. Ean gives good email support.

The chips on cartridges are causing the problems.

the drum has chips encoded,need cartridges with chips.

No need to drill holes. If you turn the cartridge with the drum facing away from you, on the left hand side, you should see a small block elliptical cover with a couple of divider on it. That is the cover for filling the cartridge. The problem is there is no available reset chip yet for clp-315.

bad chip on toner cartridge.

The only way to reset it it to buy oem cartridges because it only lets you use the starter tanks once, after that they must have chips

If this IS a CLP-510, first make an information confirmation print.
Press MENU, then press ENTER, and ENTER again.

Look at the counter for the imaging unit, is it a low count confirming that you have indeed replaced it ?
If not you will need to reset the counter.

Check the counters for the toner cartridges, and check the capacity of the cartridge. On a CLP-510 the image counter for the toner is held on the chip on the cartridge (which also identifies the capacity of the cartridge).

There have been some faulty (oiginal Samsung chips), and of course re-manufactured cartridge chips could fail (many re-manufacturers don' test their cartridges before dispatch, they don't have the facility to do so without starting the count on the chip (or 'bowing' the reset fuse on a CLP-500 cartridge). VERY few re-manufacturers can test these cartridges without starting the count.

Sometimes the 'replace xxxxx toner' messages are caused by toner on the three contacts on the side of the cartridge, or their mating contacts inside the printer. Rarely, this can be caused by a faulty circuit board.

try to swap the chip on the toner cartridge with the original toner cartridge
