Frequently Asked Questions
The low-toner warning just appeared on our CLP-620ND — how much printing is really left?
More than the warning's tone suggests. The message is triggered with a deliberate reserve still in the cartridge, so ordinary printing continues normally for a while — typically a few hundred pages at everyday coverage. Treat the warning as your ordering signal rather than a countdown to failure, and the replacement will be on the shelf before the reserve matters.
What does this cartridge cost per month in a CLP-620ND that prints every workday?
Work it from your volume: at a thousand pages a month, the 2,500-page CLT-K508S lasts about two and a half months, putting black toner at roughly $23 a month against the $56.81 cartridge price. Double the volume and the cartridge turns over in five weeks or so. Either way, the rated cost behind the estimate is about 2.27 cents a page.
Can we keep printing after the warning without harming the printer?
Yes. Running a cartridge into its reserve does the machine no harm at all — the only consequence is gradual: blacks lose their depth, then grays turn uneven, and eventually pages are too faint to send out. Swap in the fresh CLT-K508S when quality drops below what you would hand to a customer, and not a page before you need to.
Which printers is the CLT-K508S listed for?
Your CLP-620ND heads the list; the same code is the listed black supply for the Samsung CLP-670N. The confirmation is printed on the cartridge already inside your machine — if the spent unit reads K508S, this box holds its exact replacement.
Where will the cartridge be shipped from?
From the closest of our four warehouses — IL, PA, GA or CA — chosen by your delivery address, as a single tracked shipment. The complete picture on delivery and on sending anything back is published on the shipping and returns page.
What stands behind the cartridge once it is fitted?
A one-year warranty against defects, and the right to return it free of charge at any time in the first year after purchase. If a question comes up mid-life rather than at fitting, the support team is available Monday to Friday, 9 AM to 5 PM CST.
