Frequently Asked Questions
Our C3010DW prints documents all day — how long will one of these last us?
Work it from your own volume. The CLT-K503L is rated at 8,000 pages, so an office printing around 1,000 pages a month gets roughly eight months from one cartridge; at 400 pages a month it is nearer twenty months. Check the C3010DW's page counter today and again in a month — that difference is your true monthly figure, and it predicts the change date far better than any rating.
What are the signs this cartridge is coming to its end?
Text that fades towards one side of the page, grey or streaky patches on documents that used to print solidly, and the printer's low-toner message are the usual sequence. There is normally a useful reserve after the first warning, but on a document-heavy machine the sensible move is to order when the warning appears rather than when pages turn pale.
Does printing in colour drain the black cartridge as well?
Partly. On a colour page, the text and dark elements are still laid down by the black cartridge, while the CLT-C503L, CLT-M503L and CLT-Y503L handle the colour areas. Pure text pages use black alone. That is why the CLT-K503L empties first even in offices that think of themselves as colour printers.
Is this the right cartridge for the ProXpress C3010DW?
Yes — the C3010DW's black supply is the CLT-K503L, rated at 8,000 pages. The same cartridge also serves the ProXpress C3010ND, ProXpress C3060F and ProXpress C3060FW, so offices running a mix of those machines can standardise on one black cartridge.
Should we choose this or the standard-capacity black?
The standard counterpart is the CLT-K503S; this CLT-K503L is the high-yield version at 8,000 pages. For a C3010DW in daily document service, the longer interval between changes is usually the deciding factor — the printer stays in service instead of waiting on a swap every few weeks.
What cover does this cartridge carry?
A year's warranty against defects, and your purchase can be returned free of charge at any time within the first year — the details are on the shipping and returns page. Support is available Monday to Friday, 9 AM to 5 PM CST.
