Frequently Asked Questions

How do I make sure the D1370 never runs dry mid-job?

Hold one spare, always. This C120BK is rated for 5,000 pages, so a sealed backup on the shelf means the worst case is a two-minute swap, not a stalled job. When the spare goes in, that is your reorder signal — the replacement ships from our warehouses in IL, PA, GA and CA and lands long before the fresh cartridge is anywhere near empty.

Which cartridge am I sparing for?

The Canon 120, code C120BK — the single black toner cartridge the imageCLASS D1370 uses. One code to stock, one box shape on the shelf, and no possibility of grabbing the wrong colour, because this machine's printing is black-and-white from a single cartridge.

The low-toner warning just appeared. How urgent is this, really?

Not an emergency — a heads-up. There is a working reserve left in the cartridge when the warning shows. Rock the C120BK gently side to side and the remaining toner levels out, often restoring full darkness for a good stretch of pages. Order or swap on your schedule rather than the printer's.

What does the D1370's printing cost with this cartridge?

$32.42 buys a 5,000-page rating, which is roughly 0.65 cents a page. For a machine that handles an office's everyday documents, that keeps the D1370 firmly in cheap-to-run territory — and the multi-pack versions of the same Canon 120 cartridge trim the per-cartridge price further if you stock in quantity.

What if the spare I stored turns out faulty when I finally fit it?

It is still covered. Our compatible cartridges carry a 1-year warranty and 1-year free returns, so a cartridge that misbehaves when fitted is a returns conversation, not a loss. The process is laid out on our shipping and returns page, and support can help Monday to Friday, 9 AM to 5 PM CST.

Any storage rules for the spare?

Keep it sealed in its packaging, lying flat, somewhere cool and dry — a supply cupboard is perfect, a windowsill is not. Toner is dry powder; treated that way, a C120BK waits patiently until the D1370 asks for it.
