Frequently Asked Questions

A fax machine decides for itself when to print — how fast will it use up 2,100 pages?

Faster than you might expect, because the L100 prints what other people send, not just what you choose to print. A quiet line receiving a handful of faxes a week can stretch this cartridge past a year, while a busy office line pulling in contracts, orders and referrals all day can work through 2,100 pages in a few months. Received faxes are usually plain text, which is gentle on toner — but the volume is set by your senders, and that is the honest reason fax lines go through cartridges on their own schedule.

What does $26.19 really work out to on a fax line?

Roughly 1.25 cents per page at the rated yield, and we will say plainly that a single cartridge is not the cheapest per-page way to buy Canon 128 toner. What it buys a fax line is a low one-time outlay and a cartridge in the machine today. If your L100 receives faxes around the clock and a dry cartridge would mean missed documents, the multi-pack versions of this same cartridge cut the per-page cost — but there is nothing wrong with starting with one.

If the toner runs out in the middle of the night, do I lose incoming faxes?

On a machine like the L100, incoming faxes are held in memory when the printer cannot print them, and they come out once a fresh cartridge is in. Memory is a buffer, not a warehouse, though — a long weekend with a dead cartridge and a busy line can fill it. That is exactly why fax-dependent offices keep the next cartridge on the shelf rather than on an order form: swapping takes a minute, and the stored faxes print as soon as the machine is back.

Is this the cartridge my FAXPHONE L100 takes?

Yes — this listing is the Canon 128 cartridge for the Canon FAXPHONE L100, and the check takes seconds: pull the cartridge that is in the machine now and read its label. If it says 128, this is the same cartridge family, and the change is the one you already know — open the cover, lift the old unit out, slide this one in until it seats, close the cover. No tools, no settings, and the machine picks the fax line back up on its own.

My received faxes are coming out faint on one side — is the cartridge finished?

Probably not. Toner settles toward one end of the cartridge over time, especially in a machine that sits idle between fax bursts. Take the cartridge out, hold it level with both hands, and rock it gently side to side a few times to spread the powder evenly, then put it back. If the next fax prints evenly, you have just recovered pages you already paid for. Evenly pale output that does not respond to rocking is the true sign the cartridge is done.

What am I covered by if this cartridge leaks or prints badly?

A 1-year warranty and 1-year free returns stand behind every cartridge we sell, so a defective unit, a leak or output that never comes right is our problem to fix, not yours to absorb. The details live on our shipping & returns page, and a real person answers questions Monday through Friday, 9 AM to 5 PM CST.
