Frequently Asked Questions

How can I confirm this 370AB011 is the cartridge my machine calls for?

Read the part number, not the silhouette. 370AB011 is stamped on the label of the cartridge sitting in your copier right now and also appears in the machine's supply information. When that code matches what you see, this single black cartridge at $101.81 is the correct refill — no measuring, no photo comparisons needed.

What exactly shows up when the box arrives?

One individually sealed compatible black toner cartridge, rated at 34,000 pages. It travels in protective packaging and goes straight from the box into the machine — there are no extra parts to order and nothing to put together first.

Can I swap it myself, or does this model need a technician?

You can handle it. Open the front panel, draw the spent cartridge out, guide the fresh 370AB011 in until it settles, and close the panel. The job takes about two minutes, asks for no tools, and the copier picks up where it left off.

The first copies after installing look washed out. Should I worry?

No. Toner settles into one end of the cartridge during transit. Take the unit out, rock it slowly from side to side a few times so the powder levels out, put it back, and copy a few ordinary pages. Output density normally evens out within the first short run.

What does a 34,000-page rating mean for a busy department copier?

The rating is measured on standard test pages at typical text coverage. On a workhorse machine turning out reports, invoices and forms all day, one cartridge covers a long stretch between changes; dense graphics and heavy fills will shorten that. Either way, it is a fit-it-and-forget-it interval for a high-volume unit.

What backing comes with this cartridge?

Each unit is covered by a 1-year warranty with free returns for the whole first year. If anything comes up, our support team is available Monday through Friday, 9 AM to 5 PM CST.

What does this cartridge cost per page?

At $101.81 for a 34,000-page rating, the 370AB011 runs at about three-tenths of a cent per page on standard coverage. That is the figure worth comparing when a department asks whether the big departmental copier is economical to feed: even allowing for heavier real-world coverage shortening the interval somewhat, the cost of the toner inside each copy stays a small fraction of a cent, which is exactly why these machines suit report and invoice volume.

How long can I keep printing once the copier says toner is low?

The low message arrives with reserve still in the cartridge, so a 370AB011 does not stop the machine the moment it appears — copies continue, gradually lightening as the remaining toner is consumed. Use the warning as your ordering trigger rather than a countdown: finish the job in hand if the output still looks right, but have the replacement on its way, because once density starts to fade across the whole page the cartridge is truly spent.

Does it matter which of my machines this cartridge goes into?

Only in the sense that it fits all of them. The same 370AB011 serves the KM-2530, KM-3035, KM-3530, KM-4030 and KM-4035, so a spare bought for one departmental copier is equally a spare for any other machine in that family. If two machines call for toner in the same week, the cartridge on the shelf can go to whichever copier stopped first, and the second machine's replacement simply becomes the next order.

What should I do with the empty cartridge after the swap?

Put the spent 370AB011 back into the packaging the new one came out of and send it through your workplace's toner recycling or disposal route rather than general office trash. One practical exception: if the old cartridge seemed to run out far sooner than its predecessor did, keep it aside until the new unit has produced a few days of clean copies — if questions come up, the empty itself is the first thing anyone will want to look at.
