Frequently Asked Questions
How can I be sure this single cartridge matches the one I just pulled out?
Read the label on the old cartridge. If it says TK8309K, this is the same black cartridge, made for the TASKalfa 3050ci. The number matters more than the look of the box, so match that code and you have the right unit. One cartridge is $78.63.
What does one cartridge cover in everyday office use?
It is rated at 15,000 pages at standard coverage — the level of print on typical letters, invoices, forms and reports. Offices printing mostly documents of that kind get a long, predictable run from a single TK8309K before the low-toner warning appears.
What is involved in installing it?
Very little. Open the printer's front cover, slide the empty cartridge out, unpack the new one and rock it gently from side to side so the toner settles evenly, then slide it in until it locks. Close the cover and print a test page. No tools, no settings to change, no technician.
The first pages look light — does that mean the cartridge is defective?
Usually not. Take the cartridge back out, rock it side to side a few times to redistribute the toner, and print several pages; output normally evens out. Also confirm the printer is not set to an economy or toner-save mode. If pages stay faint after that, contact us — the cartridge is protected either way.
What protection comes with a single cartridge like this?
The same as with our larger packs: a 1-year warranty and free returns for a full year, with support available Monday through Friday, 9 AM to 5 PM CST. A single-unit purchase is not treated as a lesser order.
When will it get here?
Your cartridge ships from the closest of our warehouses in IL, PA, GA and CA. Delivery estimates and return instructions are gathered on our shipping and returns page.
When should I order the next single — at the warning, or when the printer stops?
At the low-toner warning. The cartridge still holds a small reserve at that point, so you can finish the day's work and have the replacement in hand before the slot actually stops. Ordering only when the printer halts means downtime while the delivery is in transit, and for a machine that prints all day, that gap is the expensive part of the order.
How can I tell whether faded text is the cartridge or the printer?
Fit the fresh TK8309K, then print the machine's test page and compare it with the last good pages the old cartridge produced. If the black areas are solid across the whole sheet, the cartridge is fine and the earlier fade was simply the spent unit. If bands or streaks appear in the same place on every page, note the pattern before you contact support — a repeating mark points at the machine rather than the cartridge.
Do dense forms and shaded tables really use that much more toner?
Yes. The 15,000-page rating assumes standard coverage — the level of print on ordinary letters, invoices and reports. Pages carrying solid fills, shaded tables or bold graphics lay down far more toner per page, so an office whose work is mostly that kind of page will finish a cartridge well short of the rating. If that is your mix, plan reorders on your own observed run rather than on the rated figure.
If I buy a second TK8309K as a spare, how should I store it?
Sealed in its box, lying flat in a cool, dry spot away from direct sunlight and heat, with the label facing out so the code is readable without opening anything. Toner does not dry out the way liquid ink does, so a properly stored spare simply waits. When its turn comes, rock it gently side to side before fitting to level the toner that settled in storage.
