TASKalfa 520i

Kyocera TASKalfa 520i printer

Speed is the TASKalfa 520i's reason to exist. It lifts the same monochrome multifunction platform as its 420i sibling into the 50-page-per-minute class — up to 52 pages per minute — yet it deliberately keeps the same supply: the TK-717 (TK717) black toner cartridge, rated at 34,000 pages per ISO/IEC 19752 and sold in Europe as the TK-725. The faster engine never forces a second toner onto the shelf.

This is the machine for the floor where the printer never really rests. Long runs, back-to-back copy jobs and end-of-day report batches are its daily diet, and a 34,000-page cartridge matches that tempo: toner changes stay rare events even when the page counter climbs fast. Facilities teams like the pairing for another reason — one cartridge number covers both the 420i and the 520i, so the supply cabinet holds depth instead of variety.

Toner Cartridges for TASKalfa 520i

TK-717 (TK717) — Black, single cartridge, 34,000 pages
TK-717 (TK717) — Black, 2 pack, 34,000 pages per cartridge
TK-717 (TK717) — Black, 4 pack, 34,000 pages per cartridge

Which cartridge should you buy?

Choose by how painful an empty machine would be. A single TK-717 already delivers about 34,000 pages, which a moderate workgroup may take months to spend. High-throughput floors tend to keep the 2 pack as their standing stock: when the first cartridge finishes mid-queue, its twin is steps away rather than days away. The 4 pack fits sites that centralize purchasing — four cartridges, roughly 136,000 pages of coverage, the lowest cost per page of the three, and one less line item to reorder all year.

Chip, toner and everyday use

A chipped cartridge lets the 520i verify the supply and report toner levels, so push the cartridge in until it seats and allow the recognition cycle to finish before queuing a big job. Treat the 34,000-page figure as a benchmark at about 5% coverage, not a promise — coverage-heavy work consumes toner faster on any machine. If output fades near the end of a cartridge's life, removing it and rocking it gently side to side can even out the remaining toner for a few more clean pages. Keep the next cartridge sealed, flat and indoors until swap day.

Frequently Asked Questions

What is the difference between the TASKalfa 420i and 520i?

Pace. The TASKalfa 420i runs at up to 42 pages per minute; the 520i reaches up to 52. Both use the identical TK-717 toner cartridge, so stepping up in speed does not change your supplies.

Which toner does the TASKalfa 520i use?

The TK-717 black cartridge — the US designation for the TK-725 — rated at approximately 34,000 pages per ISO/IEC 19752.

How many pages will one TK-717 print?

Around 34,000 pages at roughly 5% coverage. Real-world totals move with what you print: light memos stretch the cartridge, dense forms and graphics shorten it.

Does the TASKalfa 520i need drum replacements?

Not as a routine supply. Kyocera builds this platform around a long-life drum intended to last the machine's service life under normal use, leaving toner as the regular replacement.
