Frequently Asked Questions

Our D570 prints in bursts — heavy at month-end, idle in between. How does this cartridge handle that pattern?

Very comfortably. Toner is a dry powder, so an idle spell costs a cartridge nothing: no drying out, no clogging, no maintenance printing to keep it alive. The 137 simply waits inside the imageCLASS D570 until the month-end run arrives, then delivers its rated capacity on demand. A 2,400-page cartridge absorbs a 500-page month-end burst and still has most of its life left for the quiet weeks. For bursty users, the practical pattern is one cartridge lasting several monthly cycles — at $27.70 total, the cost of that whole period's printing is about 1.15 cents a page.

First pages after a quiet spell sometimes look uneven. Why, and is it a fault?

It is settling, not a fault. During weeks of inactivity the powder inside the cartridge can rest unevenly, so the first pages of the next run may look slightly patchy. The fix takes a minute: remove the cartridge, rock it gently from side to side several times to redistribute the toner, refit it, and the run continues at full density. Build that one step into the start of each month-end session and you will rarely think about it again. If unevenness persists well into a run, that is a genuinely aging cartridge rather than a sleepy one.

How should I plan capacity around a big monthly run?

Count backwards from the burst. If month-end means roughly 600 pages of statements, invoices or reports, one fresh 137BK covers about four such cycles at standard text coverage — but only if quiet-week printing stays modest. The safer office habit is to start each peak period knowing the cartridge's approximate age: if it has already done two heavy cycles, have the spare in the building before the third begins. Peak weeks are precisely when a printer cannot be allowed to stop, and a $27.70 spare is the cheapest schedule protection available.

Does printing 300 pages in one afternoon differ from 300 pages across a month?

For the cartridge, barely at all. Toner consumption is per page, not per session: 300 pages is 300 pages of wear on the supply whether they run back-to-back or one at a time. Long runs are if anything tidier — the toner stays distributed and density stays even from first page to last. The 2,400-page rating holds under both patterns, assuming ordinary text coverage of about 5%. Where bursty users do feel a difference is timing: consumption arrives in cliffs rather than slopes, so the low-toner warning tends to appear mid-burst, which is another argument for the shelf spare.

Is it wasteful to replace a cartridge that still prints fine after a long idle period?

Yes — do not replace on age alone. A 137 does not expire in the machine on any timescale that matters to a monthly user. Replace when the evidence says so: fading that a shake no longer fixes, or a low-toner warning followed by declining density. Owners who swap cartridges by the calendar rather than by output throw away real pages; a cartridge fitted in January may still be delivering honest work in June if the D570's total volume is low.

What cover backs the cartridge if a peak-week run goes wrong?

Every compatible 137 carries a one-year warranty and one-year free returns, detailed on our shipping and returns page. If a cartridge fails during your busiest week, support is available Monday to Friday, 9 AM to 5 PM Central, and stock ships from warehouses in Illinois, Pennsylvania, Georgia and California, so a replacement is measured in days, not weeks.
