Frequently Asked Questions

Before anything else: what does one page actually cost with this cartridge in an LBP151dw?

The maths is simple and it is the reason most people buy the 137 this way. The cartridge costs $27.70 and is rated at 2,400 pages, which works out at roughly 1.15 cents per page for toner. Spread over the life of the cartridge, that is $27.70 buying you around forty-eight standard office documents of fifty pages each, or well over two thousand single-page letters, invoices and forms. When you compare cost per page rather than the sticker price of the box, the 137BK is an inexpensive way to feed an LBP151dw — there is no cheaper line item in your printing budget once paper is accounted for.

Is the 2,400-page figure realistic, or a best case?

It is a standardised rating, measured at roughly 5% page coverage — about the amount of toner on a typical page of business text. Ordinary correspondence, emails printed out, invoices and reports sit close to that level, so most LBP151dw users land near the rating. Pages with large bold headings, shaded tables, logos or full-page graphics use more toner per sheet and bring the total down; light text-only pages can push it above 2,400. Treat the figure as a dependable planning number rather than a promise to the last page.

How long will one cartridge last in a home office?

Work backwards from your weekly volume. At 50 pages a week, a 137 lasts close to a year. At 150 pages a week it lasts about four months; at 300 pages a week, roughly two months. The LBP151dw is a personal and small-team printer, and for that pattern of use a single cartridge is a long-lived supply — most owners order two or three a year at most, which makes the annual toner spend on this printer easy to predict: around $55 to $83 at typical volumes.

Does using toner-save or draft mode stretch the cartridge further?

Yes. Toner-save settings lay down less toner per page, which lightens the print slightly but can extend the useful life of the cartridge noticeably, especially on internal drafts you will never show a client. A sensible routine for the LBP151dw is to draft in toner-save and switch to full quality only for final copies. It costs nothing to set up, and on a 2,400-page cartridge even a modest saving per page adds up to extra weeks of printing.

What does the low-toner warning actually mean — is it time to order?

The warning appears while there is still usable toner in the cartridge, so it is a prompt to order rather than a stop signal. Depending on your page coverage, you may get anywhere from a few dozen to a few hundred more pages after it first shows. Because a replacement ships from one of our warehouses in Illinois, Pennsylvania, Georgia or California, ordering when the warning appears normally means the new 137BK arrives with days to spare. If your LBP151dw cannot sit idle, keep one sealed spare on the shelf and rotate it in when the old cartridge finally fades.

What cover do I get if the cartridge lets me down?

Every compatible 137 we sell is covered by a one-year warranty and one-year free returns, so if a cartridge fails early or prints poorly you are not stuck with it. Full terms are on our shipping and returns page. If you are unsure whether a problem is the cartridge or the printer, our support team is available Monday to Friday, 9 AM to 5 PM Central, and can talk you through a couple of quick checks before you send anything back.
