Buying a printer you will only use a few times a month

HP describes the mechanism directly in its own document on how it measures ink page yields. It says some inkjet users print a few pages at a time, and hours, and sometimes days, pass between print jobs; with that kind of start/stop printing, inkjet printers use some ink to keep print nozzles clear and ink flowing smoothly. HP calls this critical to maintain the health of your printer, and states plainly that it can cause your yields to be lower than if you printed the same content continuously. That is the whole mechanism. The ink is not evaporating and it is not being stolen. It is being spent on purpose, by the printer, to stop the nozzles drying out between your jobs.

A note on that source. The document is HP-authored and the passages above are quoted from it, but it is undated, and the only copy we could open is hosted on a retailer's asset server. HP's own inkjet counterpart at hp.com/pageyield returned 404 on the access date, so no HP-hosted version was reachable. The HP-hosted mono-laser article cited elsewhere on this page did load.

Epson publishes the same idea as a standing footnote on its ink products. On the 522 ink bottle page, Epson states that yields may be lower when printing infrequently or predominantly with one ink color, that all ink colors are used for printing and for printer maintenance, and that all colors must be available for printing. That footnote appears on bottles for cartridge-free EcoTank machines, so the maintenance behavior is not something you escape by moving from cartridges to tanks.

This is the same sentence read a second way. Epson's requirement that all colors must be available for printing is a requirement, not a preference. Epson's support FAQ for the WorkForce WF-4820 and WF-4830 — ordinary household-class machines — explains why. Epson states that its printers contain a permanent print head that needs to be charged with all colors to work, that to keep the print head clear and ready to print the printer uses a small amount of ink from all the cartridges whenever it prints, and that the head needs to be kept charged to prevent air bubbles from entering and damaging it. Epson publishes the same explanation as a shared FAQ attached to other machines as well, including the large-format Stylus Pro 11880. So the refusal is a protection of the hardware, not a sales tactic — which does not make it less annoying, but does mean no setting will switch it off.

Brother documents the same lockout with one concrete exception. Brother's support FAQ for the MFC-J5625DW states the machine is designed to stop all printing operations when any ink cartridge is empty, but that it can exceptionally run in a Black and White Print Only mode when one or more color cartridges are empty. Brother gives that mode a stated duration: approximately four weeks, depending on how many pages you print. Two things cancel it. Unplugging the machine may clear the memory. Removing the empty cartridge and closing the cover produces a Cannot Print display. If you own a Brother inkjet and a color runs out the week before you need something printed, that four-week window is the thing you are actually working inside, and leaving the dead cartridge physically in place is what keeps it open.

The four-week figure is Brother's, for that model, on Brother's UK support site. Other Brother models may behave differently. Look up the same FAQ for your own model number before relying on it.

Declared yields are measured by printing continuously. HP's own description of the ISO 24711 method is that a standard set of five pages is printed continuously until the cartridge reaches end of life. ISO/IEC 24712, the standard that defines those pages, describes a suite of four customer-type documents plus one diagnostic page used to determine end of consumable life. HP says outright that ISO yields should be used as a starting point for comparison, not to predict the actual yield you will get, and that actual yield varies with frequency of printing among other factors.

Put those two statements together and the conclusion follows: a cartridge declared at 200 pages will not deliver 200 pages in a machine used twice a month. That is an inference from HP's and Epson's own statements — that the test prints continuously, and that intermittent printing spends ink on maintenance — not a measurement made here. No manufacturer we found publishes how much ink the maintenance cycle uses, so nobody can tell you what fraction of the declared yield survives. What you can take from it is that for a light user the declared number is an optimistic ceiling, and comparing two inkjets on declared yield alone compares them at a usage pattern neither of you will have. The arithmetic of comparing yields against price is covered on the cost-per-page guide.

Laser and LED machines are electrophotographic — that is the word in the title of ISO/IEC 19752, the mono toner yield standard. There is no printhead and there are no nozzles, so the idle-time maintenance cost HP describes has no mechanism to act through. We should be precise about the evidence: none of the laser pages we opened contains any statement about infrequent printing, positive or negative, whereas Epson's ink footnote states one explicitly. Absence of a warning is weaker evidence than a warning, so treat this as inferred rather than confirmed by a manufacturer.

What lasers can add is a second consumable. Brother's HL-L2350DW takes a TN730 or TN760 toner cartridge and, separately, a DR730 drum unit. Brother rates the TN760 at about 3,000 pages under ISO/IEC 19752 and the TN730 at up to 1,200 pages under the same standard, and the DR730 at about 12,000 pages, noting only that drum yield is approximate and may vary by type of use — Brother names no direction and gives no example, and neither will we. HP's LaserJet M110we data sheet, by contrast, lists exactly one supply: the W1420A / HP 142A toner cartridge at 950 pages. No drum appears in its supplies list, and HP elsewhere in the same document refers to integrated cartridges with toner and drum in one. Same technology, different number of things to buy.

Before you treat that as a reason to choose, finish the arithmetic. Brother lists the DR730 drum in the printer's carton contents, so it ships in the box; it is a replacement cost, not a purchase cost. And 12,000 pages at five pages a month is 2,400 months, which is two hundred years. At this reader's volume the second consumable is a bookkeeping difference, not a cost difference. The drum count matters to heavier users, and to anyone buying second-hand who may be inheriting a part that is already part-used — not to someone printing five pages a month. Counting consumables is worth doing, but it is not the deciding field.

The deciding field on these two machines is something else, and it is printed at the head of HP's own data sheet: this is an HP+ printer, and HP states it requires an HP account, connection to the internet, and exclusive use of Original HP Toner cartridges for the life of the printer. For someone who prints five pages a month, that is the material fact. It bears directly on whether the machine will print when asked — an account-and-internet dependency is a thing that can fail on the day you need a form — and it permanently forecloses any non-HP toner. Brother's data for the HL-L2350DW states no equivalent requirement. That is the difference worth weighing, and it is the opposite of the one a consumable count would have pointed you toward.

These sources straddle markets, which matters for everything except the ISO yields. The HP M110we document is the EMEA edition — it quotes euro figures, specifies 220-240V, and is marked gr-en January 2024. The Brother TN730, TN760, DR730 and HL-L2350DW pages are brother-usa.com. The Brother MFC-J5625DW lockout FAQ is Brother UK. ISO yield figures travel between regions; model availability, supply part numbers and in-box contents do not. Check your own region's page for the configuration actually sold to you.

Ink tank machines change how often you buy, not how the printhead behaves. Epson states the ET-2800 ships with up to two years of ink in the box, and is explicit that this is based on average monthly document print volumes of about 125 pages. Replacement 522 bottles are stated at 4,500 black and 7,500 color pages. Those are large numbers and the reduction in replacement events is real. But the maintenance physics is unchanged: the same Epson footnote about infrequent printing and all colors being available appears on the 522 bottles themselves.

Epson separately sells ink maintenance boxes, which it describes as storing ink that gets flushed from the system during print head cleaning — the same maintenance ink, collected rather than avoided. Do not assume your machine has one. Epson's T04D1 maintenance box page lists roughly thirty compatible EcoTank, Expression and WorkForce models, and the ET-2800 is not among them; no maintenance box appears in the ET-2800's own supplies list either. This is a check-yours case. Look up your exact model against Epson's maintenance box compatibility list before assuming a replaceable part exists. Where the flushed maintenance ink goes on a model with no listed maintenance box is a question Epson's consumer pages do not answer, and we will not answer it for them.

There is also a scale mismatch worth naming. Epson's two-year claim assumes about 125 pages a month. Five pages a month is one twenty-fifth of that — the arithmetic is ours, from Epson's stated basis. You would be buying a supply system sized for someone printing twenty-five times as much as you. The same arithmetic runs across every machine here and is the more interesting result: at five pages a month, a 3,000-page TN760 is about fifty years' worth on paper, a 1,200-page TN730 about twenty years, a 950-page HP 142A just under sixteen, and a 4,500-page bottle of 522 black about seventy-five. For a genuinely light user, declared yield stops being the constraint at all. The constraints become whether the machine will print when asked, what it requires of you to do so, and how many separate parts you have to keep track of.

No manufacturer or standards document we opened publishes a maximum safe idle period for an inkjet printhead. We searched for one and did not find it, which is not the same as proving none exists. The advice that an inkjet must be run every two or three months circulates widely — it appears, for instance, in a reply on a technical forum thread where someone asks which inkjet survives long periods of non-use — but we could not source that interval to any manufacturer or standards document, and this site will not assert it. What is published is everything above: that maintenance ink is spent between jobs, that all colors must be available, and that declared yields assume continuous printing. That is enough to choose a technology. It is not enough to tell you how long your specific machine can sit.

Before comparing anything, get an actual number instead of an estimate. Do not guess your monthly volume — reconstruct it.

1. Find the dates of your last two or three cartridge changes. Order history, a receipt, or the date written on the old cartridge will do.
2. Divide the declared yield of that cartridge by the number of months between changes. That gives an upper bound on your pages per month, because you almost certainly did not reach the declared yield.
3. Check you are using the right yield figure. A cartridge that came in the box is often a starter rated well below the replacement part with a similar name — Brother's HL-L2350DW ships with a starter rated about 700 pages, while the TN730 replacement is rated up to 1,200. If you are measuring against the in-box cartridge, use the in-box figure.
4. Compare that figure against the declared yield of any cartridge you are considering. If the answer is decades, yield is not your problem and you should choose on the other criteria below.
5. If your printer has a built-in page counter — often in a configuration or status report printed from the control panel — use that instead; it is a direct count rather than an inference.

Every figure in the table above came from a manufacturer page, and you can read the same fields for any model you are considering. Here is where each one lives and what it decides. If you are also trying to identify a replacement part for a machine you already own, the cartridge identification guide covers that separately.

Then do the last step, which takes about a minute. Open the manufacturer's specification page for the exact model number you are considering — not the family name, the full model number. Read the head of the page for any account or connection requirement. Read the consumables list and count the items, then read the carton contents to see which of them you already have. Read the yield footnote and note which standard it names. That is the real cost and the real condition of ownership as the manufacturer states it, and it is the only version of either that anyone has actually published.
