HP LaserJet Tank MFP 2604sdw  Printer Review

This printer is well-built. It feels solid overall, with a dense plastic construction, sturdy hinges for various components, and no giant panel gaps. Its power cable is also completely detachable, so you can always buy a new one if you damage the original cord. That said, a few missing features would be welcome on a printer like this. The scanner's hinges can't extend to accommodate larger books or magazines, and the scanner's backing is a simple white plastic sheet that does a poor job of flattening any documents you put inside. The display panel folds upwards to let you insert the paper into the input tray. Folding it down covers the bottom paper tray.

User maintenance requirements are few. Unlike inkjet printers, there are no printheads that can clog over time. If you run into an issue while printing, you can run one of the built-in maintenance routines, like fuser cleaning, humidity and altitude adjustment, or paper curl compensation. You can also turn on archive print mode, which creates prints that are less likely to smear or fade.

The printer's drum unit isn't user-replaceable, with replacements having to be done through an authorized service provider. That said, this isn't likely to be much of an issue, as it has an estimated lifespan of roughly 50,000 prints, which is plenty even if you're the type to print multi-page documents on the regular. Of course, this component's lifespan can vary depending on environmental factors like ambient temperature and humidity, or things as simple as the type of paper you print on; errant fibers on recycled paper can scratch the photoconductor.

Unfortunately, access to the sheet rollers is somewhat limited. To reach them, you can remove a panel at the rear of the printer (as seen here), flip the printer on its side and reach any sheets just past the input tray (as seen here), or lift the scanner to pull out any jammed sheets that would have come out of the output tray. None of these methods makes it very easy to remove any jammed sheets, and if any were to tear, it'd be pretty hard to clear out the remaining pieces.

This printer has a small, monochrome LCD screen. It has good viewing angles, so you can see what's displayed whether you're standing, sitting, or looking at it from the side, and it responds quickly to inputs made using the buttons. Overall functionality is limited, as the printer's physical interface only allows you to change the number of copies in a print job or tweak contrast and scaling. All other settings are accessed via the HP Smart application on your computer or mobile device.

The HP LaserJet Tank MFP 2604sdw's page yield is exceptionally high. Rather than use conventional toner cartridges like normal laser printers, it has a reservoir that can be refilled with toner pouches, as seen here. It's similar in concept to supertank inkjet printers like the Epson EcoTank ET-4850. Toner top-up pouches are available in either full-yield HP 153X or half-yield HP 153A formats, which the manufacturer advertises to provide sufficient toner for 5000 or 2500 prints, respectively.

There's a little display at the front to give you an idea of how much toner is left, as seen here. When the tank is half-empty, it shows a single bar. When the tank is nearly empty, only the last remaining part of the bar indicator is illuminated. However, when the printer determines that you've run out of toner, the last portion of the bar indicator turns yellow, and the status light to its right starts flashing. You can refill the toner reservoir even during a print job.

It's important to note that the printer doesn't keep tabs on the actual amount of remaining toner and instead relies on a page counter to estimate how much toner has been used; printing won't resume until the tank has been filled at least halfway. The calibration seems to lean a little conservative on this printer; both this HP LaserJet Tank MFP 2604sdw and the similarly designed HP Neverstop Laser MFP 1202w have an advertised page yield of 5000 prints. 

However, in testing, the Neverstop MFP 1202w, which uses a slightly different drum unit and refill system, had an estimated page yield nearly twice that advertised figure. At the same time, the 2604sdw didn't reach it. Regardless, even at roughly half the estimated yield of the Neverstop, the 2604sdw's page yield is still substantial and more than sufficient for frequent high-volume printing.

The HP LaserJet Tank MFP 2604sdw printer has a flatbed scanner and an automatic document feeder. Unfortunately, it can't automatically process double-sided documents, so you must manually flip over each sheet, which may be a hassle if you have a long document to scan. Its hinges also can't be extended to accommodate thicker documents, magazines, and books.

It can also scan documents as a text-searchable PDF. It works fairly well and has little trouble with identifying plain text. However, it does have a bit of trouble recognizing special characters and accents.

The 2602dn, 2604dw, 2606dn, and 2606dw model variants of this printer lack an automatic document feeder.

The scan quality is mediocre. Scanned documents have a slightly blurry, out-of-focus appearance, colors look grainy, and fine details aren't particularly well-resolved. Scanning through the ADF with the built-in page guides, as opposed to simply laying the document flat on the scanner, results in a less blurry but slightly crooked scan, as seen here. The scanner's backing plate also does a poor job of flattening documents against the scanner bed, emphasizing minor flaws in the original document, like creases and folds.

• Power cable

Note: While the printer doesn't come with any starter toner bottles, it ships with a fully-filled toner tank.

The quality of printed black-and-white documents is superb. Fine details are well-resolved, text is crisp and highly legible, and it's fairly easy to recognize shifts from lighter to darker shades of grey.

The HP LaserJet Tank MFP 2604sdw is a monochrome printer that can't print documents in color. That said, color documents printed in black-and-white exhibit slightly less contrast than original black-and-white documents. Lighter colors converted to grayscale are harder to distinguish from darker colors converted to grayscale.

The HP LaserJet Tank MFP 2604sdw printer has an incredibly low cost-per-print. The printer itself is rather pricey, but top-ups for its toner tank are inexpensive and yield a huge number of prints. However, it's worth repeating that the drum unit isn't user-replaceable and needs to be replaced by an authorized service provider, with the repair cost varying depending on the region. Of course, given the drum unit's estimated 50,000 print-lifespan, you don't need to worry about the cost of this service too much.

The HP LaserJet Tank MFP 2604sdw's printing speed is fairly quick overall, but it can vary depending on the connection used. Printing speed on Wi-Fi tops out at 9 PPM since there's a noticeable pause between each page. Conversely, there's no significant pause when connected via USB, resulting in a much faster speed of 22 PPM, which almost falls in line with the advertised claim of 23 PPM.

It's worth noting that printing speed is evaluated by printing a 50-page document. Printing a document with fewer pages will lessen processing requirements when connected over Wi-Fi, lessening the delay between pages being outputted.

You can set custom paper sizes from 102mm x 152mm (4" x 6") to 216mm x 356mm (8.5" x 14").

The HP LaserJet Tank MFP 2604sdw is a black-and-white-only unit that doesn't print in color.

This printer is a black-and-white-only unit that doesn't print in color.

The HP LaserJet Tank MFP 2604sdw printer does a terrible job of reproducing details—the low print resolution and printing pattern completely obscure fine elements in photos.

The HP LaserJet Tank MFP 2604sdw can't print on glossy paper.

The HP LaserJet Tank MFP 2604sdw printer does have Bluetooth, but it's important to note that this is only used for device setup, and you can't print documents from devices connected over Bluetooth.

The 2602dn, 2602sdn, 2606dn, and 2606sdn model variants don't have any form of wireless connectivity.

You can print, scan, and copy using the HP Smart app from your mobile device. You can also send a mobile fax, requiring a paid HP Smart Advance subscription. You can check estimated toner levels or put in a purchase order for more toner. You can print from cloud services like Dropbox, Google Drive, Facebook, and Evernote on iOS, but only through Facebook for Android devices.

You must manually install drivers to print and scan on a Windows device. No driver installation is necessary when using macOS or Chrome OS devices. Regardless of your device's OS, you'll need to install the HP Smart app to access all of the printer's features, as the printer's physical interface offers only limited overall functionality.
