Epson ET-7750 printer: when EcoTank switches to A3 and thinks of the photo

Ergonomics

The Epson EcoTank ET-7750 does not have an A3 scanner. It just prints in this format, via a dedicated paper entry on the back of its chassis, like the Epson XP-960. A subtlety which allows this model to keep approximately acceptable measurements, although it is still an imposing black block of 52.6 x 41.5 x 16.8 cm, for 10.5 kg. Fortunately, it is equipped with Wi-Fi (Wi-Fi Direct and Cloud Print compatible), which will allow it to be installed almost anywhere in your home and not necessarily near the office. However, it can also be connected via USB and Ethernet.

This printer is extremely simple to understand and very complete. His only small mistake is to have a small non-touch color LCD screen. But given the small size of this screen (6.8 cm diagonal), however, it makes the right choice in our opinion to prefer a control panel fully controllable using traditional buttons. This certainly has the disadvantage of visually cluttering the front, but all the settings and operations are done without the slightest clash, the menus being perfectly clear and legible.

In addition to a rear feeder which supports sheets up to A3 format therefore, the paper supply is made via a double front cassette, very practical for having two types of paper permanently available: typically, sheets Plain A4 (100-sheet capacity) and 10 x 15 cm envelopes or photo paper (20-sheet capacity). Also note the presence of a printing cart for optical media, as well as a USB host port and an SD card reader, signs of a product with all options that also supports automatic duplex printing. . A hatch could not be more easily accessible also allows, at the rear, to intervene in the event of paper jam.

Finally, the first installation of the printer - guided by the manual - allows a better understanding of the functioning of an EcoTank model. Here, no ink cartridge to clip on the motorized cart. Instead, five tanks to be filled on the right side of the printer with the appropriate inks delivered in small canisters. The print heads used are of the Micro Piezo type, with 360 nozzles for black and 180 nozzles per color. The printer works with a variable point size, the drops being at least 1.5 picoliter.

Consumption

In terms of power consumption, the EcoTank ET-7750 is slightly more economical than a photo-oriented inkjet multifunction printer like the XP-960 from the same manufacturer. It is indeed content with 0.7 W in standby mode and 15 W when printing a photo in A4 format.

The noise pollution it causes when printing is fairly standard: up to 60.8 dB when printing an office document of several pages and 47.7 dB when printing a photo. A "silent" mode is available; once activated, it lowers emissions in office printing around 57.6 dB, slightly reducing the bit rates observed. On this point, the Expression Photo XP-960 was much more discreet (39.6 dB in standard office printing).

Cost per page

As we know, the printers in the EcoTank range are unbeatable in terms of cost per page. This is once again the case here, thanks to replacement ink bottles charged at low prices: around € 15 for black, € 10 for colors and € 10 also for photo black, for respective yields of 8,000, 5,000 and 1,900 pages. We thus benefit from a cost per page of only 0.2 euro cent (0.002 €) in black and white, and 1.3 euro cent (0.013 €) in color.

We can quibble by recalling that other references of EcoTank printers reach an average cost per page of 0.6 euro cents (including the EcoTank ET-4750), but the fact remains that it is extremely low, all the more so for a printer that can suit photo enthusiasts. With its most economical XL cartridges, the XP-960 does worse (16.6 euro cents per page on average). Over time, the investment required in ink will not be the same at all. On the other hand, the purchase price of the printer here varies from simple to triple.

Scanner and copies

The Epson ET-7750 is not equipped with the fastest flatbed scanner on the market, but it defends itself well in the areas of copying and scanning. It takes 14 seconds to scan an A4 document at 100 dpi, and 12 seconds to do the same with a 10 x 15 cm photo at 300 dpi. The quality of the copies (which require on average 10 s in black and white and 22 s in color) is again standard: the copies are perfectly legible, but slightly washed out.

Photo

Unlike the EcoTank ET-4750, versatile but more productivity-oriented, this ET-7750 uses printheads capable of applying smaller drops of ink to paper and works with an ink that improves its rendering Photo. In photo printing, the result obtained is quite good. On the one hand, the average color drift measured is fairly correct for a product in this category (Delta E of 6.8, identical to that of a photo-oriented XP-960). On the other hand, the fine print gives the images a good sharpness, for an excellent result with the naked eye.

However, this model is not the fastest to get its shots out. Allow 52 s to shoot a photo in 10 x 15 cm format and 1 min 25 for a photo in A4 format. This remains acceptable, especially since photo printing is an area in which we will often prefer to wait a few seconds longer for a better result. The printing of an A3 photo is relatively long, but it is often the case: here, on our test image, we note 4 min and 12 s.

Office

In accordance with the ISO standard, Epson claims that this EcoTank ET-7750 is capable of holding print speeds of up to 13 and 10 pages per minute (ppm) on plain paper, respectively in black and white and in color. The brand completes this information with internal tests, suggesting a speed of up to 28 ppm. Our laboratory measurements place the printer roughly between these values, since on our reference documents, we find flow rates around 19.4 ppm in black and white and 17.1 ppm in color. Given the positioning of this printer, it's pretty good; flow rates are better than those measured on an ET-4750, for example. In automatic duplexing, bit rates drop to 6.7 ppm in black and white.

As for the results obtained, they are good. Without achieving the precision of laser printers in this area, we take advantage of sufficiently precise texts and an appreciable rendering on graphics, gradations and solid colors, as evidenced by our high resolution scans magnified about three times. Nevertheless, the latest EcoTanks - including this ET-7750 - still have a little room for improvement in office automation to deliver small characters that are a little sharper, including on a colored background.

Conclusion

The only real complaint we have about the EcoTank ET-7750 is its selling price, which will deter more than one. However, this multifunction inkjet printer has it all, especially if you print a lot of photos. Take advantage of such a low cost per page on such a versatile product, which can print in A3, it is indeed terribly tempting.
