Epson L3550 Specifications
The Epson L3550 is an EcoTank A4 multifunction inkjet with print, scan, and copy functions, while fax is outside the hardware set. Printing relies on a PrecisionCore printhead with 400 black nozzles and 128 nozzles for each colour. Four refillable tanks take dye ink in black, cyan, yellow, and magenta. Local control stays button-based rather than touchscreen-based, which matches its compact Home-series layout.
Maximum print resolution reaches 4,800 x 1,200 dpi, and the smallest droplet size is 3.3 pl with variable-sized droplet technology. ISO speed runs at 15 ppm in monochrome and 8 ppm in colour. Draft output reaches 33 ppm in black and 20 ppm in colour on plain paper. First-page output is about 9 seconds in mono and 15 seconds in colour. Scanning uses a CIS flatbed at 1,200 x 2,400 dpi.
Paper input comes through one rear tray with a 100-sheet capacity, while the output tray holds 30 sheets. Manual duplex printing is listed, so two-sided pages need turning by hand. Paper sizes cover A4, A5, A6, B5, B6, Letter, Legal, 10 x 15 cm, 13 x 18 cm, DL envelopes, C6 envelopes, and Number 10 envelopes. Borderless printing reaches 10 x 15 cm.
Connectivity covers Hi-Speed USB, Wi-Fi, Wi-Fi Direct, and Epson Connect services such as Epson iPrint, Email Print, and Remote Print Driver. Wired networking is limited because Ethernet is not part of this hardware. Closed dimensions are 375 x 347 x 179 mm, and the product weight is 4.1 kg. Power use is about 12 W during standalone copying, 7.1 W in ready mode, and 0.2 W when powered off.
