AI Verdict
A 45.4-pound all-in-one with 500-sheet capacity and 13" x 19" wide-format printing, built for high-volume office tasks.
This printer is a situational fit for businesses that specifically require wide-format printing up to 13" x 19" and high paper capacity (500 sheets) for heavy workloads. Its 45.4-pound weight and reported ink consumption make it less suitable for casual or space-constrained users.
If wide-format printing isn't a must-have, look for a printer with lower ink costs per page and a smaller footprint.

Dimension Scores
This dimension is not applicable for a printer product.
This dimension is not applicable for a printer product.
While described as "high-volume reliability" by Epson, user complaints about connectivity issues and specific scanning challenges with third-party ink suggest it's average for its category.
It's a black office machine with a 4.3" color touchscreen, but its 45.4-pound weight and large footprint mean it's not designed for sleekness or to be a space-saver.
Best For
- Small businesses needing to print large spreadsheets or design proofs up to 13" x 19".
- Offices with high-volume printing needs, supported by a 500-sheet paper capacity and 50-sheet ADF.
- Users requiring automatic 2-sided printing, copying, scanning, and faxing.
- Workspaces needing flexible connectivity options including wireless, Ethernet, and mobile printing apps.
Not Recommended For
- Home users with limited desk space, given its 45.4-pound weight and large footprint.
- Budget-conscious individuals due to reported high ink costs.
- Users who frequently print only black and white but might run out of color ink, as it can halt all printing.
Watch Out For
- The printer consumes ink rapidly; one user reported half-gone color ink levels after less than 100 sheets of text with no color use.
- Wi-Fi connection is "CONSTANTLY an issue" for some users, failing to connect repeatedly.
- At 45.4 pounds, it's not a space-saver and is described as taking up "more desk real estate than an old school HP Laser Printer".
- If any color ink runs out, the printer will not allow black and white printing, forcing users to keep color refills on hand to avoid downtime.
- Some owners report occasional scanning issues or challenges when using third-party ink.

What Buyers Say
The most surprising finding from user reviews is the recurring complaint about high ink consumption, with one user noting half-empty color cartridges after printing less than 100 text-only sheets. Many users also struggle with inconsistent Wi-Fi connectivity, describing it as "CONSTANTLY an issue". Despite these frustrations, the printer is praised for its ability to handle wide-format prints up to 13" x 19" and its overall speed for an inkjet. Its physical size and weight are frequently mentioned as drawbacks, with one owner stating it takes up "more desk real estate than an old school HP Laser Printer".
“This thing eats ink like crazy, and the Wi-Fi drops all the time, but when it actually prints those big plans, it's a lifesaver. Just wish it wasn't such a pain to keep running.”
