Kyocera M3550idn Default Password Work May 2026
In later production runs of the M3550idn, Kyocera attached a small white sticker with a barcode inside the front cover or on the back near the network port. This sticker says “Default Password” followed by a 6- to 12-character alphanumeric string (e.g., KJM3P9L2).
How to find it:
Use that unique password with the username Admin. This is the most reliable “default password work” solution for newer units.
The M3550idn shines in its scanning capabilities. Using the web interface, you can input email addresses and SMB folder paths so users can scan documents directly to their desktops or inboxes with one touch on the physical screen. This saves immense amounts of time for the whole office.
If the default password isn’t working, here is a systematic approach to regain access.
Before troubleshooting, let’s confirm the factory settings. When the Kyocera M3550idn leaves the factory, it ships with the following default login credentials:
| Field | Default Value |
| :--- | :--- |
| Login User Name | Admin (Case-sensitive: capital "A") |
| Default Password | Admin (Older firmware) OR admin (Newer firmware) |
Note: On very early M3550idn models (firmware v1.0), the password was often blank or simply Admin. However, due to cybersecurity requirements, Kyocera shifted to admin (lowercase) and later to a unique password printed on a label.
The Default Password Conundrum
John had been the IT administrator at XYZ Corporation for over five years. He had seen it all - from faulty network cables to malfunctioning servers. But on this particular day, he was faced with a seemingly simple task: setting up a new printer.
The printer in question was a Kyocera M3550idn, a multifunctional device that could print, scan, and fax. John had unboxed it, connected it to the network, and was now ready to configure it for use by the entire office.
As he began to navigate the printer's menu, he realized that he needed to access the administrator settings to configure the device's network settings and set up user authentication. But, to his surprise, he couldn't find the administrator password.
The manual didn't provide a clear answer, and a quick online search didn't yield any results. John tried the usual suspects - "admin," "password," "123456" - but none of them worked.
Just as he was about to give up, John stumbled upon a Kyocera support page that mentioned the default password for the M3550idn. According to the page, the default administrator password was... "7654321".
John was skeptical, but he decided to give it a try. He entered the password, and to his surprise, it worked! He was now able to access the administrator settings and configure the printer as needed.
With the printer set up and configured, John couldn't help but feel a sense of satisfaction. He had overcome a minor obstacle and ensured that the office would have a reliable and secure printing solution.
But as he was about to leave his desk, he received a call from a colleague. "Hey John, I heard you struggled with the printer's password," his colleague said with a chuckle. "Just a heads up - the default password for the M3550idn is indeed '7654321'. You might want to update our company's knowledge base with that info."
John smiled, realizing that his experience would help others in the future. He made a mental note to update the company's documentation and share his findings with the IT team. kyocera m3550idn default password work
From that day on, John made sure to keep track of default passwords for all devices, including the Kyocera M3550idn. And whenever someone asked him about the default password, he would smile and say, "It's 7654321, my friend!"
