Smart Card Authentication

Using Caps-lock to Enter Non-Alphanumeric Characters or Password Results in a Login Failure with the Lexmark MX711 or Similar MFPs

What you will see

Engaging the Caps-lock button no longer allows entry of a non-alphanumeric password and results in an Authentication failed message when you attempt to manually log into the MFP. This is occurring on SCAC-enabled MFPs with badge readers.

Affected products

This issue was first identified on a Lexmark MX711 MFP; however, any device with a 7" inch display with firmware (FW) LW61.xx7.P643, or later, will behave in a similar fashion. See xref_H0550_xref if unsure how to determine your device's firmware version.

Explanation and suggested remedies

This original design was modified starting with EC6 (.P643) due to concerns over security vulnerabilities. Login with your badge (smart card), or use the Shift button instead of Caps-lock to enter non-alphanumeric characters
