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.
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
