I'm sorry about the issue. Please try the following:
- Download the printer driver at the Lexmark website below:
, then open the download file X5400Series_Print_1.0.0_10.6orLater_forIntel.dmg to install it. (Just allow it to install.)
, next, make sure the printer is powered on and connected to the computer (with a USB printer cable)
, then click on the Apple logo / menu at the top, then click on System Preferences, then open Printers & Scanners (or Print & Fax), then click on the + (plus) icon at bottom left, then it should detect your Lexmark printer, then add it
, then check printing.
- That should work, but if needed, download and install the Lexmark Printer Driver 3.1 at the Apple website below:
, (and/or click on the Apple logo / menu at the top, then click on App Store, then click on Update, and install any Lexmark item there)
; if needed, do STEP 2 again.
When you are available, please reply at the box below to continue. Thank you.
