According to reviewers on Amazon.com, common problems with the Lexmark X5650 All-in-One Inkjet Printer and the Lexmark Z1420 Inkjet Printer include that the fax and scan features don’t work properly and the printer turns off while printing. Another problem with Lexmark printers is slow printing speed.
One customer notes that she often needs to uninstall and reinstall the printer due to connection issues when faxing and scanning. Another buyer complains that the printer is extremely slow and the print quality is inconsistent. An unhappy reviewer states that the Wi-Fi connection doesn’t work, even after updating firmware, and another customer notes that the Lexmark printer says the drivers are not installed, even though all the drivers from the Lexmark website have been installed.
