Limited Time to Enter the Fax Shortcut Key when Using the Keypad in the Fax Menu

What you will see

A “Could not find shortcut #...” message displays on the control panel while you enter the shortcut code via the printer’s KEYPAD in the Fax menu.

It works when pressing the # key directly while on the main screen and entering the code (e.g., five-digit shortcut) or using the TOUCH SCREENnumeric pad while in the Fax menu.

See sample videos below.

Affected printers

This issue applies to the following Lexmark models, but other models not listed here could be affected:

  • CX410
  • CX510
  • MX310
  • MX410
  • MX51x
  • MX61x
  • MX71x
  • MX81x

An x denotes any number within a given printer model series.


It appears that you are only given about two to four seconds to enter the entire fax shortcut code; thus, the printer search result comes up with an error due to an incomplete code.

Recommended action

Update the printer’s firmware to PE Release code P452 or higher.

To obtain this version, please contact Lexmark Technical Support and reference this article ID. Support personnel can assist you with the update procedure if necessary.
