ENUS25663Overview
This article explains the limit to the number of shortcuts that you can create for each type of function – Fax, Email, and File Transfer Protocol (FTP) – on the Lexmark MFPs listed below.
Memory Options and Allocation for MFPs 2007 and Below
These Lexmark MFPs base the number of shortcuts available on memory requirements, not on a hard limit to the number of shortcuts.
Example using Fax shortcuts:
One shortcut for each (ten-digit number = 123-456-7890) (16-character name = John Doe’s Fax) = 31 bytes per entry
Disk Model 56,350 bytes | 56,350/31 = 1817 speed dials (or 1800 to round off the number) |
Non-Disk Model 16,100 bytes | 16,100/31 = 519 speed dials (or 500 to round off the number) |
X642e and X644e (non-disk) support:
- Fax = 16,100 bytes
- Email = 16,100 bytes
- FTP = 8,000 bytes
- Profiles = 100 total or 16,384 bytes, whichever comes first.
NOTE: On MFPs with a hard disk, there is 3.5 times as much space as on a non-disk model.
The X646e, X64xef, and X85xe (with hard disk) support:
- Fax = 56,350 bytes
- Email = 56,350 bytes
- FTP = 28,000 bytes
- Profiles = 100 total or 16,384 bytes, whichever comes first.
NOTE: An x denotes any number within a given model series.
Memory Options and Allocation for MFPs 2008 Onwards
The maximum number of shortcuts that can be created for the following functions – Fax, Email, File Transfer Protocol (FTP), Copy, and Profiles – is based on two criteria:

Memory requirements
NOTE: The presence of a hard drive or other memory options does NOT affect the memory available for shortcut storage.

The total number of Fax + Email + FTP shortcuts is limited to 500 entries (not 500 of each type).IMPORTANT! Either limit being reached will prevent additional shortcuts from being installed.
X20x, X36x, X54x Series MFPs:
- Fax Shortcuts (Speed Dials) = A maximum of approximately 99 based on a ten digit phone number
- Locations in a shortcut = A maximum of 12 locations
- Numbers of characters = A maximum of 512 characters
