1. General information
The Lexmark™ 7100 Series (4409-XXX) All-In-One features an
electro-mechanical color scanner, printer, copier, and fax that
creates characters and graphics by composing programmed
patterns of ink dots using a printhead and liquid ink. The printhead
uses small heater plates and nozzles to control ink flow and the
formation of characters on the print media. The printhead assembly
and ink supply are combined into a single-unit print cartridge
available as a customer replaceable supply item. Dual printheads
provide color and true black printing without changing printheads.
The number and size of inkjets or nozzles in the printhead
determines the overall quality and capability of the printer. The black
cartridge has a total of 640 nozzles and installs on the left. The color
cartridge has a total of 480 nozzles installs on the right. The printer
is capable of printing in two directions from either cartridge.

Speed Dials
(5—99)
This button gives access to additional speed dial
numbers. Speed dials #5—#79 are single entry and
speed dials #80—#99 are group entries. Single entries
contain only one phone number. Group entries contain
up to five different phone numbers. The speed dial
names and numbers can be programmed by using
either the control panel or the host software.
Pressing this button displays the speed dial #5 and
upward name and phone number. You can cycle
through the speed dial in multiple ways:
1. Repeated pressing of Speed Dials (5—99) button
2. Using the arrow keys
3. Using the keypad to type the two digit number
Pressing the speed dials (5—99) button while in the

mode and display speed dial selection #5.
Redial/Pause When pressing this button while the machine is in fax
mode, the machine will immediately dial the number
that was last entered. The fax is sent using the current
settings.
Pressing this button after you have already started
entering a number inserts a “,” into the number. When
the machine dials this number, the “,” results in a three
second pause before sending the next number. This is
useful if needing to wait for an outside line or waiting
for prompts in an automated answering system.
If this button is pressed while in copy or scan mode,
the machine will automatically switch to fax mode and
initiate the proper response for redial/pause.

the failure.
After you complete the repair, perform tests as needed to verify the
repair.
Auto Answer Toggles the state of the auto answer function and the
auto answer LED.
