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.

copies. Upon entering this mode, the LCD shall display

the current number of copies, the copy quality, and the

reduce/enlarge percentage. To make a copy, enter the

copy mode and press either Color or Mono to initiate

the copy.

Fax Mode: This mode is used to transmit faxes. Upon

entering this mode, the LCD shall prompt the user for a

phone number to initiate a fax, and the display will

show the current date and time. To initiate a fax, enter

the fax mode, enter a phone number, and press either

Color or Mono to initiate the fax.

Scan Mode: Scans an image to the host. Upon

Speed Dials There are five speed dial buttons. Pressing one of

these buttons causes the machine to instantly display

the name and phone number associated with that

quick dial button. Press either the Color or Mono

button to initiate the fax to that number. The speed dial

names and numbers can be programmed by using the

control panel or the host software. Pressing one of the

speed dial buttons while in the copy or scan mode will

automatically switch to fax mode and display the first

speed dial selection.

Buttons Functions

General information 1-7

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

copy or scan mode will automatically switch to fax

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.

Maintenance approach

The diagnostic information in this manual leads you to the correct

field replaceable unit (FRU) or part. Use the symptom tables, service

checks, and diagnostic aids to determine the symptom and repair

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.

If an incoming call is present and:

• Auto answer LED is off: The machine will display the

manual mode answering message “Incoming Call

Press 9 to answer” and answer the incoming call

only if you enter the correct manual mode keypress.

• Auto answer LED is on: The machine will answer

the incoming call after the expected number of rings.

If you pick up the phone prior to the machine

answering the call and fax tones are present on the

line, it will detect these fax tones and immediately

respond to the fax.
