General Information

This manual is used to service the Lexmark Medley 4012. Medley is
a multifunction product which can connect to an IBM-compatible per-
sonal computer. It acts as an all-in-one color-capable printer, G3 fax
machine, scanner, and convenience copier. It will send and receive
faxes, scan documents, print from the PC, and make convenience
copies. It uses 300 x 300 pels per inch inkjet technology for high
quality text and graphics. Print Quality Enhancement Technology
(PQET) smooths the edges of lines and characters.
Medley uses the same black or color print cartridges as the IBM
ExecJet II and ExecJet IIc by Lexmark.
Medley uses a 300 x 300 dpi scanner for fast, high quality scanning,
personal copying, and faxing. Scanning software for the PC is
included with the Medley.
There are three models: Medley 4c (4012-005) which does not
include a handset, Medley 4x (4012-006) which does include a
handset, and the Medley 4sx (4012-009) which is the same as the
4x but is shipped standard with the battery backup. Other than in the
Parts Catalog, there are no service differences.
All models can handle a variety of paper sizes as well as envelopes
and other media using an integrated automatic sheet feed and man-
ual feed.
The machine contains the following circuit boards:
•
Fax Board—controls the scanner and most of the machine's
functions
•
Printer Board—runs the printer motors, sensors, and printhead
•
Line Connect Unit (LCU) Board—printer parallel port and tele-
phone connections
•
Operator Panel Board
