Applications and Processes


NOTE:  Most of these processes talk to the Lexmark Communication System (LCS), which handles all traffic to and from the printer. The applications use TCP/IP to talk to the LCS, which may trigger some firewall software. The TCP port used for communication between application varies by product.

Process <prefix> Function
Instgui.exe Installation software
<prefix>coms.exe Lexmark Communication System – This process handles low-level communication between the PC and the device over USB and networked connections. This uses TCP/IP and UDP/IP to talk to network printers.
<prefix>wbgw.exe This process communicates with the Internet. This is the only Lexmark SW component that communicates with the Internet.
<prefix>lscn.exe Lean scan
<prefix>pswx.exe Handles printing status and posts alerts (e.g., Paper Out, Ink Low). Also the Lexmark Solution Center application.
<prefix>time.exe Lexmark Connect
<prefix>mon.exe Device Monitor This listens for button presses from the device for operator panel-initiated scanning. The system tray has an icon for the Lexmark All-in-One Center or Lexmark Imaging Studio. This application displays that icon.
<prefix>jswx.exe Job Status Window – Shows job progress bar.
<prefix>aiox.exe

All-in-One Center – Shipped on Lexmark products prior to 2007.

<prefix>fax.exe Fax Software
<prefix>wpss.exe The Wireless Setup utility allows easy configuration of the printer's wireless settings from the PC and communicates over the local network.
<prefix>app4r.exe Lexmark Imaging Studio – Started shipping on Lexmark products in 2007.

 

Prefixes


Prefix
is a product unique value which differs by individual All-In-One or inkjet model. For example, <lxdj>pswx.exe contains the prefix <lxdj> which references a Lexmark Z1420 inkjet printer.

HINT: If unsure about your printer model's prefix, perform a search on lx*.* using Microsoft's search tool.

Model-specific prefixes:

2011 onwards – No <lx??> devices but still with <prefixes>

<LMADE>: S310 Series
<LMADG>: S410 Series
<LMADH>: S510 Series
<LMADI>: Pro710 Series
<LMADJ>: Pro910 Series
<LMADK>: Pro4000 Series
<LMADL>: Pro5500 Series
Common prefixes: <LM>, <lex>

2009-2010

<lxea>: S300 series and S400 series 
<lxeb>: Pro200 series and S500 series
<lxed>: S600 series
<lxee>: Pro700 series
<lxec>: Pro800 series and Pro900 series

2008 and below

<lxd?>
<lxc?>
<lx??>

NOTE: <lx??> – The question mark will be replaced by a character representing the model printer that you have. There will be only one entry unless you have multiple Lexmark printers installed.
