Multiple symptoms may indicate a

firewall

is preventing communication.

You should eliminate other communication issues as a possible root cause for the symptoms described above.

First, if one function is failing you should always try another printer/scanner function to test communication.

For example

If...	Then...
You cannot print, but you are able to scan...	Proceed to Suggested Remedy . It is important to understand that other print queue-related issues are possible.
You cannot scan, but you are able to print...	Proceed to Suggested Remedy .
You cannot scan or print...	You should see Additional Actions to further validate printer-to-pc communication before proceeding to Suggested Remedy .

Action...	Purpose...
1. Identify status " Connected " on the network setup (settings) page? To do this from the operator panel: Press or equivalent Setup/Menus button on the printer operator panel. Navigate to Reports . Navigate to Network Setup Page and select it. Navigate to Print Setup Page and select it.	A status of ' connected ' indicates the printer is communicating on a network; however, it does not necessarily prove that it is communicating on your network.
2. Access the printer's web page. To do this: Obtain the IP Address off of the network setup page. Enter the printer's IP address into your Web browser's address field; e.g., http:// Printer_IP_Address , where Printer_IP_Address is your printer's TCP/IP address.	This guarantees that your printer is communicating with your PC.

It is possible that a scan function is not working because the process utilized by one of the printer functions is blocked.

Step 1:

Identify you firewall application.

Step 2:

I dentify any blocked processes that begin with

LM

or

LEX

.

Step 3:

Grant access or create an exceptionfor the process and a

Microsoft™ Windows 7 Firewall Example

Identify your firewall application and identify where you can make changes to your firewall protection settings.

IMPORTANT!

This is where you will create exceptions for processes that are listed in the next step below.

Here is a list of possible firewall types, listed from the most common to least common found on PC:

Now that you have identified your firewall application and where you create exceptions for blocked processes, you will want to use the table below to identify whether a blocked process is visible.

Be aware of your printer model's prefix for the

lscn

.exe and

mon

.exe processes.

Model-specific

prefixes, to include:

Common

prefixes: <

LM

>, <

lex

>

For example,

LMACT

mon.exe contains the prefix <

LMACS

> which references a

Lexmark

X792

printer.

Process < PREFIX > - lxcq	Function	Possible error/symptom if process blocked
<prefix> lscn .exe Lean Scan	Required for successful Scan Profile communication. For example, if you press Scan > Scan Profile ...	Computer Connection Error is displayed on the printer.
<prefix> mon .exe Device Monitor	This listens for button presses from the device for operator panel-initiated scanning . For example, if you press Scan > Computer ...	No response when you press , or a Computer Connection Error displays on the printer.
LM smc .exe/ lmab1err.exe (All Models) Status Monitor Center Status Messenger in Windows	The Status Monitor Center controls: Supplies alerts Error message logs Problem resolutions in certain situations	Logs and printer notifications will not be displayed.
LM psu.exe (All Models) Printer Setup Utility	Allows for the configuration of printer fax settings and address book settings. Lexmark Printer Setup Utility or Fax Setup Wizard utilizes this process.	Unable to add/edit contacts or change settings on the printer from either of these utilities
LM wpss.exe (All Models) Wireless Print Server Setup Utility	Necessary for the successful configuration your wireless printer. Lexmark Wireless Setup Utility requires this process.	Gray Continue button and the inability to configure wireless configuration parameters on the printer
(All Models) lex twprotocol.dll, lex networkds.ds LM abscw.dll LM abmini.dll LM abtwds.ds LM abtwpro.dll LM abtwui.dll LM abdrs.dll LM abdrs64.dll LM zzz_32__bc.dll LM zzz_32serv.dll	These associated local/ network TWAIN files require a network TWAIN compliant application to use them...	If the application that uses these files is blocked by a firewall, then these are files are blocked by association. Make sure your scanning software (.exe) is not blocked by a firewall.
LM pssu print server setup utility	The print server setup utility provides a secondary method for first-time printer configuration of static IP parameters.	The utility is unable to find the printer or you receive a message that the utility is unable to find the printer. Note: This utility does require the host PC be on the same subnet as the printer.
scanwiz.exe (All Models) scanback utility	The scanback utility requires this process to assure a network communication path for scanback generated scan-to-pc profiles.	Any created shortcut (profile) utilizing this utility will fail, or in some instances you will not even be able to create the profile depending on your firewall security level.

You have now identified the blocked process in your firewall application. You will now need to grant permissions in your firewall application to allow these processes to communicate over the network .

IM

PORTANT!

You need to know where your firewall software allows you to grant exceptions or permissions.

NOTE:

All firewall manufactures use slightly different terminology to reference this permission granting process; e.g.,

Permit Always

,

Allow Full Access

,

Allow

, etc.

for some examples, but reference this article for the process names listed above.

If you receive a

Windows Security Alert

, make sure you select

Allow access

for any

LM

process:

If you do not allow access for all

LM

and

LEX

processes, you may need to follow the procedure similar to this one.
