Lexmark X792 Manual

							MAKE SURE THE CORRECT PRINTER SOFTWARE IS INSTALLED
Verify that you are using the correct printer software.
If the printer is connected to your computer through a USB port, then make sure you are running a supported
operating system and using a compatible printer software.
MAKE SURE THE INTERNAL PRINT SERVER IS WORKING PROPERLY
Make sure the internal print server is properly installed and that the printer is connected to the network.
Print a network setup page and check that the status shows Connected. If the status is Not Connected,
then check the network cables, and then try printing the network setup page again. Contact your system support
person to make sure the network is functioning correctly.
The printer software is available on the Lexmark Web site at 
http://support.lexmark.com.
MAKE SURE YOU ARE USING A RECOMMENDED USB, SERIAL, OR ETHERNET CABLE
For more information, visit the Lexmark Web site at http://support.lexmark.com.
MAKE SURE PRINTER CABLES ARE SECURELY CONNECTED
Check the cable connections to the printer and print server to make sure they are secure.
For more information, see the setup documentation that came with the printer.
Confidential and other held jobs do not print
These are possible solutions. Try one or more of the following:
PARTIAL JOB, NO JOB, OR BLANK PAGE PRINTS
The print job may contain a formatting error or invalid data.
Delete the print job, and then print it again.
For PDF documents, recreate the PDF and then print it again.
If you are printing from the Internet, then the printer may be reading multiple job titles as duplicates and deleting
all jobs except the first one.
For Windows users, open Print Properties. From the Print and Hold dialog, select the Keep duplicate documents
check box under the User name text box before entering a PIN number.
For Macintosh users, save each print job, naming each job differently, and then send the individual jobs to the
printer.
MAKE SURE THE PRINTER HAS SUFFICIENT MEMORY
Free up additional printer memory by scrolling through the list of held jobs and deleting some of them. Troubleshooting261 
						

							Print job takes longer than expected
Try one or more of the following:
REDUCE THE COMPLEXITY OF THE PRINT JOB
Eliminate the number and size of fonts, the number and complexity of images, and the number of pages in the print
job.
TURN OFF THE PAGE PROTECT SETTING
From the home screen, navigate to:
 > Settings > General Settings > Print Recovery > Page Protect > Off >

5If you hear a dial tone, then connect the printer to that wall jack.
REVIEW THIS DIGITAL PHONE SERVICE CHECKLIST
The fax modem is an analog device. Certain devices can be connected to the printer so that digital telephone services
can be used.
If you are using an ISDN telephone service, then connect the printer to an analog telephone port (an R-interface
port) on an ISDN terminal adapter. For more information and to request an R-interface port, contact your ISDN
provider.
If you are using DSL, then connect to a DSL filter or router that will support analog use. For more information,
contact your DSL provider.
If you are using a PBX telephone service, then make sure you are connecting to an analog connection on the PBX.
If none exists, consider installing an analog telephone line for the fax machine.
CHECK FOR A DIAL TONE
Pl a c e  a  te s t c a l l  to  t h e  t e l e p h o n e  n u m b e r t o w h i c h  y o u  w a n t to  se n d  a  f a x  t o m a k e  su re  t h a t  i t i s  w or k i n g c o r re c tl y .
If the telephone line is being used by another device, then wait until the other device is finished before sending
a fax.
If you are using the On Hook Dial feature, then turn up the volume to verify a dial tone. Troubleshooting269 
						

							TEMPORARILY DISCONNECT OTHER EQUIPMENT
To ensure the printer is working correctly, connect it directly to the telephone line. Disconnect any answering
machines, computers with modems, or telephone line splitters.
