7.2 Troubleshooting Checklist
If the printer is not working properly, consult the following checklist. If the printer does not pass a step, follow the corresponding troubleshooting suggestions. Status Make sure that the Status LED on the control panel green and "Ready" is shown on the Smart Panel program window. Print a demo page to verify that the printer is feeding paper correctly. Check the demo page to see if it is printed correctly. Print a short document from a software application to verify that the computer and printer are connected and communicating correctly. Response If the Status LED is off, check the power cord connection. Check the power switch. Check the power source by plugging the power cord into another outlet. If the Status LED blinks or lights red, solve the problems. If a demo page does not print, check the paper supply in the paper tray. If the paper jams in the printer, go to "Clearing Paper Jams" If there is a print quality problem, go to "Solving Print Quality Problems"
If the page does not print, check the cable connection between the printer and the computer. Check the print queue or print spooler to see if the printer has been paused. Check the software application to ensure that you are using the proper printer driver and communication port. If the page is interrupted during printing, go to "Solving General Printing Problems" See "Solving General Printing Problems" See "Solving Print Quality Problems" See "Common Windows Problems" See "Common Macintosh Problems" See "Common Linux Problems"
If completing the checklist does not resolve the printer problem, check the following troubleshooting sections.

7.4 Solving Print Quality Problems
Dirt inside of the printer or improper paper loading may reduce print quality. See the table below to troubleshoot problems. Problem Solution If a vertical white streak or faded area appears on the page: The toner supply is low. You may be able to temporarily extend the toner cartridge life. If this does not improve print quality, install a new toner cartridge. The paper may not meet paper specifications (for example, the paper is too moist or too rough). A combination of faded or smeared defects may indicate that the printer needs cleaning.

Problem
Solution If the amount of background shading becomes unacceptable, the procedures below may fix the problem. Change to lighter weight paper. heck the printer's environment; very dry (low humidity) or high humidity (higher than 80% RH) conditions can increase the amount of background shading. Remove one of the old toner cartridges and install a new one.

If marks repeatedly appear on the printed side of the page at even intervals: Clean the inside of the printer. After cleaning the inside of the printer, if you still have the same problems, install a new toner cartridge of the problem color. Parts of the printer may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after a few more pages. The fusing assembly may be damaged. Contact a service representative.

Misformed characters
7-8 Service Manual
Background scatter results from bits of toner distributed on the printed page. The paper may be too damp. Try printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture. If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams on the reverse side. Printing on seams can cause problems. If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or via the printer properties window.
If characters are improperly formed and producing hollowed images, the paper stock may be too slick. Try a different paper. If characters are improperly formed and producing a wavy effect, the printer may need service. Verify that it also occurs on a demo page.

7.5 Common Windows Problems
Problem "File in Use" message appears during installation. "Error Writing to LPTx" message appears. Possible Cause and Solution Exit all software applications. Remove all software from the StartUp Group, then restart Windows. Reinstall the printer driver. Ensure that all cables are connected correctly and the printer is on. If bi-directional communication is not turned on in the driver, it will also cause this message. Close all other applications, reboot Windows and try printing again.
"General Protection Fault", "Exception OE", "Spool32", or "Illegal Operation" messages appear. "Fail To Print", "A printer timeout error occurred." messages appear.
These messages may appear during printing. Just keep waiting until the printer finishes printing. If the message appears in standby mode or after printing has been completed, check the connection and/or whether an error has occurred.
NOTE: Refer to the Microsoft Windows 98/Me/NT 4.0/2000/2003/XP User's Guide that came with your PC for further information on Windows error messages.
7.6 Common Macintosh Problems
Problem The printer does not print a document from Acrobat Reader. The document has printed, but the print job has not disappeared from the spooler in Mac OS 10.3.2. Possible Cause and Solution You should change the Print Method option to Print as Image when you print from Acrobat Reader. Update your Mac OS to OS 10.3.3 or higher.

7.7 Common Linux Problems
Problem I can't change settings in the configuration tool. I am using the KDE desktop but the configuration tool and LLPR won't start. Possible Cause and Solution You need to have administrator privileges to be able to change global settings. You may not have the GTK libraries installed. These usually come with most Linux distributions, but you may have to install them manually. Refer to your distribution's installation manual for more details about installing additional packages. Some versions of the KDE or GNOME desktop environments may require that you restart your session for the changes to take effect.
I just installed this package but can't find entries in the KDE/ Gnome menus. I get a "Some options are not selected" error message while editing the printer settings.
Some printers have conflicting settings, meaning that some settings for two options can't be selected at the same time. When you change a setting and the Printer Package detects such a conflict, the conflicting option is changed to a "No Choice" value. You have to choose an option that does not conflict before being able to submit the changes. In some conditions, it may not be possible to change the default queue. This happens with some variants of LPRng, especially on recent RedHat systems that use the "printconf" database of queues. When using printconf, the /etc./printcap file is automatically refreshed from the database of printers managed by the system (usually through the "printtool" command), and the queues in /etc./printcap.local are appended to the resulting file. The default queue in LPRng is defined as the first queue in /etc./printcap, and therefore it is not possible for the Linux Printer Package to change the default when some queues have otherwise been defined using printtool. LPD systems identify the default queue as the one named "lp". Thus, if there is already a queue by this name, and if it doesn't have an alias, then you won't be able to change the default. To work around this, you can either delete the queue or rename it by manually editing the /etc./printcap file. The N-up feature is achieved through post-processing of the PostScript data that is sent to the printing system. However, such post-processing can only be adequately achieved if the PostScript data conforms to the Adobe Document Structing Conventions. Problems may arise when using N-up and other features that rely on post-processing if the document being printed isn't compliant. Legacy BSD lpr systems have a hard limitation on the length of the option string that can be passed to the printing system. As such, if you selected a number of different options, you may have exceeded the length of the options and some of your choices won't be passed to the programs responsible for implementing them. Try to select fewer options that deviate from the defaults, to save on memory usage.
I can't make a printer the system default.
The N-up setting does not work correctly for some of my documents.
I am using BSD lpr (Slackware, Debian, older distributions) and some options chosen in LLPR don't seem to take effect.

Problem I am trying to print a document in Landscape mode, but it prints rotated and cropped.
Possible Cause and Solution Most Unix applications that offer a Landscape orientation option in their printing options will generate correct PostScript code that should be printed as is. In that case, you need to make sure that you leave the LLPR option set to its default Portrait setting, to avoid unwanted rotations of the page that would result in cropped output. If the data being sent is in Encapsulated PostScript (EPS) format, some earlier versions of CUPS (1.1.10 and before) have a bug preventing them from being processed correctly. When going through LLPR to print, the Printer Package will work around this issue by converting the data to regular PostScript. However, if your application bypasses LLPR and feeds EPS data to CUPS, the document may not print correctly. To be able to configure and use SMB-shared printers (such as printers shared on a Windows printer), you need to have a correct installation of the SAMBA package that enables that feature. The "smbclient" command should be available and usable on your system. Most Unix applications will expect a command like the regular "lpr" command to be non-interactive and thus return immediately. Since LLPR is waiting for user input before passing the job on to the print spooler, very often the application will wait for the process to return, and thus will appear to be frozen (its windows won't refresh). This is normal and the application should resume functioning correctly after the user exits LLPR. It can be specified in the "Add Printer" dialogue of the configuration tool, if you don't use the CUPS printing system. Unfortunately, CUPS currently doesn't allow you to specify the IP address of SMB printers, so you will have to be able to browse the resource with SAMBA in order to be able to print. Some versions of CUPS, especially those shipped with Mandrake Linux before the 8.1 release, have some known bugs when processing PostScript output from some applications. Try upgrading to the latest version of CUPS (at least 1.1.14). Some RPM packages for the most popular distributions are provided as a convenience with this Linux Printing Package. There may be some local options defined in your ~/ .lpoptions file, which are manipulated by the lpoptions command. These options are always used if not overridden by LLPR settings. To get rid of all options for a printer, run the following command, replacing "printer" with the name of the queue: lpoptions -x printer Most printing systems will not run as the super-user but as a special user (usually "lp"). Therefore, make sure that the file you have chosen to print to is accessible to the user owning the spooler daemon.
Some pages come out all white (nothing is printed), and I am using CUPS.
I can't print to an SMB (Windows) printer.
My application seems to be frozen while LLPR is running.
How do I specify the IP address of my SMB server?
Some documents come out as white pages when printing.
I have CUPS and some options (such as N-up) seem to be always enabled even though I don't choose them in LLPR.
I configured a printer to print to a file, but I get "Permission denied" errors.

Troubleshooting
Problem On my PCL (or GDI) printer, I sometimes get error messages printing instead of my document.
Possible Cause and Solution Unfortunately, some Unix applications may generate non-compliant PostScript output that may not be supported by Ghostscript, or even the printer itself in PostScript mode. You can try to capture the output to a file and view the results with Ghostscript (gv or ghostview will allow you to do so interactively) and see if you get error messages. However, since the application is probably at fault, contact your software vendor to inform them of the issue. This is a known bug in Ghostscript (until GNU Ghostscript version 7.05) when the base color space of the document is indexed color space and it is converted through CIE color space. Because Postscript uses CIE color space for Color Matching System, you should upgrade Ghostscript on your system to at least GNU Ghostscript version 7.06 or later. You can find recent Ghostscript versions at www.ghostscript.com.
Some color images come out all black.
