Troubleshooting

This chapter gives helpful information for what to do if you encounter an error. If your machine has a display screen, check the message on the display screen first to solve the error. If you cannot find a solution in this User's Guide or the problem consists, call for service.

This chapter includes:

Redistributing toner

When the toner cartridge is near the end of its life:

White streaks or light printing occurs.
The toner-related message saying that the toner is low may appear on the display.
The Status LED blinks red.

If this happens, you can temporarily improve the print quality by redistributing the remaining toner in the cartridge. In some cases, white streaks or light printing will still occur even after you have redistributed the toner.

Open the top cover and pull the toner cartridge out.

Thoroughly roll the cartridge five or six times to distribute the toner evenly inside the cartridge.


	If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.

Reinsert the toner cartridge.

Close the top cover. Ensure that the cover is securely closed.


	If the top cover is not completely closed, the machine will not operate.

Tips for avoiding paper jams

By selecting the correct media types, most paper jams can be avoided. When a paper jam occurs, refer to the next guidelines.

Ensure that the adjustable guides are positioned correctly (See Loading paper in tray).

Do not overload the tray. Ensure that the paper level is below the paper capacity mark on the inside of the tray.
Do not remove paper from the tray while your machine is printing.
Flex, fan and straighten paper before loading.
Do not use creased, damp, or highly curled paper.
Do not mix paper types in a tray.
Use only recommended print media (See Setting the default tray and paper).
Ensure that the recommended side of the print media is facing down in the tray, or facing up in the multi-purpose tray.

Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, there might be a reduction in print quality. See the table below to clear the problem.

Condition	Suggested Solutions
Light or faded print	If a vertical white streak or faded area appears on the page, the toner supply is low or the imaging unit is worn. You may be able to temporarily extend the toner cartridge life (SeeRedistributing toner). If this does not improve the print quality, install a new toner cartridge or imaging unit. The paper may not meet paper specifications; for example, the paper may be too moist or rough (See Print media specifications). If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print resolution and turn the toner save mode off. See the help screen of the printer driver. A combination of faded or smeared defects may indicate that the imaging unit needs cleaning (See Cleaning the inside). The surface of the LSU part inside the machine may be dirty (See Cleaning the inside).
Toner specks	The paper may not meet specifications; for example, the paper may be too moist or rough (See Print media specifications). The transfer roller may be dirty. Clean the inside of your machine. Contact a service representative. The paper path may need cleaning. Contact a service representative.
Dropouts	If faded areas, generally rounded, occur randomly on the page: A single sheet of paper may be defective. Try reprinting the job. The moisture content of the paper is uneven or the paper has moist spots on its surface. Try a different brand of paper (See Print media specifications). The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or brand of paper. Change the printer option and try again. Go to Printing Preferences, click Paper tab, and set type to Thick (See Opening printing preferences). If these steps do not correct the problem, contact a service representative.
White Spots	If white spots appear on the page: The paper is too rough and a lot of dirt from a paper falls to the inner devices within the machine, so the transfer roller may be dirty. Clean the inside of your machine (See Cleaning the inside). The paper path may need cleaning (See Cleaning the inside).
Vertical lines	If black vertical streaks appear on the page: The surface (drum part) of the imaging unit inside the machine has probably been scratched. Remove the imaging unit and install a new one (See Replacing the imaging unit). If white vertical streaks appear on the page: The surface of the LSU part inside the machine may be dirty (See Cleaning the inside).
Color or Black background	If the amount of background shading becomes unacceptable: Change to a lighter weight paper (See Print media specifications). Check the environmental conditions: very dry conditions or a high level of humidity (higher than 80% RH) can increase the amount of background shading. Remove the old imaging unit and, install a new one (See Replacing the imaging unit). If this problem persists, contact a service representative.
Toner smear	If toner smears on the page: Clean the inside of the machine (See Cleaning the inside). Check the paper type and quality (See Print media specifications). Remove the imaging unit and then, install a new one (See Replacing the imaging unit).
Vertical repetitive defects	If marks repeatedly appear on the printed side of the page at even intervals: The imaging unit may be damaged. If you still have the same problem, remove the imaging unit and, install a new one (See Replacing the imaging unit). Parts of the machine 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.
Background scatter	Background scatter results from bits of toner randomly distributed on the printed page. The paper may be too damp. Try printing with a fresh ream of paper. Do not open reams 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 in Printing Preferences (See Opening printing preferences).
Toner particles are around bold characters or pictures	The toner might not adhere properly to this type of paper. Change the printer option and try again. Go to the Printing Preferences, click the Paper tab, and set the paper type to Recycled.
Misformed characters	If characters are improperly formed and producing hollow images, the paper stock may be too slick. Try different paper (See Print media specifications).
Page skew	Ensure that the paper is loaded properly. Check the paper type and quality (See Print media specifications). Ensure that the guides are not too tight or too loose against the paper stack.
Curl or wave	Ensure that the paper is loaded properly. Check the paper type and quality. Both high temperature and humidity can cause paper curl (See Print media specifications). Turn the stack of paper over in the tray. Also try rotating the paper 180° in the tray.
Wrinkles or creases	Ensure that the paper is loaded properly. Check the paper type and quality (See Print media specifications). Turn the stack of paper over in the tray. Also try rotating the paper 180° in the tray.
Back of printouts are dirty	Check for leaking toner. Clean the inside of the machine (See Cleaning the inside).
Solid Color or Black pages	The imaging unit may not be installed properly. Remove the imaging unit and reinsert it. The imaging unit may be defective. Remove the imaging unit and install a new one (See Replacing the imaging unit). The machine may require repair. Contact a service representative.
Loose toner	Clean the inside of the machine (See Cleaning the inside). Check the paper type and quality (See Print media specifications). Remove the imaging unit and then, install a new one (See Replacing the imaging unit). If the problem persists, the machine may require repair. Contact a service representative.
Character Voids	Character voids are white areas within parts of characters that should be solid black: You may be printing on the wrong surface of the paper. Remove the paper and turn it around. The paper may not meet paper specifications (See Print media specifications).
Horizontal stripes	If horizontally aligned black streaks, white streaks or smears appear: The imaging unit may be installed improperly. Remove the imaging unit and reinsert it. The imaging unit may be defective. Remove the imaging unit and install a new one (See Replacing the imaging unit). The machine might had a minor shock during printing or copying. There is no problem with the machine. Try printing again. If the problem persists, the machine may require repair. Contact a service representative.
Curl	If the printed paper is curled or paper does not feed into the machine: Turn the stack of paper over in the tray. Also try rotating the paper 180° in the tray. Change the printer option and try again. Go to Printing Preferences, click Paper tab, and set type to Thin (See Opening printing preferences).
An unknown image repetitively appears on a few sheets or loose toner, light print, or contamination occurs.	Your machine is probably being used at an altitude of 1,000 m (3,281 ft.) or above.The high altitude may affect the print quality, such as loose toner or light imaging. Change the correct altitude setting to your machine (See Altitude adjustment).

Common PostScript problems

The following situations are PS language specific and may occur when several printer languages are used.

Problem	Possible cause	Solution
PostScript file cannot be printed.	The PostScript driver may not be installed correctly.	Install the PostScript driver (See Installing locally connected machine’s driver). Print a configuration page and verify that the PS version is available for printing. Reinstall the PS driver. If the problem persists, contact a service representative.
“Limit Check Error” report prints.	The print job was too complex.	You might need to reduce the complexity of the page or install more memory (See Installing a memory module).
A PostScript error page prints.	The print job may not be PostScript.	Make sure that the print job is a PostScript job. Check to see whether the software application expected a setup or PostScript header file to be sent to the machine.
The optional tray is not selected in the driver.	The printer driver has not been configured to recognize the optional tray.	Open the PostScript driver properties, select the Device Options tab, and set the tray option.
When printing a document in Macintosh with Acrobat Reader 6.0 or higher, colors print incorrectly.	The resolution setting in the printer driver may not be matched with the one in Acrobat Reader.	Make sure that the resolution setting in your printer driver matches the one in Acrobat Reader.

Common Windows problems

Condition	Suggested solutions
“File in Use” message appears during installation.	Exit all software applications. Remove all software from the printer’s startup group, then restart Windows. Reinstall the printer driver.
“General Protection Fault”, “Exception OE”, “Spool 32”, or “Illegal Operation” messages appear.	Close all other applications, reboot Windows and try printing again.
“Fail To Print”, “A printer timeout error occurred” messages appear.	These messages may appear during printing. Just keep waiting until the machine 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.

Common Linux problems

condition	Suggested solutions
The machine does not print.	Check if the printer driver is installed in your system. Open Unified Driver Configurator and switch to the Printers tab in Printers configuration window to look at the list of available machines. Make sure that your machine is displayed on the list. If not, open Add new printer wizard to set up your device. Check if the machine is started. Open Printers configuration and select your machine on the printers list. Look at the description in the Selected printer pane. If its status contains Stopped string, press the Start button. After that normal operation of the machine should be restored. The “stopped” status might be activated when some problems in printing occurred. For instance, this could be an attempt to print a document when the port is claimed by a scanning application. Ensure the port is not busy. Since functional components of machine (printer and scanner) share the same I/O interface (port), the situation of simultaneous access of different user applications to the same port is possible. To avoid possible conflicts, only one of them at a time is allowed to gain control over the device. The other user will encounter “device busy” response. You should open ports configuration and select the port assigned to your machine. In the Selected port pane you can see if the port is occupied by some other application. If this is the case, you should either wait for completion of the current job or press the Release port button, if you are sure that the present application is not functioning properly. Check if your application has special print option such as “-oraw”. If “-oraw” is specified in the command line parameter, then remove it to print properly. For Gimp front-end, select “print” -> “Setup printer” and edit command line parameter in the command item. The CUPS (Common UNIX Printing System) version distributed with SuSE Linux 9.2 (cups-1.1.21) has a problem with ipp (Internet Printing Protocol) printing.Use the socket printing instead of ipp or install a later version of CUPS (cups-1.1.22 or higher).
Some color images come out all black.	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 in unexpected color.	This is a known bug in Ghostscript (until GNU Ghostscript version 7.xx) when the base color space of the document is indexed RGB 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 8.xx or later. You can find recent Ghostscript versions at www.ghostscript.com.
The machine does not print whole pages and its output is half page printed.	It is a known problem that occurs when a color printer is used on version 8.51 or earlier of Ghostscript, 64-bit Linux OS, and reported to bugs.ghostscript.com as Ghostscript Bug 688252.The problem is solved in AFPL Ghostscript v. 8.52 or above. Download the latest version of AFPL Ghostscript from http://sourceforge.net/projects/gho
I encounter error “Cannot open port device file” when printing a document.	Avoid changing print job parameters (via LPR GUI, for example) while a print job is in progress. Known versions of CUPS (Common UNIX Printing System) server break the print job whenever print options are changed and then try to restart the job from the beginning. Since Unified Linux Driver locks the port while printing, the abrupt termination of the driver keeps the port locked and unavailable for subsequent print jobs. If this situation occurs, try to release the port by selecting Release port in Port configuration window.

	It will take longer to print when you print a PDF file as an image.

The document has printed, but the print job has not disappeared from the spooler in Mac OS X 10.3.2.

Update your Mac OS to OS Mac OS X 10.3.3. or higher.

Some letters are not displayed normally during the cover page printing.

Mac OS cannot create the font during the cover page printing. The English alphabet and numbers are displayed normally on the cover page.
