Redistributing toner

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

White streaks or light printing occurs.
Toner low related message appears on the display.
The status LED blinks red.

If this happens, you can temporarily improve 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.


	Click this link to open an animation about redistributing toner.

Open the front door.


	Toner particles can be released inside the machine but it does not mean the machine is damaged. Contact a service representative when print quality problems occur.

Pull the corresponding toner cartridge out from the machine.

Thoroughly shake 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.

Printing problems

Condition

Possible cause

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. You may be able to temporarily extend the toner cartridge life. If this does not improve the print quality, install a new toner cartridge. The color tone might not be adjusted. Adjust the color tone. The paper may not meet paper specifications; for example, the paper may be too moist or rough (see the User's Guide). 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 toner cartridge needs cleaning. Contact a service representative. The surface of the LSU part inside the machine may be dirty. Clean the LSU, contact a service representative.
Toner specks	The paper may not meet specifications; for example, the paper may be too moist or rough (see the User's Guide). 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. Check the location of the machine. If the area is not well-ventilated, this problem may occur.
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 the User's Guide). 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 paper (see the User's Guide). 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. Cleaning the inside or contact a service representative. The paper path may need cleaning. Cleaning the inside or contact a service representative.
Vertical lines	If black vertical streaks appear on the page: The drum inside the printer has probably been scratched. Remove the imaging unit and install a new one. Contact a service representative. If white vertical streaks appear on the page: The surface of the LSU part inside the machine may be dirty. Cleaning the inside or contact a service representative. If vertical streaks appear on the page: The surface of the scanner glass and its white sheet may be dirty. Cleaning the inside or contact a service representative.
Color or Black background	If the amount of background shading becomes unacceptable: Change the image transfer belt if it has reached its lifespan. Contact a service representative. Check the environmental conditions: very dry conditions (low humidity) or a high level of humidity (higher than 80% RH) can increase the amount of background shading. Remove the old toner cartridge and install a new one.
Toner smear	If toner smears on the page: Clean the inside of the machine. Cleaning the inside or contact a service representative. Check the paper type and quality (see the User's Guide). Remove the imaging unit and install a new one. Contact a service representative. Change the image transfer belt if it has reached its lifespan. Contact a service representative.
Vertical repetitive defects	If marks repeatedly appear on the printed side of the page at even intervals: The imaging unit may be damaged. If a repetitive mark occurs on the page, run a cleaning sheet through several times to clean the imaging unit. Cleaning the inside. If you still have the same problems, remove the imaging unit and install a new one. Contact a service representative. 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 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 in Printing Preferences (see the User's Guide).
Misformed characters	If characters are improperly formed and producing hollow images, the paper stock may be too slick. Try different paper (see the User's Guide). If characters are improperly formed and producing a wavy effect, the scanner unit may need service. Cleaning the scan unit or contact a service representative.
Page skew	Ensure that the paper is loaded properly. Check the paper type and quality (see the User's Guide). Ensure that the paper or other material is loaded correctly and the guides are not too tight or too loose against the paper stack. Ensure that the standard tray right bottom door, dual cassette feeder right bottom door or high capacity feeder right bottom door is securely closed. If the bottom doors are not completely closed, open and close the bottom doors.
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 the User's Guide). 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 the User's Guide). Turn the stack of paper over in the tray. Also try rotating the paper 180° in the tray. Ensure that the standard tray right bottom door, dual cassette feeder right bottom door or high capacity feeder right bottom door is securely closed. If the bottom doors are not completely closed, open and close the bottom doors.
Back of printouts are dirty	Check for leaking toner. Clean the inside of the machine. Cleaning the inside or contact a service representative.
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 and need replacing. Remove the imaging unit and install a new one. Contact a service representative. The machine may require repair. Contact a service representative.

Remove the imaging unit and install a new one. Contact a service representative. 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: If you are using transparencies, try another type of transparency. Because of the composition of transparencies, some character voids are normal. 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 the User's Guide).
Horizontal stripes	If horizontally aligned black 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. Contact a service representative. 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 paper (see the User's Guide).
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.

Copying problems

Condition	Suggested solution
Copies are too light or too dark	Use Light and Dark arrows to lighten or darken the backgrounds of copies in the Basic tab of the Copy menu.
Smears, lines, marks, or spots appear on copies.	If the defects are on the original, press left/right arrow to lighten the background of your copies in the Basic tab of the Copy menu (see the User's Guide). If there are no defects on the original, clean the scan unit. Cleaning the scan unit or contact a service representative.
Copy image is skewed.	Ensure that the original is face down on the scanner glass or face up in the DADF. Check that the copy paper is loaded correctly. If the problem persists, the machine may require repair. Contact a service representative.
Blank copies print out.	Ensure that the original is face down on the scanner glass or face up in the DADF.
Image rubs off the copy easily.	Replace the paper in the tray with paper from a new package. In high humidity areas, do not leave paper in the machine for extended periods of time.
Frequent copy paper jams occur.	Fan the stack of paper, then turn it over in the tray. Replace the paper in the tray with a fresh supply. Check/adjust the paper guides, if necessary. Ensure that the paper is the proper paper weight. Check for copy paper or pieces of copy paper remaining in the machine after a paper jam has been cleared.
Toner cartridge produces fewer copies than expected before running out of toner.	Your originals may contain pictures, solids, or heavy lines. For example, your originals may be forms, newsletters, books, or other documents that use more toner. The DADF may be left open while copies are being made. The machine may be turned on and off frequently.

Scanning problems

Conditon	Suggested solutions
The scanner does not work.	Make sure that you place the original to be scanned face down on the scanner glass, or face up in the DADF. There may not be enough available memory to hold the document you want to scan. Try the Prescan function to see if that works. Try lowering the scan resolution rate. Check that the machine cable is connected properly. Make sure that the machine cable is not defective. Switch the cable with a known good cable. If necessary, replace the cable. Check that the scanner is configured correctly. Check scan setting in the Easy Document Creator or the application you want to use to make certain that the scanner job is being sent to the correct port (for example, USB001).
The unit scans very slowly.	Check if the machine is printing received data. If so, scan the document after the received data has been printed. Graphics are scanned more slowly than text. Communication speed slows in scan mode because of the large amount of memory required to analyze and reproduce the scanned image. Set your computer to the ECP printer mode through BIOS setting. It will help to increase the speed. For details about how to set BIOS, refer to your computer user’s guide.
Message appears on your computer screen: Device can’t be set to the H/W mode you want. Port is being used by another program. Port is Disabled. Scanner is busy receiving or printing data. When the current job is completed, try again. Invalid handle. Scanning has failed.	There may be a copying or printing job in progress. Try your job again when that job is finished. The selected port is currently being used. Restart your computer and try again. The machine cable may be improperly connected or the power may be off. The scanner driver is not installed or the operating environment is not set up properly. Ensure that the machine is properly connected and the power is on, then restart your computer. The USB cable may be improperly connected or the power may be off.

Fax problems (optional)

condition	suggested solutions
The machine is not working, there is no display, or the buttons are not working.	Unplug the power cord and plug it in again. Ensure that there is power being supplied to the electrical outlet.
No dial tone sounds.	Check that the phone line is properly connected. Check that the phone socket on the wall is working by plugging in another phone.
The numbers stored in memory do not dial correctly.	Make sure that the numbers are stored in memory correctly (see the User's Guide).
The original does not feed into the machine.	Make sure that the paper is not wrinkled and you are inserting it in correctly. Check that the original is the right size, not too thick or thin. Make sure that the DADF is firmly closed. The DADF rubber pad may need to be replaced. Contact a service representative.
Faxes are not received automatically.	The receiving mode should be set to fax. Make sure that there is paper in the tray. Check to see if the display shows any error message. If it does, clear the problem
The machine does not send.	Make sure that the original is loaded in the DADF or on the scanner glass. Check the recipient’s fax machine (if it has a problem).
The incoming fax has blank spaces or is of poor-quality.	The fax machine sending you the fax may be faulty. A noisy phone line can cause line errors. Check your machine by making a copy. The toner cartridge may be empty. Replace the toner cartridge.
Some of the words on an incoming fax are stretched.	The fax machine sending the fax had a temporary document jam.
There are lines on the originals you sent.	Check your scan unit for marks and clean it. Cleaning the scan unit.
The machine dials a number, but the connection with the other fax machine fails.	The other fax machine may be turned off, out of paper, or cannot answer incoming calls. Speak with the other machine operator and ask her/him to solve out the problem.
Faxes do not store in memory.	There may not be enough memory space to store the fax. If the display indicating the memory status shows, delete any faxes you no longer need from the memory, and then try to store the fax again.
Blank areas appear at the bottom of each page or on other pages, with a small strip of text at the top	You may have chosen the wrong paper settings in the user option setting. For details about paper settings (see the User's Guide).

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. Print a configuration page and verify that the PS version is available for printing. If the problem persists, contact a service representative.
“Limit Check Error” message appears.	The print job was too complex.	You might need to reduce the complexity of the page or install more memory.
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 dual cassette feeder (tray 3, tray 4) is not selected in the driver.	The printer driver has not been configured to recognize the optional dual cassette feeder (tray 3, tray 4).	Open the PostScript driver properties, select the Device Options tab, and set the tray option of the Tray Options section.
When printing a document in MAC 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.


	Refer to Microsoft Windows 2000/XP/2003/Vista User’s Guide that came with your computer for further information on Windows error messages.

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).
The machine does not print whole pages, and output is printed on half the page.	It is a known problem that occurs when a color machine is used on version 8.51 or earlier of Ghostscript, 64-bit Linux OS, and has been 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/ghostscript/ and install it to solve this problem.
I cannot scan via Gimp Front-end.	Check if Gimp Front-end has Xsane: Device dialog on the Acquire menu. If not, you should install Xsane plug-in for Gimp on the your computer. You can find Xsane plug-in package for Gimp on Linux distribution CD or Gimp home page. For the detailed information, refer to the Help for Linux distribution CD or Gimp Front-end application. If you wish to use another kind of scan application, refer to application’s Help.
I encounter the “Cannot open port device file” error 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 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.
The machine does not appear on the scanners list.	Ensure your machine is attached to your computer, connected properly via the USB port, and is turned on. Ensure the scanner driver for your machine is installed in your system. Open Unified Linux Driver configurator, switch to Scanners configuration, then press Drivers. Make sure that driver with a name corresponding to your machine's name is listed in the window. 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. This usually happens when starting a scan procedure. An appropriate message box appears. To identify the source of the problem, open the Ports configuration and select the port assigned to your scanner, port's symbol /dev/mfp0 corresponds to LP:0 designation displayed in the scanners’ options, /dev/mfp1 relates to LP:1, and so on. USB ports start at /dev/mfp4, so scanner on USB:0 relates to /dev/mfp4 respectively and so forth sequentially. In the Selected port pane, you can see if the port is occupied by another 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 port application is not functioning properly.
The machine does not scan.	Ensure a document is loaded into the machine, ensure your machine is connected to the computer. If there is an I/O error while scanning.
