Troubleshooting

This chapter gives helpful information for what to do if you encounter an error.

Redistributing toner

When a toner is low, faded or light areas may appear. It is possible that colored images may be printed with incorrect colors due to flawed mixing of toner colors when the toner level of the colored toner cartridge is low. You can temporarily improve print quality by redistributing the toner.

  • The toner-related message saying that the toner is low may appear on the display.

  • The Smart Panel program window appears on the computer telling you which color cartridge is low on toner.

  1. Using the handle, completely open the front cover.

  2. Grasp the handles on the toner cartridge and pull the cartridge out.

    [Caution]
    • Do not touch the green surface, the OPC drum or the front of the toner cartridge, with your hands or any other material. If the green surface is contaminated, it might affect the printout quality. Use the handle on each cartridge in order to avoid touching this area.

    • Be careful not to scratch the surface of the paper transfer belt.

    • If you leave the front cover open for more than a few minutes, the OPC drum can be exposed to light. This will cause damage to the OPC drum. Close the front cover when the installation needs to be halted for any reason.

    • If you open the front cover, be careful not to touch the underneath the control panel (the lower part of the fuser unit). The temperature of the fuser unit might be high and could damage your skin.

    [Note]

    When you open the front cover and work inside the machine, it is highly recommend that you remove the paper transfer belt first. Because the work you do could contaminate the paper transfer belt.

  3. Holding both handles on the toner cartridge, thoroughly rock it from side to side to redistribute the toner.

    [Note]

    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.

  4. Slide the toner cartridge back into the machine.

  5. Close the front cover. Ensure that the cover is securely closed.

    [Caution]

    If the front 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 below guidelines.

  • Ensure that the adjustable guides are positioned correctly (See Loading paper in the 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 paper type and size).

  • Ensure that the recommended side of the print media is facing up in the tray, or facing down in the multi-purpose tray.

  • If paper jams occur frequently when you print on A5/B5-sized paper: Load the paper into the tray with the long edge facing the front of the tray.

    If load the paper this way, printing both sides of the paper (duplex) is not supported.

    In the Printing Preferences window, set the page orientation to be rotated 180 degrees (See Opening printing preferences).

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 (See Redistributing toner). If this does not improve the print quality, install a new toner cartridge.

  • 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 toner cartridge 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 Paper (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 toner cartridge inside the machine has probably been scratched. Remove the toner cartridge and install a new one (See Replacing the toner cartridge).

If white vertical streaks appear on the page:

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 (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 (See Replacing the toner cartridge).

Toner smear

If toner smears on the page:

Vertical repetitive defects

If marks repeatedly appear on the printed side of the page at even intervals:

  • The toner cartridge may be damaged. If you still have the same problem, remove the toner cartridge and, install a new one (See Replacing the toner cartridge).

  • 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 Opening printing preferences).

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.

  • The toner cartridge may be defective. Remove the toner cartridge and install a new one (See Replacing the toner cartridge).

  • The machine may require repair. Contact a service representative.

Loose toner

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 Print media specifications).

Horizontal stripes

If horizontally aligned black streaks or smears appear:

  • The toner cartridge may be installed improperly. Remove the cartridge and reinsert it.

  • The toner cartridge may be defective. Remove the toner cartridge and install a new one (See Replacing the toner cartridge).

  • 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 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).

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

When printing a document in Mac OS with Acrobat Reader 6.0 or higher, colors print incorrectly.

Make sure that the resolution setting in your machine driver matches the one in Acrobat Reader.

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.

  • 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.

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 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 colors.

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 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 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.

When printing a document over the network in SuSE 9.2, the printer does not print.

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 later version of CUPS (Common UNIX Printing System) (cups-1.1.22 or higher).
