Solution

There are two tests which can be performed on the printer:

  • The hardware self test

  • The software test

How to perform a hardware self test with the printer:
This test is used to determine whether or not you have a hardware fault with your printer.

  1. Put one sheet of paper into the paper feeder.

  2. Hold both buttons down while the printer is off. The lights will come on and begin to flash.

  3. Release both buttons when the lights start to flash. The printer should now print a self test.

  4. Check the results against those listed in the table and take any suggested action to resolve the problem.

    Result of test

    Possible reason

    Suggested action

    Prints out a series of black and color lines

    Mechanically the printer is fine

    Proceed to the software test

    Only prints out a series of black or a series of color lines*

    Either one of the cartridges or one side of the cartridge carrier isn't functioning properly.

    Swap the cartridges around (put the black on the color side and vice versa) and repeat the test. If it prints a different set of lines (i.e. if it was printing black but is now printing color), the cartridge carrier is at fault. Try cleaning the contacts on the cartridge carrier. If the problem persists, the printer may have developed a fault. However, if it prints the same set of lines, the cartridge may need cleaning (see below) or it may be empty.

    Page feeds through but doesn't print anything

    Didn't do the test properly

    Repeat the test, ensuring that you press the buttons in the correct order.
     
    Cartridges are empty or cartridge nozzles are blocked

    Check if any ink is coming out of the cartridges by removing them from the printer and dabbing the nozzles (at the bottom of the cartridge) onto a clean piece of tissue. If no ink comes out, the cartridge may be empty or the nozzles may be blocked. Try cleaning the nozzles or try a different cartridge.
     
    Contacts on the cartridges or the cartridge carrier are dirty/faulty

    Clean the copper contacts on the back of the cartridges and also on the cartridge carrier (where the cartridges snap in). Use a clean, dry, lint-free cloth to remove any dust or excess ink.
     
    Power supply problem

    The printer may have enough power to feed the page through but not enough to print. If you are using a surge protector, multi-socket or extension lead, try plugging the printer directly into a wall socket.

    Nothing happens but the lights are flashing

    Paper path is blocked

    Check the paper feed path for any obstructions and remove them. Remove the cartridges and try to feed a page through. If it feeds through, perhaps the cartridges weren't snapped into place securely.
     
    Faulty or empty cartridges

    Remove cartridges and repeat test. If the page feeds through, clean the cartridges/carrier (see above). Repeat test, with both cartridges installed. If unsuccessful, try the test with one cartridge at a time to identify which cartridge is faulty/empty.

    Nothing happens

    Power supply problem

    Check all the power cable and adapter connections. If you are using a surge protector, multi-socket or extension lead, try plugging the printer directly into a wall socket. Check the fuse in the plug. If there is still nothing happening, the printer or the power adapter may have developed a fault.

     * Note: This test is based on using a black/color cartridge set. The color cartridge should have three colors - yellow, magenta and cyan. If you are using a photo/color set, you could still have black and color lines as the photo cartridge has black, light magenta and light cyan.

How to perform the software test with the printer:
This test is used to try to determine if you have a communication problem with the printer. It is performed in native DOS and eliminates any possible interference from other software. Before attempting this test, you should ensure that the printer is connected directly to the PC via the parallel port. If you have the printer connected via a scanner or another device, you should remove the scanner so that there is nothing between printer and PC that could interfere with communication.
Microsoft Windows 3.1/3.11:

  1. Restart the computer.

  2. Press F8 when Starting MS-DOS appears.

  3. Answer NO to all questions until you are at the DOS prompt.

  4. Type CD WINDOWS and press ENTER.

  5. Type CD SYSTEM and press ENTER.

  6. *If you are using a black/color cartridge set, type COPY/B LXMDTSTC.OUT LPT1: and press ENTER. (If using the photo/color cartridge set, type COPY/B LXMDTSTK.OUT LPT1: and press ENTER.)

Microsoft Windows 95/98:

  1. Restart the computer.

  2. Press F8 when Starting Windows 95 appears. (With Microsoft Windows 98 nothing appears.)

  3. Choose Safe Mode Command Prompt Only.

  4. Type CD WINDOWS and press ENTER.

  5. Type CD SYSTEM and press ENTER.

  6. *If you are using a black/color cartridge set, type COPY/B LXMDTSTC.OUT LPT1:  and press ENTER. (If using the photo/color cartridge set, type COPY/B LXMDTSTK.OUT LPT1: and press ENTER.)

If the test is successful, a Lexmark test page is printed. This indicates that the problem lies within Microsoft Windows and the printer software/setup.
If it doesn't print, you may receive one of the messages below. Try the suggested action to resolve the problem:

Message on screen

Reason for message

Suggested action

'0 file(s) copied'

Indicates that the PC couldn't locate the test file. This could be because the printer driver isn't installed properly or the path specified is incorrect.

Ensure that the printer driver is installed in Microsoft Windows and repeat test.

'Too many' or 'Too few parameters'

Step six was not typed correctly.

Repeat step six.

'1 file(s) copied'

PC wrongly believes that the file has been received and printed. The file is effectively lost somewhere between port cable and printer.


    Disconnect the parallel cable, leave it disconnected from the LTP port and try the test again.
    If you get the same message, the port may need to be examined by a professional. If you receive a different message, the port should be OK.
    Remove the cartridges and repeat the test. There is a possibility that the contacts on the cartridges could be causing a communication fault.
    If that doesn't work, try the test again using another specified cable (see below).
    If problem persists, it's likely to be due to a problem with the port on the printer itself.

'Write/fault error' or 'Not ready writing device LPT1'*

There is a problem with the parallel cable, or the printer is either not connected properly or not powered on.

Disconnect and reseat the parallel cable and the power cable, and try the test again.
If unsuccessful ,try the test again using a different parallel cable that matches the required specifications (IEEE 1284 compliant).

* The number 1 in 'LTP1' corresponds to the number of your LTP port. While this is typically 'LTP1' ,  it could also be 'LTP2' , 'LTP3' and so on. Substitute the correct number as appropriate.
