Re: looking for a white ribbon cable

This is no sparepart and belongs to the printhead which is only sold in one part (Flat white cable, printhead and printhead cover).

Why won't my printer print black and white and I have cleaned it, changed settings, and changed cartridge?

The printer ribbon contact may be at fault. With the price of printers so low it makes no sense to repair it, just replace it. The last printer i needed was free after rebate, just the sales tax of $5 is all it cost me at a big box electronics store.

We have been getting white horizontal lines on our documents. Both print heads were recently replaced and that did not solve the problem. What part is needing replaced?

I had this same problem and none of the printer services (clean printhead, align printer, calibrate linefeed) fixed the problem. After trying every solution that I found on the internet with no success I was able to fix the problem by cleaning two critical parts of the printer.
1. Turn off the printer and open it as though you are going to change the printheads.
2. Towards the back of the printer you will see a thin clear plastic ribbon that has very small black lines on it. Very, very, very gently clean this ribbon. I used a lint free cloth and some glass cleaner. Spray the cleaner on the cloth and slide the cloth against both sides of the ribbon. Do not pull on the ribbon. This ribbon is used to tell the printhead how far it has moved from side to side.
3. Next locate the silver bar that runs across the back of the printer. This bar is used to feed the paper through the printer as it is printing a document. On the left side of the bar you will see some plastic guides that hold the bar in place. On the outside of the plastic guides you should see a clear plastic disc made of the same material as the ribbon above. This disc also has very small black lines on it. Again very, very, very gently clean this plastic disc. This disk is used to tell the printheads how far it has travelled down the page. This is the one that was causing the problem. The dust or dried ink or whatever was on the disc was causing the printer to incorrectly calibrate the linefeed and was causing the white lines to appear on my documents.
4. Use the "calibrate linefeed" function of the printer services to recalibrate the linefeed and the white lines will hopefully be gone.

Alarm flashing goes to prop

This is a "spacing alarm". check that the printhead moves freely from left to right. If not, remove the ribbon and try it again. If it is moving freely then it should be ok, if not it will need most likely the space motor or the main board replaced. In some cases it is also possibly the white carriage cable that runs from your main board to the space motor. Hope this helps.

How can i relace the dmp printer head with new one

  • 1-Turn off printer,

  • 2-Open the printer's front cover to access the printer's ribbon and printhead.
  • 3-Spray the ribbon and printhead with short sprays of air from a can of compressed air to remove any ink, dust and dirt buildup from the components.
  • 4-Use a flashlight to locate the printhead's adjustment lever. The lever is on the left side of the printhead.
  • 5-Push the lever toward the ribbon. This will place the printhead closer to the ribbon so the print will be darker.
  • 6-Close the printer's front cover. Turn on the printer.
  • 7-Print a test document. If the print is still too light, replace the ribbon.

    If the print is too dark, turn off the printer and move the printhead's adjustment lever slightly away from the ribbon.

    Change print head on kodak 5300 printer

    Are your asking how to replace the printhead?

    First you need to turn On the printer and open the printer access door where you can see the Ink. Now wait for the Printhead to stop into the middle then remove the ink cartridges both ink and black., Now to rmove the Old printhead you need to press a Tab which is hidden on the printhead., heres the step to remove the printhead which for me the hardest part

    -Point your index finger on the white sticker that attached on the printhead or the bullseye sticker(If theres no white sticker on the print head just put your index finger on the middle of the printhead)

    -Now your index finger is on the middle of the white sticker right? Move your index finger upward unti you feel a latch that you can press., Just press and full then your printhead wil be removed

    -Now Your ready to insert your new printhead
    -To insert new printhead just put the printhead on the carriage of the printer and gently press the white sticker of your new printhead make sure that you will hear a clicking sounds then put your cartridges back

    -Theres some instances that the printhead will not stay on the middle., it keeps on staying on the right or on the leftside for you to solve that heres the step

    -Turn on the printer open printer access door and wait for the printhead move into the center and if the printhead its on the center immediately unplug the power cable so the printhead will not move.

    Okidata 320/420 printhead not printing aligned.

    Clean the large silver rod that runs through the carriage. It is dirty and not allowing the carriage to move as freely as it should. Ideally it should be left dry. Also change the ribbon. The same motor drives the carriage and the ribbon. If it has a bind, the same thing can happen. Hope it helps Ed
