This knowledge base article shows you how to properly clean CLS700 print head in your printer if you have print issues with your plate components. We recommend cleaning the print head regularly, while changing the ribbon or loading a new roll of reflective for example. To reduce any cross contamination, you could cover the area below the print unit with a clean cloth or sheet of paper while cleaning.
Dirt, grease and loose ink from ribbons can contaminate the print head and effect the print quality of your number plates. To clean it you’ll need to get to it, this means raising up the print unit and taking the off the ribbon and cores.
First, open up the printers top cover. The print unit (A) containing the ribbon and winding core holders also need to be raised up. Release the print unit by pushing the blue headed lever (B) and then lift it up. Next remove the winding core and the ribbon out of their drive slots to access the print head. Simply lift the ends with blue knobs up out their cradles and then pull the other ends off the notches. Place the ribbon aside if refitting it later.
The print head can be found on the bottom of the print unit. First, wipe off any foreign matter such as dust, dirt and adhesive substances of the print head with a lint free cloth or alcohol wipe, by softly wiping from one side to the other. Next, run the Citizen head cleaning pen along the black strip at the front of the head shown in the image above. This process should loosen and remove any contamination from the print head.
Once you’ve happy it’s clean, remove any protective cover you may have used. Replace or fit a new ribbon and winding core into the print unit, adjusting the blue knobs to eliminate wrinkles. Lower the print unit until it clicks and locks into place, then push the feed key on the control panel to tighten up the ribbon. Don’t forget to check the alignment controls before you start a fresh production run.
