CLS700 Not Printing

CLS700 Not Printing

This knowledge base article shows you what steps to take when your CLS700 is not printing correctly onto your components, with power, print head cleaning and component solutions.

No Power Or LED Lights

Connect CLS621 to PC
If the lights remain off on the printers control panel, check the power is turned on and all the cables are connected properly. Check the cords for signs of damage, and if so replace them before trying to use the printer again. Next check the USB cable connection to your computer, the printer can’t print something it’s not receiving. Finally, check the fuses and power to the socket or your building.

Not Printing

When reflective panels are actually feeding through the machine but nothing is being printed, there are a few things to check. Start by checking there’s nothing stuck and preventing the printing unit from operating correctly.

Dirty Print Head

Clean CLS700 Print head using the pen
Check the print head on the bottom of the print unit for dust and contamination. If it’s dirty or blocked, follow this print head cleaning guide to clean it correctly. If you’re having to clean it frequently, consider re-locating your plate production to a clean, dust free location and only use approved ribbons.

Stuck Media

CLS700 Options
Over time bits can become stuck to the print head, this happens more often when the temperature settings are set too high. To fix this you need to clean the print head and then reset the printers settings.

Start by removing the printers top cover, then push the blue lever to release the print unit. Lift it up and check the print head on the bottom for any contamination. Carefully pull away any visible pieces before wiping it with a cloth or cleaning pen. Finally check the print head temperature by altering your settings to those shown in the image above.

Dirty or Damaged Platen

CLS700 Not Printing Correctly
The Platen at the front of the printing unit (A) is used to pull plate components through the machine. Dirt and contamination can prevent it from operating correctly. Clean a dirty one with ethyl alcohol, and going forward ensure you’re only using approved ribbons. If the Platen is deformed or has been damaged in some way, it will need replacing with a new one – contact technical support for assistance.

Wrong Media Alignment
