#1 Hi, it looks like is the LC LM PH miss firing, you can try to remove the ph and clean the PH contact point on the Ph and carriage, then reinsert the ph and test print. if problem persist, you may need to replace the PH.

Hello @bjorn.b5176

It could be an electrical problem due to missing contacts or parts damaged.

What @kelvin.ng5186 suggests it’s a good point, if not, replace the affected printhead LM/LC.

If it’s not solving it, then a tech must see directly the issue.

#3 we have replaced the LC/LM print head. While it was out we cleaned the contacts. We still have the issue intermittently
