How's it going.Let me read of your question. Give me a minute.
What's the serial number please?
Hello,I am the person that will be helping you today.
This occurs if the receiving end of the printer where the stapler is inserted does not make a full connection. Does it look and feel as though the stapler attachment is fully inserted and locked in place?
I will be standing by, looking forward to your response.
May I ask what your last statement means?
It is fully seated, you had it working, and there is no play.
Is it possible that the metal leads on the printer's end are corroded at all?
It sounds like the issue is on the printer's end. You may need to bring it into a repair shop nearby.
