The status read-out says:

12 OPEN
OR NO EP-L

The manual describes this as:

"This message appears when either the printer is not closed
properly,
the EP-L cartridge is missing, or the cooling fan is not working."


But the printer is closed tight, securely and squarely, there is a
2
week old cartridge installed that I used last night, and the
ventilation fa is running fine.

Any ideas?

Thanks!
