If you bought imaging unit over the internet, it might not be compatible for your country/printer.
Look at the serial number of the printer, the characters after the '/' is your country code, and the imaging must match.

It is the first imaging unit .It worked fine for some years. Perhaps this happened after customer replaced toner .I have checed it myself and repositioned it with no result.
