Do you still have the old drum?

It wouldn't hurt just to put it back in to see if the noise diminishes, or stops.

 

Does it happen when printing anything, or certain types of print jobs, i.e., color vs. B/W ?

 

This printer is very electro-mechanical and localizing a noise will be extremely difficult to do on the basis of description alone. By trying a process of elimniation, you might be able to better localize the noise.

 

It sounds as if it is coming from the top back of the printer.  It was not making this sound before we changed the drum cartridge.

We replaced the new drum cartridge with the old.  It still makes the same noise.  I am not computer technician so not real sure what the names of parts are but could it be the part that is at the top of the printer behind the drum cartridge.  I have looked for a name for the part in the book but haven't found one.  It does have a serial number of CN-OK4907-71971-57F-B171. There are plenty of warning labels that it can reach 180 degrees and it would pull out from the top back. That is my best description I can give.

Any idea what general area of the printer where the clicking might be occurring?

That's the fuser. It's what melts and fuses the toner to the paper surface.

 

If you open the fuser cover, there are two blue latch handles, one at the left, one at the right. You can try to unlatch and re-latch these handles to ensure the fuser is correctly seated and secured.

Handles towards the front is unlatched... towards the back is latched.

Nope, no more ideas.

If the fuser needs replacement, the printer will give you an error message indicating so.

 We check it to make sure it was securly in place.  Still makes the clicking noise.  Do you know how often we should replace this part.  We have had this printer for 3 years and never replaced it.  Or do you have anymore suggestions as to what the problem might be?
