Faint Black Print

[DHeys]

My Versalink C405 Printer has suddenly started to print black text in a very pale grey.  Colours are printing fine.  Test pages are exactly the same, ie bright, crisp colours but bery faint black text.  I have replaced toner, but no improvement at all.  Would appreciate any help.

Hi,

Possible to be from the Black Imaging Unit. 

But first try to clean the CTD sensor circled below (behind the back cover).

We have the exact same problem. We could not locate that part on our printer. We removed two pieces with green handles at the back of the unit but nothing that looked like the picture.

Hi,

Sorry! It was my fault! That image is from a WC6515.

This is the photo with the CTD sensor on VersaLink C400/405. And to have access on it you must remove the Transfer Belt assy by removing the waste bottle, opening the printer top cover and removing the belt.

Hi, I'm having the same problem with very feint black print, but no problem at all with colours.

I've opened up the C405 and cleaned the CTD sensor as per the picture above but still getting this same problem.

What is the black imaging unit and is that something I can clean/inspect/replace myself?

Thanks in advance

I had to buy this and it fixed my issue. Unfortunately, I couldn't find just the black unit. They are new fusers.

its an expensive option but replacing the black imaging drum worked for our C400n, only for about 2 weeks , the faint black text problem has returned , any more ideas welcome
