My Histology Lab is currently using a Leica tissue processor and have 
encountered some severe processing problems.  The stained slides have nuclear 
"ghosting" and   a washed out appearance. The problem appears to be reagent 
carry over as it usually starts occurring about 2 to 3 runs after all of the 
reagents are changed. We have had the machine serviced and checked numerous 
time without solving the problem. 
Has anyone else encountered this problem with their Leica? I would like to 
hear from anyone with suggestions or comments.
