Error when burning CD

Have you ever get an issue when trying to burn some files to a CD/DVD?
In my case I got error writing Lead-In when trying to burn some file using UltraISO on my IBM T42 CD ROM (HL-DT-ST RW/DVD GCC-4242N). I can use it to read any CD/DVD with no issue.
I try to change the burner software to Nero but got similar error too. Try to lower the burning speed with no luck.
Previously I remember that I can burn a CD with that CD ROM, somehow it's just stop working.
I try to search for a driver update but cannot find any. A firmware update maybe available but I think that's too much for the issue.
Finally I try to clean the lenses. Just wipe it with a clean tissue, try to burn, and it works.
