I am here asking for help in troubleshooting the issue I am dealing with my Xerox 6204. Couple of months ago, the copier started copying and printing white lines across every copy/print. We replaced the magnetic roller and cleaning blade however the issue was not resolved. In the troubleshooting process, the user console broke and we had to replace it as well. After this, the copier started printing/copying everything blank. We tried replacing the LPH assembly as well and this didn't resolve the issue either. Any help would be appreciated thanks.
