I have a Olivetti d copia 3013 which is the same as a Kyocera FS1128. The machine had come into the workshop for servicing and change on drum and toner. Upon changing the drum and toner I noticed that the copies were light. I tried darkening it by the normal ways (going into system menu and changing the darkness) but that didnt help.

In a last try I entered the SP Mode and did a factory reset - Service Mode number U021
Machine thereafter went into a cycle and stopped but now only produces blank copies. Ive checked other setting but I am having no luck with correcting this fault. I also checked the scanner lamp which is coming on and moving across to scan.

Can someone please help !

Once again, machine copies blank but can produce an internal printout like Status Page or network page.

Thank you
