This printer has about 200K pages on it. I replaced the swing plate assy. and the gear on the fuser. This proceedure went well thanks to the Printer Techs instruction set. The printer now feeds paper very well. The test cartridge they gave me was a refill and it was putting extra toner on the page. The first page will always have a band of extra toner on top of the normal header for the page about an inch and a half long. After a few more pages to work out all the extra toner the rest of the job will print fine. Much to my chagrin the brand new HP toner cartridge does the same thing. It is only the first page printed that does this. When I start up the next job I always get the same result. The customer does not have a spare printer that I could use to try swapping some parts. This is not part of the normal inventory of printers that I work on so my resources are limited. Help me Obi Wan Kenobi, you are my only hope.
