HP LJ 4250 printer printed great - then started printing blank pages followed by a page with three or four horizontal thin lines spaced every 95MM. Easy fix! [So I thought] 

1. Changed the HP 5942A toner cartridge with proven working HP 5942A toner cartridge - three times out of working HP LJ 4250 printers. Nope. Same exact non-image and then horizontal lines. 

2. Changed HP fuser with proven working HP Q5421A 110V fuser - 3 times out of working HP LJ 4250 units. Nope. Same exact non-image and then horizontal lines. 

3. Changed the Laser Assembly. Nope. Same exact non-image and then horizontal lines on paper output. 

4. Changed the Transfer Roller with new RM1-1110-CLN HP Transfer Roller. 

5. Switched out paper with a working / printing HP LJ 4250 without any change. 

NOTE: No error codes at all. None. No funny sounds. Unit seems to operate normally other then as described. 

Help.
