Hp HP LaserJet 4

HP Laser Jet 4 printout problems

I replaced the fuser assembly, all rollers (maintenance kit), and installed a new HP Genuine Cartridge. My printouts have a grey background haze over most of the front of the page, and repeating horizontal black lines on the back side about 2-inches apart. Sometimes text ghosting appears on the front side. I used compressed air (dust-off) to remove as much toner dust before installing the aforementioned parts. Does anyone have a possible solution to this problem. Thanks, Jeff
Since they haven't made any new genuine cartridges in years, you have one that is way expired. The drum wiper blades which should clean off the drum and if they don't, will cause gray haze. You can take the cartridge apart and replace the wiper blade. Only 6 screws involved and less than 5 minutes work. We can supply you with a replacement blade. [email protected]

Hi Moe, I live in West Los Angeles, so I could stop by the shop sometime this week. If not, how do I order the wiper blade? What is the part number, and are instructions included? Thanks, Jeff - steamlocodog
Hey, come on down. We're there from 9-5. We'll fix you up with instructions.
