white lines

[GretchenBB]

I have a HP Laserjet 1018 printer. I love it. But recently it started printing with white lines, similar to what one gets when toner cartridge needs replacing. So I got a new cartridge. Didn't help. I took it to an office supply place that does repairs. He cleaned it, and it didn't help.

I went to some HP fixit sites and tried some software tweaks. Increasing density helped a little but not enough.

Just downloaded current drivers. Didn't help.

Does anyone have any other suggestions?

Please most a sample. Might be a bad transfer roller.

Thanks. The guy who looked at it said he cleaned the transfer roller. He thinks it might be lamps or the board.

I don't know how to post a sample. It's vertical white spaces, the same as you get when you need a new toner cartridge.

I wouldn't think the transfer roller would be the cause, not for white spaces like that. Since you've changed the toner cartridge already, the next thing I'd look at would be the metal laser exit window and glass for any contamination on the glass or stuff clinging to the metal cutout for the window that would interfere with the laser beam inside the printer.
