Question about HP LaserJet 4L Printer
Black Horizontal Lines are normally caused by a Light Burnt Drum.
The drum in built into the toner cartridge for this machine so replacing the cartridge will fix the problem.

This is a very common problem with this model printer, it is caused by toner on the scanner mirrors. You need to clean the scanner assembly unfortunately it isn't very easy to dissemble the printer to get to it.

SOURCE: printer prints white thick blank lines
1- black lines are from the drum: it has burnt out on that particular spot and rotates
2- the white horizontal gap space if it is not you skipping space is also from the drum
3-the white Vertical is most likely from the developper (unit that has the toner and is against the drum, look at the roller it should be solid black, maybe there is something on it : hair paper etc....

SOURCE: lines across printed pages
Does the line repeat, if so tell me what the distance it between repititions. I need the EXACT measurment in millimeters preferably but inches will do.

yes you have to catch printer making the line and then as a page is being printed you need to open door to stop paper after green cylinder(drum) as it is entering fuser, then you need to remove paper from printer without pulling through the fuser, if you see the line then rub your finger across line up and down page, if it smears at all then its the cartridge if not then the fuser
