Are the lines vertical or horizontal?

vertical lines can be caused by several things.
Since you said that cleaned the rollers, then here are other options
1: Most common is a bad toner cartridge.
2: try cleaning the fuser entrance guide.
3: could be a defective formatter - formatter replacement the fix.
4: worn fuser. fuser replacement is the fix.

horizontal lines are probably repetitive down the page, and are usually caused by a defective toner cartridge or fuser assembly. occasionaly a transfer roller will cause it as well.

Toner loves to get baked onto the fuser and cause all kinds of print problems. Not much you can do but to replace the fuser when this happens.

Printing not dark enough or varied in darkness
If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.

Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.

If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.

Horizontal black lines
A horizontal black line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant black lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
0.5”
Registration assembly
1.5”
Upper registration roller
1.75”
Lower registration roller
2.0”
Toner cartridge developer roller
2.56”
Lower fusing assembly roller
3.16”
Upper fusing assembly roller
3.75”
Toner cartridge photo drum

Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.

Vertical black line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

My Dell 1720dn mono laser printer has not printed properly for some time - in fact it's dreadful! The letters and dark images have white vertical lines going through them, and some of the printing do


Change your toner cartridge. A properly working toner cartridge will never leave that much toner lying around. The white lines are an indication that either the toner is low, or the mag roller is defective.

HP Laserjet 5P shading edges of page


This is probably due to a defective cartridge, Charge Roller or Transfer roller.

Check the cartridge for a band of toner still on the drum.

Check the Charge roller for oil or smudges, this roller should be a lighter color and should be relatively free of toner or marks.

Same as the Transfer Roll, which will be dark, though excess toner should be evident.

A relatively smooth straight line is generally the cartridge.

A rather wavey or broken line is most likely the rollers.

You can however attempt to print a large amount of pages (25-50) in an attempt to clean the parts, however if either part is defective they will need to be replaced and no manner of printing will clean them.

Black lines on the right side of every copy


depending on what the lines look like it could be the charge roller or transfer roller.
A defect on the charge roll appears as black areas on the front of the test page, and as light gray areas on the test page.
A defect on the PC drum of the toner cartridge appears as white areas on a dark, full–coverage test print and as black areas on the "text only" test page.
I have also seen a line with a 'ridge' on the paper. This will appear almost like an embossed line. This was caused by the fuser roller being scored by debris.
