Check the fuser for signs of wear, if all looks intact, if the whole page is being coated, the problem is either with the drum in the tonor or the transfer roller

Tip

When u print if u r getting the Horizontal or vertical line then follow these...


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.

The pages on the right side come out faded or not printed at all. The printer is only a couple of years old, no more than 5-10k total pages printed. On second set of cartridges.


Hi

If its happening with single shade color
1) Take the Cartridge out of the Printer and shake it
2) Clean the cartridge drum with the Tissue Don't Rub slightly clean it
3) Take the Cartridge out and shake it
If page comes faded on every print Black or Color then there must be a Roller issue which is not clean
1) It could be the Roller side is not clean -
Need service for the Printer

Black Lines running down the right side outside of the print area


It may be the fuser. Take it out and inspect the roller on it:

  1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
  2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
  3. Open the front cover by pressing the release buttons as shown.
  4. Pull the front cover down towards you.
  5. Disconnect the green plug - squeeze the sides of the plug and pull.
  6. Push the left and right levers outward to unlock the unit.
  7. Pull the unit towards you as shown and lift it clear of the device.
  8. Check the roller for wear marks, If so replace it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Horizontal streaks on pages


Streaks at 2.82 inch intervals: Horizontal marks at this interval are the result of a mark on the fusing roller of the printer. In some cases, these marks can be cleared up by running a cleaning page through the unit. Laser Printer Cleaning sheets can be purchased at your local printer/office supply store. If the marks persist, this can indicate a more serious problem with the fusing roller that would require service attention.

Streaks at 3.74 inch intervals: Horizontal marks at this interval are the result of a mark on the image drum of the printer. There is no way to repair a damaged photosensitive image drum, so in the case that it is scratched or otherwise damaged, the entire CRU (toner/drum cartridge) would require replacement to clear up these marks.

Eadch line of text is slightly faded at the bottom from laserjet 1100


It is possible that the transfer roller needs replacing as this causes it. Have you recently wiped clean the black roller that sits under the toner cartridge if you have you may have damaged it.

Best thing is to replace the transfer roller very easy to do and not expensive.

Hope this works for you and please rate me
Thanks J
