SOURCE: copies print with horizontal lines

thin lines? spaced about 1.5 inches apart could be toner left on the drum, take the cartridge out turn it over and retract the shutter, manually turn the drum using your thumbs on the edges of the drum, do you see thin lines on the drum? sometimes something sticky gets on the drum attracting toner and then it transfers to the paper during the copy process

SOURCE: Horizontal line print errors

  1. Hold the cartridge upside down, with the bar-code label facing you.
  2. Take a damp paper towel and use it to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
  3. Continue doing this until the printhead looks clean.
  4. Then dab the cartridge on the towel to make sure the ink is flowing.
  5. Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.
    1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
    2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.
    3. And then perform This

  6. Press the Mode button on the operator panel until the Copy light comes on.
  7. Press the Menu button once to enter the menus.
  8. Press the down arrow button until you see Clean Cartridges.
  9. Press Select. The 'Clean nozzles' page will now print.

SOURCE: Faint horizontal dark line about 2 1/8 inches down from the top

Hi,

You can easily fix this yourself, one of the quickest ways to fix it is to print 10 doublesided blank pages and it will clean the inside of the machine for you and the line will vanish.

For further print quality problems on this machine follow these instructions to troubleshoot.

When troubleshooting image quality problems, it is important to understand the situations in which the problem occurs.

Print a copy of the color test pages to determine whether the problem is in one color or more than one color.

  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Color Test Pages], and then press the [OK] button to print the test pages. If the problem occurs with one color on the test pages, perform the solutions for this problem. If the problem occurs in more than one color on the test pages, restart your search and select a case for the image quality problem occurring through all colors.

SOURCE: hp 2500l prints a dark line horizontal down each

A dark line on the hp 2500 series can come from the drum You can't clean it at home), it can come from a toner cartridge, from the fuser unit and from the optics.
Step one - check if the line in all colors, run copy quality check through Menu and diagnostics, if the line is only on one color your problem is the toner cartridge.
Step two - if the line is on all colors, take the drum unit out and look at the drum, if you see the line on the drum you need to replace the drum unit.
Step three - stop a print in during the printing process by turning the printer off, take out the drum and look at the printed paper under the drum, if the printed page is clear of line your problem is in the fuser.
Good luck.

HP 7110 still won't print in color


Your post "...it prints very faint horizontal lines in color..." is indicative that indeed your color printheads are clogged and would need repetitive deep head cleaning. This is of course would require that you keep on cleaning until such time as the faint color lines have turned to legible print.
