Xerox Phaser 7400/DXF Laser Printer Logo
Posted on Mar 27, 2009

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

I have a Phaser 7400 and when I print something, there's a faint dark line that runs horizontally across the page. The line isn't as obvious after several copies have been printed, but it's still there. Do I need to call a tech person and have it worked on, or can I fix it myself?

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.

My Ricoh Aficio CL2000N is printing several faint lines

Couple possibilities:
Fuser hot belt has wear lines transfering to the page
Black pcu needs to be replaced
Transfer unit is not being cleaned properly and needs to be replaced.
Remove each of these assy and inspect them for wear or lines that corespond to the lines on your prints.

A faint line shows up down the middle of the page, when printing a photo

from cnet review of the product

  • Unfortunately, as with the Z1420, fast print speeds come at the cost of print quality with the Z1300. Black text prints, though nicely dark, were beset by obvious jaggedness. The color graphics print had a slightly faded look to it and color blocks showed graininess and faint horizontal striations. Barcode-style patterns were muddled, too. For our tests, we printed color 4x6 photos with the standard black and tricolor cartridges, as Lexmark did not include photo ink tanks with the test unit. The colors were dull, details were hazy, and again, the entire print was marred by graininess and faint horizontal lines. That said, nobody buys a $25 printer to print photos for framing or to create displays for a classroom science project. A $25 printer is a convenience item for occasional reference prints, and as such, the Z1300 does its job.

Faint lines on printing

Keep running the nozzle cleaning. It should eventually sort itself out. Also try aligning the print heads.

Black ink is faint

First I would suggest performing any head alignment functions with your printer's menu to be sure you have the stepper motor feed adjusted properly. Use the paper you are currently printing on for this procedure so that the thickness of that paper is factored in.
If you stil see the banding after doing this, you can use the Advanced Media Control button under Printer Settings in ColorBurst to fine-tune the paper feed adjustment. Print out the "Media Advance.tif" target (located in the ColorBurst/images & Targets folder) to use as a guide. For white bands, you'll need to enter a negative number (to shorten the paper feed).

Dirty printing job

Are they lines from one edge to the other in a straight line. Or is it faint reprint across the page?
Thin lines would most likely be a bad drum or cleaning blade.
If it is faint reprint it is the heat roller in the fuser.
