Question about HP LaserJet 3050 All-In-One Printer

1 Answer

When copying or printing, the center of page is mostly blank with very faint printing visible. It leaves a vertical, whitish area from top to bottom of page. This area is where the rollers are. The left and right sides take the toner well and print fine.

Most problems related to printing and printout is caused by the Drum and in rare cases Cartridges. But since your print-out isn't visible or having faint inks, and have proportion on a particular part on the paper, i suspect the drum. First try this.

Open the door which covers the cartridges and drum (front door) while the printer is still On. Take a soft feather (of you can use soft-brush), wipe the cartridge's bar (transparent glass rod smeared with ink). Also wipe the drum's bar (blue glass rod) with another feather/soft-brush. Close the door, again open it and wipe them once again. Now print a copy, if you see any changes, then you need to clean the drum and remove the waste ink from the waste ink tank. You'll need to disassemble the drum to do this. It's risky and you may damage it if you haven't done yet. If you are new with it, I would not recommend you do that, rather call a tech or experienced friend and let him/her do it for you so that you can copy what he/she is doing with it and how the waste ink tank is cleared.
For laser drums, instruction isn't sufficient to disassemble and assemble it, without experience, you may damage the expensive drum.

It would be much helpful if you have spares, drum or cartridge so that you can try with another. Even cleaning doesn't clear the problem, you need to replace the drum which means you need to buy a new one and install it.

I wish you all the best.

Thanks for using FixYa.

Scanner leaving black streaks


There are two possible fixes.

Download the latest firmware update by CLICKING HERE

The following is provided by courtesy of Lexmark:
Problem Vertical lines; Auto document feeder scan anomaly; ADF scanning problem; Scan issue; Scanner issue; Visible line; Streaks show on page; solid line down the page; Top to bottom line; Smudge runs down the page; Opaque line; Broken line; Bar all the way down the page Solution Overview

This article provides the self-diagnostic steps necessary to evaluate top-to-bottom streaks that appear when copying or scanning.

Important! This is seldom a scanner hardware failure.

The main reason for this anomaly is debris or marks on the scanner glass that is used for Auto document feeder (ADF) page scans.

Printed or Scanned Page Illustration

copyvertstreaks.jpg

Who should consider this article?

Any user of an MFP or All-In-One printer experiencing the following symptoms:

  • -Vertical lines only when using the Autodocument Feeder (ADF).
  • -Observed with any type of scan job (e-mail, ftp, solutions, fax).
  • -However, normal expected output when the page is scanned from the scanner flatbed.



ADF scan behavior

Think of it this way:

  • -The page is pulled from the ADF.
  • -The moving page slides across an ADF-designated portion of glass.
  • -The image sensor, which is located under the glass, reads and interprets the moving page's contents.
  • -Contamination on this ADF glass is seen by the image sensor for the entire length of the page.
  • -The image processor interprets the image sensor's repeated capture of this contamination as a vertical solid line.
  • -Any ADF scan function now exhibits a vertical line.

Suggested Diagnosis and Fix




Step Action 1 Locate the portion of the glass designated for ADF scans.
HINT: The glass location differs by model. This area is often separate from the scanner flatbed. Please reference User's Guide for more information if you are having a difficult time locating this designated area.
2 Perform a visual inspection for any of the following recurring culprits:

  • -Clear adhesive tape
  • -Glue
  • -Ink pen
  • -Paper
  • -Marker
  • -White out
  • -Staples
  • -Environmental dust or dirt
HINT: Ink marks can be especially hard to see and almost translucent at first sight. However, the image sensor (CCD) registers them as a mark. 3 Use a clean, soft, moistened cloth to thoroughly clean and remove any marks or debris. 4 Inspect the underbelly or underside of the ADF for any marks or debris. 5 Perform another scan to see if cleaning the glass alleviated the issue. 6 Repeat the procedure if a vertical line still appears.
Remember! Printing and scanning from the scanner flatbed work fine.
7 This time, place an intentional mark on a blank sheet of paper and take note of its location. Now place that sheet of paper in the ADF and make a copy.
8 Evaluate the distance of the vertical line to the your mark. 9 Inspect that area of the glass for further debris or marks and clean as necessary.

When copying or printing, there is a whitish strip down the center where the rollers are. Print in this area is very faint. Thank you for any advice.


Remove the toner cartridge and while keeping relatively level, shake it from side to side. Re-install and try a test print. If the light band has gone away then problem solved. It does mean that your toner crtridge is probably starting to get low on toner. 90% of the time, print quality issues on HP lasers are toner cartridge related.
Good Luck and Thank You for using Fixya.

I have a X7170 it has recently began printing with vertical blank areas on the printed copy. In other words up and down on the page there missing copy. I have changed ink cartridges and this does not help....


Uneven vertical lines can be adjusted by
performing the printhead alignment adjustments.
The user is directed through the Lexmark Solution
Center to perform the printhead alignment
adjustments when replacing a printhead cartridge.
The alignment can also be performed from the
control panel by selecting the Maintenance Option,
then Align Cartridges.

Dell 1600n: Toner marks down the center of the page.


There are 2 seperate glass areas on the top, the large one is for when you lift the cover to scan or copy, the little narrow one is when you use the ADF. If there is a dot or a spec on the narrow part, it will leave the streak on the page, Clean the narrow part really well. I use a foaming window cleaner, and a razor blade.
You may also want to check to see if there are any small scratches on that glass. That will cause the same thing to happen.

Consistent, faded and streaking vertical lines across entire page, from top to bottom.


Toner issue getting to drum - use gen toner cart.

or Drum blade stuffed (lines are down page fro top to bottom- replace drum assy

Drum has been exposed to light faint or blank across copies repeated 4 times down page - replace drum assy

or upper fuser roller stuffed, down page, smudgy print -  replace fuser

LSU(laser) or boards rarely cause issues

Why do I get a line of faint or no copying on the page?


Does this blank line run top-to-bottom or side-to-side, and which direction is the paper traveling through the machine, portrait or landscape?
