Why does lines appear in my printed copy? - Lexmark X1150 All-In-One InkJet Printer

Run the "clean inkjets" routine followed by test pages until printout appears correct. Maybe the print cartridges are defective.

Print quality is good, b&w copy is good. When i make a color copy the machine makes blue lines or bink lines. This is a brand new c452.Scan to PC is ok, print its ok only copy. Lines are vertical.

CLEAN THE LASER GLASS

clean or replace the "photoconductor kit" this usually connect with your toner

1. To test, print the Help List:a. Press the REPORTS key located on the control panel.b. Press the up or down arrow key until Help list appears on the display(#2).c. Press Ok. The report should begin printing.Black lines that appear on faxes you send, images you scan into the computer and copies you make are typically caused by dirt or white out on the scanner unit. The scanner unit is the mechanism that reads in the documents that are being copied or transmitted.

Replace the drum unit

Is it a white or black line?There can be a piece of paper in the drum cartridge or the drum is damaged!Scratched!Try replacing the drum cartridge!Good Luck!

I have the exact same problem. It was there since I first bought the MFC-7840W.
Vertical line appears in scans using the automatic document feeder (ADF).
Vertical line does not appear when scanning single page (placing it directly on the glass -- i.e. not using the ADF).
Cleaning the glass strip for the ADF (or the white pressure bar overhead) does not solve the problem.
The problem does not occur with copies using the ADF (using the COPY button which is basically a scan and print). This would suggest that dust and dirt is not to blame because that would also appear on the copies.
But since I believe a copy is basically a scan plus print, they should be using the same electronics -- a hardware problem on the scan would likely appear on a copy also -- there is some difference between how they accomplish this.
It's definitely not a software issue since it occurs on all versions of Windows and Mac OS X (and multiple computers). It also does not matter whether I "push" the scan to the computer by using the scan button on the MFC... or "pull" the scan from the MFC using the Brother Control Center software.

if the line is from the button to up must change the cleaner or you do the trick of cleaning it by any alcoholic liquid
and if the line appear only in the printed area so you must change the drum

Although you didn't specify the scanner model, this solution should work.

If the scanner has a top feeder, open it.

You will see a thin strip of glass, either to the left, or right of the large scanner glass.

There is most likely a small spec of ink, white out, etc on it.

Clean the strip glass with rubbing alcohol and the line should go away.
