This issues looking printer head problem. check the following Steps for cleaning printer head :

Click on the Start button if you have Windows XP. If you have Windows Vista, click the Windows icon that resides in the lower left corner of your computer screen.

Click on "Control Panel," then "Printers and Other Hardware." Finally click on "View Installed Printers or Fax Printers."

Right-click on the name of your printer and choose "Printing Preferences." This should open a new window; next look for a tab or button marked Maintenance, or something similar.

Find the button that says "Print heads" or "Clean the Print heads" and click on it. You may be asked to choose which print heads; choose them all if you are. Make sure there is paper and ink in your printer, and that it is turned on ahead of time.

Take out the page your printer has printed and see if there are any grids or boxes missing. If there aren't, then you can just exit the program--your print heads are not clogged. If there are grids missing, then click on the "Cleaning" or similarly worded button.

Once the cleaning process has completed, print another page to be sure that your print heads are no longer clogged. If they are still clogged, repeat Steps 1-5 until your printer is printing clearly.

When I scan two-sided to pdf, the back page has a large black vertical streak down left side.


If that is the last page that has the streak use a blank page in the original scan as the last page and then the dark line wont cover the image.

Vertical Lines through incoming faxes and copies.


Sometimes you may see vertical streaks/black lines
on the faxes you receive. Either your FAX/MFC's
primary corona wire for printing may be dirty, or
the sending party's fax scanner may be dirty. Clean
your primary corona wire (see pages 13-18), or ask
the sender to make a copy to see if the problem is
with the sending machine.
Cleaning the Drum Unit
We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering toner.
1 Carefully turn the drum unit upside down.
2 Clean the primary corona wire inside the drum unit by gently sliding the tab
from right to left several times.
3 Return the tab to the Home
position (  ) before
reinstalling the drum unit.

Sometimes you may see vertical streaks/black lines on the faxes you receive. Either your machine's
primary corona wire for printing may be dirty, or the sending party's fax scanner may be dirty. Clean
your primary corona wire. I recommend placing the drum unit on a drop cloth or large disposable paper

1. Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.
2. Return the tab and snap it into the Home position, (Caution: If the tab is not at the Home position, printed pages may have vertical stripes).
3. Reinstall the drum unit into the machine.
4. Close the front cover.
5. Plug in the power cord first, and then plug in the telephone cord.
or ask the sender to make a copy to see if the problem is with the sending machine.
Try receiving from another fax machine.
If the problem continues, call Brother Customer

My drum is at 40%. I have black vertical streaks


I was going crazy! Had a tech come in and look at the machine - needless to say he did NOTHING! A friend came over and was trying different things. It was that the "rack" that the toner cartridges sit in was not fully seated - once he pushed down a little and heard it "click" I had no more black streaks. AMAZING

CLP-500 vertical streaks & a horizontal line with blotches appearing randomly


I've refilled the toner cartridges a few times now and never had a problem with vertical streaks until recently. I refilled both the cyan and magenta and when I ran the test page I had dark vertical streaks on both sides. I fiddled around cleaning things, running cleaning paper through, changing reset resistors but to no avail so eventually decided to buy a replacement refurbished cyan cartridge since the streaks looked mainly blue and bingo... well almost now I just have very light magenta streaks. The issue is obvious when I compared the old and new cartridge, the replacement toner is a much duller cyan and is of the wrong consistency since once it's been in the printer everything gets covered in it which is why I think it causes the banding to occur. I'm just trying to work out now whether to try refilling the magenta again (v. messy) or just go for another refurbished cartridge (£34).

Minolta 2300DL Printer - black streaks


Hey Chuck, Any chance you can post a scan of one of the faulty pages ? This will make it easier to assess the fault. Print off about 10 pages of a page that is affected by the lines. Look at each page and see if you can detect a recurring pattern over any of the pages. If there is a pattern, chances are it is probably the PCU that is marked.

Minolta 2300DL Printer - black streaks


Without actually seeing a print sample or the machine, my bet would be on the black print cartridge. Even though it reads a an acceptable level of toner, the cartridge itself sounds like it has developed a proble. 1. It's the most obvious 2. It't the cheapest place to start. If it does not correct the problem, you can still use it later. 3. It's the problem in about 80% of these types of cases. 4. I know it should be fine, but if things didn't go wrong, I wouldn't have a job! Let me know. If not we'll investigate further. Ed
