HP 3050 Black Line

Right now the printer prints a single straight vertical black line down the center of the page along with what is supposed to be printed. How do I get rid of the black line.

I was getting a verticle black line and I had to clean the glass, the long white bar above the glass, and the white and black rollers before my problem was solved.

Did you copy or print from computer? if on copy time only, you must clean scanner bail, if for both ( copy and printing)your toner is damaged maybe.

Black vertical line when copying a book page.no light leaks.


If it is along the edge of the print, it may be the edge of the book page you are seeing. if it is going through the text of the page, your scan carriage is likely skipping. If you don't see this on copies of single sheets of paper laid on the glass, then the weight of the book may be deforming the glass enough to catch the scan carriage as it passes. If you see it on single copied sheets, there is probably something on one of the scan rails under the glass that the carriage is "hopping" over as it passes. You could try watching the scan carriage move while holding the lid open to see if the carriage "hops" once during a scan.

The fuser is located in the back of the printer. I think it's held in by to screws. It's about hte same size as the toner cartridge. Please visit these websites.

This is the fuser kit.

Printing black line when coping


You may need to replace the toner cartridge or the fuser assembly.

If you open the toner cartridge door and see a black line on the roller, you will need to replace the cartridge.

Black line along the right side near the center when copying ONLY


first, the line are in all printing pages, or only when you make copies?,
if the line are in all printing pages, maybe your fuser has damage the fuser film sleeve,(aprox, 10-20 dlls), if only this line are when you make copies, maybe the glass in the scanner are dirty(clean and try).
i expect this solution your problem

Print outs are having blck lines , what is required to be done


Its probably due to the roller, which are supposed to be changed every so often anyway.

With use, the rollers become scored/worn in places. The excess toner powder that is not used in the printing process is removed by a rubber blade. When the roller becomes worn it isn't wiped clean by the blade ... and you get that characteristic black line down the paper.

Change the roller. You'll probably pick one up on ebay.

Thick black line on printed page


If the line runs the way that the paper does I.E. vertical on a portrait then it is dirty rollers normally.
If you open the lid and wipe the rollers this shoukd reduce or eliminate the black lines.

HP 3050 vertical black lines during fax


OK, from the desciption i can assume several things here are some option.
If by receipt you are talking about the confirmation the unit prints the the problem is likely dirty glass.
You would also get the lines when you make a copy using the ADF.
Open the lid there are two areas of glass the thin strip is likely dirty and needs to be cleaned.

If by receipt you mean pages you receive from someone else, and not printed or copied on your machine, then their machine has the condition described above.

If everything has the lines then you have a toner or fuser problem:
This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the smudge or marks on the page the problem is most likely the cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

Vertical lines in scanned documents


Scan glass has muck on it, needs to be perfectly clear, it is just in where you feed originals.
