Hello, thank you for using Howly.
Vertical lines on copies or scanned documents are typically caused by dirt, ink, corrective fluid, or other debris stuck on the ADF scanner glass. Cleaning the ADF scanner glass properly should resolve the issue.
Tell me please, did you try to clean your Brother printer?
Yes, I cleaned both glass strips of the auto doc feeder
Got it.
Let's determine if the black lines appearing on your documents are related to the printing or scanning area.
You will need to print a Test page.
Keep me posted on how it is going, please.
Test page is clean
I take that back...
There appears to be some VERY light black smudge looking marks
So it's not as clean, right?
Correct
Could you please specify one thing for me, are there black verticle lines on it?
Test page marks are in a vertical pattern, yes.
It is not a "line"
Got it, thank you for cooperating with me!
In this case we need to perform a manual drum cleaning.
The items required for this cleaning are:
- An alcohol swab, such as a medical alcohol pad or wipe, which can be found in a local retail pharmacy or first aid kit.
OR
- A cotton swab lightly moistened with isopropyl alcohol.
Will 70% alcohol be enough?
I think it's okay.
Alright. Let me grab what I have
Sure, take your time!
Ready
So let's get started.
Our toner is 4 separate cartridges. I have pulled the 4 out of the printer
Step 3 should look like this:
drum unit is what is attached to the replaceable toner or the piece that sits in the printer underneath all of the cartridges?
The drum is combined in the same cartridge as the toner.
ok. they are cleaned
Got it.
That seems to have worked splendidly! Thank you so much!
Oh, now there are no lines?
No lines!
Amazing!
I'm so happy I was able to help you.
Is there anything else I can do for you today?
That was all we needed. Thank you so much!
I am so pleased to see your issue got resolved!
