Thin vertical black line always is printed on the left side on A4-format paper

[jonasmahieu]

Every time I print on A4-format paper any which document (like Word .docx or PDF .pdf) on my HP Officejet Pro 7740  printer, a thin black vertical line at the utter left side (approximately 2,5 mm form border) is printed on all pages, except for (some of) the last page(s). This is very annoying for professional use. Can you please help me? I already tried every single step of troubleshooting and HP Print and Scan Doctor.

Hello @jonasmahieu ,
Welcome to the HP Support Community!

Print the "printer status report",

to print a printer report

1. From the printer control panel, touch or swipe down the tab at the top of the screen to open the Dashboard, touch ( Setup ).
2. Touch Reports .
3. Select a printer report to print.

scan and upload here, click on the icon "Insert photos", "Set format = Large", original size at least 200 KB.

But before you upload, you must remove or delete the personal data and printer serial number on the printout.

Andreas

The printout is OK.

I suspect this line is not generated by the printer, but transmitted by the document (docx, pdf) itself.

upload an example here, click on the icon "Insert photos", "Set format = Large", original size at least 200 KB.

It looks like the cause of the black line is a scanned image. This image was inserted into the Word document.

1. Did you create this document yourself in Word?
2. Or did you use a template (from the Internet)?
3. Is this line already visible with the Word print view?

1. I created/drafted my own Word document in Word without such a thin black vertical line. The field/object in Word is purely blue.

2. No template was used thus.

3. This line does not show in Word print view nor in the PDF output file.

Make a test:

open word

new dokument

press 1 time the blank key

save this dokument "test.docx"

open test.docx

print it

did you see a vertical balck line?

[jonasmahieu]

I did as you suggested.

There is no thin black vertical line printed on "the blank key Word document".

I seems to me when the objects/text is positioned very close or on the border, such a black line is printed. But I'm totally not sure about that.

Thank you for your (further) assistance.
