Printer quality

[bootk002]

I cannot get rid of the blue vertical line on the page. It happens when I print in color and black and white. I have run several cleaning pages and the problem still persists.

Hi @bootk002,

Welcome to the HP Support Community.

Thank you for posting your query. I will be glad to help you.

A persistent vertical blue line that appears in both color and black-and-white output is commonly linked to scanner glass contamination, dust inside the scanner glass, miscalibration, or scanner glass damage on supported HP large-format scanning/copying devices.
 

What to try:

Clean the scanner glass plate and the original:
 

• HP notes that vertical streaks/lines are often caused by dust particles inside the scanner.
   
• Clean the scanner’s glass plate and then try the job again.

Calibrate the scanner:
 

• If the line remains, recalibrate the scanner.
   
• Make sure the maintenance sheet is clean and not damaged before calibration.

Inspect the scanner glass:
 

• If the line still appears, visually check whether the glass plate is scratched or broken.
   
• If damaged.

Clean inside the glass area if needed:
 

• If the issue continues, HP indicates there may be dust particles inside the glass plate, which may require careful internal cleaning.

I hope this will help.

 

Take care and have a good day.
