vertical rainbow lines on print and scan jobs.

I am getting vertical rainbow lines on print and scan jobs.  I have tried a Print Quality Diagnostic and it came out fine.  I have tried shutting my printer off and waiting to retry.  I have never had a problem with my device.

@melo2480,

Thanks for engaging in the HP Forums! I will certainly do my best to help you 🙂

I understand you are getting vertical lines while scanning with your HP Envy printer. Don't worry we'll work together to help you find a solution.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Does that Scanner bulb light up?

Does the scanner bar move when you open the lid & press the copy button?

Have you checked if the unit can make a standalone copy? If ‘YES’ then it means the scan hardware of the All-in-One works fine.

Let’s first perform a hard reset and connect the printer directly to the wall outlet.

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer. (It’s important because 8600 has an internal surge protector & won’t work well with an external one)
• Turn on the printer and wait till warm-up period finishes and the printer is idle.

If the issue persists, check the figure below and clean thoroughly the numbered regions. That should definitely get the issue fixed. For more details, click here for instructions.

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

If this is the same problem I'm having it's not contamination in the scan window. It is completely corrupted. There are numerous reports on the forums for this and the only advice HP seems to give is to clean the window and power cycle the unit with little success.
