Envy 7855 Shadowing Images Print Quality Problem

[SBaker71]

I'll start by saying I am at my wit's end. Full on meltdown. Let me explain.

Printer: HP Envy 7855 replaced an old HP Envy 7640

Purchase Date: Feb 03, 2021

Computer: Acer Aspire TC-895-UA91 Desktop
OS: Windows 10 64-bit
INK: Use only cartridges provided by HP Instant Ink.

Wi-Fi Router: TP-Link AC1750 Smart WiFi Router

How Connected: Desktop to Router via Ethernet (2 feet apart) - Printer to Router via Wi-Fi (20 feet apart)

Problem: Shadowing of image elements (see images). Inconsistent problem from sheet to sheet. Sometimes whole sheet; sometimes just a line; sometimes just the font of the image; sometimes the design of the image. Getting worse.

1. I make and sell personalized labels in Photoshop.
2. Import completed image into a Silhouette Cameo 4 template for Print & Cut.
3. Print from desktop.

What I've Tried

Everything! Multiple times!

• Everything has updated drivers and all software is updated.
• Cleaned Heads via HP Provided software before, during after (1-3 times)
• Changed to new color and black Instant Ink cartridges
• Changed paper type
• Changed paper print settings
• Used the HP Printer fix software multiple times
• Unplugged everything and restarted
• Used print quality tools
• No errors
• Completed the information posted for every printer problem
• Printed via PDF instead of software
• Printed one at a time to avoid using a queue buildup

The only thing I have not done is throw this POS out the window, and I am really close. This is the third attempt at a new printer with the other 2 returned because they were DOA. This is my small business and I am wasting literally hundreds of sheets of paper trying to get one that is good.

PLEASE help me. I am literally in tears and so stressed. I have tried everything I know.

Images aren't show on my end, so I am sharing via ImgBB.

This morning same thing. This time I bypassed the router. Again, after about 5 prints being fine, they all begin having random placed errors as explained above and shown.

Please someone?

@SBaker71, Welcome to the HP Support Community!

Thank you for the detailed post and information. I appreciate your efforts in trying to resolve this issue by performing the necessary troubleshooting steps.

I see that you have performed all the necessary steps and also replaced both the ink cartridges and yet the issue persists. 

Try making a standalone copy from the scanner glass and check if that prints fine. By this, we can conclude if this is a hardware or a driver issue.

If the issue persists, I'm afraid this is a hardware issue with the printer. Please reach out to the HP Technical Support team in your region regarding the service/replacement options for your printer. 

You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.

Keep me posted for any other assistance.
