mfp 2127DW - Prints OK from computer but brints black over anything scanned except white.

[FGF1935]

Prints OK from computer except for about 1/2 inch light grey horizontal lines .  I can accept that but have trouble with with scans.  First scan will print page OK but a second scan prints  everything except white with black ink.     After a period of inactivity it will again scan 1 page OK and the next scan every thing in black.

Hi @FGF1935,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.
• What operating system is running on your device and the current version of OS running on your device?
• Does the copy work fine?
• What software are you using for scanning?

While you respond to that, Let's perform a power drain: 

• 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 (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
