Hi , and welcome to the HP Forums!
I see you are having troubles with your Officejet 6700, I would be happy to help you work towards a solution. Based on your description, it sounds like you are experiencing a quality issue. Does this issue present itself when you copy something from the printer, or when you scan something from the printer to the computer?
If you are experiencing an issue with scanning to the computer, are you initiating the scan from the front panel of the printer, or from the software on the computer? Also, what scan software are you using to scan from?
If you are copying something directly from the printer, please perform a self test page from the printer, then copy it to compare the quality. You can use the following steps to print a Quality Diagnostic page:
- Source
- Please place this page on the scanner glass and perform a copy.
Also, do you have the printer connected directly to a wall outlet or is it in a surge protector or power bar? Even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector
In this document you will see, ISSUE: Problems or issues may arise when an HP LaserJet series printer is connected to an uninterruptible power supply (UPS), a power strip, or a surge protector
^ This is not limited to Laserjet printers.
I look forward to hearing back from you!
