When I scan a page the result has black streaks. When I print or fax the result is a nice clean page. How can I fix this?

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

I understand you are getting black streaks while scanning from your HP LaserJet printer. Don't worry I'll do my best to help you with this.

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?

Have you tried to clean the scanner glass and document feeder?

Did you try to make a blank copy from the printer?

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, Clean the scanner glass and underside of the scanner lid with a soft, lint-free cloth sprayed with glass cleaner.

1. Turn the printer off, then disconnect the power cord.
2. Lift the scanner lid.
3. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass, glass strip (if present), the white backing under the scanner lid, and the white strip under the lid (if present) until clean, dry, and streak-free.

CAUTION: To protect the interior printer parts, do not spray the cleaner directly on the glass or on the underside of the lid .

1. White scanner lid backing
2. White ADF scanner lid strip (if present)
3. Glass ADF scanner strip (if present)
4. Main scanner glass

Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

NOTE:

Some printers ship with a document feeder cleaning cloth. If you have the cloth, load it into the document feeder and start a scan job to clean the scanner mechanism.

1. Turn the printer off, disconnect the power cord, and remove the battery if your printer has one.
2. Depending on your printer model, open any top cover, document feeder tray, and scan document feeder cover.
3. Remove any debris such as bits of paper or paper clips from inside the document feeder.
4. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass and the white strip on the underside of the document feeder until clean, dry, and streak-free.

CAUTION: To protect the interior printer parts, do not spray the cleaner directly on or into the printer .

If the issue persists, try making a blank copy from the printer and check.

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.
