Question about Office Equipment & Supplies

Open Question

HP J6480 has very grainy, smudged document scans AND copies.

When scanning documents, I get very grainy, streaked and smudged scans with a dark band across the short axis of the document. Copies come out with the same streak pattern, so I thoroughly cleaned the glass but with no better results. Increasing scan resolution did not help and I could not fix the images by tweaking the settings in the HP Document Manager program.

Any suggestions?

SOURCE: Vertical Light Streaks on text documents, both single and duplex

Clean the glass thoroughly using Isopropyl alcohol. Dont use solvents. Check if there is any scratch on the glass. Repeated scanning with stapler pins can scratch the glass. If it is scratched, you may need to chage it.

Why is the photocopy and scanned document coming out dark and unreadable?


Hi there, my name is Lisa and I'd be happy to help you with your J6410. I understand your copies and scans appear dark and unreadable. Although you may not be seeing vertical bands, lines, or streaks through your scans and copies, I feel the following document might help you to troubleshoot the issue you have described:
HP Officejet Flatbed Scanner All in Ones With ADFs Vertical Bands Lines or...

Since the issue occurs when you perform both copy and scan tasks the issue is somehow related to the hardware and not to the software. 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.

If the issue persists, what you can do, is use the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Open link: h22207 www2 hp com
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.

I hope this helps.
I work on behalf of HP.

How do I fix a dark streak down center of scanned document on HP laser jet 3330


Hello,

Lines and streaks are usually caused by ink or trash blocking the scanner pickup. You need to open the top of the scanner and clean the scanner glass. Here is a link to a guide that shows where to look for something blocking the sensor.

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

It seems like part of the light on the copier has burnt out...can the light be replaced? I get a thick dark streak in a copy or scan but not when I print something. Have replaced ink and aligned...


Light is not burnt out.
Open the feed in section where you feed the documents, and clean the glass that documents are scanned across. It is simply dirty

Scanning document leaves streak down right hand side


Even a single grain of dust or a single strand of hair on the scanning glass will cause the scan head to perceive ink/image where there is none. Deffinetly try cleaning the glass using a good window cleaner, and a cloth that is completely clean, or even a peice of newspaper. If the black line remains, I would suggest taking it into a service center to have the scan head itself cleaned.
