Variable scan quality with HP Envy 4501

I see my scan quality is variable on different days. Sometimes the same scan comes across granier than other days. I then try restarting unplugging reinstalling printer etc. Works sometimes, sometimes does not
Any clue what's going on?
See these 2 examples. You see a certain graininess in the second image

Hi @sidpri,
Welcome to the HP Forums!
I understand that you are getting variable scan quality with your HP Envy 4501. I am happy to help!
I would suggest, to make sure the printer's power cable is plugged directly into the wall outlet, and not a surge protector, Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
Also, to make sure the firmware is up-to-date. Getting Printer Updates for HP Deskjet Ink Advantage 3540, 4640, HP ENVY 4500, and HP Officejet 4630....
Another option is to go through this guide, Unexpected Scan Output Using HP Scan Application for HP Multifunction Printers When Using OS X v10.9.... (This guide will work with Mac OS X 10.10 as well.)
Hope this helps, and thank you for posting!

How do I Scan Document to MS WORD With HP ENVY 4501

How do I Scan Document to MS WORD on HP ENVY 4501

Hey @LarrySr63 ,
You can not scan to Microsoft Word. You scan the document as a specific file (PDF, JPEG or TIFF) to a storage directory on your computer that you can then open later in Microsoft Word. Remember, when scanning you are saving the document as an image and you need special programs to be able to edit those documents.

Printing from another device to the HP Envy 4501

We purchased this printer because we were supposed to be able to communicate with all of our devices. We have a laptop that can print to the printer, but we are unable to scan from the HP Envy 4501 to that laptop. It only wants to scan to our desktop, but the printer was only set up as a wireless printer (no USB's). Are we able to scan on the printer to any device and if so, how do we get this set up and enabled?

Hi,
You may have to start from your computer first:
    Double click printer icon on desktop,
    Select Manage Scan to Computer
    Click Enable -
You can start this automatically with Windows BUT you will get an arror message if you turn on the computer BEFORE the printer.
Regards.

HP Envy 4501 printer jams

I bought this printer on black friday and had nothing but problems with it since I got it. Every time I try printing it jams. I have normal paper in it so not heavy or anything but cant figure out why it keeps jamming. It also says offline most of the time when I try printing wirelessly. PLEASE HELP!

Hello jhartwig.
Welcome to the HP forums! I understand your concerns with your Envy 4501. Please follow this entire HP document on 'Paper Jam', as this could resolve your issue.
What is your operating system on your computer? Windows or Mac.
Please follow this HP document on 'Printer is offline' Message Displays on the Computer and the Printer Will Not Print.

Looking forward to hear from you.

How do I scan multiple pages into one pdf document on a HP Envy 4501 Printer

My HP Envy 4501 Printer won't let me scan multiple pages into one pdf document.
I went to "Advanced Settings", clicked on "file" and made sure that the check box next to "Create a separate file for each scanner page" was unchecked.
When I clicked the Save button it showed the page that I scanned and showed 1/1. On the right side it had options for changing the brightness and Contrast, Rotate and Crop and "Back", "Save" and "Done" buttons, but nothing about scanning another page.
Not to mention HP's Customer Support is useless!
I'd appreciate any help I can get with this problem.
Thanks,
Mark

Hi BH,
I see your diagram. I just scanned something. The screen that I'm looking at right now shows the preview page and the scroll box to the left of that just like in your diagram. The screen does not show the + button nor does it show the red x button under the scroll box as in your diagram. I can't see the plus sign because it is not there.
I tried re-installing the software and drivers as you suggested but that did not have any affect.
Thank you for trying to help me with this problem but it hasn't worked, therefore I can't mark the reply "Accept as Solution".
I've noticed that on HP's support forum web page there is only 1 solved request for assistance. That doesn't give me much confidence in HP.
Please reply back to this post to let me know if there is anything else that I can try or if you know someone else at HP that can help.
If I don't here back from you, I'm returning this HP Envy 4501 Printer to get my money back to use it to buy a printer from one of HP's competitors.
Thanks,
Mark

HP Envy 4501 won't scan multiple pages into a single document

My HP Envy 4501 Printer won't let me scan multiple pages into a single pdf document.
I already made sure that the checkbox "Create a separate file for each scanned page" is not checked under the file section in advanced settings.
After I scan the first page, I do not get a screen with a + (plus sign) that is supposed to allow you to scan additional pages into the same document.
Is there any way that I can get a fix/update for my HP Envy 4501 Printer software that would show the screen with the + (plus sign) that allows you to scan additional pages into the same document after you scanned the first page?
At this point, if I don't get this problem fixed soon, I'm about ready to return my HP Envy 4501 Printer back to the store I bought it from so I can get my money back and buy a printer from one of HP's competitors before my store warranty runs out.
I am very dissatisfied with HP's printer software, their support services and their web sight that doesn't work half of the time.
Thanks,
Mark

Why doesn't HP Envy 4501 scan look like a real photo when I scan a photo

I was trying to scan a photograph using the new HP Envy 4501 printer/scanner. However, not only does some of the photo scan in pieces, none of the photos (I've tried different dpi's from 300 clear up to 1200) look like a photography when you open up the file. I have also tried making them .bmp, .tif, and .pdf. I never had this issue with my old Dell printer but if I can't get a photograph to look like a photograph on the HP Envy, I will have to buy a different printer.

Hey there ! Thank you for posting on the HP Forums! I should be able to lend a helping hand regarding the scans coming in pieces. The first thing I suggest is to scan using a different program such as Microsoft Paint. This will be a good way to see where the issue is coming from. Open Microsoft paint by clicking on the Start icon and typing Paint in the little search bar. It should be the first one that pops up. Once you have paint open press the file icon at the top left corner and click on "from scanner or camera". Select you scanner and scan the image. See if it shows up in pieces. Please post back and let me know how it goes!

Poor image quality when scanning coins with officejet pro 8600 plus

I recently upgraded my printer from an HP 2210 to and HP officejet pro 8600 plus. image quality on coin scans is terrible.
I have tried scanning both with the HP software and with windows 7 fax and scan software
I have saved images as BMP, JPG, PNG, and TIFF
I have used resolutions from 300 dpi to 1200 DPI
All give me similar unacceptable results.
Images are better when scanned flat on the scanner than when in slabbed holders, and from this I am guessing that the plastic is somehow interfering wiht the scan. Either that, or there is a very shallow depth of field so that even moving the coin a few mm away from the glass moves it out of focus. But even a raw coin placed directly on the glass has significantly worse image quality than the old 2100.
The first image is a coin scanned with the old 2100. The second has been scanned in a similar slab by the 8600

Hi terry_renee,
Welcome to the HP Forums! I am happy to help you with this scanning issue! I did a test with an HP Officejet 8600, at 1200 dpi, and no plastic covering. Just the quarter on the glass, and we cropped it to the quarter. This is the result.
I have a few questions for you:
What Operating System are you using for scanning? Windows or Mac? What version?
What scanning software are you using?
Are you scanning from the computer, or the printer's control panel?
Hope to hear back from you, and have a great day!

Hp envy 4501 does't print just leaves blank pages

My Hp envy 4501 doesn't print. It just makes printing sounds then the page comes out blank. I just put in a new ink cartage in the slot. Please help. I need to print out my large essay. My model number is SDGOB-1301

Hi there @Heyitsdavid !
Thanks for contacting the HP Forums!
I can see by your post here that after installing a new cartridge the printer is producing blank pages. I should be able to provide useful information for locating a fix so you can get printing your essay!
If it is the cartridge causing the problem and you need to get that essay printed and out of the way. The printer works on a single cartridge mode. This means if you remove the problem cartridge then the printer can use one cartridge to print. The black cartridge will print grey scale and the tricolour will mix colors to make black.
Does this blank page only happen when printing from the computer?
The first thing you will want to check when getting a print quality issue is to perform a stand alone copy on the printer. To perform a stand alone copy please follow the link for Copy Text or Mixed Documents. this will let you know if the issue is related to the printer hardware or the computer software.
If the copy IS blank then please follow the document for Printer Prints a Blank Page or Does Not Print Black or Color Ink for the HP ENVY 4500 and Deskjet In...
If the document prints WITHOUT quality issues then you are likely looking at a software problem within the computer. If that is the case, for me to provide relevant troubleshooting steps I will need you to provide me with some info on the computer. What operating system your computer is running (ex. Windows or Mac). If you are running Windows please provide the bit version of Windows (ex.Windows 7 32-bit or Windows 7 64-bit.)
If you are running Mac but don't know the version, please follow the link for: Finding the OS X version and build information on your Mac
If you are running Windows but don't know the version, please follow the link for: Which Windows operating system am I running?
If you are unaware the bit-version on your windows operating system, follow the link for: Is the Windows Version on My Computer 32-bit or 64-bit?
Please post back with your results of troubleshooting and let me know how it goes!
thanks again for chatting on the HP Forum!

Unable to communicate with printer error with HP Envy 4500

Hi I am having trouble printing with my Envy 4500 printer. My computer system is Windows 8.1. I installed the driver per instruction from the website and use the usb cable to connect the printer. However when I tried to print a pdf document it says "Unable to communicate with printer" and I can't get the test page to print either. Please help! Thanks in advance!

Hi @Casey_Z , and welcome to the HP Forums!
I see you're having issues printing. I would like to help!
I'd recommend removing the ink cartridges, and performing a power reset. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I'd then suggest downloading and running the HP Print and Scan Doctor.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

HP ENVY 4501 e-All-in-One: Unable to Find Printer

I just recently got a HP ENVY 4501 e-All-in-One. The printer is connected wirelessly to my router but after I installed the software, it was unable to find the printer. I have tried it on 3 different computers. 2 with Windows 7 and the other with Windows Vista. How can I get the computers to find the printer? Also, can a Linux system also use the printer?
Thanks.

Hi blanchard10,
Welcome to the HP Forums.
I see that you are having some installation issues.
Just so you are aware, no Linux driver is available for this printer at this time.
I do have a few steps that we can try in the attempt to install the printer on to your Windows 7 and Vista computers.
First off, please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
Seeing that you are attempting to install the printer with a wireless connection, we do need to have the software and drivers installed on to each computer.
Here is the HP ENVY 4500 e-All-in-One Printer series Full Feature Software and Drivers.
Please make sure that you do NOT have any firewalls or anti virus protection running while doing the installation.
Save the download to the Desktop of the computers so that it creates its own icon. This will make it easy to find the download when it is completed on each computer. Double click the new icon and follow the installation instructions. The installation will give you connection options. Select wireless.
On the front panel of the printer, we will need to go through the Wireless Setup Wizard. To get to the Wizard we will need to be on the main display of the printer and touch the Wireless icon on the top of the printer window. Select Settings and then select the Wireless Setup Wizard and follow the instructions to connect to the network. You will need the IP address once the printer is connected to add to each computer when prompted to do so.
Please write me back if you are still having issues or if you have any other questions.

MFP M476dw poor color print quality with streaking

I bought this printer in January and only printed half a dozen or so color prints, but always has color streaks. I have printed may 200 B&W pages and they seem OK. I ran the calibration I found in the operator interface, but doesn't make any difference. See attached original image and scan of the color print. Yes the scan looks just like the color print. Color cartridges all show 80% full. B&W cartridge is 70%. scan of color print Original ImageWhat can I do to improve this? I really was expecting better color print quality.

I am experiencing horrible print quality with this printer. Colors are way off what they appear on the screen - reds appear yellow, browns appear blue / green. The printer has new HP ink cartridges, both basic and advanced inkjet cartridge cleaning processes have been run and the inkjet alignment process has been run. What can be done to correct this problem?

Hi ozzydog,
Welcome to the HP Support forums. I understand that you have recently gotten a new computer and you need to install your Envy 4501 driver onto your new computer.
I have included the Installing the Printer Software for a Wireless Network Connection document for you to follow. Please click on your operating system and follow the instructions. That will get the new printer installed onto your computer with the wireless connection.
