Photosmart C4780 Mac OS 10.9 scan clear on preview, but saves black with white horizontal stripes

I'm having difficulty figuring out why my scanner all of the suddens saves all scanned documents (.pdf, .jpeg, .png) as a black document with white horizontal stripes. The preview scan from the utility looks fine.
I recently updated my Mac to OS 10.9.2
I have uninstalled all HP utilities and drivers and reinstalled them with all updates.
Printing works fine, as does copying.
I scan a lot of forms, so this is disconcerting.
Thanks for any help.
PS: I see that this is an issue that seems to have been solved for others, but my printer/scanner is not one of the ones listed. Is there another driver to try?
More info: Here is the error code log:
E [04/May/2014:21:42:15 -0500] Unknown directive BrowseAllow on line 23 of /private/etc/cups/cupsd.conf.

Hi,
This is a known compatibility issue with the HP Scan application, which is not supported on 10.9.
You may scan using Apple's Image Capture or Preview as listed as a workaround in the following document, a Full Feature Software for your printer is not available for the operating system:

Hp photosmart C4780 error message when saving scan to MAC OS X 10.9.5

Hello sun4u,
I apologize for the delay in my response time.
I have done some more research in to the issue at hand and I have found some additional steps that we can try.
I suggest that we go ahead and take the steps to Reset the Printing System.
Once the Printing system has been reset, let's go a head and download the HP Printer Drivers v3.0 for OS X.
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Thanks again for your time.

Scanned documents from preview yield blank/black pdf

I have just upgraded laptops and operating systems moving from Snow Leopard to Lion. I am attempting to scan text documents using Preview in Lion as I had done before using Snow Leopard. I am using the same printer/copier/scanner, HP Photosmart C5280, but am encountering different results. When I scanned documents from my previous MacBook using Snow Leopard, I achieved the desired pdf document results. However, when I scan the same document using my new MacBook Air and OS X Lion, the document saves as a blank/black pdf. Does anyone have any idea why this is occurring?
Any help is greatly appreciated.

Rysz,
Thank you very much for your prompt reply.
Unfortunately, I ran Software Update and also referenced the HP site to determine the driver for Lion. My driver is up-to-date and no software updates are available.
I am going to keep researching.
Thanks again for your help.

Are there any updates so i can use my HP Photosmart C4780 All in One Printer wirelessly?

just wondering..are there any updates for the iMac with OS X (10.8.2) so I can use my HP Photosmart C4780 All in One (Print,Scan,Copy)?

Hi,
An HP Full Feature Software is not available for Mountain Lion, therefore the Wireless configuration is tricky and cannot be done through the software.
To connect the printer to your wireless network you will need to create a temporary wireless ad hoc connection, then the wireless connection to your router can be configured via the EWS page:
Step one: Restore the printer's network default settings
Touch the ATM button ( ) next to Wireless / Scan .
Touch the ATM button ( ) next to Wireless Menu .
Touch the ATM button ( ) next to Wireless Settings .
Use the up and down ATM buttons ( ) to select Restore Network Defaults , and then press OK .
Touch the ATM button ( ) next to Yes to confirm your selection.
Step two: Networkly connect the Mac to the printer by creating a temporary ad-hoc connection
From the Mac, click the Wi-Fi icon.
Click Join other network.
Click Show Networks.
Select the printer's SSID, it should be listed as HPSETUP or should contain HP or C4700 within its name.
Click Connect
Allow two-three minutes to fully establish the network connection.
Step three: Connect the printer to your router via the EWS page
Open Safari.
Click the Bookmarks icon ()
Click Bonjour.
Double click the printer name, the EWS page appears.
Open the Networking tab.
From the left pane select Wireless.
Click the Start Wizard button and follow the steps to connect the printer to your router.
Step four: Reconnect the Mac to your router
From the Mac, click the Wi-Fi icon.
Click Join other network.
Click Show Networks.
Select your router SSID.
Click Connect
Allow two-three minutes to fully establish the network connection.
Now the printer should be connected to your network.
Open Print & Scan, click the Plus sign and add the printer listed as Bonjour.
btw John Galt - I this it should be spelled as OS X, please correct me if i'm wrong.. ;-)
Hope that helps,
Shlomi

My photosmart C7250 all-in-one used to allow me to print black and white only, now it won't

My photosmart c7250 all-in-one used to allow me to print in black and white only if I changed properties to print in grayscale, black and white only. Now it says it won't print until I replace one of the empty color cartridges. I do no understand why the color cartridges are running out when I only use my black cartridge.

I still don't understand the difference between what I used to be allowed that I'm not allowed now. I was able to bypass the empty color cartridges by changing my print property to "grayscale" and "black only". Now I'm not allowed to bypass???

No longer able to use the scan function on Photosmart c4780

Previously when I opened my HP Photosmart C4780 Printer Scanner I would get a dialogue box which allowed me to choose whether to print or scan. This dialogue box no longer starts and I no longer get the option to select scan and can only choose to print. I have been around the circuit of Print and Scan and Doctor and have downloaded and reinstalled the appropriate software several times all to no avail. I can no longer find the software CD that came with the device. What do I have to do to be able to access the dialogue box which gave the opportunity to choose scan and specify the actions required?
Furthermore using Windows Fax and Scan will not work either, I simply get the message “Could not complete scan”.
The scanner does work as I can use the copy function perfectly well.

Hi @Jumbob

WiFi connection problem from HP Photosmart C4780 to MacBook Pro

I have an HP Photosmart C4780 that will not connection to my MacBook Pro. I am operating on the Mac OS X 10.6.8. It was working just fine when I was using my Apple Airport to project the WiFi in my house, but I recently bought a Apple Time Machine to back up my system and have a main networok and guest network for the house. When I switched to the new device, I am now unable to get my printer to reconnect via WiFi. I have downloaded all of the recommended software from the HP site.
When I click on set up wireless connect, it starts the first step to find the device and then I wait and wait. It just sits and spins and never finds the device. Yes I have it plugged in and turned on. I did not have any problems with this prior to switch the router for the WiFi so I am guessing it has to do with that, but I am lost on what to do. Please Help

Welcome to the HP Forums FlyGirl_1350,
I see by your post that you now have the Apple Time Machine and aren't able to setup the printer again on the network.
I can help you with this issue.
Follow these steps to restore your product's network default settings. This will clear out the old router encryption.
Touch the ATM button () next to Wireless / Scan.
Touch the ATM button () next to Wireless Menu.
Touch the ATM button () next to Wireless Settings.
Use the up and down ATM buttons () to select Restore Network Defaults, and then press OK.
Touch the ATM button () next to Yes to confirm your selection.
Make sure the computer is connected to the Main Network Name and not the Guest Network name.
Vice Versa. Sometimes the printer won't pick up the Guest Network to configure the wireless.
Run the setup again.
This document provides steps for setting up the printer on the network also.
Installing the Printer Software for a Wireless Network Connection (Using an Access Point).
If you are still having issues then power cycle all the devices in this order, power cycle the router, wait till it is back up again, turn the computer off and on again, turn the printer off and disconnect the power cable for 30 seconds, then reconnect it again.
If there is anything else that I can help you with just let me know.
Have a nice day!

Cannot wirelessly connect printer- HP Photosmart C4780

Hello everyone! I have scoured the internet and these forum pages for a solution, but could not find any. Anyways, I have a HP Photosmart C4780 and am unable to wirelessly print. My printer will not connect to the internet nor does it show a local network for my computer to print to. When I try to print off a Network Configuration Page, it will not let me. I click the "Ok" on the printer when that option is highlighted, however it takes my back to the wireless menu. I have an AT&T router that I believe does not have a WPS. I also have the latest software downloaded on my 2015 macbook pro. To make things more complicated, I do not have the set up wizard disk, and when I try to download the corresponding software to get the "HP Folder" on my computer, it goes through the installation process but does not show the folder once it is finished. Please help me!

Hi , I see you have been looking for a way to reconnect your c4780 wirelessly with your Mac 10.10, I have actually helped with this before. Normally, it's an easy 3 step process to reconnect the printer but because you have Mac OS X 10.10 Yosemite which uses the driver from Apple, there is no software package from HP to configure the wireless.
So here's how you can do this; Step 1: Make sure your computer is connected to the correct network. Confirm your settings for your home network; HP Printers - Find Your Wireless WEP, WPA, WPA2 Password (Mac) Step 2: Restore the Network Defaults on the printer so it's not holding onto any old information.* To do this you should be able to touch on Setup [Scan] front of the printer then choose Network and then Restore Network Defaults Note: If your wireless radio is not working correctly, let me know and I will send you a different reset in a private message. Step 3: This would normally be to use a USB cable and your printer software to configure the printer back onto the network but you will need to follow the directions from this similar post, copied here for you below; After you Restore Network Defaults, the radio will turn off (the blue LED will go out.) You may need to press the wireless button again to Enable Wireless (light should be flashing.) Put the computer on the printers network (temporary)1. Click on the Airport symbol on the top left side of the Mac screen
2. Choose the network that look relative to the printer (might say HP setup or some variation of your printer name) - it may take a few minutes for it to appear Print the wireless network test - wait a few minutes to ensure the and computer have established an adhoc connection otherwise the report will not have an IP addressPress the Scan button (it also the Wireless menu button)Select Wireless SettingsNavigate to Wireless Test and select.The Wireless Network Test prints, look for and note the IP address. Open an Internet browser (Safari) and enter the IP address into the URL (address bar). Click on the network tab, on the left click on wireless or 802.11. At this point we are looking fore "start wizard" should be on the right hand side. Now just follow the on-screen prompts to configure your printer to the network. Once we have successful configured the printer for your network you can put your computer back on your own network. Now you can add the printer to the System Preferences and print. (If you are unsure of how to do this see; Add or remove a printer. Please let me know if these steps resolved your issue, or if there is anything else I can do to help. I look forward to hearing from you! Thanks,

Photosmart C4780 install fails at "system cannot find specified file"

My problem started simply with the printer, an HP Photosmart C4780 which has always had a wireless connection and would not print. At first, the network connection checked out fine from the printer control panel. I ran a Microsoft printer troubleshooter, which found a block in the print queue, and cleared it. The first test page would not print, but the "inner test page" did print. I didn't understand whatever that meant, so I looked for help from the HP site.
I ran the HP Print and Scan Doctor, and it suggested I reinstall the driver. I downloaded and saved the current one from HP (PS_AIO_06_C4700_USW_Full_Win_enu_140_175.exe) and then uninstalled the existing driver. When I attempted to install the new one, a window popped up saying, "The system cannot find the specified file," with only one box to click which said simply "OK". The installation went through to "review installation options", after which came “checking updates, downloading updates, installing updates” and then it was while “checking system” that the “cannot find the file” window popped up, and when I clicked “OK”, the installation window as well as the error message box, just disappeared. What I assume was the file path was in the frame of the window, but the whole thing didn't fit so it didn't show the end. What I could read was “C:\Users\ … \Local\Temp\7zS588E\Setup\.\Setup\hpzpnp40 …
I found one topic on the same problem for the same model printer in the forum, which offered this fix:
You will need to first complete a level 3 uninstall of the software. I have included the steps below for this.
1. Press the Windows key, and the letter R
2. Type %temp%, and click OK
3. Open the 7z folder (most recent one if there are multiples)
4. Open the util folder
5. Open the ccc folder
6. Double click on the Uninstall_L3
Once the Uninstall_L3 has completed, please delete all items listed in the temp folder. Note, you will not be able to to delete all items, please skip the ones that you cannot. Next please empty the trash, and perform a clean boot. I have included the document 'How to perform a clean boot in Windows'. If your computer does not request it, please restart your computer.
Once your computer is back up, you will need to reinstall the printers software. You can either do this by using the Installation CD, or downloading the software.
I did what was suggested, until it got to the point where it said it did not recommend removing any further items if I intended on using the HP Officejet printer (yes I have a second HP printer attached to the network) anytime in the future. Not really understanding how this all works, I decided to stop what I was doing, so unfortunately it did not solve my problem.
Do I need to uninstall both HP printers before I can reinstall one? And if I do that, is there any reason I would not be able to reinstall both printers? Sounds like I'm asking for trouble. Bottom line... I still cannot install the driver.
I have tried to install both the full and basic versions of the driver and always get the same result.
I have an HP Pavilion dv6-3100t notebook, running Windows 7 Home Premium, version 6.1.7601 service pack 1, 64 bit. I haven't installed any new hardware or software. This printer has always had a wireless connection. The router I use is a Netgear 54 Mbps WGR614 v6 (supplied by my cable company), and the network includes not only my notebook and the Photosmart printer, but also an ASUS desktop, another HP printer, an Officejet 6300 series (used only for printing graphics and photos with a wired connection to the router), and a Vizio smart-TV. I use Norton 360 Premier Edition and disabled the anti-virus auto-protect when I downloaded and attempted to install the driver.
Please help! And thanks in advance for your time and attention.
This question was solved.

Scanner not working HP Photosmart C4780

I have OS X 10.9.5 and a HP Photosmart C4780 printer. I'm trying to scan something to a pdf and I'm getting a black image. When I scan an 8.5 x 11 size document as an image it only scans 1/4 of the document. Please let me know if there is a driver that will fix this. Thanks.
