Question about Samsung SCX 4521F All-In-One Laser Printer

Scanner not working

I have installed the ScanThru driver on my computer (IMac with OS X, 10.4.8) but I am unable to scan directly. There is no icon on the desktop, dock, or applications. I am able to import the scanned image with Microsoft Power Point (Office 2004 for Mac) only. How can i scan an image and save it to the hard drive without opening another application?

Re: Scanner not working

No solution, but the same problem with my iMac. Followed all installation instructions but nothing appears as the manual instructed. Called Samsung's HELP humber and was told, very **** , that they cannot provide support for a Mac. Really? Why does Samsung claim the SCX-4521 is "totally compatible" with Mac? Either change their claim or get somebody on the desk who has a solution!

How do I scan a document?

Do you have the full software installed or just the basic driver from Canon? What OS are you using? has the software and drivers. If you installed the OS driver, you should uninstall that, disconnect the data cable and then install the driver from Canon. The generic OS driver usually only runs the printer.

Place the document face down on the scanner glass or face up if you have an ADF. Check that the all-in-one and the computer have good bi-directional communication. (Direct USB connection (if you are using that), replace cables if the printer works but not the scanner and the Canon software is installed.)

If you are using the Canon software, you need to set up the destinations for the buttons and have the monitoring software running. Thus start scanning from the computer at first. Launch MP Navigator and then click on the type of document you want to scan. Find the resolution and contrast that works for you. Use these in setting the button defaults (see the manual from Canon). Then click Scan.

Alternately, with Windows XP, Vista and Win7, you can scan with software that came with the OS. Paint is available on all of these OS versions (File > Import from camera scanner > from scanner). Vista includes PhotoGallery which works like Paint (this can be downloaded for XP and Win7). Vista and Win7 also can scan with Windows Fax and Scan (New Scan).

When you have the MP Navigator properly set up, you will be able to launch a scan from the printer. Press the Scan button and the software will launch.

I hope this helps.

Printer says no scan options but its an all one

Hi! My name is Mace and I'm here to help.

Scan options will not be available if you failed to install the scanner driver in your computer.

How do you know if the driver for scanner is not installed? Connect your printer directly to your computer. Meaning, it is locally connected and not on network. Assuming you are using a Windows OS, on Control Panel double click Scanners & Cameras icon. See if your unit is listed. If your unit was not there, then it means that the driver was not installed.

I do suggest you run again the cd installer that comes with your printer all in one to install the driver for scanner.

I hope this answer will help you. Post back if you still have some questions.
Thank you for using Fixya.

I want to scan a picture onto my laptop i connected the cables and evrything. ir prints fine. but it dosent want to scan and my printer is a dell 924

Did you install the full software (if available for your OS) before connecting the cables? Were you trying to launch the scan from the computer or the scanner? The scanner buttons will not work unless the full software is installed and the monitor program is running.

If you installed the generic OS driver, uninstall it and then unplug the data cable. Then download and install the software from . Select your OS and click Next then click on Drivers. Start scans from the computer first. (HP Solution Center has destination buttons that need to be set before the buttons on the scanner can work. Once you scan from the computer, you will have a better idea of the settings you should use as defaults for the buttons.)

Try connecting the printer directly to the computer, if you use a USB hub or print server. Also try a new USB cable. The scanner requires bi-directional communication and thus can fail even if the printer works. Your cable should be 6' or less in length.

WinXP, Vista and Win7 have options for scanning without the HP software. However, they do not work with the scanner buttons. Launch Paint (Start > All Programs > Accessories > Paint) and select File > Import from Camera or Scanner > From Scanner in any of the listed OS versions. Vista and Win7 also include Windows Fax and Scan (New Scan). Vista has included Photo Gallery that also can acquire Scans (this is available for Win7 as part of the Windows Live package download).

I hope this helps.

How do i scan documents onto my comp

It depends a bit on the software you have installed (OS, etc). If you installed the full-featured software before connecting the all-in-one to your computer, you can scan immediately from the computer. For Windows, open the HP Solution Center (by double-clicking on the icon or Start > All Programs > HP folder > HP Solution Center). Put your document to be scanned face down on the scanner glass and close the lid (ADF pages go face up, top edge first). Click the tab in the Solution Center for your HP product (if you have more than one) and click Scan Picture or Scan Document as appropriate. Set the scanner settings in the pop-up window if needed. Click Scan to start the scan. To use the buttons on the scanner, you need to set the destinations for the buttons in the HP Solution Center (Scan to destination for example) and have the HP monitor running on your computer (this listens to the buttons).

Scanners work with bi-directional communication so USB hubs, print servers or bad cables can result in the printer functions working but not the scanner.

If you install the generic OS driver (by connecting the all in one to the computer before installing the software), the printer will work but the scanner will functions will be limited (the scanner buttons will not work but other functions will depend on the OS). Windows XP can acquire scans in Paint (File > From Camera or Scanner). Windows Vista and Win7 add Windows Fax and Scan which will also acquire scans (not in all versions of Vista). Vista also can acquire scans with Windows Photo Gallery.

The printer works similarly with the Mac OS but hte names may be different.

I hope this helps.

Unable to scan after install windows vista home premium w sp 1

You don't have bi-directional communication between the all-in-one and the computer. (If you launch the scan command from the computer, Windows Photo Gallery, Paint or a third-party program). Solve this with a new USB cable. If you are using a print server or USB hub, try a direct connection.

If you can't launch the scanner from the buttons on the all-in-one, that is due to the fact that you are using the driver in the Vista OS. HP does not offer a full-feature software for this printer for Vista.

In Paint, to acquire a scan: File > Import from Camera or Scanner, Choose Scanner then New scan.

I hope this helps.

You would need to download the software for your printer again and then install it on your computer. You can download it from here. Once it is installed, look for the scanner icon or HP Director which would have scanner icon.

Download the first link from the list.

Can't scan from HP psc 2400 to iMac computer

You need to set up the software on the iMac. The reason it gives you that error message is because it can't communicate with the computer and imaging software as the computer doesn't see the scanner and can't communicate with the printer's control interface. The iMac may see the printer and be able to print without any additional software because the driver package for the printer portion may already be installed with the OS X HP printer driver support. You didn't mention whether or not you could print from OS X. I am assuming you can. Faxing and copying from the unit doesn't use the computer at all and doesn't need to communicate with it. Scanning and printing do. If you can't print either then none of the driver or support software is installed and you have to set it up. You can get the instructions for setting the printer up in OS X 10.5 from HP. Just click here and it will take you to the page with the instructions.

Best wishes and cheers
