Unlocking scanner on an all in one printer

My desktop computer crashed sometime ago. Just before it crashed the printer wasn't working properly anyway. I put the printer in storage and just got it out to use it with my laptop. I'm having problems with two different things. When installing the software I get a msg that the spooler service isn't working. "Check yes if you would like to start it and continue". When I click yes nothing else happens. I try using Run As but still nothing. Also when I power it on it says to unlock the scanner and then power it on. Even though I have had it for a while, most of the time it's been in storage. It is basically a brand new printer. Can you tell me if you think the printer is unfixable. Thank

Re: unlocking scanner on an all in one printer

Dawnmj: I?m at Dell Headquarters in Austin, Texas and I just came across this post. I'm sorry to hear you're having trouble. The first thing that I would try to fix the spooler issue is see if there are any other printer drivers or leftover pieces of printer software from ones that may have been installed previously. If you come across any I would delete them completely and then reinstall the proper printer driver. As for the other problem, when and where are you seeing the message about the scanner.

I can not scan using my HP color laserjet 2840

Hello, wmpinc1

Sometimes what happens is that the software installed on your computer, relating to the printer will become sort of confused. Re-install the software after a quick un-install of the same software. You can get the software from either a disc or from the Web Site of the scanners manufacturer.

Sometimes updating the USB Drivers will be needed. Do that by visiting the maker of your computer and search for Drivers and Updates on their Web Site, look for 2.0 USB drivers class, download that package to your desktop. The driver might be in the form of a Zip FIle. In that case, unzip the files using standard WinZip program or use software provided by computer, to a folder called cab. The driver program might show preference were it wants to unzip to. If so, let it do its thing. Then afterwards find the folder (cab or other folder) run USB driver by clicking install exe file. Note that all periperials need to be unconnected from all USB ports ( the port the laser printer connects to the computer at ) before updating USB drivers. So check cables for solid reconnection after installing drivers.
Its important to recognize the version of the operating system you own. You'll find that information by clicking on Start Menu > Settings > Control Panel > System.

After doing this update, an reconnecting the power and USB cables. Check the operation of the scanner table itself.

Verify that there is nothing wrong with the light bulb belonging to the scanner. To do this have the cover up of the scanner table (if there is a cover) and press scan button, the program should initialized on your desktop, the the light should turn on (look for a light turnning on) and after a few seconds (or more) somethiing should start moving indicating the scanner is working properly. If you think the scanner is defective contact HP.

Good luck, jasahasch

My Visioneer 8650 flatbed scanner with auto document feed gives a message when I try to scan a document, telling me to move the switch on the bottom from the "locked" to "unlocked" position. The lock is...

Actually a very common problem. Try the following:
1. Power down then re-power up the scanner.
2. Try slightly moving scanner. Sometimes a small change works to fix.
3. Change one of your scan setting to flatbed scan (not adf). Do a test scan under this setting. This will usually kick start scanner unit to unlock.
4. Last resort, by does also work...give it a medium slap on the side, sometimes unjams the scanner light.
5. Super last resort, power down over night, it almost always works the next day. (could be that lock up is heat related to scan lamp, dont know but just a guess).
Excellent scanner, so worth the effort to try these fixes.

Need te driver for my P4350

"Yes" I can.
Go to the following link and download your software. I think you'll have to select your country, etc, then just type your printer model into the "Product selector":

Richo 1515 MF Error message: 12320 couldn't find the scanner.

This is a message on your PC...not the machine itself obviously? Was this scanner ever configured to work on your PC? If not, then follow this link to my comments to someone else about this machine:

Scanner won't work on Dell 924

Same thing happened to me, only different model.

First, make sure you have the right drivers (and by that I mean 32-bit or 64-bit).

Go to control panel and remove your previous installation; reboot; reload the drivers with your All-In-One UNPLUGGED until they tell you to plug it in.

That was the trick that worked for me. Good Luck.

My printer and scanner do not work. Both are canon

Please consider and remember when the printer or the scanner did work properly. Also give a moment to note what has happened recently, before the onset of the current problem. The record will help to continue to narrow down the likely cause or causes and most quickly arrive at the solution for this problem, for these two problems.
Perhaps you have a hardware problem with a hub that connects the printer device and the scanner device to your PC, but lets look at and try some very basic things to try to fix the problem before even pursuing any hardware repair or hardware replacement.
First start with basics. If you have recently added camera software and a USB camera or a Firewire IEEE 1394 cabled camera, remove the camera for this trouble shooting activity, to see and try to get the printer to work again. Leave the scanner disconnected too.
Start the computer. Check to see if the device is found and is identified correctly. For the printer, see if it appears in your list of printers. On a PC, see in the Start Menu, the item Printers, or Printers and Faxes. Move your mouse pointer over it and see what message may appear. Right click on the printer and select properties. See the condition of the printer. After you have right mouse clicked with your ring finger, click on properties. Let's start by getting your printer to work. Maybe locate your Canon software driver installation CD, or go to for the driver and download it, choosing to Save it to your desktop or into C:Temp or C:Downloaded Printer Driver - Canon (if you do not know how to select the destination folder, do not select Save, simply select Install. The advantage of save before doing install is to have the driver available to make a driver CD for any other trouble shooting or computer reload activity you may want to or may need to do, to get the printer working sometime again in the future.) The ways to fix the printer problem include first, simply disconnecting the printer, then reconnecting it to the PC, and checking to be sure the printer is powered on, is online, not offline, and is actually well connected properly to the computer. The next thing to try will either be to delete the printer from the Printers in the computer and then to readd the printer. The driver will be needed so it is very helpful to have the driver installation CD or the downloaded driver - it is necessary in many situations, but some printers have drivers included in the Windows 2000 or Windows XP Home or Windows XP Professional or Microsoft Vista operating system. Best to have the newest correct driver from the manufacturer website before deleting your printer, and then proceed to delete and readd the printer. Your printer may have a flashing indicator light, a blinking that you can match up to a solution in the printer user manual or printer operator manual or the printer manufacturer's printer troubleshooting and support website. The small display screen may indicate the printer is offline because of a paper jam or because the ink supply has run out. Resolve any problem with the printer. See if this fixes the printer problem. Then proceed to add the scanner, or disconnect and reconnect the scanner, or download the driver or locate the manufacturer supplied scanner software installation CD and drivers that are needed for your computer to run the scanner. Sometimes you will find that you can set up the printer and the scanner to work directly to the printer, and then after working properly, disconnect the cable and connect the printer USB cable to the USB hub. Do the same steps to get your scanner working with it connected directly to the computer, then try to connect it to the USB hub and shut down the computer and restart the computer, and see if all is resolved by these steps.

Scanner not working

Samsung can be cheeky with support i have found and not as helpful with tech help. Instead of going off in tiny circles with unlocking etc, i would go for the quick fix and suggest your scanner may not have installed properly when you installed it. As you have installed the drivers again with no luck i would even suggest goint to samsung web site and downloading new updated drivers for your printer to eliminate corrupt drivers. Does you pc register the scanner being there? Go to control panel, hardware/ printers, find your printer and check all the drivers and whether scanner is actually present on the pc here.
