Hi, you just reinstall the scanner software and then try.
OR
If your scanner in the warranty then replace it because this is the major problem in the flatbed scanner.

Do I need a new scanner bulb?


It sounds very much as if the scanner is faulty/failed. The warming-up phase is to ensure that the scanner lamps output is steady, making for consistent scans. Usually this is just a simple timing circuit.
Having once tried to fix a broken flatbed scanner myself, I found that obtaining the correct replacement lamp for it was impossible - I think inkjet printers and scanners are considered "consumable". You may be better off buying a new printer. Alternatively, if it keeps producing good prints, consider buying a separate scanner. HTH

Where is the power button on a canoscan lide 70 scanner?


There is no power button on mine. It gets its power from the high speed usb so it is always ready. Every time I boot up my mac I hear the scanner go thru a warm up scan. I have downloaded the twain plugin for photoshop and access it that way. The lamp will go on when you preview scan something.

Hello, The scanner & photocopier were not working and the screen was just stuck on the "scanner bulb warming up". Then, after days of trouble shooting, it finally began making a noise,...


From what you described it sounds like you need to get the "scanner assembly" replaced.
The bulb is probably bad and won't come on to full power.
Not knowing what kind of printer you have, probably won't change the fix. If you can look at the event log you may be able to see an error code which could make it a definite scanner assembly replacement.
If you want to throw money at this unknown printer, get a tech to look at it and give you an estimate.

HP Laserjet 3330 Multifunction monochrome printer,copier,scan and fax. This machine will warm up, and after it reads "scanner lamp warming", the scanner lite lights up, the carriage moves back and forth,...


Hello,

This type of problem is usually caused by dirty mirrors in the scanner. After a few years of use the mirrors and lenses in the unit will get a fine coating of dust particles on them. The dust interferes with the scanner initializing the optics. When this happens the unit displays the Scanner warming up message on the screen and keeps trying to move the scanner assembly to get a good reading from the pickup. To solve the problem you will need to disassemble the scanner portion and clean all of the mirrors with window cleaner and a soft cloth or q-tip. To get dis-assembly guides just do a google search for the 'scanner warming up' error.

I hope this helps, If so please rate our solution.

Canon Scanner 5000F fails when adjusting lamp before scan.


Have the same problem. Suspect a lamp problem but cannot find any info/help to check lamp or to replace it

Adjusting the lamp


Hi,  This is normal for the 4200F and it's just the time taken to warm the scanning lamp up. Once it's warmed up it shouldn't need to go through the process again for any additional scans, unless it's had long enough to cool down again of course.
I've noticed from another answer to an earlier question that if it's a big problem you can change the following keys in your registry:

HKEY_CURRENT_USER\Software\Canon\ScanGear\8.6\Devices\CNQ4200
 Energy save changed to 1
 Lamp Off Time changed to 0


Looks like this would prevent your lamp switching off at all unless you unplugged your scanner which would undoubtedtly shorten your bulb life. It may be a better idea to play about with the 'lamp off' key number until it just stays on long enough to not cause you problem.

Cheers, Derek

Scanning problem


Possibly there is a key that locks the engine that moves the scanner lamp, and that key may be locking the engine, and when the scanner try to move the lamp, the locked engine overloads the circuit, and turn off the device. Search for that key, and unlock this, (if it´s really locked).

Black output


This type of issue could be related to different sources. First step I would do is check to see if the lamp is coming on within the scanner, possible bad lamp. One other possibility would be the CCD failure, it may not be moving across to capature your film. Also, when attempting to scan does the scanner sound normal or abnormal. If abnornal sound is occurring then CCD could jammed/stuck hardware failure. Last step would be uninstalling/reinstalling your scanner software, check for updated drivers from the manufacture of your scanner. At this point if none of these suggestions helped then test scanner on a different computer system.

?Scanner failure? error message


Usually this type of error message pops up when the scanner lamp isn?t warming up properly. This is what you should do: 1. Check if the lamp is on. 2. Unplug the scanner?s power supply and plug it back in. Try connecting it diretly to the wall. 3. If that doesn?t work: a. Unplug the unit?s power supply. b. Press ?cancel? and left arrow while reconnecting the unit. c. Release the buttons when the printer starts up. 4. Try scanning again. 5. If it doesn?t work, have it serviced.
