When the scanner scans the first image it will bring in via a set of solenoids a background white Reference metal flap for both rear and front cameras.
The above error comes about when the solenoids are sticking or they have magnetised themselves.
1.Clean the Solenoids.
if scanner still errors .
2. Replace solenoids.

SOURCE: Background changeover unit failure

Hi Vivek,
Thank you for contacting Fixya.
When a background switching malfunction occurs, "E" and "F" will display alternately on the function number display panel of the scanner.
Background changeover unit failure error is detected in initial checking at power on. Probable causes:
- Insulation material damage of BW motor cable or the damage of the wire in the motor. - Defective lamp or CCD or CCD cables. - CCD Connector disconnected. - Defective Control PCA.
Solution:
Wipe the top and bottom glasses located inside the ADF with the Cleaner F1 (or isopropyl alcohol) and check if the problem persists.
1. Does the same symptom occur after turning OFF and ON the scanner? Press power button of the scanner for more than 2 seconds to turn it OFF, and after more than 2 seconds elapse, press the power button to turn the scanner ON. 2. Check if the cables between the Control PCA and the BW motor damaged? Are the connectors connected correctly? Check & confirm the position of the BW motor and check the cables. 3. Check Is the CCD cable F or B damaged? Or are the connectors connected correctly? 4. Check if the OPT Unit is installed correctly? 5. Check if the white reference works properly? If not, then replace the BW Motor. 6. If the above do not resolve your issue, then you may have to replace the Control PCA or Optical unit to see if the error is resolved.
Hope the above information is helpful.Please revert if you have any doubt.

Regards,

TechSatya

My MX922 printer worked well this morning. All cartridges have ink but ALL lights under the cartridges are on and print comes out blank. There are no error codes or anything abnormal displayed


This problem is mainly happens to all inkjet printers. If your printer print blank pages then please at least once go to official site of Canon and check whether there is any printer/scanner drivers update is available or not. If yes then download it. Also check your ink cartridges. Because if there is no print on paper that means your ink might be dry.Sometimes it clog the print head. If your ink cartridges get dry change it. Or you should clean your printer's print nozzle by using printer's control panel. I hope all these suggestions helps you. If doesn't then watch Canon MX922 Manual English

How does the bulb look? Is it bright or kind of dim. The bulb warming error is designed to halt use of the machine until the scanner bulb reaches the correct output level. As these are basically a flourescent tube, they will dim over time and at a certain point they will not generate enough light to enable proper scanning. If the bulb is dim, it will require replacement.

Why does canon MP258 printer with scanner can't scan japanese yen paper bill amount 10,000. I tried it over 10 times but it stops,. And when i tried US paper bill, it works well. I need some explanation...


When you scan with any scanner it utilised the software with "Optical Character Recognition functions, usually abbreviated to OCR -> OCR is a field of research in pattern recognition, artificial intelligence and computer vision." to scan and record the scanned object, sometimes it does not or cannot recognise certain symbols or characters because of man made software & hardware have its limitations too.

Hope it helps.
