Question about Scanners
Canon ir1023 won't scan to email, gives a result NG 0801 or 0802. It is on a network, can print to it, can browse to it with remote interface. Can't find what does the 0801 or 0802 means?
Check the lock switch and make sure it is unlocked. I think the lock switch is on the bottom...or it may be under the lid near one of the hinges. Flip it back and forth and leave it in the unlocked position.
If this doesn't work, then it will most likely need service. Contact Canon Tech Support.

I had the exact same problem with another scanner (LiDE 80) after years of use. It stopped being able to calibrate itself so I couldn't use it on computers where it had never been installed on before (since on freshly installed computers, the driver requires calibration to be carried out at least once).
Hopefully my solution will work on the 500F, albeit with some modifications you'll have to figure out yourself. :P
What I did was open it up, the two strips of plastic to the left and right of the platen can be used to remove the glass surface:
1. release the oval catch at the front of each strip by prying them upwards.
2. slide the glass towards the front of the scanner a bit till a gap appears between the end of each strip and the back of the scanner.
3. pry a bit of the back of both strips upwards and keep them away from the glass so they won't stopped by the back of the scanner.
4. slide the glass all the way to the back, you should be able to remove the glass since the two plastic strips aren't blocked anymore.
The reason the scanner fails to calibrate is because it tries looking for the black/white strip hidden between the plastic case and glass panel at the front but fails. There are three possible reasons:
1. Dirty glass panel/damaged black/white strip
2. Covered/dirty CIS module
3. Loose drive belt
Mine was a combination of the first three. A little washing and thorough drying of the glass panel and black/white strip and careful wiping of the imaging element and led strips (the black bar is the imaging element and the white bar is the led strips) fixed the problem.
I didn't have a loose drive belt, so I didn't look into fixing that, but I see a spring loaded catch holding the drive belt tension; if you have a loose belt, it may be worth it looking into that.
A tip of advice: If somehow, after reassembling your scanner after tinkering with it it still refuses to calibrate, you can do a dirty workaround by doing the calibration with the scanner disassembled and placing the black/white strip manually above the CIS module at the front, making sure to hold it steady. Your images will look a bit muted, but at least it works! (I did this step before I reassembled the scanner just in case it wasn't fixed, but thankfully its working now!)
