How to replace exposure lamp canon ir8500

remove the covers to and the top glass to gain access to the lamp .
Ensure the A/c power supply is removed from the socket as at times the fuse / tripper may still be live . remove one end of the copper conector , gently slide the fused lamp out. Check the voltage with out replacing lamp, if the volatage reading is near about the lamp rating , replace lamp , if voltage is slightly higher ( 10 % ) it is ok as in many lamp circuits the supply is not a sine wave , but is a saw tooth wave.

I have copier CANON PC981, when i copying theres an error coming out to displays says E2 followed by 20. and turns off automatically. how to fix this problem, thanks

Dear marlauris,

According to Canon this error is mainly due to faulty x-lamp, power supply, or exposure sensor.
As a technician I fixed this type of error by replacing exposure sensor in several similar cases. So replace exposure sensor it will solve your problem.If you have any difficulties to resolve this issue let me know.

Hi i have a canon np2020 copier has code E221. the exposure lamp is not coming on . is there a way to check is the lamp is good with out replacing it .

There are a few possible problems? One is that the scanning lamp is blown or the thermal fuse for the lamp is blown. The question is will the scanning lamp turn "ON" and move and then codes out. If that is the case and most likely the power cable for the scanner lamp is cracked and it is shorting out to the frame of the copier. If you have a meter to measure resistance. You need to turn the copier off & unplug it & take the copy board glass off & put the meter on the ends of the lamp, to read it's resistance. If you have No resistance then the lamp is blown. You will need to replace it. Keep in mind you are working on a copier at least 15 - 20 years old, odds are the power cable is cracked. Good Luck.. If that is so, it is not a easy part to replace or find
