How to canon np 4050 scanner lamp continuously on

Basicly, a E224 is a scanning lamp error code. Here's a question for you??? Will the scanning lamp turn "ON" at all? If so, then the problem is with the scanner power cable. If the lamp will not turn "ON" you may have a blown lamp & or thermal fuse on the scanner unit. You can not clear the code until the problem is fixed. Good Luck

I believe a E02 deals with the scanner. Your copier is very old. It has been a long time scine I've worked on one. Have you checked that the exposure lamp has continuiy? If so, you may have a blown thermal fuse for the scanning lamp. Also, dose the scanning lamp turn "ON"? You may have a broken scanner lamp power cable. You should be able to order the parts on line.. Good Luck...

The door may be closed, but there is a inter lock switch that is not being closed. If you have all four paper tray, try to turn the copier off and disconnect the bottom two cassette's from the back of the copier and turn it back "ON" and see if the copier works. If it dose you have a problem with the bottom two tray's. You have a very old copier, can you do with out them? If not the switches are toward the front & it may just be knocked out of place... Good Luck...

The toner is not adding correctly into the developing assembly. 1) If toner hopper is overfilled, the toner motor worm gear splits as a result of the hopper becoming packed tight. 2) Sometimes the worm gear splits under normal use.

I am not 100 percent sure what is happening to your machine after it comes to ready, but I will offer some thoghts.
If it comes to ready and then goes back to a low heat situation. It very well could be the board if it doesnt maintain heat.
Now that being said, once a coiper comes to ready and reaches full heat, it will switch over to pulsating the heat roller, not staying on fully all the time. That is how fusers are designed. Full on until they reach operating temperature, then pulsating to maintain the rollers heat level.
If you are having a problem with the image not fusing to the paper, you may have an issue with the pressure roller not making good contact with the heat roller.
There may be a software setting that needs adjusted to increase the fuser operating temperature.
The flickering heat rod, once the machine reaches ready, seems appropriate.
If you want more of an idea, can you be more specific as to whether the machine is faulting out with an under heating situation, or is the image not fusing to the paper properly?
