SIR,i AM RUNNING IR 400 FOR 2 YEARS THIS TIME ONLY wHEN I CHANGE A DRUM THE PRINT WILL BE GOOD WHEN 200 COPIES CONTINUOUSLY TAKING THE DRUM DAMAGED IT MEANS SMALL CRACK ON THE DRUM AT THE FRONT DOOR SIDE...


Hello,
first, did you install complete Canon original drum unit or just replaced with not genuine low quality drum?
Maybe the problem is in bad quality of drum.
In original drum unit you get whole unit with new drum, blade and charge roller.

Second, you should inspect the developing cylinder, he is magnetic and in some cases something like paper clip or other metal dirt can stuck on it and cause breakage or damage of drum surface.
I recomend you to remove the toner unit, vacume it and check for foreign materials, also rotate the developing cylinder and look for damages or foreign materials.

Hope that something of this will help!

Copy is very light. Cannot open the MENU & hence cannot adjust the darkness of the Copy.


First off all to go to menu Press star (Additional function) - 28 together and again star Go to Function - Density and increase/ decrease the number. DE - DC- 24 Dev - 15 Off - 128 Den - 7-9 And again There may be a number of reasons for a light copy 1. Drum - change the drum if it is run above 10 - 20000 copies 2. Blade - changing the blade simultaneously to improve the copy quality
Thanking you.

Why did you do ccd-adj before cleaning the optics?

in copiers front door must be sheet with numbers that are factory input, do the clear all, and then set the values from paper in service mode.

Need more quality


First, put all the settings back the way you found them, There should be a label on the inside of the front door with the original specs. Then set the ip_ofst and pri to the specs on the front of the drum unit. Then run d-Gamma under function>DPC and then run thru the procedure in function>dens. If you still have troubles then dump out the toner out of the developer unit and start with fresh toner.
