Re: faded paper at the top canon ir 2520

if you mean its new yes its new.

NO what copier tech means is the machine tilted to one side or front to back..

this is a known problem wit MOST brands of copiers.

take a CARPENTERS LEVEL check the level from one side to the other.. then front to back... just like if you were laying a foundation for a shed/house .. or repairing a floor that has been ripped up.

frankly from the sounds of it you should turn this job over to a MORE qualified person. you are clearly out of your paygrade with this issue.

yes I am new to do that work but I am in a rare place no one can go to fix it so i have to do it on my own and sorry cause i didn't understand the meaning of level cause English is not my first language anyway yes the machine is leveled and the problem happened after i used the machine even it says replace the toner until that faded appears then after replacing the toner and i didn't toner installation from the menu still the same faded i think nothing to mention with the machine level

take a piece of legal paper... place it front to back over the 1st 1.5 inch of platen glass...

keep the adf up and run 20 pages of "sky shots"

then run your auto calibrate program

it should either fix the issue or error out

if it errors out report back with error code.

print out error log and upload it using PDF format

Have a read of the service manual then remove & check the toner covering of the developer unit on page 151 (it should have a good even covering)

Looks like either mag roller is poor covered in that area for some reason(leveling in example) or dusty poly mirror.

Canon lasers are generally well-sealed and if the meter reading is genuine I would not be dismantling the laser. However, this machine is the budget version of the IR2270, etc series which had a problem with leaking hopper pump assemblies and would dump toner over the laser slit glass which resulted in the copy issue described here.
There is the possibility that some toner fell on the laser slit glass during replacement.

Well, thanks for correcting me I forgot slit glass which is way more probable to be dusty than laser poly. I just assumed any tech would started by cleaning slit etc.

I don't think we are talking to a tech in this case.

it was faded before replacing the toner cartridge

Re: faded paper at the top canon ir 2520

it was faded before replacing the toner cartridge

so either you have a dev unit failing or not properly initialized

crap toner can cause these problems.

also HV / dev / drum / transfer contacts can cause it.

on other brands I have seen a drum bearing/bushing that is wobbled out can cause it...

are you sure the image is good on the belt?

are you a trained tech on anything? your profile is VERY Vague.


are the transfer rollers in the belt area are lifting..

no I am not going to go back thru the plethora of suggestions do see what others have recommended
