Question about Canon NP 6035 Copier

1 Answer

Canon np 6035 copies to dark

We have a canon np 6035, and every 4 months or so the brightness of the prints begins gradually getting darker, so we call a service tech in, who does something with a tiny hole in the front of the unit to adjust the darkness. We pay him a minimum of 100 dollars per visit. Not very cost effective for something he spends 2 minutes working on. I have searched the internet for a service manual to tell me what that mysterious little hole does, and how we can begin adjusting this ourselves without paying out the nose :)

Anybody know how we are supposed to use this little hole of mystery?

    I dont know where the inappropriate came from but it wasnt me, please dont flame me out. This is the first time I've come back to the site since posting the issue, so please dont fly off the handle.

    Thanks for the input, although we ended up just calling the tech in. He think our drum needs to be replaced, but managed to lighten it again for us.

He is probably adjusting the exposure voltage. If you take a flashlight and look inside the small hole, you should see either a "+" or a "-" on a plastic part. Turning it clockwise will increase the voltage, and counter clockwise will decrease the voltage.
If you are going to do this, I would suggest using a plastic screwdriver to turn the "Pot" (Potentiometer)

Doing with by yourself will be a hit or miss effort. Also it is not recommended doing this without knowing what you are doing.

FYI, If you are going to turn the "Pot" on your own, I would suggest turning it very little and testing a copy, and then doing this again and again to make sure you are helping the situation or hurting it.
Good luck.
Hope this helps.

    Inapropriate feedback?!?! That's the thanks I get for trying to help someone. I could have said, quit being so cheap and pay the technician for his work. The technician had to go to school for training to learn how to fix your machine. The tech also has bill to pay like you, and needs to earn a living like you. If you don't feel like paying him, then try fixing your own machine and screwing it up. Then see how much it will cost to buy a new machine. That will be very cost efficient.

    I spent my own time trying to explain how to make your own adjustment and this is in the FREE SECTION so IM not making a penny. And you have the gull to give me an inapropiate feedback.

    Well, good luck with your old copier and your soon to be new copier which you will have to buy once you destroy your old one.

    Hey.. Sorry about venting about the bad rating. It was my first Inappropriate rating after trying to help 95 people in the last 2 months. And all of my posts were under the free section, just trying to see if I can help some people out there.

    Thanks again for clearing up the bad rating.
    Maybe I can help you with something else in the future.
    Have a good day.
    Mac =)

First of all did you clean the optic? How about did you replace all of the corona wires? Also, did you clean the scanning lamp as well? Also when you had fitted the new drum, did you use a brand new one or a different one, did you clean the drum with rubbing alc. If all that was done, do a "AE" adjustment in service mode using white paper on the copy board glass. Also, go to the addictional funcation mode and go to expossure adjustment and make it lighter. Or as a last effort adjust the corona hieghts of the primary corona wires. Good Luck...
