Canon IR5020 background when using feeder

[Desert Rat]

This is driving me nuts. When I got to the customers I made some copies
off the glass. Looks ok. But when using the feeder it puts background
on the page. Try to light it up and it gets worse, then the density drops
but still have background.
Here's what I've done. Cleaned optics, both side of platen and scan
glass and mirrors.
Pulled the dv station it looks normal. I saw the toner band on the drum
so I pulled it and cleaned the erase lamp, cleaning blade, pot sensor &
cleaned the scum from the sides of the drum. There was not that much
scum on the drum and the chargers looked fairly clean. Only 37K on the
wires. The pre-transfer charger was dirty and causing small short pencil
thin lines from .25" to across the page.
I did a DC-Con clear and re-entered the values. Now it displays European
paper size and I have not found where to change it back. Although I
just read a post from screwtape for Waffu22 and that sounds like where
I need to go.
Also this machine came up with an E602-0003 code. I ran HD-check,
that seemed to take care of that. But the original problem remains.
I have had this code a couple of times on this unit. It only has 570K
copies.
I only have the first version of the IR5020 manual. I did get something
else but it only listed the different part numbers. That publication is
TP03 110.
Anyone got an answer for this problem?
I am thinking it has to be changing either the primary charge or the
dv bias. I hope it is not related to the E602 code. I am not able to
download or update firmware. I do not have that centronics cable.

If anyone has a suggestion it would be appreciated, this customer is
a printer.

Thanks

Have you checked your hinges on the DADF
I had a simalar problem on a iR1022 (Know it's a total different m/c but still the same fault, Shadowing/shading from the feeder)

I found that the rear of the feeder was higher then the front

Just an idea

602 is headed for a hard drive failure, you can get a IEEE1284 cable just about anywhere. Also, I am not sure, but I think the 5020 if it has a network card in it supports FIXEDIP software installation. I think it may have been the first box to support that. Try starting it with the 1&7 held down and see if it enteres FIXEDIP mode.

Check the height.
Try cleaning the white plate.
Try a CCD adjust.
Try replacing or swapping the lamp.

I agree with Screwtape.

Do a CCD adjust. Place ten sheets of white paper on the glass and after highlighting ccd adj, press OK. I had this exact problem and the ccd adjust fixed it, although i was back several days later for pencil thin lines, lead to trail.. If i made a copy without AE it had background again and even darker lines. Only this time it was very dark, even on the lightest setting. Found out that i had to to change the two shading adjustments to a higher number. The ccd-adjustment set the shading numbers to around 70 every time. The P-print (birth certificate) had a value of 170. I went midway between the new adjustment setting and hte original default (120) and viola. Perfect prints with nice density and no background at any setting.

Thank you for your suggestions. I was in error on the model number.
I should have posted IR6000 instead of 5020. That's a different
problem.
I was not sure if it could have been related to the E602 code.
I thought that cable had some kind of imbedded chip?
Thanks for the number I will get one. Then I will start preparing.
I have to go back tomorrow and look at his finisher for not jogging
perfectly before stapling anyway.
Scretape, I will check those items you and Mr. B suggested.


Thank you I will post the results

i believe screwtape is close to the problem about the background. also i have had a ground problem at the back of the transfer assbly,around the paper guides and the stripe at the back. i have seen these cause this type of problems.the 602 code 03 has to do with the reading. or writeing to the hard drive or how it tried to store the info possibly for a print job.having had it before.you should try reformatting the hard drive and reloading software.this can be do with a crossover cable and your laptop.using a service support tool.also certain hard drives have been known to fail over and over causing this error.seen this several times with these machines.most hard drives don't recover from a 602-02.there are 4 codes for the 602. hope you find your fix from theses.

[Desert Rat]

Bigredone,
Thank you very much, I have the service support tool. The crossover
cable? Is that the IEEE1284?
Now all I need is the firmware and a new HD. This is about the 3rd or
4th time this machine has popped this code.


Thanks

You can try a IEEE1284 Bi-Centronics cable but you laptop must support it. It must have a IEEE1284 Bi-Centronics port. If your laptop does not have a IEEE1284 Bi-Centronics port but has USB ports instead, then you will need the Canon USB to parallel cable and the the nethawk driver must be installed onto your laptop. You can get the nethawk driver with the firmware and you must set this up within your device manager>USB Controller on your laptop.

If you try flashing your harddisk and it crashes again with 602, replace it. There are new type HDD that requires a updated HD format data file, I believe its v16 so look out for that. I do believe you must use a parallel connection with a iR6000. The iR6020 you would probably be able to flash with a crossover cable. Its been a while for me on these machines.

Goodluck.

Screwtape,
I have never done this or seen this done, My laptop does not even have
LPT1 port.
Any ideas on where I could get the cable I need and the other things
you mention?

Thanks

How can I down load this post to read off line?

the crossover cable is a cat5/cat 5/cat5e ethernet cable .similar to network cable rj-45.just wired different.should be able to pick one up at alocal computer hardware shop.good to have for updating those canons. if the machine you are having the problem is used as a printer or if you know it has a print board in than this is the way to go.as stated earlier if the version that is on the machine ,try the "1 & "7" for the fixdip mode.just set your laptop to be on the same network ip and subnet settings.,so be sure to get your network setting for the machine if possible before starting all of this.hope this helps .

[Desert Rat]

bigredone,
This machine is not networked, and I believe it does not have the boards
in it for networking. I will double check this today.
A friend mentioned holding down the "1" and "9" key,then power up. I am
told this will make it do a scan disc. Is this right. He usually works on the
IR600 through 8500.

Thanks for the advice I will see that machine first today.

The cable must be purchase by a Canon dealer. You can try to search around, Ebay,Amazon, ETC.

If you haven't done this before, its not hard but, at first its trial and error.

[Desert Rat]

Screwtape,
Thank you for that information, I can't help but wonder why it must
be purchased by a Canon dealer if I can pick one up at an electronics
store?

In regards to the machine.
Next time I post, someone ask me "What was the last thing I did there?"
Turns out last month just before Christmas I stopped at this customer
to clean some spots off the glass he could not find. I noticed that off
the glass the solid was not to my liking. The customer had said nothing.
So I adjusted the front end of the primary charge wires 1mm farther away.
After doing all the things suggested, which did help, I put the wires back
and did a forced potential sensor adjust, plus find all the places where
I needed to set for paper. Everything works well now. I ran 45 sets of
55 stapled. They all came out perfect.

Thank you everyone for lending your expertise to this old rookie.
Now to peruse the hard drive problem. I was so happy to get it back on
track and to the next call I forgot to find out what size HD is installed.
I will start looking for a cable and the software.

Thanks again

DR
