Registration Issue & UNDO service mode 1 setting

[Discount Printing Service]

I just got a Canon c3220 yesterday. The print quality looks good as far as the drums but all 4 color (cmyk) all print about 1/32" off from each other in the direction the paper travels. I checked the itb and cleaned it & its rollers with alcohol & a cotton pad removing some toner but not an excessive amount. I local tech told me to go into the service menu & had me reset a few things. Now when I turn on the machine I do not see a tab for PRINT, all I see is 3 tabs COPY, MAILBOX & SCAN...PRINT tab has disappeared. Can anyone help me get it back. The machine has an ImagePass C1 on the back. I also need help getting it connected to my 10/100 ethernet switch as a TCP/IP connection. I am affraid the service people I talked to on the phone told me to do something that has screwed it up. Also as far as registration problem I was told it could be 1 of 3 things, first the transfer belt or itb which I don't think is it because registration is consistent but all out equally about 1/32", second they said the laser may need to be recalibrated (can anyone tell me how to do that?) and third it could be a board problem...most machines I have worked with have a utility in user mode or service mode to adjust each color to get registration. I am on a very tight budget and I don't want to pay too much or pay for something that doesn't need to be done to service tech. I am a commercial printing so i am technically oriented & any help would be greatly appreciated! Also I would like to get a pdf copy of the service manual & the full operation/setup manual (all it came with was a copying guide). Thanks for any help!

I fixed the service mode problem but not the registration issue

The tech I talked to earlier today had me clear MMI in the service mode 1 menu. I checked the IMG-CONT setting which was at 0. I reset it to 3 and rebooted the machine, the PRINT tab is back on the screen...YES I AM GOOD!!!

Anyway I still need some help with the registration problem

Yes, when clearing MMI those type of things happen, especially when your not aware of them. Anyhow, clearing MMI would not help you get rid of the registration problems, clearing DC sometimes helps but chances are it will be back. What always helps me, is cocking the lasers back into there original right position and reloading or upgrading firmware along with DC-CON and R-CON. It sometimes doesn't seem to corporate when you try one or two times with this procedure, but don't give up, continue. If you are not familiar with taking the laser's out, they are located under the reader unit, where the paper delivery is. You can rectified this issue without replacing any parts, it take time and patience but it can be done. Good luck,

All good suggestions so far but the one thing I do first with this prob is do a QUICK auto grad adjustment. Dont do the full grad adj but the quick one will sometimes snap the reg back into focus. It lays a different set of patches down that sometimes aligns the lasers automatically. If that has no effect then next would be a DCon clr.

good luck

Printing out the P-Print BEFORE doing any clearing or settings changing.

Many good suggestions being offered here,,, but the first step to NOT overlook, is the importance of printing out the P-Print BEFORE doing any clearing or settings changing. We techs take this for granted, but our friend here has said that he is not a technician, especially not one trained on this box. Hopefully this copier arrived with a P-print tucked away somewhere.

To initiate the print: service mode > copier > function > misc-p > P-Print
This step should be taken before clearing, otherwise you will get a printout of factory baseline specs before the machine has been tweaked prior to shipment.

Another physical thing to check/replace, is the drive gear on the ITB drive roller, the cluster & driven gear on the copier itself. A little play in the ITB gear sets up the same scenario as the dirty belt and rollers.

thanks for all the suggestions, i will give them a try. To clarify, I am a offset printing press tech not a copier tech but I am tech savvy in general. thanks for the help I will repost with my results.

Also if anybody has a Canon service manual for this C3220 I would like to get a copy, pdf form would be fine.

Thanks,
