Jam Codes?If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

there is no jam code in the display it only says clear paper path...and it keeps on coming back after copyingComment

Just wrote an entire response to an 8500. LOL 8530 is an old one. Try removing the pre-transfer corona assembly and see if the problem clears up. they use the same HVT and it can short the separation. The other thing I would suggest is to crimp the connectors on the DC controller and any on the HVT That are crimpable. Have you ever done any crimping on those connectors. Saying yes would make this easier lol.Is the glass half full or half empty? I say neither. The glass is obviously full, full of potential. The potential to hold more water or the potential to quench a thirst. Life is all about how you see it.Comment

I have seen where the black rubber registration roller will shrink in diameter enough that the paper will not be driven thru the registration rollers far enough before the registration roller clutch shuts down and stops the paper. If this is the case the trailing edge of the paper will be still stuck between the nip of the rollers. You can repair this by spiral wrapping some black tape over the roller which will increase its diameter enough to make it work again until you can replace it.Comment

so far our machine is working well as ive followed the suggestions given and i thank you for that!!
but now another problem arises which is when we use the 100% ratio/zoom the output is blurred in which you cant really read the text.but when we try to reduced it to 89% and below the copy is clear but above that ratio(89%) copy is not good..ive cleaned the railings of the lens&scanner..but still the same...suggestions please..

regarding the machine above we are using the A4R paper and also when i make a black copy not the entire paper is covered...a two inch white space is left out..Comment

My first thought was the lens rail, but having done that...... did you clean the home position sensor for the lens? I would also check the scanner cable tension and adjust it. is the white at the lead edge? is the copy in focus if you use letter or ledger?Is the glass half full or half empty? I say neither. The glass is obviously full, full of potential. The potential to hold more water or the potential to quench a thirst. Life is all about how you see it.Comment

Take the time and initiative to look up the jam codes, get the jam codes, and I'll be glad to help. =^..^=If you'd like a serious answer to your request:

Make sure that the correct door specifications are entered into the Adjust>laser>LA-Delay. Also do a CCD adjust and check spec values for CCD.

Since your are dealing with a analog machine there is no laser timing to worry about. Checking the lens rails was the first best option since the lens does not verify its position as it shifts to different reduction positions. Once it gets out of focus it will stay out until it does a home position check. I would guess that if you were to turn the machine off and on and mark where the lens stops each time you will find it to be different. If this is the case you have either a lens drive motor issue or the DC Controller is not controlling it properly. This can easily be a fauty connection issue which is what I would check first. I have seen both the motor connection and the DC Controller connection cause this. One second of poor contact throws off the timming and the lens will be out of focus. You can sometimes hear the motor stumble when the drive is inconsistant. Good luck.Comment

regarding the machine above we already refer it to the canon tech..after doing everything we can to solve the problem..the canon tech also had a hard time finding the fault but still the same problem..the final say is to condemn the unit!!thanks for the help youve done..Comment
