Hi fourthphoto,
There may be some debris on the ADF rollers or areas of the platen glass that may be causing the vertical line; cleaning these areas may resolve the issue. To do this, please follow these steps:
1. Please turn off the printer, then open the left-side cover of the ADF. Inside of the cover, you should see several rubber rollers.
2. With a moistened cotton swab (you can moisten the swab with water or glass cleaner), please clean each of the rollers, being sure to rotate the rollers with the swab instead of directly touching it.
3. Once the rollers have been cleaned, please close the ADF cover.
4. Next, please open the printer cover to get to the platen glass. With the moistened swab, please clean the small strip of the glass that is off to the left hand side, separated from the main scan area of the glass.
5. Once the strip of glass on the inside cover has been cleaned, please attempt to photocopy from the ADF again. Hopefully, the copy will be clean this time.
If you still experience difficulty, we ask that you please call 1-866-261-9362, Monday - Friday 10:00 a.m. - 10:00 p.m. ET (excluding holidays) for further assistance. A Canon technical support representative will be happy to help. There is no charge for this call.
