For the paper jam you remove the back cover and clean the 4 rubber rollers with alcohol, you can rotate the rollers forward while you clean. For carriage jam you start by cleaning the encoder strip that runs across behind the carriage unit, the clear strip with black bars on it, you can wipe with a Q-tip damp with alcohol. If no help you may need to take apart and clean dried ink off of the service station on the right.

Black vertical lines on faxes sent using auto document feeder

If you lift up the lid on your scanning device you will notice a glass strip about 1 inch thick and then the large area of glass used for flatbed scanning. The 1 inch strip is used for ADF scanning. Because your papper is moving across the glass strip, any dot, smudge or scratch will affect your scanning and cause verticial lines down the page. Sometimes the dot is not visible to the eye. Get some glass cleaner that has alcohol in it and thoroughly clean the glass strip and it should solve your problem. If it turns out to be a scratch on the glass then cleaning won't help.

Thick verticle line on copies and scans

Sounds like the issue is with the scanner bulb. May not be moving across or warming up to full capacity.

Make sure the scanner is plugged in directly to the wall and not into a surge protector or a power strip. If problem is still there and you are in warranty you will need to replace the unit. If OOW then you should call and see if you can repair or upgrade the unit at a discounted price. If you want to speak to someone in English tell them you want mac support - they are in Canada.

G85 printer making horizontal strips

Check the scanner cable and the status of the LED's in the scanning head. Unluckily, you printer is disposable, to HP that problem will mean to discard the entire printer and replace it for a new one if it's still under warranty.
