Paper feed on my Konica 7020 is jamming can you help?

Most likely all you need is to clean the rubber feed rollers. Use alcohol.

I would try taking some cleaner such as fantastic or formula 409, remove the paper trays and clean the feed rolls then open covers and clean any rollers in the paper path.
You can also use rubbing alcohol, but a soapy cleaner tends to do better.

goes through below link and download the manual and try to clean the paper pick up roller and check i think it will solve your problem .......

Does this happen when he orginals go thur the document feeder? How does the copy look if the orginal is placed on the glass. Vertical feed problem mite be dirty rollers or dirty clutch,

Please check the sensors and actuators ,open & close front door to reset nisfeed.Clarification Top feed = Automatic Document Feeder?If YES,please verify misfeed paper beetween coverplaten and feedbelt(Yellow).Is necessary disassembly the ADF.Good luck.You will find a little paper.

I strongly recommend a service tech. It sounds like you will need a PM kit,fuser claws and a few DFP rollers.

Normal 0 I suggest you get a sheet of Card Stock (Heavy paper) and place it in the feed way. Then press the print button applying a slight amount of pressure on the Card Stock so it will feed through the printer. The reason for this is in some cases I have been able to clear the paper track of debris that was deposited there over time.
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud

One very major we see with RADF's is that someone has pulled a jam in the reversed direction and by doing so has pulled a switch actuater out of position , I suggest you check each switch that you can to see if the switch /actuater is not loose or out of position . Next try cleaning feed tires with alcohol and paper towel to ensure proper feeding.
