Hi,

I would like to inform you that this might cause due to dirty paper rollers hence Please click here and follow the instructions to resolve this isse.

The printer does not feed paper from the tray and then states that there is a paper jam. I have removed all paper and there isn't a paper jam. It will feed paper through the lower roller and straight into the printed paper tray, but will not feed a new sheet.

check there is not any paper jam also

I have serviced an officejet pro L7580 which was showing a paper jam error when powered on. our customer had had a paper jam and removed the paper . I found small peices of paper in the pick up assy gears. If you remove the rear door, you need to check the 2 small white gears on the left. turn the roller slowly by hand and clear any paper stuck between the teeth. (they may be very small).

after doing this....no more paper jam errors for me!

The Pickup roller of the printer is not properly aligned, send the printer to repair and see the jam
