Learn how to clear a paper jam error on HP ENVY 7640, Officejet 5740, and Officejet 8040 e-All-in-One printer series.

Step 1: Look for jammed paper

Paper jams can occur in multiple areas of the printer. If you cannot find the paper jam in one area, continue to the next area until you locate the jam.

Step 2: Clean the paper feed rollers

Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.

Step 3: Reset the printer

Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again.
  1. With the printer turned on, disconnect the power cord from the printer.
  2. Unplug the power cord from the power source.
  3. Wait 60 seconds.
  4. Reconnect the power cord to a wall outlet and to the printer.
    note:
    HP recommends plugging the printer directly into a wall outlet.
