The Quick Answer
If your HP DeskJet 2755e is reporting a paper jam but there is no paper inside, you have a "false jam." To fix this, first unplug the printer to reset the sensors. If the error persists, you must clean the gray rubber paper pick rollers located inside the input tray using a damp, lint-free cloth.
What Causes a False Paper Jam?
Your printer doesn't actually "see" a jam. It assumes there's a jam if the paper feed rollers fail to pull paper into the machine within a specific timeframe, or if a tiny scrap of paper is blocking an internal optical sensor.
Step 1: The Hard Reset
Sometimes the printer's logic board gets confused. A hard reset can clear the error state.
- Turn the printer on.
- Unplug the power cord from the back of the printer and the wall.
- Wait a full 60 seconds.
- Plug it back in and turn it on.
Step 2: Cleaning the Pick Rollers
Over time, the rubber rollers that pull paper into the machine accumulate paper dust and lose their grip. When they slip, the printer thinks there's a jam.
- Unplug the printer and remove all paper from the input tray.
- Shine a flashlight down into the input tray to locate the gray rubber rollers.
- Dampen a cotton swab or a lint-free cloth with bottled or distilled water (do not use tap water or alcohol).
- Press the swab against the rollers and rotate them upward with your fingers to clean the entire surface.
- Allow the rollers to dry completely (about 10 minutes) before inserting paper.
Step 3: Checking the Carriage Path
Open the ink cartridge access door. Look all the way to the left and right edges of the track. Even a torn corner of a piece of paper the size of a postage stamp can block the carriage sensor, triggering a jam error. Use tweezers to remove any debris.
