Common causes of paper jams

Occasionally, paper or other print media can become jammed during a print job. Some causes include the following events:

Cause
Solution
The input trays are loaded improperly or overfilled.
Remove any excess paper from the input tray. Make sure that the paper does not exceed the maximum stack height mark in the input tray.
Tray 2 or optional Tray 3 is opened during a print job.
Make sure that Tray 2 or optional Tray 3 is closed.
Too many sheets accumulated in the output area or sheets blocked the output area.
Remove any accumulated sheets and clear the output area. For information about clearing jams from the output area, see Output jams.
The print media that is being used does not meet HP specifications.
Use only paper that meets HP specifications. For more information, see the HP LaserJet Printer Family Print Media Guide or go to http://www.hp.com/support/ljpaperguide .
The environment in which the print media was stored is too humid or too dry.
Make sure that the printer environment is within humidity specifications. For more information, see Printing and storage environment.
A supply item is installed incorrectly, causing repeated jams.
Verify that all print cartridges and the ETB are correctly installed.
Print media is skewed.
Input tray guides are not adjusted correctly. Adjust input tray guides so they hold the print media firmly in place without bending it.
Do not fan paper. Fanning can create static electricity, which can cause the paper to stick together.
Print media is binding or sticking together.
Remove paper, flex it, rotate it 180 degrees, or flip it over. Reload paper into the input tray.
Print media is removed before it settles into the output bin.
Reset the printer. Wait until the page completely settles in the output bin before removing it.
Print media is in poor condition.
Replace the paper.
Print media is not picked up by the internal rollers from Tray 2 or Tray 3.
Remove the top sheet of paper. If the paper is heavier than 163 g/m243 lb, it may not be picked from the tray.
Print media has rough or jagged edges.
Replace the paper.
Print media is perforated or embossed.
This paper does not separate easily. Feed single sheets from Tray 1.
The printer supply items have reached the end of life.
Check the printer control panel for messages prompting a replacement of supplies, or print a supplies status page to verify the remaining life of the supplies.
Print media was not stored correctly.
Replace the print media. Print media should be stored in the original packaging in a controlled environment.

Where to look for jams

Jams can occur in these locations:

  • Inside the printer

  • In input areas

  • In the output area

  • Paper path

The following illustration identifies the stages when jams can occur.

Figure 2: Jam locations and stages

1 - Pickup stage
2 - Feeder stage
3 - Transfer/feed stage
4 - Fusing/delivery stage

Find and remove the jam by using the instructions on the following pages. If the location of the jam is not obvious, first look inside the printer.

Loose toner might remain in the printer after a jam. This problem should resolve itself after a few sheets have been printed.

Each section below corresponds to an area where a paper jam could occur. Use the following procedures to clear the jam. In all cases, grasp the jammed paper by both corners and pull slowly to remove the paper.

Jams inside the printer

Use the following instructions to clear jams from inside the printer.

CAUTION: Jams in this area might result in loose toner on the page. If you get toner on your clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.)
  1. Open the front door.

    CAUTION: Do not place anything on the transfer belt, which is located on the inside of the front door. Otherwise, the printer may be damaged, adversely affecting print quality.
  2. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper.

  3. Close the front door.

Input jams

Tray 1

If the jammed paper is easily accessible from the outside of the printer, grasp both edges of the paper and firmly pull to remove. Otherwise, follow the directions for Tray 2.

Tray 2

Open the front door of the printer and remove paper as indicated on the jam instruction label, located on the interior right side of the printer. Input jams are indicated on the label with the number 3.

Output jams

Jams in the top bin

CAUTION: Jams in these areas might result in loose toner on the page. If you get toner on your clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.)
  1. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper from the top bin.

  2. Open and close the front door.

Pickup delay jam

The printer performs the retry control, which executes the pickup operation three times, to retrieve the pickup delay jam caused by the pickup error. When the registration paper sensor (SR1) does not detect the leading edge of the paper within approximately 2.5 seconds (4.5 seconds for optional cassette) after the pickup solenoid (SL1) is turned ON, the CPU tries to pick up the paper three times.

Pickup stationary jam

The CPU determines the pickup stationary jam when the registration paper sensor (SR1) does not detect the trailing edge of the paper within approximately 8.6 seconds after it detects the leading edge.

Delivery delay jam

The CPU determines the delivery delay jam when the fuser delivery paper sensor (SR4) does not detect the leading edge of the paper within approximately 6.6 seconds after the registration paper sensor (SR1) detects the leading edge.

top

Wrapping jam

The CPU executes the wrapping jam detection after it assesses no delivery delay jam. The CPU determines the wrapping jam, when the fusing delivery paper sensor (SR4) detects the paper absence before the time equivalent to paper passage of its length minus 40 mm (1.6 inches) after the SR4 detected the leading.

top

Delivery stationary jam

The CPU executes the delivery stationary jam detection after it assesses no wrapping jam. The CPU determines the delivery stationary jam, when the fuser delivery paper sensor (SR4) detects the paper presence after the time equivalent to paper passage of its length plus 50 mm (1.9 inches) from when it detected the trailing edge.

top

Start-up residual paper jam

The CPU determines the start-up residual paper jam when either the pre-fuser paper sensor (SR5) or the fuser delivery paper width sensor (SR4) detects the paper when the initial rotation is started.

top

Door open jam

The CPU determines the door open jam, when either the pre-fuser paper sensor (SR5) or the fuser delivery paper width sensor (SR4) detects paper when a door open is detected.
