HP LaserJet 1600 Printer - Clear Paper Jams
This section contains information about clearing jams.
Figure 1: Paper path
Common causes of paper jams
Occasionally, paper or other print media can become jammed during a print job. Some causes include the following events:
Where to look for jams
Jams can occur in these locations:
The following illustration identifies the stages when jams can occur.

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.)
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.
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.

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.
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.
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.
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.
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.
