Description: Opening the cartridge door opens the cartridge door switch (SW301) and disables the +24 V to the high-voltage contacts on the print cartridges.
Remedy: 1. Remove the left cover, and then open and close the cartridge door. Determine if SW301 closes when the door closes. 2. Make sure that the two connectors from the engine control PCA to the switch are securely installed on the switch contacts. 3. Replace SW301 if the message persists.

Display: Install black cartridge
Description: The product checks for the presence of a print cartridge at start up and anytime the top cover is closed. At start up or when the top cover is closed, a high-voltage bias is placed on the print cartridge's developer roller. This message appears if the print cartridge's antenna is unable to detect the high-voltage bias.
Remedy: 1. Make sure that the sealing tape on the print cartridge has been removed. 2. Verify that the print cartridge is correctly installed. 3. Inspect the high-voltage contact on the print cartridge and in the printcartridge cavity to make sure that they are not damaged. 4. If the messages persists, install another HP print cartridge. 5. Make sure that the engine controller PCA is correctly installed.

Display: Jam in cartridge area
Description: Photosensors PS913 (media width sensor), PS912 (top of page sensor) and PS915 (fusing assembly exit sensor) detect paper in the cartridge area of the product. If paper arrives at these sensors too early, leaves the sensors too late, or is present at the sensor when not expected, an error message is displayed.
Remedy: 1. Make sure that the paper meets specifications. 2. Open the top cover and remove the print cartridge. Remove any paper or paper fragments present. 3. Lift the registration flap. Make sure sensors PS913 and PS912 move freely. 4. Open the straight-through output door and verify that PS915 moves freely. 5. Make sure that the connector at J203 and J206 on the engine controller PCA are seated.
Code: -
Display: Jam in output bin
Description: This error occurs if the duplex reverse photosensor (PS918) or fusing exit sensor (PS915) detect unexpected paper.
Remedy: 1. Make sure that the paper meets specifications. 2. Open the rear duplex jamrelease door and clear any visible paper. Verify the duplex-release sensor flag moves freely. You might need a pen light to observe the flags. 3. Open the face-up output door and the verify the exit sensor flag in the fusing assembly moves freely. You might need a pen light to observe the flag. 4. Verify that the following connectors are seated on the engine controller PCA: . J208 duplex reverse . J206 fusing exit

Display: Jam in Tray 1
Description: Solenoid (SL1) controls the feeding of paper from Tray 1. When the solenoid is engaged, the Tray 1 pick roller makes one rotation and advances paper into the paper path
Remedy: 1. Inspect the Tray 1 pick roller. Verify the roller is installed correctly and in good condition. 2. Print from Tray 1. Determine if the Tray 1 roller rotates. Listen to determine if the solenoid (SL1) is engaged. 3. Remove the left cover. Determine if solenoid (SL1) is correctly installed. Make sure that the connectors on the solenoid and at J4 of the formatter PCA are seated. 4. If the error persists, replace the solenoid (SL1).
Code: -
Display: Jam in Tray 2
Description: Solenoid (SL2) controls the feeding of paper from Tray 1. When the solenoid is engaged, the Tray 1 pick roller makes one rotation and advances paper into the paper path.
Remedy: 1. Inspect the Tray 2 pick roller. Verify the roller is installed correctly and in good condition. 2. Remove Tray 2. Lift the Tray 2 paper present sensor flag while printing from Tray 2. Determine if the Tray 2 roller rotates. Listen to determine if the solenoid (SL2) is engaged. 3. Remove the right cover. Determine if solenoid (SL2) is correctly installed. Make sure that the connectors on the solenoid and at J1104 of the connector PCA are seated. 4. If the error persists, replace the product.
