Laser Jet printer is printing test pages automatically

@Prasenjit88

 

Welcome to HP support community.

 

Perform a power reset

  1. Turn on the printer, if it is not already on.
  2. Wait until the printer is idle and silent before you continue.
  3. With the printer turned on, disconnect the power cord from the rear of the printer.
  4. Wait at least 30 seconds.
  5. Plug back the power cable straight to a wall outlet without any surge protector and printer.
  6. Turn on the printer.

Update the printer firmware

Refer the steps mentioned in this HP document for the steps:- Click here

 

Calibrate the printer to align the colors

1. On the printer control panel, press the Setup button.

2. Select the following menus: ● System Setup ● Print Quality ● Color Calibration ● Calibrate Now

3. Select OK to start the calibration process.

4. A Calibrating message will display on the printer control panel. The calibration process takes a few minutes to complete. Do not turn the printer oƫ until the calibration process has ƭnished. Wait while the printer calibrates, and then try printing again.

 

Let me know how it goes.

Can you describe or attach a sample of the test pages you're getting? It would help tremendously in figuring out a solution.

Thanks.

That looks like the output you would get if sending a print job with an incompatible driver or bad connection cable.  If the printer is networked then it could be a user inadvertently sending a job. If you have the printer connected to network,  the easy way to see if another user is sending the print job is to change the IP address of the printer and see if these print stop.

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.

What you're seeing is actually character representations of the printer data being sent to the printer, but it is all computer code that is supposed to be deciphered by the printer if it is given the right info to decode it correctly. It is caused by any number of possible issues: 1) the printer driver for that printer has become corrupted, by any number of causes, including operating system software updates; 2) the wrong printer driver is being used for that printer; 3) a different printer model is configured to send it's data to your printer instead of the printer it's supposed to go to (i.e. the wrong IP address on a network is set, as repairatrooper alluded to). Changing the IP address of the printer and correspondingly in your printer driver should isolate it from any errant files being sent from other users/computers that may be causing the problem. If it then continues, then it may be a problem with your computer driver. Delete and reinstall driver.
