Troubleshoot Paper Skew Issues

The paper skew takes place when the movement of pages occurs in the advance mechanism with the movement of the cartridges. This actually results in the improper printing of margins in the paper edge. Let’s discuss how to deal with the paper skew by following the sections that are given below. 

Factors to Understand the Paper Skew

There are several factors by which we can deal with the paper skew in your HP DesignJet printer. They are as follows.

  • Load the paper properly in the paper input tray. This will help you to reduce the possibility of paper skew. 
  • There are a few types of papers that can be affected by the paper skew. We advise you not to use those papers. 

Note: You can use genuine HP papers that are compatible with the DesignJet 400 model. 

Troubleshooting Tips for Paper Skew

When you are inserting the paper in your printer, let the device first check the positioning of the paper. To do so, you can take the help of the paper slider. The right side of the sheets must be in an accurate loading position.

Now press the “Load Media” key to advance the paper until the large margin passes through the paper sensor. Now the printer can work with the total length of the sheet. This will make the printer work with the papers and will not lead to rejecting any page during the printing process.
