This document applies to the following printers:
  • HP LaserJet Enterprise 600 M601
  • HP LaserJet Enterprise 600 M602

  • HP LaserJet Enterprise M606
This document applies to the following errors:
13.A2.D2, 13.A3.D3, 13.A4.D4, 13.A5.D5, or 13.A6.D6 paper jam error usually occurs when the paper does not leave the specified paper tray.
Paper jams might occur at any point in the paper path.
The X indicates which tray’s sensor did not detect the paper, and the Y indicates from which tray the paper came.
For example; a 13.A2.D2 indicates that the paper jammed before reaching the tray 2 feed sensor when pulling paper from tray 2. In this case you would look for any jammed paper in or behind tray 2. If no paper is present, then it is most likely that the printer failed to pick up the paper from the tray.
There are several reasons 13.Ax.Dx error can occur.
The following instructions will show you how to:
  1. Verify that the paper tray guides are not set too tight or too loose.
  2. Verify that the paper you are using is suitable for the printer.
  3. Verify that the paper is not ripped, folded or damaged in any way.
  4. Verify that the rollers used to pick up and feed the paper are not dirty or worn.
  5. Verify that there are no broken parts on the printer.
  6. Verify that the humidity in your environment is not too high or too low.
  1. Clear any jammed paper from the printer.
    The error code on printer will guide you to where to look for paper. The last number in the error tells you the tray from which the paper was requested. In a 13.A2.D2 the last “2” tells you the paper was being pulled from Tray 2. There would be no need to look at Tray 3 or higher.
    1. Open the indicated tray and remove any jammed paper, and then close the tray.
    2. Open and close the upper TOP cover to allow the printer to attempt to clear the jam.
  2. Adjust the paper guides to the correct size.
    Paper tray guides that are set too tight or too loose are the most common cause of paper jams. The last number in the error code tells you the paper tray from which the printer was attempting to pull paper. As in the example 13.A2.D2, the paper was requested from Tray 2. You would want to check the paper guides in Tray 2.
    1. Remove any paper from the tray.
    2. Make sure that the paper tray guides are set to match the paper being loaded into the tray. The arrow on the guide should line up with the paper size label.
      There is an indentation and label for standard paper sizes.

  3. Load the paper into the tray
    1. Avoid loading paper that is damaged (such as bent, torn, dusty, wrinkled, and curled) as well as paper that does not meet printer specifications.
      1. You can check the supported paper types for the printer in the following documents.
    2. When opening a new ream of paper, gently hold the ends of the stack, and bend the stack in a slight “U” shape.

    3. Firmly hold the ends of the stack and flatten it. This separates the sheets to allow easier feeding from the trays.
      Figur : Separate the sheets
    4. Square the stack using a flat surface, such as a desktop.
    5. Load the paper stack from back-to-front to prevent it from getting caught on the rear guide. Make sure the stack stays aligned and undamaged while lowering the front end of the stack into the tray.

    6. Do not overload the tray. Make sure that the stack of paper fits within the tray, and is no higher than the top of the line located below the down arrows or triangles on the paper guide.
      Do not load thick media, such as labels, in the 1,500-sheet high-capacity input tray. Thick media might damage the tray’s lift mechanism.

    7. Insert and close the tray.
  4. Verify environmental conditions.
    High humidity levels in the paper might cause paper jams, poor image density, blank areas of print, and pages curling when printed.
    In high-humidity environments, paper at the top of the stack can absorb moisture, and it might have a wavy or uneven appearance. If this happens, remove the top 5-10 sheets of paper from the stack.
    Figur : Damp paper
    Most reams of paper are sold in moisture-proof wrapping to keep the paper dry. Verify that paper is being stored in unopened packages.
    In low-humidity environments, excess static electricity might cause sheets of paper to stick together, resulting in misfeeds, paper jams, or poor output stacking. If this happens, remove the paper from the tray and flex the stack of paper again.
  5. Remove, inspect, and clean the tray rollers.
    1. Remove the rollers for the tray that is experiencing the error. The last digit of the error code will tell you the tray for the rollers that need to be cleaned. In the case of a 13.A2.D2 the tray rollers are located in Tray 2.
      The following video walks through removing and replacing the rollers:
    2. While the rollers are out of the printer inspect them for signs of wear. Things to look for are an excessively smooth or shiny roller surface, nicks or cuts in the roller surface or missing pieces. If the rollers show any of these symptoms skip to Step 6 for instructions on ordering new rollers.
    3. If the rollers do not look worn or damaged, dampen a lint free cloth with water and gently clean the surfaces of all 3 of the rollers.
    4. After inspecting and/or cleaning, re-install the rollers into the printer using the instructions provided in the video.
  6. Replace the paper tray rollers.
    If the jams continue after completing the above steps, the rollers in the tray might be worn. To replace the three rollers in the tray, order a roller kit. Use the table below to identify the correct kit part number for your printer.
    Genuine HP replacement parts can be ordered at or by contacting an HP authorized service or support provider.
