HP LaserJet Pro, Ultra M130 – M134 Printers not Picking Paper from Input Tray [Fixed] – HP Printer Warning Lights on HP LaserJet Pro M130 and Ultra M134 Printers

If your printer is not picking paper from its input tray, do the following tasks to resolve this problem.

1. Confirm that you are Using Genuine HP Cartridges – HP Printer Warning Lights on HP LaserJet Pro M130 and Ultra M134 Printers

Although you can use other cartridges in HP printers; however, to get the best result, it is recommended that you use genuine HP cartridges rather than refilled or non-HP cartridges. HP as a company does not guarantee the reliability or quality of such supplies.

Also, if you are using a non-HP toner cartridge, the tasks we provide below might not fix your printer’s problem as they are proven to work with HP cartridges.

If you are not sure of your cartridges’ authenticity, you can check this webpage to find out.

If the cartridge is not genuine, we recommend that you get a replacement cartridge from a reputable store or the HP store.

After installing genuine HP cartridges, check if the issue is resolved.

If the issue is not resolved, do the task below.

2. Examine the Loaded Paper, and then Reload it into your printer – HP Printer Warning Lights on HP LaserJet Pro M130 and Ultra M134 Printers

Your printer’s problem might be because the paper in use is bent, wrinkled, curled, dusty, or ripped. Apart from these poor paper conditions, the paper quality also determines whether the printer will be free from paper feed issues or not.

Here are some guidelines you ought to bear in mind that will help to prevent future paper feed issues:

i. Use quality paper that matches the specifications of your printer.

ii. Don’t store paper in a humid environment; always store your paper in a place that is dry and cool.

iii. Do not load your printer with already-used paper; that is, paper that has been printed on already. Such paper can get stuck to other paper within the paper stack.

iv. Always allow your printer to finish a print job before you reload the paper into the print tray, or only reload paper when you see any of these messages: “Load Paper” or “Out of Paper.”

To examine the loaded paper, and then reload it into your printer’s input tray, do the following steps:

Step 1: Lift your printer’s dust cover.

Step 2: Take out the stack of paper from your printer’s input tray.

Step 3: Examine the stack of paper and confirm that the condition of each paper sheet is good. If you find any sheet that is torn, wrinkled, or bent, remove it from the paper stack.

Step 4: Hold the stack of paper in both hands, and then flex it in a way that a “U” shape is formed.

Step 5: Flex the stack of paper in the other direction still forming a “U” shape.

Flexing the stack of paper in this manner can loosen the individual sheets within the stack.

Step 6: Load the paper stack with the print side face up into your printer’s input tray.

Note: Do not load more than 150 paper sheets into the input tray. Ensure that the print side faces up while the top edge goes into the printer. if the paper you are loading is pre-punched, the side with holes should be at the tray’s left side when you load it in.

Step 7: Push the paper stack into your printer’s input tray.  

Step 8: Adjust the paper width and length guides to rest against the paper stack.

Step 9: Lightly press the side of the printer’s dust cover inwards.

Step 10: Lower the printer’s dust cover.

Caution: Don’t lower the printer’s dust cover if you are not pressing the sides inwards. Doing otherwise might get the printer or the dust cover damaged.

Note: Before you print or copy, you need to choose the correct paper type and paper size settings from your computer or printer’s control panel.
