Sometimes it is the wrong power supply. I have seen it before. You need to verify that it is the power supply meant for a 3750. If you use a power supply from a 3200, this problem can occur.

Call for a replacement unit. The printer prints by heating up the paper in a tiny dot. If it is not heating up enough, the printing is very light.

Before returning the terminal simply check to ensure you have the paper inserted properly. Thermal paper will only print on one side. if inserted backwards and your printer runs hot then it is possible for the light print to "bleed" through the back lightly. If that is not the problem, then call in for warranty.

When this begins to occur it can be the roller mechanism inside the clamshell. If one side has a bushing that is going or is not getting firm pressure the paper, it will create issues for the printing mechanism. This is normally where I start.

Have you by any chance set the print properties to DRAFT? that will print a light copy to save ink and looks like what you describe. goto printer properties and select the correct mode or default.

Omni 3750 is only partially printing the recipts.


You either have bad paper or you printer head is going out. Firs, replace the paper. Thermal paper goes bad over time.

Replaced paper in Omni 3750, now it feeds but doesn't print


Make sure you are using thermal paper and it is feeding from the bottom of the roll. If not press down on the lid when the paper is printing sometmes the tension springs were defective.

The printer apear to be dead!


Buttons and lights on the printer Two buttons and three lights are located on the front of an HP Deskjet printer.
  • The lights tell when the printer is working or when it needs attention.
  • The buttons help control the printer.
Buttons and lights Purpose c00123886.jpg POWER button and light Push the POWER button to turn the printer off and on. When lit, the light shows that the printer is turned on. c00123889.jpg RESUME button and light The light blinks when there is a problem with paper. When the problem is corrected, press the button. c00123892.jpg Print cartridge light The light blinks when there is a problem with a print cartridge. When the problem is corrected and the top cover is closed, the light will stop blinking. Troubleshooting blinking printer lights Blinking lights Reason c00123895.jpg

All lights are off. The printer is off (asleep).

Press the POWER buttonc00123886.jpg to turn the printer on.

The printer should turn on automatically when a print job is sent to it. c00123898.jpg

The POWER (top) light is on. The printer is idle.

The printer is ready to print a document. c00123900.jpg

The POWER (top) light is blinking. The printer is busy printing.

Allow enough time to print. When a document has many fonts or graphics or uses complex color such as a color photo, it takes longer to begin printing. c00123902.jpg

The PRINT CARTRIDGE (bottom) light is blinking. Possible causes:

  • The front cover is open. Make sure the front cover is completely closed.
  • The print cartridge is missing. Make sure the print cartridge has been installed correctly.
  • The print cartridge is broken or incompatible. Lift the front cover, and wait for the print-cartridge cradle to slide out. Check the part numbers on the print cartridge:


Black: 51645A

Color: C1823D,

If the print cartridges are compatible and correctly installed, they may be defective. Try replacing the print cartridges.

If none of the above suggestions fix the problem, and, if the error message still occurs, it may be a hardware failure. Call the HP Customer Support Center.

The red attention indicator light and the toner indicator light are both flashing together


ON your driver check that the paper size is correct and this most commonly occurs when the incorrect paper size is selected. For example if you are printing to A4 and you have letter size installed in the machine then the system will cause an error or jam when there is nothing there.

Also within word or which ever program you are using on the document goto file and then down to page setup once in there check the paper size make sure it's correct for the paper in your machine also check the paper source. Once you have done this check the paper tray guides are correctly against the paper turn on and try printing and hopefully this will work.
