HP Deskjet 3755 power button always blinks

[Rainbowxueming]

Hi Everyone, 

I don't know why my printer (Deskjet 3755) all of a sudden couldn't print. I press the power button with all the cables on and then the power button starts to blink for a long time and never print anything. I unplug everything and restart my laptop, but it is still the same. Anyone can help me with that?

Welcome to HP Forums. This is a great place to get support, find answers and tips.

I have gone through your Post and I would like to help.

Do you have any other lights on the printer other than the Power light?

Are you able to make Photocopies?

Let's start with a printer reset

(1) Turn the printer on, 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) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed
 

Based on the Mac OS version, check if you have any Firmware updates available for the printer.

Hi,

I tried twice, and the power button is still flashing (the wireless blue light is also flashing) and I couldn' print anything. And I really need to make it work ASAP so as to print my documents for tax return and assignments

Is there any store/technician hat I can go to? I think it might be more efficient if some specialist can take a look and find out what has gone wrong.

It looks like you were interacting with @KrazyToad, but he is out for the day & I'll be glad to help you out. 
As per the user guide available here, a blinking power button light indicates that the printer is processing a job. To cancel the job, press the Cancel button. If the power button light is blinking fast then that means the cartridge access door is open, close it. If the cartridge access door is closed and the light is blinking fast, the printer is in an error state that you can resolve by following the onscreen messages from the computer. If you do not see any onscreen messages, try printing a document to generate an onscreen message.

Hi 

I already checked the cartridge door, and it's closed. And there's no on-screen message when the power button is flashing. The blink of the power button actually is not fast. When I turn on it, it stays white light, but when I press "print" to print a document, it starts to blink as if it's processing the job. Actually, nothing has been printed out and I couldn't even hear any sound from the printer that it's processing a job. It will blink for a while and won't stop unless I press 'cancel' button. Then the power button goes back to normal - stay white color. No matter how I restart, it's still the same - couldn't print documents. 

Is there any HP store or center or technician that I can go to in person to figure this issue out?

Printing a self test page is a good way to isolate if the issue is related to hardware or software. Instructions on how to print a test page can be found here. If the printer is able to print a self test page. Then use the following steps to remove existing printer software and drivers from your Mac and install a compatible driver:

1.) Use the steps available here to update the software on Mac.

2.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

3.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.

4.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button  at the bottom of the list.

5.) Click the plus sign , click Add Printer or Scanner, click the printer name.

6.) Click the Use or Print Using menu, select the name of your printer in the pop-up menu. Then click Add.

7.) Try to print.

If the printer is not able to print a self test page then, I'm afraid the issue is hardware related and you may call HP Support to obtain all available service/replacement options. You may use the following steps to contact your regional HP Support:

1) Click on this link . 

2) Select your product type below.

3) Enter the serial of your device. 

4) Select the country from the drop-down. 

5) Select the chat or get phone number options based on your preferences. 

6) Fill the web-form and proceed further.

Hi 

I can print the test page but I still can't print after I follow your suggested steps. The printing work is always in the queue and shows 'Printing-waiting for job to complete'. And the color next to the printer is orange instead of green.

Now, what should I do?

How is the printer connected, USB or Wireless?

Could you create a new user account on your Mac and let me know if you are able to print from the new user account. Instructions on how to create a new user account can be found here.
