20 Most Recent HP Photosmart C4280 Aio Printer - Page 4 Questions & Answers


Unfortunately, there is no repair manual, schematics, or diagram that relates or corresponds to this issue.

But try the below link, There are some images there that might point to the problem.


I think you will need to disassemble the whole printer, in order to openly see the space where the black plastic would fit into. The space for the black piece would be visible the moment the printer is disassemble.

So turn off the printer, disconnect it's power cord, pry off the body of the printer from side and back. Also, use the appropriate screw driver where necessary.

I hope you understand the above.

Good luck.

Open the cartridge access door, see where is the cartridge dock .. if its not stationed on the right hand side then try to move it with your hands back n forth

Close the door and it should work.

Lets assume it did not

The unplug the power cord from the back of the printer while its on.

Press and hold OK and CANCEL button at the same time

While holding them plug in the power cord, it should turn on and then release the buttons.

It should work

By the way also chek if there is any paper which is obstructing the carriage in moving freely

Your refilled hp 74 will not register as full after you do a refill.
You will have to remove some ink out of the ink cartridge.
There is a special clip that can be purchase to do this.
You could just leave the cartridge in overnight for the ink to reach the bottom.
The ink cartridge will then be able to print.

You better buy a new printer.Probably you have a problem in carriage unit on your printer.

If you have followed the manual, you've done your part right. If it is a genuine HP cartridge then most likely the chip on the cartridge is faulty.

just had to deal with this problem and it fixed the issues. while the printer is on, open the service door you use when changing the ink. when the ink goes to the right side of the printer, you will see something slide back and forth to the front and back of the printer..this is the printer head. close the door and turn the printer off. the ink will return to the left side of the printer. while the printer is off, reopen the service door. the printer head is free sliding, so reach in and pull it to the front. watch out, there may be lots of loose ink in there. use a windex type solution on a paper towel to wipe down the plastic flippers. i did this a couple of times because i got tons of ink off the first time. i don't know if the printer head comes out, but i didn't want to chance it, and it worked just fine this way. hope it helps.

Black printer ink in HP Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

To remove the jammed paper from the printer

* Use the tab key provided on the left side of the printer door
* Be carefull while removing the paper.

Have you removed the shipping tape from the print cartridge? It covers the print head on the cartridge to protect them so they won't leak ink.

HP Photosmart... | Answered on Nov 01, 2010

No but if you use third party (non-HP) products you will invalidate the warranty and potentially you may damage the printer. Having said that, many users can and do purchase cheaper non-HP consumables and claim that they produce output of comparable quality. In the end it's down to you to weigh up the risk offset against the potential cost savings. HP (or any other printer manufacturer) obviously want you to purchase their own branded consumables, so they're always going issue dire warnings about warranty violation and inferior quality issues from using third party products. One other thing to bear in mind, it tends to be just as cheap/expensive to replace a printer as it does to repair it!

Would you kindly rate my answer please if this has helped resolve the problem - thanks :)
