Normally we don’t repair Inkjet printers, just because of the simple fact that usually it just isn’t worth the trouble. Inkjet printers are cheap and easy to replace, but now and again a cliente will insist that it is worth a try. Today’s repair was a HP Deskjet 3055A printer that had a constant paper jam about a few centimeters from the feed start. It looked at lot like a paper feed problem and we thought that it might have been due to wear and tear from normal day to day use. So we first looked inside the printer without taking it apart, just to see if we could spot anything that would be jamming the paper feed, but nothing looked out of the ordinary. Then we proceeded to Clean the paper pick rollers just as explained in HP site and the youtube channel. But it still remained the same, so we proceeded with the disassembly.
First thing to do is to lift the top panel a bit and push it slightly from the front towards the back and it should slip right off.
Then use a Torx screw driver T10, and remove all 4 screws where indicated in the foto below.
Now lift the top carefully because there are two flat cables just below the left side, slightly behind the printers lcd, and you could damage them if not careful. So take a look at the foto to see there location. All you need to do is gently pull them out.
After the top is removed, you can go ahead and unscrew the logic board off and place it aside.
After that, remove the four screws on the paper feeder below, and then just slide it out to get a good inside view.
Well, in our case the cause of all the fuss, was this little guy show below… a simple little pin. This just goes to show that sometimes the solution to a such an unusual problem is pretty simple to fix, and it actually makes sense, because of the place that printers normally stand are prone to swallow little objects from time to time.
We did find some other objects inside of the printer, but they were all in places that didn’t yet cause any problems, but we will leave you with the fotos of all the objects found and a final test print page.
Thanks for reading.
