Photosmart 7510e - Paper not feeding automatically, Will feed Manually

I have the same thing - 3 year old machine. Clearly the take up roller is clean and comes down to the supply stock - but the rollers do not turn. They rotate freely when the arm is in "up" position - but that may be normal. The gears are tiny little plastic things and I can guess one is busted - impossible to see and hand to get in there. I will look for a repair center but failing that, I'll just tear the damned thing open and give it a shot. Likely, I throw this out and start out. HP is famous for this. I went through their forum and this problem is never resolved. I think I will try another brand. Too often the HP machines are cheap to buy, ink is pricey, and long term use is futile.

I spent full day trying to find service locations, schematics, sources for parts, or simply answers. I finally wrote Meg Whitman at HP and got a helpful response from a service office:

1. Parts not available

2. Schematic not available

3. Problem (mine at least)clearly mechanical - gear busted.

4. No solution - no repair - at least at practical costs.

5. HP gave me a deal on new species (Envy 7640) with similar features. Half price reconditioned machine, one year warrantee, shipped free. $80.

6. More or less, service rep agrees printers by HP are not expected to by repaired.

It is the old business model of cheap razor, pricey blades (ink.) Printer is a big razor and a lot of waste and mess in trash heap - but HP doesn't give a %#*@.

I will not buy their lines anymore - printers, PC, or whatever. If anyone wants a couple of new 564 ink cartridges (HP) unopened, write me and I'll mail.

I'm usually pretty handy but I gave up trying to fix this problem. However, I loved the cartridge cart on the 7510 (so easy to remove and clean) so I looked for other HP printers that used the same cartridges. Walmart had a sale on refurbished HP 5520. They were practically giving it away for around $50. Heck, the new cartridges alone were worth 20 to $25. I bought refillable cartridges and it has been running beautifully for the past 6 months.

HP SUCKS! Same 7510 crap! Cleaned all parts at least 6 times! What a waste! Cheap plastic gears! Pick up does not turn when it comes down on the paper! Cleaning is a big waste of time! I have been using HP printers for years and they only last 2 years if your lucky! Never again! Now that this one has crapped out like the rest have, it's time to start looking at different company's for a printer! HP you can kiss my Butt! Never again!

Hi George,

What better way to spend lockdown than to fix that printer.

I hope this helps and that you can see enough detail in the pics to see what’s going on.

Hi everyone. FYI, the repair I made in 2016 (see comments above) still works. I still use the printer. For those who have the same issue, it is worth a try!

I am having literally the exact same problem on my 7510 and came here looking for help. I've got it partially disassembled and hope to get the feeder assembly out but it looks like a pain in the @%^ to get to.

The rollers on the paper feeder turn but very weakly and I can hear crunching sounds but the exposed gears seem to be OK. I'll post more once I have done more of a thorough investigation.

Basically at this point it's fix it, or get a new printer so I have nothing to lose.

Hello, I have the same problem with mine (HP 7510).

Symptom: the feeder goes down on paper. It makes some noise, but the wheels barely rotate and do not push paper through to the second set of wheels. If I put my hand under the feeder to stop it from going down and then push the paper manually, the second set of gears catches the sheet and the printer works fine.

After inspection, I found out the culprit: all the gears within the feeder are working fine, but the first one, attached to the rotating axis, must be to old and it is not stuck onto the axis anymore. The axis turns fine, but it does not get the gear to rotate as soon as there is a slight resistance (which is the case when it has to push paper).

I do not know how to repair that. I may try to glue the gear on the axis, but my experience with this is not very good as the rotation is "brutal": it starts and stops violently, so the glue can only last a short time.

Would anyone have an idea? Do you think we can get spare parts?

It is the second HP printer I have where a small 2c plastic parts breaks after 2-3 years, which eventually causes the whole printer to be trashed. Honestly, that is a shame.

Hi Guys,

28th Jan 2018 - I have an HP Photosmart 7520 with the same small cog slipping problem. Glued it once but it only lasted a couple of weeks. So now I am trying a different approach. As the printer is basically scrap I am thinking there is no need to be gentle with the thing and as its vertually impossible to take apart with screw-drivers and tools. So lets look at it from a different angle. We need to gain access to the cog on its shaft to so that when glue is applied we can see how well it has stuck. My plan is to cut a hole in the base of the printer to gain access to the area around the drive shaft. Watch this space.

Steve - why should I dump the printer just because of one small cog!

29th Jan 2018 - So now I have cut a hole in the base of the printer to gain access to the cog that drives the paper tractor. Now I can see whats going on.

On close inspection of the cog I found that it has split so it will never clamp onto the splined area of the shaft so it will be totally reliant on the glue to get it to grip to the shaft.

What I have done now is to apply some epoxy glue to the shaft, sliding the cog over the glue and add more along the shaft after roughing it up to give the glue a better chance to stick. and because I have placed the printer on its side the glue will flow over the end of the cog and end up in the teeth. When the glue set I cut away the excess on the cog teeth but leaving as much there as possible.

I am now going to let the stuff set over night before I try to run the printer, but if that doesn't work at least now I have easy access to the area through the hole in the bottom of the printer where the paper sits.

I too had and repaired this nusence trouble with the HP Photosmart 7510 printer. Attached are pictures:

1. cut hole in bottom of printer below the "pickup roller gear set".

2. slide "slipping" gear off to side and clean with alchol.

3. apply epoxy to gear axis with long wooden q-tip (or similar tool), then reposition gear.

4. let dry and start printing.

Hope this helps.

I got the gears fixed but printer still does not work. It’s as if the unit does not detect that there is any paper in the printer to process.

I cut out a piece of bottom above the feeding arm, there i saw the gear is from his place, put printer with bottom up offcourse.

I made a bit of steel glue, put a bit in the place for the gear, shove it on the place, and put some glue also on the side of the gear and drive shaft.

After a night drying i put is al together after good cleaning inside from the sawing the bottom.

And............started a printer diagnostic page, 1 error display "not good powered off, it runs and calibrate, and then YES it picks a A4 and prints perfect.

This is the only easy repair for this problem, perfect, no new parts needed

See the Grey glue

Thanks for the tips

Figured it out!! Reach into the paper feed area from the front. Feel for the pick-up roller assembly (it has two rubber rollers on it). There is a small plastic piece on the bottom of the roller assembly that slides to the right (when facing the front). After sliding that piece to the right, the pick-up rollers are working fine again !!

Well it looks like we've all figured out this thing sucks.. I tore mine down to the bones but stopped once I was going to have to start disconnecting the tubes on the lower part of the cleaning trays under the ink cartridge holders and it got me no where closer to the inner part of the feeders other then an extra 1/2 to 1 inch of room but not in a very good way when your having to hold half of it, moral of the story don't screw with trying to pull it apart to get a better angle at the gear. I tried loctite and it literally lasted for about 15 prints so not much help there. What they should've done was had a square shaft on there or a double key pressed into the bar that way it had more grip instead of grinding out a hole in the gear. they wouldn't be throw away items if they put a little sense in lasting designs instead of "Hey it printed a page so it works, right?" HP's new model should be "Built to work, but not to last".

The only Solutions I can think of are

--drill a small hole directly threw the gear and rod and put a pin threw the hole and loctite it in place.

--move the gear to the side and clean off the rod where pieces of the gear still are and find a VERY good glue that bonds to plastic and metal and put it on and then slip the gear back on and glue the outside of the gear to the rod too (still looking for the glue but needs to be liquid).

--someone mentioned earlier about using a 2 part material to put on the sides to grind it and bond it but what might work instead is to move the gear over to the side and put that on the rod and pack it on the and rotate the rod so that is grabs the gear marks and essentially becomes a replacement gear, of your good enough it might just work .

--Else take the thing out back and blow it up...

The only positive detail I can add is that because HP is a publicly-held outfit, the senior folks can be found.

My complaint - by letter - NOT EMAIL - went to Meg Whitman who gets a lot of press and so far doesn't seem to have helped anyone.

My letter went to a special department which most big outfits have - I call it "The Crank Psycho Complaint Dept" where reasonable adult folks jump in to the fray to sidetrack the person with plastique strapped to his chest, standing in the lobby with a broken ink jet printer (for example.)

My dead machine stayed dead - but I got a replacement with numerous bells and whistles - for about 50% of retail. Not the answer that defines a mfr of integrity - but at least a stop gap. Meanwhile, I am reviewing other brands, ready to buy a replacement when this HP printer digests itself.

When a mfr competes in a commodity market, offers things which are not really unique, and sinks to fighting a battle of cost control and aggressive discount pricing, the war is lost. It just takes a while to notice. HP has been dead for a long time but nobody has held a mirror under its nose to check for breath.

Hi, I have the same problem. Can anyone put photoes how to fix this printer? Previous pictures are not available. Thanks for help.

The weakest part of this printer are the plastic gears, especially that one particular gear. It should have been made of steel. I had the same problem. I cut a piece of the bottom plate off to expose the gear. I used a dremel tool with a tiny saw blade attached but I suppose you can also use a multi-tool with a cutting blade. I immediately noticed the gear was cracked straight through to the shaft therefore slipping and making the gear useless. I cleaned the gear and the shaft with alcohol and used epoxy to fix the cracked gear and secure it to the shaft. I put a lot of epoxy on both sides of the gear to make sure it was well bonded. I also dabbed a little on the shaft where the gear seats. I let it dry for 24 hrs and then started using it . It's been working flawlessly since I repaired it and that was 2 years ago.

Great solution, my 7510 prints again, thanks for the older idea on this topic

I know what to repair. But never think off cutting the bottom. I did see a complete disambling for me but cutting and repair was done in 20 minuts.

Bison steel glue 2 component will never let the gear go.... hard as steel

A luck i find this site
