HP c7280 - Pump Motor Stalled Error

HP c7280 - Pump Motor Stalled Error by rjw (12/23/10 2:42 PM) reply + / -
My hp c7280 printer keeps getting a pump motor stalled error. Does anyone know how to help me go about fixing that.

I have already tried resetting the hardware through the system configuration menu and retrying to print a test page, but that does not work.

Many thanks.

I have tried everything I have read to try to get the printer working. Nothing has been successful.

- Have a C7280.

- Forget error code (sorry...) but it was one of those stated above. Probably the worst one (my karma). Followed HP procedure stated at the beginning of this forum post: http://www.fixyourownprinter.com/forums/printer/50063. I tried it about 10 times to try to resolve the issue, but to no avail every time... No amount of key sequencing, code clearing, resetting, unplugging, waiting and replugging did any good.

- All levels showed correctly in HP Solution Center. Yellow ink level was low.

--> Solution found: Replaced yellow cartridge but also, ENERGETICALLY removed and reinserted each and every of the 6 cartridges several times. ENERGETICALLY as in I've got nothing left to lose at the epitomy of frustration kinda jerking to and fro movement under the lid. Picture it...

After closing the lid, the printer did it's "initialization" sequence once more and it didn't sound any better than before: the now all too familiar grinding sound like "I didn't press the clutch enough and shoved the stick into gear anyway" started it off followed by the pulley humping belt tug of war... Usually THE CODE would appear not long after. BUT WAIT ! Whats's this ?! A new warning appeared: CLEAR PAPER JAM. There was none... Pressed Ok. And waited some more. The test was f***ing endless. But finally, it rolled to a stop. No more crash code. I printed a test page, a diagnostic page and a sample page. Everything works fine now.

I know it sounds too damned simple but, it worked for me: ENERGETIC CARTRIDGE REPLACEMENT. Who would of thought...

My sincerest thank you's to every one who participated here and the other forum mentioned above. My cheeriest hi-five to those for whom my solution would work and my most heartfelt sympathies to you who tried yet another solution - mine - only to have it also utterly fail...

I fixed mine in about 10 minutes.

1. Remove the left side white panel.

Use a T10 screw driver (star shaped).
Remove 1 screw on the back near the panel.
Remove 2 screws under the ink cover near the left edge.
Push down on the dark plastic tab and pull the top of the white panel.
The the back will release along the top edge, but the front will be stuck.
Pull up on the dark plastic near the front edge. This will release the off white panel.

2. Manually actuate the ink pump.

The ink pump has a belt running over a 1.25" (ish) gear near the front of the printer.
It is a peristalsis pump with 6 hoses running over it. Turn the large gear counter clockwise several times. This will free the pump.

3. Check the operation.

The motor should start the pump during the power up sequence.

4. Replace the cover.

Thank you so much for posting this solution, especially with the careful details on how to remove the cover. Thought my printer was a goner when I got another error message, this one faulting the pump.

The time estimate is correct, took me about ten minutes once I found the star screwdriver bit in my husband's drill kit.

I still get ink system failure messages if I leave the printer on for any length of time, but as long as I use it and shut it off right away it works fine.

Thank you so much for these instructions for fixing my printer. I was ready to buy another one when I found these instructions.

Followed your 10 minute fix and it worked. Don't have to buy a new printer, thank God.
