Question about HP Officejet 7130 All-In-One InkJet Printer

1 Answer

Loud Noise Hello, First, let me thank you for the excellent pictures and written instructions for disassembly of the 7130 unit. They made it very easy to disassemble and reassemble the unit. I took the unit all apart, including disassembly of the entire service station, cleaned all of the service station parts of residual ink, and reassembled the unit completely per your instructions. I did not have a 'dead' motor, so I did nothing with it except remove it so I could wash out the ink residue from the station compartments without getting water into themotor on on its attached circuit board. I reassembled the printer, but the rat-a-tat-tat noise is still there and the printer reacts as it did before taking it apart. The sound seems to be coming from the lower right side of the printer (the service station area as you look at the front panel). The noise is representative of a plastic gear rotating against another plastic gear that is stuck and the noise is quite loud. I did not see any gear teeth wear when I took all of them out for cleaning. I also now notice a sound (represents a very short squeak) that sounds like an RF signal, likely from either the motor, one of the circuit boards, or some other electronic component. I heard this sound before I took the printer apart, but only since this problem loud noise began a few days ago; I did not hear this sound before this problem started. My theory is that there is a sensor or circuit board component failure that does not allow a positioning sensor to work properly; either on the long skinney board attached to the service station itself or the rotational sensor attached to the back of the motor, consequently the print head wiping / sealing positioning motor runs through the 'stop' command position, thus causing the gears to clash creating the machine gun noise. If you have any experiences or thoughts about my theory or what might be the cause and how to correct it, I would appreciate your input. Please feel free to call me or give me your phone number so I can call you so we can converse about this; a much quicker way to talk through the problem / test solutions than E-mail. By the way, I am the GUEST or second person with the LOUD NOISE problem you responded to on FIXYA.COM Thank you in advance for your help Criag Draves 641-210-9695

    I have the exact same issue as HangMan's loud noise. Rat-a-tat-tat coming from the lower right - completely disables the printer. I do not see any obvious solution and am about ready to give up on this. Anyone with a solution???

My apologies for just now responding to this message; apparently my fixya mails have been getting caught by a filter and trashed without my seeing them.

I can think of a couple strong possibilities for this issue, and you're right; talking it through would be a good idea.

I will get in touch as you requested.

Excellent instructions. Maybe you could underline the bit about not tipping the...

If your printer prints like this:
87192f1.jpgThis is because the developer blade for the black toner needs to be cleaned. The developer blade meters the right amount of toner that is deposited onto the drum which ultimately end up on the paper to create the image. What happens is over time, as the printer is being used, toner starts to build up a film on to the developer blade. This film get thicker and thicker reducing the amount of toner from the developer. When this occurs, the image on the paper will look faint show vertical white streaks. This can occur on any or all of the four toner developers in the imaging unit. Below describes how you can clean the developer blade.
  1. Open front panel.
  2. Remove the imaging unit by pulling green tab.
  3. Cover the green imaging drum with a towel.
  4. Remove screw from the left arm, it is located on the top left of the drum.b931d8c.jpg
  5. Remove the waste toner tank.
  6. Remove screw on right side attached to the waste toner sump arm. 9cc6cc9.jpg
  7. Pull the sump arm to the right and upwards to dislodge it.
  8. Pull the left arm away from the developer section. The arm is recessed into the developer section and will require some force to unseat it.
  9. With both arms free, pull the drum back to separate the drum from the developers. Do this carefully, there is a spring that sits on top of the yellow developer that may fly off.
  10. The drum is connected to the developer assembly with some wires on the lower left side. Swing the drum to the left carefully to avoid damaging the wires.233e6b6.jpg
  11. With the drum out of the way, side each developer cartridge out for cleaning. Don’t tip the developer cartridge hole down, since this will allow toner to spill out.0b1b92d.jpg
  12. The developers are cleaned using the same process. Remove the 5 screws that hold the plate down. Two screws hold a z shaped plates, remove them with the screws.
  13. When the screws are removed, lift the plate up and flip it upside down to expose the developer blade.
  14. The bottom side of the plate is the developer blade. It is the part of the plate that touches the developer roller. The developer blade is a thin metal strip with a 90 degree bend. It is the outside corner of this bend is where the toner builds up preventing toner to reach the image on the paper. By using a cleaning tool such as a knife or one of the z shaped plates, very very gently scrape the developer blade from one side to the other. Then change the angle that you hold your tool to get the blade edge clean. You will need several passes with your tool to ensure that the entire edge of the blade is clean of toner. You will know when you are done when the blade edge gleams and you tool will glide freely as you move back and forth down the blade.b57c9e0.jpg
  15. Reassemble the plate/developer blade back to the developer cartridge. Reinstall the middle screw and the two back screws first. There is some foam at the ends of the rollers. Using a knife or toothpick, carefully move the foam in such a way that it does not get trapped between the developer blade and the roller. Once the foam is out of the way and the blade is seated, then replace the Z plates and screws.a1c9ca4.jpg
  16. Clean the other developer blades using the same process. Once all the developer cartridges are clean, reinstall the cartridges in to the developer assembly. Don’t forget to reinstall the spring on top of the yellow cartridge.
  17. Align the feet at the bottom of the drum to the holes on the developer assembly. Press the left arm back into it’s position on the developer assembly. This will require some force to reseat it.
  18. Reseat the right arm back into it position, then reinstall the screws back into the left and right arms. Reattach the waste toner tank and reinstall the imaging unit back into the printer, and close the front panel.
  19. Run a couple of test prints to see if the streaks are gone.
  20. If the streaks are still there, You could try cleaning the blades again, it could be that the blades were not cleaned enough.
  21. If the blades or drum are damaged in the cleaning process, then you will need to get a new imaging unit.

Remove both the ink cartridges from the All-In-One.
Unplug the power cord from the All-In-One as well as the power outlet.
Now move the carriage (carriage is the one which holds the cartridge) Too and Fro till you feel the carriage is moving smoothly.
Then insert the cartridges close the access door.
Plug the power cord directly to a wall outlet without surg protector.
Before connecting the power cord to the All-In-One press and hold the # and no 6 button and then insert the power cord, do not release the keys
until you see a message a reset (if the screen goes blank then release the keys and turn the power on)
Now try printing a test page or make a copy

If it still makes a loud noise and the message comes up as scanner failure, then either the scanner or the scanner machanisum is bad, you may have to replace the unit

Good Luck

Canon np 7130 drum installation

Hello joeboo123,
The fact that you had the foresight to ask the question leads me to believe you can do it.Your question was is it easy. Well, its one of those things that is easy to anyone who has done it before. My suggestion would be to order the drum/developer cartridge, instructions are enclosed. This device was designed to be to a large extent consumer serviceable,and the drum is one of the items. I have to admit it is more difficult than Canon seems to believe it is. However, if you take your time, you can do it. The drum unit is to a large degree protected from mild probing. So you can fart around a little as you try and as long as you dont force anything you will be ok. In my opinion you ,at a minimum will be able to purchase the drum without having to pay a 3rd party. And in the event you find that you can't install the drum or just plain feel uncomfortable, you can always call in the calvary. At least you will have purchased the drum without paying the copier dude (I AM ONE LOL ) and his company the additional mark-up on the item. Again, it is awkward to install the first time. Just take your time. When it falls into place you will grin like a set of high beams. I have been working on copiers for over 20 years, which means nothing. I mite have left a trail of disaster for 20 years for all you know. But I am being honest that I believe you can do it. Take care and good luck. ............spinal...

Not a easy gear to get to, entire side frame must be removed. I always just replace the whole left frame as pictured, but really you only need to replace gear pic at top, like I say not easy, take pics so you know how to reassemble it.

HP 7130 Random grinding noise resulting in a stall

Filka, You are most likely beginning to experience issues with service station function usually created by the buildup of ink which becomes gelled and gooey, resulting in sticking parts. Two primary points of trouble can be involved; one very easy to see and reach- the other requires a fair amount of disassembly but once inside the job is not hard.

First, right on the edge of the service station (the black box beneath the carriage when it's parked on the right) you will see a narrow white wedge-shaped piece. This is a retracting "wiper" which is supposed to slide forward when the carriage is parked, and to the back when the carriage is preparing to move. It has a small rubber tab at the front edge which wipes ink from a gold contact surface right in front of the wiper. I've yet to see one truly do well at keeping the surface free of ink, but it does keep it from building up. It is quite easy for this wiper to become "glued in place" by all of this ink. Start by raising the maintenance door, causing the carriage to move out to the center and the wiper to retract(if they will). You can then use a dampened paper towel or cotton swabs to clean the contact in front of the wiper, then gently pull forward on the top of the wiper to slide it forward over the cleaned surface. This will remove some of the ink on the rubber tab and begin letting you clean the wiper itself.

The second area of trouble is the service station itself. The sleds and tray are likely to be heavily coated and the only real way to clear them is to disassemble the case for access. You can use the following link to go to a step-by-step photo/instruction guide that will show you exactly what's involved-
