HP m1522nf AIO tickin' me off. Suggestions???

[redgtxdi]

So, it's old enough to consider tossing, but I'd rather not. The friggin' thing has been pissin' me off lately. As of yesterday when I turn it on, it does its boot sequence & once it gets to "initialize" it starts making a horrible sound while prepping the scanner (which I really don't need anyway, to be honest) and the sucker is making a grinding sound. Looking in the scan-glass the belts look fine, etc & nothing's happened to it, it just sounds awful & kicks up an error. Reboot, same problem.

So before I shop a new one or find a good used model of the same. Any suggestions?

TIA (P.S. For reference -----> http://h10025.www1.hp.com/ewfrf/wc/product?cc=us&lc=en&dlc=en&product=3442755 )

It might just need a couple drops of oil on the scanner rail or other moving mechanism. Whether it's worth disassembly to do that is up to you.

Personally I like Brother AIO for their ability to use inexpensive 3rd party carts or even cheaper $5 delivered DIY bulk toner, but note that if using DIY bulk toner on the original starter cartridge, it will need a "reset gear" to replace the starter cartridge low capacity gear, to get full capacity, a one time purchase.

Amazon has a pretty good price on a MFC8710DW for $275 right now. Of course there are less expensive models but this is closer to what you already have.

Thanks for the idea. In fact, I even thought about it looking at the rail & belt/pulleys yesterday. The belt & pulleys still look ok and I remembered having to lube an old dot matrix printer rail eons ago and it made me think.

I'll bring my nice screwdriver set to work tomorrow. That thing's gettin' screwed one way or another tomorrow!

Think I got it!!

It's this little mother....... "Mitsumi M35SP-9T Stepping Motor". (At least that's what it says on the side!)

http://www.amazon.com/Stepping-Motor-CM2320-M2727nf-M35SP-9T/dp/B008DXV3T8/ref=cm_cr_pr_pb_t

It drives a couple gears which transition to driving the belt which drives the scan element, scooting it along the bar. Everything else looks to be in good order & the motor smells of 4th of July. (It will works but makes horrendous noise & does not move the scanner well whatsoever).

At first I thought it was the gears themselves but as soon as I got a look underneath the motor, I noticed that all gears were in perfect shape as was the drive belt. Now, do I really want to buy a new motor & R & R this thing or would it just be nicer to get a whole new unit.

(sigh)

Open to suggestions other than the single lead I see on Amazon for this thing if anybody's got suggestions.

^ Might still be due to the rail needing lubed, though I'd also put a 1/2 drop of oil on both of the motor bearings. Can't advise about the motor, but I'd probably repair it if you can get the motor for under $20 delivered, and if you're in good shape otherwise meaning you're not just about out of toner in your last cartridge, drum's in good shape if separate from the cartridge, fuser still has a lot of life ahead of it.

Didn't think about oiling the motor. I'd assume those 2 holes on top of the motor are what that's for?? (It otherwise looks like a sealed motor)

Rail was slick as a whistle but I still lubed it anyway......it just didn't need it. Roller on the other side of the scanner was also free as a bird.

And gearing otherwise moves smoothly when I free-hand the scanner back & forth. Being that the motor doesn't smell good, I don't know if oiling would help it but I'd be willing to try.

?(shrug)?

^ No it isn't likely to have two holes for oiling it, though if you linked a picture of the exact motor, particularly the rear of it that might help.

The oil goes directly on the shaft, under the gear where it enters the housing and on the rear of the shaft if it has a hole there or the shaft itself is exposed. If neither the shaft is exposed and there is no hole there then the motor would have to be pulled apart, which on a motor that size is usually done by unbending a few places they bent the metal. If it is welded instead then I wouldn't bother unless you're a veteran at micro spot welds and have a suitable welder.

Again I'd need a good picture to be sure but two holes on the front are probably to hold the brushes out, away from the commutator when it is being assembled (or reassembled).

Here's about as god a pic I can find on the web. This appears to have a 7 suffix, but basically the same. I can't find top side pics but there's really nothing there to remove. Just 2 holes (vent?) in the top about 1/16 diameter.

 

[mindless1]

It's held together by those tiny indentations in the circumference, for example one is between the PCB and the label, another above the letter "I" in STEPPING on the label, etc.

You can easily enough put 1/2 a drop of oil on the shaft between the gear and top bronze bearing but those little indentations are so small that they could be difficult to bend back. I would just oil the top and rail then see if it was enough.

Mindless,

Thanks again for your help!! I sure as heck tried, but ya, there wasn't any prying those things up. In fact, I couldn't even fit a razor blade underneath them, much less a small screwdriver. And oiling the top (I oiled the bottom too & worked it like a swiss watch) didn't do it. Sooooo........I caved & ordered that motor from Amazon. I figure it's cheaper than a whole new unit & there ain't no 1522's for cheap anymore so for $30, I'll give it a shot.

I will definitely post results when I swap motors & fire her up.

Thanks again! :thumbsup:

^ Be sure to lube the rail too (if reasonably possible) as the extra drag on it could have been what did the motor in.

You can't really get a screwdriver under those tabs, you have to sort of grab the whole area with needle nose pliers that have the serrated teeth on them then brute force it apart by bending outwards, then to bend them back again during reassembly I gently use a hammer and chisel... I mean on different but similar motors.

 

[redgtxdi]

Yes, I definitely had lubed both, although the rail was still slick as snot! (no joke, felt like a silicone lube that sucker was so slippery). Still no joy. I think there might be something wrong in the motor that affects only one direction because as it's "initializing" it seems to move one way better than the other. The other just sounds horrible.

I'll probably bring some of my super-wazoo treadmill silicone lube to dress that rail to be absolutely sure.

Again, I'll update as soon as new motor arrives & is installed.

Oh and if the motor wasn't the prob, I'll be sure to record video of me shot-putting this thing off the roof of the building.

^ Wouldn't it still be useful as a printer? Adding a separate scanner seems cheaper than buying a whole new midrange AIO, especially since the scanners in them are nothing special.

And I'd love to if it would boot otherwise, but it won't. As part of the boot process it needs to cycle thru getting the scanner thru a distance before it'll get to menu start. Otherwise it gives you a prompt that tells you to "turn off/on and retry". (nice, eh?)

Cuz ya, I'd be fine w/ just using it as a printer....(what we use it for 90% of the time anyway). But without being able to even get to the menu to see if it could be done (i.e. omitting scan options or bypassing scanner self-test) I can't get there from here.

SUCCESS!!!!

So I ordered up the new motor. Got it last week & installed it yesterday! All works well!! I actually was frankensteining it a little bit w/ the glass off but I knew right away it would work cuz the stutter going 1 direction was gone. But without the glass on initialization, it doesn't know where to stop so I actually started skipping the belt & had to quickly shut off....(don't need to snap a belt right now, please God no!)

So put it all back together after fighting one corner a little bit (there's a magnet wrapped around the wires in the NW corner & had to tuck it away well before the corner would sit right but got 'er all dun & she's smooth as silk now!!

P.S. The amazon distributor was a company called "Laser Express". The motor is stated as being new, certainly looks it & performs as such. Shipping was quick & for $40 OTD, I can't complain!!

Thanks again for the feedback & suggestions! :thumbsup:
