HP 300 MFP M375 Grinding Noise and Strange Copy Quality Issue

We are having a copy quality problem with one of these units... The machine will print bands across the page (not in direction of paper travel) of pretty much all 4 colors spaced out by 3 or 4 inches on most of the prints. If you print a config page, the band is just black and happens on about 90% of the pages. You might get one or two that don't exhibit the band but most do. On color prints, you will always get a band, mostly multiples, of the different colors across the page. Also, we have noticed a strange grinding noise coming from the lower front right side of the machine? We removed all of the toner cartridges and the turned the printer on and we are still getting the noise so I don't think the print cartridges are related although they are not OEM. We have replaced the transfer belt, color mis-registration sensor assy, and transfer roller and also replaced the black print cartridge for this issue with no luck. I have a new set of cartridges coming to me but I still don't think this is the culprit. Anyone else run across this issue? It's really strange..

Same engine as the CM2320 which means it has two motors on the right side and if one of them goes bad it will give the color bars across the paper. To test just remove the right side cover and swap the motors since they are the same and see if the problem changes.

HP DESKJET produces grinding noise and now it wont print.

Hello can you please help with ny hp deskjet. It started when I print, the printer produces grinding noise and it will print. But when I turned ON my printer it doesnt print anymore because these gear/part is already broken. May i know what is the name of this?? and is these replaceble?. Thank you for your response

Hi thegoy_doy,
Unfortunately, this is not a replaceable part. My best advice would be to replace the printer.

Grinding Noise and Frozen Macbook

Last night I was awoken out of a sound sleep by a loud grinding noise coming out of my MacBook. This was not a 'hum' or a 'buzz' this was a full nuclear invasion Alert! When I investigated, the Macbook was frozen. The screen was on but the keyboard and mouse were unresponsive. I did a hard reboot (what else was there) and it returned to its happy little self.
I'm worried that this is a failing harddrive. Anyone else have an experience like this? I have an appointment w/ the Genius Bar but I'm not really interested in four hours on the road to get their opinion if they can't do anything until the computer completely dies.
PS. There was NO kernel panic.

A couple of things to try...
1. Run the Disk Utility directly from the DVD. Verify and repair permissions and then verify the drive. See if you get any errors and report back.
2. Run the Apple hardware test, also from the DVD.
3. Reset the PRAM and the SMC. Apple has outlined how to do this on their site.
If none of these things show any errors, that doesn't mean it can't happen again. I'm starting to think these hard drives in the MacBooks are flimsy and bad updates don't help either.

Grinding noises and frequent jams in HP Photosmart 6520

A piece of paper tore in the printer the other day and required a bit of tugging to get both pieces out. Since then, the printer has made grinding noises as it prints and every 2nd or 3rd piece of paper jams. And ALL pieces of paper have a notch or small rip at the same point after going through the printer. I checked under the printer and it's at the spot where a small stick of plastic teeth contacts the paper. I think this piece isn't moving at the right time (I can tell it's on a spring), causing the paper to catch on it as it gets pulled up into the machine. The standard "Paper Jam" routine isn't helping. Anyone have advice for this kind of problem? BTW, the printer prints photos just fine. It's a problem with paper feeding out of the tray. I've also been having frequent network problems with this printer for about a month, but I assume those are unrelated...

Hi , and welcome to the HP Forums! I understand you're getting jams, alongside some grinding noises. I would like to help! I would recommend removing the ink cartridges from the printer, and perform a power reset. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar. I would also recommend the steps in the following documents: A 'Paper Jam' Error Displays on the HP Deskjet Ink Advantage 6520 e-All-in-One and HP Photosmart 6520 e-All-in-One Printer Series A 'Carriage Jam' Message Displays for HP Deskjet Ink Advantage 6520 e-All-in-One and HP Photosmart 6520 e-All-in-One Printer Series Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

Is Spotlight making those grinding noises and spinning beach balls?

Since newly installing Snow Leopard I am finding myself getting delays and if I persist in trying to do work it results in spinning beach balls. All the while I hear grinding noises.
I am guessing it is Spotlight trying to do its work. But I'd like to know for sure.
I am trying to use Activity Monitor but, as usual, am having little success as I have never figured out the best way to use it that gives me any useful info. For instance, I'd like to see what is most active (and likely causing the grinding and spinning). With %CPU selected everything moves so fast, and names of things are too arcane for me to understand. If spotlight is in there it's not clear to me.
For now, I am using the Spotlight privacy settings to stop it from touching any of my internal drives - so I can get some work done.
Is there a manual on-off control for Spotlight?

Allan. Grinding noises aside, did you write anything else in your reply? I see two horizontal lines with nothing on them.
*Installing SL was an indirect result of my having to trash two internal drives and install two new ones; reinstall an OS; then rebuilt my working computer and making Time Machine back ups. Along the way I opted to purchase and upgrade one to SL. I don't think the noises I described as grinding are bad drive. Somaybe they're not exactly "grinding." Perhaps "ticking."

HP D1600 making machine gun noise and poor print quality

Hello.
Whenever I turn on the printer it makes a horrendously loud clicking noise like a machine gun being fired. It sounds fine during printing but the print quality is very low and it looks smeared. after printing the clicking resumes.
I've checked to see if there's anything causing a jam but can't see anything. I've also cleaned the paper feed and the cartridges and aligned the cartridges but it's still the same.
Please help

Fan Noise and Application Speed/shutdown issues

Hey, I'm a new mac user, so I've d/led some programs and such and am also just getting acclimated to the mac after being a PC guy for 15 or so years. In this regard, bear with me.
Anyway, I bought the computer under the pretense that it would run smoother and be less buggy/virus-affected than a PC. And while I've certainly found no virus issues (I've had it 4 days), it seems to be a bit bug bitten. I do not know whether or not its a certain thing affecting it or multiple things, owing to my lack of mac knowledge, but I thought I'd see if anyone here had any thoughts.
I've had a relatively loud fan from the start - it is not loud all loud all the time and it does not even stay loud after it gets loud, but it seems to get loud quicker than say a healthy PC would. Additionally, I've had a couple of programs run slow/stutter - both Safari and a thing I D/Led from VersionTracker (which I had never heard of until diving into the mac world) called GraphicConverter (to sort photos/pictures). GraphicConverter has crashed once on me, and additionally the icon for the mouse seems to remain 'attached' to the design for the tool even when opening menus. With Safari, it additionally crashed once (I was running to leave and wanted to check e-mails and such but don't recall right now exactly what site I was on when it happened) and has problems with running slow or not opening webpages quickly after having acquired a decent sized cache. This, as a PC guy, would make sense to me if my computer had ~2gigs or less space, but this computers got about ~93gigs. All of these things, with a brand new computer, are concerns to me.
I guess an aside question would be is Safari the best graphics-intensive browser for mac? Beyond this, really if anyone has insight into whether or not these are problems which are common and/or have simple, common solutions or if they are things to take up with Apple, I'd appreciate it.
Thanks!

Hi NewMac, welcome to apple forums
The Macbook Pro has 2 fans that can get up to 6000 rpm, they can get pretty "loud" at times.
There are a few things you might find usefull to know from now on.
1. On your harddrive in the Applications folder go to the Utilities folder and find Disk Utility. Once opened select your drive on the left and click "verify permissions". Since i'm dutch i lack the vocabulary to explain what this does but it keeps your system in overall good shape if you do this occasionally If it finds and displays a list with "permissions are... but should be...." let it finish and then click "repair permissions". This can solve simple issues with applications and preferences making apps run smoother.
2. Onyx, a maintenance app recomended for all OS X users, you can find it and read what it does here:
http://www.titanium.free.fr/pgs2/english/onyx.html
3. Monitor your mac, i find this is easiest to do with the widget iStat Pro.
You can keep an eye on memory use, computer temperature, fan speeds etc.
Download for free here:
http://www.apple.com/downloads/dashboard/status/istatpro.html
After 15 years of PC you will need some time adjusting and getting used to things but once you get the hang of it you will be the happy camper u were hoping to become when you purchased your mac
Keep an eye on this forum, you can learn alot and ask whatever you want to know.
I would also like to know;
How much RAM does your MBP have ?

SharePoint 2010 Manage content and structure copy operation issue

Hi,
I am trying to copy a subsite from location A to B in the same site collection using the copy operation of Manage content and structure. Site is getting copied but default.aspx page is not getting copied to the destination. I tried copying the default.aspx
page directly using copy operation but that too is not working. There is no error thrown but the page is not coming up in the pages library of destination site.
As a workaround, i copied the page using SharePoint designer but i am looking for a solution to this issue.
Thanks in advance
Ajit

Hi Ajit,
According to your description, my understanding is that you could not copy default.aspx page using Manage Content and Structure.
I did a test about this issue, and found the followings:
1.When I checked out the publishing page, then copied the site to other location at the same site sollection with Manage Content and Structure, the page was not copied.
2.When I checked in the page without publishing, and copied the page as the step1, the page also was not copied.
3.I published the page, then copied it, the page could be copied.
So , for resolving your issue, please check the default.aspx page, make sure that the page is published.
I hope this helps.
Thanks,
Wendy

Help with Touch photo and movie copy/paste issues

I recently moved all of my photos and movies from my Touch to a USB drive, and now I want to put them back but the Touch won't let me - how do I replace them?? My ultimate destination for the files is the Cloud, which I've just loaded.

It sounds like the poster tried to paste the photos into the DCIM folder in My Computer since that is how you can get photos taken by or saved to the iPod into your computer. However the reverse does not work for moving photos from computer to iPod.

Grinding noise when my HP LaserJet Pro 400 color MFP M475 calibrates

When my HP LaserJet Pro 400 color MFP M475 recalibrates, I get a grinding or gear slipping noise. Any idea how to fix it or what to look for?
This question was solved.
View Solution.

Noise issues are difficult to troubleshoot remotely and they could easily misguide even when we are close to the device.
Please do confirm if the noise is a grinding noise or squeky/humming noise.
As you have mentioned that it happens only while calibrating, hence I would suggest you to re-check & validate your toner cartridges. One of the toner cartrdige may be defective and causing this issue.
If not the toner cartridge then it would be one of the printer hardware component which is in question, hence an HP tech. might need to perform physical inspection of the device and the error condition.

So I have a 1.5 year old Macbook Pro (Early 2011) and since last week, it has been making a crackling noise that has escalated to a grinding noise. I went to Genius - they told me my HD was fine, but they could do nothing about the noise. I'm super upset

I have a Macbook Pro that I bought new in August of 2011. It's been wonderful up until now. Last week, I was watching a lot of Netflix for a day, but then it began making a tiny crackling noise when I started my computer. It wasn't really bothersome, but then it's escalated into a grinding noise. A loud grinding noise. I haven't been watching Netflix and barely use any of my applications. My RPMs vary when I'm idle and can go up to 5000. Sometimes, it falls to as low as 1600.
I went to the Genius Bar today and the technician did two diagnostics to test the HD and the parts as a whole. Everything was fine. I was like, ***. Anyways, I asked if there could be anything done for the fans because I was willing to pay (I'm out of warranty). But he said they couldn't DO ANYTHING. That I would have to deal with the annoying noise. I called up Apple and told them what happened and she said that there was nothing else that could be done.
I am so ****** because I did pay good money for this product and I expect to have the option to repair, ESPECIALLY since I'm willing to pay for the repair. Can anyone tell me what to do? Did anyone ever have this problem?

I would guess the fan is the cause of the noise. Suggest you take a look at it.

My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it. It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open.

My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it. It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open. I have read that it may have to do with my fan or HD. I am under apple care for a good amount of time but am wondering if this is a mjor issue. I would not be able to get to an apple care center in the near future due to being at school. Should I be worried or will it last by the time I am home in 2 months.

Sounds like the disk in your MBP is accessing data on wake up
If you are still concerned you can take it into the Apple Store where they can hear it to be sure

Strange noise and flashing lights -- can this be battery/power-related?

I have had two occurrences of a very strange sound and never-before-seen flashing of a light on my TiBook. Here is what happened:
I recently got a new battery (a NewerTech Extend 4800) for my 3 year-old PowerBook. I carefully followed the directions that came with the battery and installed it, then plugged in the power adapter to charge it up. I then started the computer so I could see the battery’s progress. Upon start-up, a “whooo” sort of sound came out of the computer for a few moments and the little sleep indicator light flashed several times (as did the apple light on the back of the computer lid). Nothing appeared to be out of order and the computer started normally otherwise. I was able to monitor the battery’s progress and since everything seemed to work normally and no one I talked to seemed to think I’d damaged anything, I just used the computer normally for the next two weeks with no problems.
Then last night the computer just shut down all by itself – I did not put it to sleep and it is not set to go to sleep on its own (my power saving setting is only set to dim the screen), nor did I click “shut down.” I thought perhaps somehow the power cord had not been attached and the battery had run down, although the new battery has been warning me properly when the battery is getting low, so that doesn’t make sense. It would not wake, so I restarted it. Upon restart, the same noise and flashing light situation occurred again.
I called the company that sold me the battery and the tech guy’s suggestion there was to reset the PMU and he gave me an Apple article to instruct me on how to do that. I have done that, but there is no evidence that that has solved whatever the issue was. I am hoping that someone can identify the sound and lights pattern and advise me as to whether it is some more serious issue, or if it’s nothing to worry about. It has been suggested to me that it is possibly a power adaptor issue, but since I’ve run down and recharged the battery without incident several times in between the two occurrences, that doesn’t seem logical either. Is there a known signal a computer makes when there is some power/charging issue?
Thanks for any help you have or for at least posting if you have had a similar experience. So far, no one I’ve talked to has ever heard of this before.

Hi ChloeB,
Your description of the "moaning" sounds at startup sounds like something I'm dealing with. I came across the following post by EWW in the "My Powerbook Won't Start Up". I recommend the link and wish to specifically credit EWW with the posting, as I found it helpful. The URL is

Hi, limberlingo, and welcome to Apple Discussions.
Power On Self-Test Beep Definition - Part 2 (Oct. 1999 and later Macs)
http://docs.info.apple.com/article.html?artnum=58442
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
Your Powerbook is not detecting any good RAM at startup. This may indicate that your RAM (all of it — do you have one module or two installed?) has gone bad, or that it isn't seated properly. The first thing to try is reseating it: remove the module(s) and then reinsert it(them). Then try starting up again. If that doesn't do the trick, and you have only one RAM module, it's probably bad and will have to be replaced. A single RAM module having intermittent problems before failing completely (as it apparently has now) would account for all your problems.
If you have two modules, it's much less likely that both of them have failed or loosened in their slots simultaneously. Post back with results of your testing.

Strange noise and corrupted files and trouble fixing

hi. forgive me if someone's answered this already, but my eyes are bleeding reading through all the comments without finding a fitting answer. my ibook g3 dual usb has been great all these years. every once in a while i get the "unable to mount" question mark folder at startup and have been able to fix it using the disk utility first aid stuff that came with my computer. but i've also had trouble in the last few years with corrupted files paralyzing my computer anywhere from a few seconds to hours till i have to force shut down. when my computer comes upon a corrupted file it starts making this slight whiny grinding noise that happens as a series of noises - like eeeer eeer eeer eeer eeer - over and over. it immediately stalls all functions of the desktop/computer.
this last time, it happened while downloading a .pdf. unfortunately, after force shutting down, i got the question mark folder when i started back up and none of the utilities or norton disk doctor have been able to fix it. i tried running the hard disk testing utilities and disks, and it keeps saying the hard drive is fine. but whenever i run disk recovery with norton i suspect it comes upon corrupted files and starts with the grinding noise. i'm trying not to completely reinitialize the hard disk until i know i've tried everything. i just want to recover a few things, but i don't know how to isolate the corrupt files to trash.
under the repair function of the disk first aid, it says theres some kind of pdef problem or something, and that it cannot repair. DOES ANYONE HAVE ANY IDEA WHAT I SHOULD DO!!!! P L E A S E. i feel like i've tried everything, including the custom loading of softwar install....
thanks

Hi, and welcome to Apple Discussions.
The iBook would have come with the first version of OS X (likely OS X 10.0.3) installed on it. Using Norton DiskDoctor on any hard drive that has an OS X volume on it can actually cause hard drive corruption. DiskDoctor also reports the OS X files as "errors," so any "errors" it reports are not to be believed (although, as I said, using it can actually create corruption).
Could you please report the exact message you get when trying to repair the hard drive using Disk First Aid from the Install CD?
You may want to try a command-line method called "fsck" (for "file system check") to attempt to repair the hard drive. To use fsck, you have to run it from the command line. Unlike using your trackpad to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. To use fsck:
1. Start up your computer in _single-user mode_ to reach the command line.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it will display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
Your computer should start up normally and allow you to log in.
(This information is from the Apple Knowledge Base article entitled Resolve startup issues and perform disk maintenance with Disk Utility and fsck.)

Macbook strange noise and 3hr battery life

Hi,
My new macbook (before-june09 model) is making a strange DVD Drive noise when I turnit on, restart and wake from sleep. It also gives me only 3hrs of battery life.
I recently exchange my 2.5GHz macbook with NO noise and 5 hrs of life because I wanted to upgrade for this 2.66GHz, 350 GB, 4MB RAM when the price dropped due to the new models.
Now I'm starting to regret,is anybody having the same problem, or I just got a bad one.
Thanks

This is the temp on my uni 08 vintage after adding a 256GB Crucial M4. That's right, 150 degrees Fahrenheit when measuring with a meat thermometer just above where the SSD resides in the chassis. The battery lasts about 38 seconds when I take it off power. .... I'll try the 0309 firmware to see if that helps.
