Black only prints on Print Quality Diagnostic report - Photosmart 6525

I have a Photosmart 6525 printer.  On the 2nd page of a 2 page print, black rapidly faded out.  Cartridge only weeks old and printer ink level check showed it as nearly full.  I ran the Clean Printhead option which printed out a Print Quality Diagnostic when it was done.  All of the informational text printed perfectly but nothing in the black grey-scale box or in the alignment.  Still won't print or copy black.  **bleep**?

The informational text on the print quality page is printed with color and black inks, so that if one or the other is not working the print will still be visible. 
I would suggest going through the troubleshooting steps in the document here.  Be sure to check the vents as described in that document. 
Is your printer still in warranty? You can check with HP's warranty tool here.

  • HP Photosmart 7510 - L:ooking at my Print Quality Diagnostic Reports - Why so many more "PHA Drops?"

    My Photosmart 7510 C311a indicates it has printed about 7500 pages since I purchased it in about November 2011.
    Tonight, after replacing the Cyan ink cartridge, I ran the cartridge alignment and then printed out the Print Quality Diagnostic Report.  As I was checking it out, I noticed the mention in 11, 12, 13, and 22 of the words:
    11.  PHA Installed:  01/24/2012
    12.  PHA TTOE Completed 1
    13.  PHA Hex ID: K: 3ff11948_5c3f230b, C: 00f11d60_5b421f06
    and on the line across the page for Item 22, with numbers under each color cartridge,
    (Cartridge Color)       Photo                  Magenta             Cyan                    Yellow                     Black
    22. PHA Drops          1493032000   4700387000   7245406000   51771850000   13001389000
    While these numbers are very large, I was curious as to how quickly the grew in the very short time (like five minutes) between the time I ran the first diag report and then aligned the heads and ran another diag report -- at the most it was five minutes and I printed nothing in between.  Then, after calculating the growth in each number, in about ten minutes, I ran another diag report and the numbers grew again.  For each color cartridge, over the three tests, with no more than ten minutes between tests and with nothing but the three reports printed, here are the three sets  of numbers  for "PHA Drops."
    Photo         1493032000        1494847000         1496485000
    Magenta    4700387000        4702380000         4704197000
    Cyan           7245406000        7247860000          7249779000
    Yellow        5177185000         5179178000         5180995000
    Black          13001389000      13008428000      13013963000
    Between the first and the second diag reports, the numbers for each cartridge increased by the following numbers:
    Photo           1,815,000
    Magenta      1,993,000
    Cyan             2,540,000
    Yellow          1,993,000
    Black            7,039,000
    I didn't bother to calculate the change in numbers between test 2 and test 3, but I suspect the numbers will be similar.
    My question is this:  What exactly is the definition of a "PHA Drop" and how does it fit into whatever the "PHA-related process" entails?
    I have read two or three "PHA Drop" related queries and answers on the HP Forums and the answers -- bluntly -- sound like the answer-maker either has no real idea what is involved - or - thinks nobody on the forum could understand the real answer.  Bad form..
    I don't think there is a 'conspiracy to deny' here and I don't even think the PHA Drop is something I must know about to sleep tonight -- but, it is an obvious and open part of the information that HP has seen fit to include in every Print Quality Diagnostic Report and one of the posted answers states that the whole PHA 'thing' is only used for "diagnostics." 
    Okay, diagnostics run by whom and when and where and for what purpose?  A really good, complete and accurate, fact-based answer might even help HP Users better understand the equipment we have spent good money to acquire and use.
    Answer please.
    Thanks

    PHA stands for Print Head Assembly.  This is the assembly of the color and black printheads and the electrical interconnect. 
    PHA drops are the individual ink droplets printed.  An individual drop is very small, on the order of 5 x 10 ^-12 liters for color, perhaps larger for black.   I would not be surprised to see 7 million black drops on a page.  At 600 dpi one square inch of paper would take 360,000 drops so 7 million drops would be about 20% coverage of the page if all the ink were used for printing  There will also be some ink used for servicing to keep the printhead clear.  The document here has information on how ink is used.
    The diagnostic page is useful in cases where there is a problem in printing and you call HP support.  They may have you print a diagnostic page and may ask for some of the particular lines to help diagnose the issue.  There are a large number of items in the diagnostic page that can be of interest to the support folks (or the engineers during development) but for the most part they are not useful for the end user.

  • "print quality diagnostic report"

    I have a HP Deskjet 3520 All-in-one printer and I just went to the "HP Deskjet 3520 series toolbox". Under the first tab (Device Services) is the button "Print Quality Diagnostics Page". I then clicked on that button and got the "Print Quality Diagnostic Report".
    However i can not find anything that tells me what all the diagnostics mean.
    attached is the document that I am talking about. 
    Questions:
    1.   The Magenta shows lines in the top of the lines on the top of the report but these go away at the bottom. Do I need to run a clean head cycle or seeing as that cartridge is low on ink just replace it?
    2.   In the bars of solid colors the light yellow (the bottom bar) has a white streak through it. Again I know it is low on ink. Is the issue there the ink level or does the head need cleaning?
    3.   Below those bars are numbered items about the printer but what does PHA mean? (Print Head Assembly?)
    4.   Number 22 in that list is PHA Drops. What does that mean?
    Does anyone know where I can go to get answers to these questions?
    Any and all help is appreciated.

    Hello RayGo75 ,
    Welcome to the HP Forums.
    I see that you would like some explanation on the Print quality diagnostic report.
    You stated that you attached a copy of the report that you would like reviewed but unfortunately, It is not listed on this thread.
    Please reattach it and I will be happy to go over it and explain any details that you need covered.

  • Hp color laserjet 2600n, very dim grayish film when printing black only

    For some reason, my hp color laserjet 2600n has started printing with a very dim grayish film over each page. I've had this printer for about a year, and it didn't do this at first. Does it no matter what program I print from. I'm sure it's a setting issue, but haven't been able to figure it out. Any ideas?
    And, when I select to print in black only, it still prints the color on web pages. Is there a way to print from only the black cartridge? These are the options in the printer dialogue box under color: print in grayscale, black only, 4-color. Under these settings are other options, edge control, half-tone and RGB color. I've tried each setting individually and still the gray film. The only other possibility I can see is under Print Options, it has draft quality or image quality. I've tried both and still the film.
    Have any ideas.

    1. take out all of the ink cartriges and look at the big black roller on the door for streaking, if streaking, clean with a lint free cloth dampened with windex (window cleaner) then close the door.
    2. let it run to initializing.
    3. open the door and look and the black roller on the door to see if you have streaking. If no streaking put one cartridge in and close the door and repeat the steps until you find what cartridge is causing the problem.
    I did this and found that my cyan was creating the lines on my paper. I cleaned the cyan roller with a Qtip and some rubbing alcohol and it works fine now, no more lines on the paper.
    Cheers

  • 6110 Will not print black only

    OBJECTIVE
      Print black only; color to print grayscale.
    PROBLEM
    Prints color images even when print black only is selected.
    Same for all programs: use mostly Office and IE.
    SYSTEM
    Op system: Vista Ultimate
    Driver: HPO4PG3L.GPD   1.3.2008
                 Last configured 8-6-07, default
    COMMAND SEQUENCE
    Alt F P
      Preferences
      Color
        Print grayscale
        Black cartridege only
    Have also tried:
      Preferences
      Advanced
        Doc options
          Advanced Printing options: disabled

    Hi,
    I would have thought that by selecting printing with the black cartridge only, via the driver, that only black would be used in printing.
    I am not 100% sure that this printer supports it but it may be possible to print with only the black cartridge installed. On printers where this is possible the unit works in single cartridge mode. 
    So to give it a try open the printer to access the cartridges and remove the colour cartridge.  Now close the printer again.  If the printer supports single cartridge operation you should get a message on your PC screen saying something like - Printing in reserve mode - Only the black cartridge is available for printing.
    As I say, this may or may not be possible with your printer but if it works then it will definitely not be printing with colour because you have removed it.
    The only other issue now is what to do with the colour cartridge when you remove it from the printer.  If it is just left out exposed to the air the ink in the nozzles will dry out and the nozzles will become blocked which will result in poor print quality when the colour cartridge is re-installed into the printer.  When the cartridges are in the printer and not printing they are held in a capping station that maintains the cartridges in good condition.  There is a little plastic item called a print cartridge protector which you should have if you have ever purchased a No. 58 cartridge for photo printing.  Normally the No. 56 print cartridge is stored in the print cartridge protector when the No. 58 cartridge is being used in the printer along with the No. 57 cartridge for printing photos.  If you have a print cartridge protector from previous No. 58 cartridge use then you could store the No. 57 cartridge in it while using the printer in black only mode.
    I hope that this helps

  • HP Photosmart 6520: Black ink is not printing evening after installing all new ink cartidges

    Good evening,
    Printer has been working great since I've bought it.  I replaced the black ink cartridge today because my daughter remarked that blank pages was printing ... no word doc.
    Tonight I tried to print and no black ink, neither from the Printer function nor the Copy function.  
    Just to make sure that this wasn't a bad black ink cartridge, I went out and bought and installed all the ink cartridges and still no black ink,.
    I have run the software - Clean Printheads, both steps, twice (after waiting an hour inbetween the first and second series.)
    I have verified that the in flows from the cartridge.
    I have verified that the vent hole on the cartridge is open.  
    The warranty ended on 12-31-2013. 
    The only time I see black ink (words) is when I print the PRINT QUALITY DIAGNOSTIC report.
    Printhead removal does not appear to be user available.  Any suggestions - other than buy a new one?
    Gunz

    Hello afcosta355,
    Welcome to the HP Support Forums! I see you are running into some print quality issues on your HP Photosmart 6520, you are unable to print in black ink after replacing the cartridge.
    I would like you to continue here: Printer Does Not Print Black Ink or Color Ink, or Prints Blank Pages, I understand you may have done some of these steps already but I need you to complete all steps in order to resolve the missing black issue you are experiencing.
    Please note: There are three printhead cleaning stages. Complete all three stages if necessary. If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last (third) cleaning stage to start the first stage of the cleaning process over again.
    If you are still unable to print in black ink, I suspect the issue may be the printer and not the cartridge. Please let me know which Country/Region you are in as well as the product Warranty status: HP Warranty Checker
    I hope to hear from you soon.

  • My unusual (?) printer issue -- Prints only partial lines when printing in black (part 2)

    I have been using my HP Officejet J4680 with my Win7 PC for several years and relatively problem-free -- until about six months ago.  
    My printing issue might be rather odd.  So odd, in fact, I’m not sure how to succinctly describe it.  I’m not too techie, but I will try….
    This printer will print some lines correctly, other lines print only partially, and some lines don’t print at all.
    This oddity happens ONLY when I print in black.  When changing the color of the text to any other color other than black the page does print correctly.
    Further, this issue seems to occur ONLY when printing certain things/files/formats.  For example, material from most websites will print correctly.  As will most .PDF files.  Printing files such as .txt, .doc, .wps, etc., seem to be the most problematic.
    Fixes I have tried include:
    Uninstalled and reinstalled printer
    Run HP’s diagnostic tools (including checking for any driver updates)
    Installed several new black ink cartridges
    Cleaned and re-aligned printer head
    Lastly, the “copy” feature continues to produce good results.  These problematic symptoms seem to occur only while using the “print” function.
    Short of relegating this printer to the trash, I’ve tried everything I can think of.  Help/ideas/suggestions appreciated.

  • Keep hp 6700 in good shape: automatic print quality diagnostic page every week?

    Hi all,
    I've recently bought the HP Officejet 6700 Premium, and I'm concerned about keeping it in good condition, since I had to replace my previous canon printer because of a stuck printhead (the photo black one, I didn't used it for a long time).
    Since I don't print much (but I'm using the ADF scanner a lot), and other family members prints sporadically, most of the time in black and white, I would like to setup an the printer to automatically print a diagnostic page every week to make sure everything is alright.
    Using eprint, IFTTT and google calendar I could automatically send a file to print (I already set up the printer to wake up a few minutes before the calendar event) with black and color bars (someone suggest to print the google homepage since it has many colors but uses little ink).
    Is there any chance I can directly print the print quality diagnostic page (so I can fully diagnose a problem if it occurs)?
    Thanks for the attention
    Cheers from Italy!

    Hey,
    To clarify for you and answer your new questions on the printers self maintenance.
    The maintenance cycle occurs randomly. It will occur after any power up, after print jobs(not every one) and any time it "think's" printhead health is poor. As mentioned above the printer to does have to be powered on for this to occur.
    You can if you'd like still print off the odd test page just to check, once a month would be adaquet.
    If you want to be saving power and are turning it off, then you would want it to be at least powering on and running the automated service that occurs weekly.
    I hope this clarifies everything for you. Thanks for your posts.

  • My f4180 prints in color eventhough I have it set to print in black only.

    I have been using my F4180 for a couple of years now. I have always used HP cartridges. For some reason, it will now only print in color. I installed a new black cartridge and the printer recognizes and that there is ink in the cartridge. When I remove the color cartridge it prints in black just fine, but as soon as I reinstall the color cartridge it prints only in color. I have never changed the printer preferences to anything but black only. I have run the diagnostic and it says everything is just fine, as long as I leave the color cartridge in. Any ideas on what to do?
    Another issue is that in Print Preview all I see is a blank page. It prints fine but shows absolutely nothing in print preview. That is new as well. Any ideas on that?
    Thank you.

    How to set my HP4502 to print from Mac in black ink only

    Hi @floraoverst,
    Welcome to the HP Support Forums! I see you would like to print in black ink only on your HP Envy 4502 with your Mac running the Mavericks 10.9 Operating system. Please follow the steps listed below:
    Printing with the Black Print Cartridge Only option
    Click File and then click Print.
    Make sure your printer is selected.
    Verify that the Preset option is set to Standard.
    In the Copies & Pages menu, select Select Paper Type / Quality.
    NOTE:If this option is not available, click ColorSync. Then click the down arrow beside Quartz Filter and change the setting from None to Black & White.
    Select the Paper tab.
    From the Color option menu, select Grayscale.
    Select the Color Options tab.
    Select the Black Print Cartridge Only option.
    If that option is not listed, then it is not available. The printer will print using only the black cartridge, however, printing with one cartridge will be slower than printing with both cartridges.
    NOTE:To save the setting, click the arrow next to Preset and select Save As. Save the Preset option as Black Cartridge Only and then click OK. Then, the next time you want to print with just the black cartridge, select the Black Cartridge Only Preset.    -Source

  • HP Deskjet All in ONe L7650 will not print black only --

     Started doing this with previously working black cartridge, updated software--prints, but blank page comes out when set to black ink only; prints other colors. 
    Changed black print cartridge and still will not print black.  Diagnostic page prints other colors.
    Printhead health shows good for all colors.

    What brand of printer cartridges (not printhead) did you use the last time you changed them?  I don't know if it was because one or both of my printer cartrdiges went dry, but I put new cartridges in (not printhead) and it improved somewhat--I kept trying to clean the printheads but it seemed to never get resolved.
    I refuse to have to buy new printheads.  I tried several cycles of "align printheads" "clean printheads" and never got a decent print out, but I did get to the point of all the colors printing although magenta printhead makes printing errors and so I never know what I am going to get with color anymore.  
    It seems to be at its worst when printing in "draft" but in normal or best (with more ink coming through) it seems better--the higher ink volume seems to cover some of the problems with the printheads.
    So, I am justing using it "as is" and not replacing the printheads--because it is a waste and yes, could almost get a new printer for this cost.
    I wish I had never gotten this All in One and just stuck with the old 970 csi and the old UMAX scanner, which was a better scanner, but thought I would "save some space" by getting this since it scans legal, which I needed.
    Just keep trying to reseat the printheads (also trying to reclean them, which seems to make it worse) and keep printing out those "tools" alignment and cleaning procedures.  
    But no help from HP.

  • Missing blank ink from Print Quality Diagnostic

    I've only recently bought my HP Photosmart 5520 (about a month old). I've only had to change the cartridges for the first time today - so I replaced all four intially supplied cartridges with the correct HP564 cartridges in Magenta, Cyan, Yellow and Black. Upon trying to print something for the first time, I noticed my black and white lecture slides (I'm a university student) seemed streaky. However, as my printer had been functioning as normal before this cartridge change I ignored it. Upon trying to print other documents involving black text however, whole lines went missing. I've printed 3 Print Quaity Diagnostics, the black ink column is either streaky or missing completly. The same goes for the Ink Delivery System Information report - all the blank ink is streaky. Cleaning the heads (Clean level 2) and aligning the cartridges has done nothing to improve it. This is a source of major stress two weeks before my final exams - if anyone has any idea what is wrong please, help. The other colours are perfect.

    The printer should be in warranty if you purchased it a month ago.  I would suggest you contact HP.  If you are in the US or Canada call 1-800-HPINVENt, elsewhere see the contact information here.
    As a temporary workaround you could tell the driver you are using photo paper, this will force the printer to use color ink even to print the black.  This is not a good long term solution but may at least allow you to print in a pinch.
