    My HP L7680 Printer does not detect magenta or cyan ink in the printer. It does detect it in the printhead but not the printer.

    Note this is different from not detecting the magenta or cyan cartridges, it does detect those. Its just on the EWS (embedded web server) "Ink Supplies" page it reads under "Printhead Status":

    Refilled Supply

    Detected in Printhead?
    Black Yes, Yellow Yes, Magenta Yes, Cyan Yes
    Detected in Printer?
    Black Yes, Yellow Yes, Magenta No, Cyan No

    This is causing the printer to check itself after nearly every print and it does not usually print the magenta or cyan ink right.

    I am pretty handy and would like to try and fix it myself, however I need to know what sensor or part to replace. If someone can help me please let me know. I would be very much obliged!

    Cheers,
    Karl

    I have tried multiple cartridges and printheads to no avail. The EWS printhead status page reads the same each time. These cartridges and printheads do work perfectly in my L7590. This leads me to believe strongly that it is a part on the printer itself.

    I would like to take apart the printer and replace/ what I need to on it. If someone has experience repairing these please let me know what I need to look for.

  • Augustulus May 08, 2009

    Emmissionwiz:

    If it did not detect M/C ink in the printhead then I would think this is the
    right way to go, but it does. It says it does not detect it in the
    printer. This is unless the printhead contact is the part that senses it in both the printhead and the printer. Have you repaired these before and you know this is the case or is this just an educated guess?



  • Augustulus May 08, 2009

    I have tried different cartridges that work on another machine just fine.

    I opened up the machine and didn't find any problems with the connector ribbon on the printheads. Have you fixed these before?



  • Augustulus May 09, 2009

    Thanks for trying. I tested every lead on the printhead ribbon- all are conductive.

  • Augustulus May 09, 2009

    Thanks for trying. I tested every lead on the printhead ribbon- all are conductive.

  • Augustulus May 09, 2009

    yes this much I know- just need to know where to look. Thanks again.

  • Augustulus May 09, 2009

    Emmissionwiz: I want to fix it- I don't believe it is on the main board.

    No one here knows where it takes the reading of whether the ink is detected in the printer or not. This is where I want to start looking then work backward from there. No offense if you haven't taken apart and fixed several of these then please don't respond.

  • Augustulus May 09, 2009

    No offense- if you haven't taken apart and fixed several of these please don't respond. Sorry just don't want to waste either of our time.

  • Augustulus May 09, 2009

    Already done all this- again if you haven't taken apart and repaired several of these please don't answer- you will be just grasping at straws.

  • Augustulus May 09, 2009

    You didn't pay attention- if you haven't taken one of these apart don't answer! Its that simple. I have been through all of these basic banal solutions. Its an internal issue.

  • Augustulus May 09, 2009

    I have tried multiple printheads that have worked perfectly in my other printer so its not that. You obviously didn't read the whole question or comments because I clearly have said this. Neither did the others that have answered. I have been professional enough, when people do not read the details and waste time like you have done I need to start being vigilant. I consider it unprofessional to throw out answers without reading the details.

  • Augustulus May 09, 2009

    The embedded web server is not computer dependent. It will display the same errors no matter what computer connects to it.

Hi,

Sorry for all the confusion, but for us "Experts" we can only see one side of the convo, yours.

I can tell you're getting frustrated and will do my best to alleviate that for you.

If it makes you feel a bit at ease I have an L7590 sitting 3 feet to my left. and have owned several in the series personally as well as supporting them in several of my customers businesses.

Although I am only fully certified on HP laser not ink systems, I have worked on these models with great success in the past.

One problem I have not seen you respond to yet which may be a part of the issue. Clued in by the intermittent ink getting to your heads but not always continous is that you may not have a good seal, or good flow between the head and the cartridge.

This can happen for several reasons:

1. Airlock in the line. This can limit or even stop flow entirely without setting off any sensors. as there are none in the lines. Like a brake line in a car, this series requires pressure feed. if there is air anywhere in the cartridge or line the bag system in the cartridge cannot possibly provide enough pressure to force a steady flow of ink.

This being said it is unlikely the air is in the cartridge as you state it works in the other printer. To be sure you can set the cartridge bottom(port end) up for 3-4 minutes and look for any bubbles in the primer button or port. if you see any at all, grab a 8-10 gauge filling needle, depress the plunger and slide it 3mm into the ink port. pump the primer 4 times, pulling up gingerly on the plunger after each pump. By the last pump you should only see ink, no gush of air come up, if not try one additional pump at a time unitl you don't see air spraying up.


If/when the cartridges are primed, re-insert them and open your sulution center, click on settings(sorry if this sounds simplistic, but I'd rather over simplify than miss a single step), then printer settings and printer toolbox. Click on the services tab, then click on Calibrate Linefeed.

Even if you have tried this already, without ensuring the cartridges are primed it's hard to be sure you can force any air that might be in the cartridge through.

Once you have done that, run your head calibration one last time, assuming the linefeed calibration forced the air into the head the calibration should work it out.


2. There may simply be a faulty or dirty seal when you installed the new cartridges. if you give the input port on the effected heads, and the ink port on the effected cartridges a quick wipedown with a q-tip and methyl or glycol alcohol(rubbing alcohol(50% or better) will do), as well as any contact ports(working from memory) if you see any pigment coming up keep scrubbing, the last time I had to do this it took 45 mins(on my officejet 1200), if any of the seals have more than 1mm of dried pigment on them it can corrupt the seal.

3. Bad airlock in the head, it will still be wet inside in most cases so the sensors reads ok but airpressurizes and just trickles out a dribble of ink. If your model is the one I think you should be able to remove the head and cartridge, hold them somewhere ink safe and insert the feed from the head into the cartridge. then pump the primer a few times(suggest working behind a shield) and force ink down into the cartridge and the air up in cycle. pin in, pump once, wait ten second then pin out.... look out for the spray, pigment dyes stain almost as bad as tattoos.

If it's the opposite head design(with hose in between) use the priming method to put three-four pump into the syringe and then repeat above steps inserting the syringe into the head.



Shoudl these steps not work and if it is the model with a small hose in between the cartridge and the head you also need to prime the hose(out of printer) then replace it into the printer and hook it to the head.


Hopefully even if this doesn't solve the problem it will at least restore your confidence that there are "Experts" available on FixYa at all hours and feel free to reply back in the next hour or so as I will be monitoring this post until I'm done for the day

Most common reasons:

1. Didn't remove protective tape on cartridge.
2. Didn't properly seat cartridge.
3. Contacts on carriage need to be cleaned.

If it's 3, sometimes you can clean them by cleaning the contacts on the old "empty" cartridges, then installing/removing them a few times. The time I had to do this, I used a pre-moistened eyeglass cleaning sheet, and allowed the cleaned cartridge to dry before doing the install/remove cycle.
What's probably happening is there is excess ink on caked on to the contacts on the carriage (I think that's what they're called). They're pretty easy to clean and the cleaning process takes about a minute. Just remove whatever cartridges are in the printer, take a cloth that will leave a minimal amount of lint, and wipe at the dark spongey contacts located just below where the cartridges would sit ( they should be right around the cartridges' spot). When the caked on ink is removed and all you are wiping at is the sponge, insert the new cartridge and the printer should work.


if this doesnt..... then its definitely ur sensor problem...... and u might have to replace it.....
thank you hope this was helpful have a nice day

Hello augustulus,
a possible reason for these problem is that either the print cartridge or the print carriage contacts need cleaning, or a re-manufactured or refilled ink cartridge is being used.
Follow the steps below to determine why the problem is occurring.


Step one: Checking the print cartridges and cleaning the cartridge contacts
Even if the cartridge is new, follow the steps below to clean the print cartridge contacts. Print cartridges have a substance on the contacts to keep them from corroding during storage that may cause poor electrical contact between the print carriage and the print cartridge.

1.
Verify that your printer is turned on.
NOTE: If your printer is not turned on, you will not be able to remove the print cartridges.
2.
Open the unit to access the print cartridges.
3.
After the print carriage (the part that holds the print cartridges) stops moving, unplug the power cord without turning off the unit using the power button. If you turn the unit off the print cartridges will be capped to prevent them from drying out and you will not be able to remove them. You must unplug the power cord to prevent the print carriage from moving.
4.
Remove the print cartridges that is troubling you.
5.
Verify that the part number on the cartridge is the correct part number for the unit.
6.
Using a cotton swab or lint free cloth (like a coffee filter) lightly moistened with distilled, filtered, or bottled water, clean the electrical contacts of the cartridge(the shiny copper face).


NOTE: When printers like your own is used frequently for black and white printing but infrequently for color printing (for example, an all-in-one that is used primarily as a fax machine), the color cartridge will still eventually fail and need to be replaced. The pins in the print carriage can cause dents on the contact points of the color cartridge over time.
7.
Wipe the contacts on the printer's body with a dry, cotton cloth, as shown, to dry the contacts and finish cleaning.

8.
Reinsert the cartridges and lock them in place.
9.
Close the top cover or access door and plug in the power cord.
10.
If the error continues, repeat these steps. If further cleaning fails to clear the error, proceed to the next step

"Step two: Cleaning the print carriage contacts" below.

Have the following materials available to clean the print carriage contacts:

*
Cotton swabs or any soft material that will not come apart or leave fibers.
*
Distilled, filtered, or bottled water (tap water may contain contaminants that can damage the print cartridges)
CAUTION: Be careful not to get ink on hands or clothing.

Do the follow to clean the cartridge contacts inside the product:

1.
If the unit is off, turn it on.
2.
Open the unit to access the print cartridges.
3.
After the print carriage stops moving, unplug the power cord. Do not turn the unit off before unplugging the power cord.
4.
Remove the print cartridges that are not working fine.
5.
Using a cotton swab or cloth lightly moistened with distilled, filtered, or bottled water, clean the electrical contacts of the print carriage.

6.
lower the latches.

7.
Wait five minutes for the contacts to dry and then plug in the power cord. The unit will begin to reinitialize. Wait until the process is complete before proceeding.
8.
Reinsert the print cartridges when prompted and then close the top cover or access door.
9.
If the message recurs, replace the print cartridge indicated by the message.
If you are using refilled or remanufactured cartridges or non-HP cartridges, replace them with new HP cartridges.
10.
If the problem still exists, replace both print cartridges. Since the cartridges are electronically connected through the printed circuit board, the cartridge not indicated in the message might be the causing the failure.
Cheers!

Please remove all the cartridges and the print head
Look inside the machine to see if there is any ink build up preventing the transfer of ink
If there is clean it
If not check the nozzles and clean each individually
Let me know if this does not help so that I can continue to troubleshoot with you

Sir this is a very common problem today as we dont use much of color in day to day life on the other hand the print head is a sensitive end that get ruptured very easily so options are either to replace the print head or try cleaning the print head but before trying all these loose all static from printer and system as well as check the colour level and settings

Hi, the magenta ink won't work on my printer hp office jet pro k8600. I have replaced it with a new one and even though is shows that it's full on the ink levels it won't print it at all, I have tried all...


Materials needed: New empty syringe (big one) Gloves (to protect your hands fromink) Alcohol Paper tissue (to clean the excessink) Empty Plastic bottle (Here you putthe ink from the syringe) Important: Ensure that you have put new Magentaink cartridge to HP K8600. Ensure that the printhead arerecognized by the printer or no light alarms. Instruction: Press the Power button to turn onthe printer. Test print in microsoft excel with4 color black/yellow and cyan/magenta. If magenta only is missing means youhave clogged problem from the host. Wear your globes, prepare thematerials needed. Open the top cover. Press and hold the Resume buttonuntil the carriage moves to the left. CAUTION: Be careful not to proceed until the carriage is on the left sideof the printer. If the carriage does not move to the left automatically, turnthe printer off and back on and then try holding down the Resume button again.The printhead can be damaged if the carriage is not all the way to the left forinstallation. Lift the printhead latch. Lift the handle of a printhead anduse it to pull the printhead magenta/cyan out of its slot. Put printhead in thepaper tissue upward. Your printer are still ON becarefull not to touch the flex copper circuit. Get your syringe, use this to pullthe ink from the nozzle cap ( see link picture) After the done the syringe method,Insert the printhead magenta/cyan into its color-coded slot. Press down firmly on the printheaduntil it snaps into place. Pull the printhead latch all theway forward, and then press down until the latch engages. Close the cover. The printer should align theprintheads automatically in a few minutes, printing an alignment page. Print a test with magenta coloronly, If it does not print, try to change the Printhead. This is the only solution I foundin my HP k8600 printing problem.christan_11_1.jpg

Printhead problem


Most likely your right but you can use the diagnostic test tool which is free from HP. This is the second one I have had and the first one was the print head burned out, however the guy was using after market ink and thats what caused it to short out the head. heres the site thats for free.

The error states that you are using non-HP cartridges for all colours. If black prints fine then you should replace the colour cartridges with genuine HP colour carts. You should be able to get a refund on the refills since they clearly do not work as intended.

A blank page when coping or printing in black. New black & yellow ink installed. Cleaned print heads, run all the diagnostics, but no black shows up. Cyan, magenta & yellow print, but no black.


As with all of the solutions I've provided on this and the other HP88 printers, the problem is that the black printhead has become clogged due to the conditions the printer is kept in.

For some reason the pigment black ink in the HP88 printhead is particularly prone to clogging when used in hot, dry conditions where there is air conditioning or similar...

The only solution I have found to date is to replace the black ink with a dyebase alternative and use that with a new printhead. Finding this solution took me about 14 printheads and a lot of head scratching so it wasn't easy...

Finding a dyebase alternative may be difficult but whatever you do, make sure you purchase a remanufactured original HP OEM, not one of the all plastic designs with no black rubber bulb in the bottom of the printer. They fail and leak a LOT!.

Hope that helps..

Printing yellow for black


Hi Jan,

Can you confirm that you are using a CIS or non-HP cartridges with this printer?

It sounds a lot like the printhead has reached a clogging point where sediment has built up in the black portion and loosens enough to printer a few lines before it re-asserts itself again.

Based on my experience of this printer, if you're using a non-HP delivery system for ink then you should consider replacing the black ink with a dyebase alternative instead of pigment.. Replacing the Black/Yellow printhead and running a number of test prints to purge the pigment ink in the printhead should then result in a clean and more reliable printout in future.

One other vector for problems is the cleaning area and I've found that this can become soiled with excess ink causing cross contamination within the inks of one printhead. As yet I've not found a reliable solution to counter this sort of issue.

Hope this gives some clues and hopefully some ideas of a fix.

Changing the printhead


FYI: The L7590 doesn't have any tape on either the cartridge or the printhead.

Right couple of things here...

1. The printheads in the L7590 are either K/Y (black/yellow) or C/M (cyan/magenta)... There's no single black printhead unless of course this is not an L7590 we're discussing here.

2. The cartridges ARE individual with K, Y M C (Black, Yellow, Magenta and Cyan).


It's likely that the printer has one of the following faults.
  • Chip contacts and/or chips on the cartridges are soiled and/or damaged. Try checking for ink on chips and contacts in the cartridge bay

  • The little white oval pump in the bottom of the cartridge bay has become disconnect or broken. This is used by the printer to pump ink into the printhead but it also detects pressure variations and has a logic circuit which declares low pressure as "no ink".

If the problem is the latter then you need to get the printer serviced and/or repaired at a service center.

If it's the former you should be able to fix it yourself.

If you're using non OEM (ie: not by HP) cartridges I'd recommend getting a new OEM/HP one to test before you go for a service as some cartridges are just poorly filled and/or designed.

Hope that helps.
