Magenta Ink Partial Printing

I have replaced cartridges, cleaned repeatedly, and still cannot get the Magenta ink to print. The black, cyan, and yellow are strong.... I always use Brother cartridges and have new ones currently installed. Should I spend the $60 and go to the service center to fix this problem ?

Re: Magenta Ink Partial Printing

Try cleaning the contact pads in the print carriage behind the cartridge with the eraser on a pencil. Also clean the ones on the cartridge for good measure.

This issue will only occur if an ink cartridge(s) is or was installed inthe wrong position (slot) in the machine. When a cartridge is installed, the ink tube system is filled with the ink from the cartridges, to prepare the machine for printing. If the cartridge is inthe wrong position the tube will fill with the wrong color.

NOTE: If you just installed or replaced the ink cartridges and your printed documents are missing colors please refer to the solution - I just installed or replaced my ink cartridge and my printed documents aremissing colors. What can I do? Blank

To resolve this issue you will need to clean the print head.

NOTE: It may require 10 to 15 cleanings to clean the ink tubes and print head. During the cleaning process, the ink in the cartridge(s) will be consumed. Additional ink cartridges may be required to completethe cleaning process.

1. First verify the position of the ink cartridges:

a. Open the ink cartridge cover and check to make sure the ink cartridges are in the correct order.

b. Starting from the left side, the correct order is Black, Yellow, Cyan(blue), and Magenta (red).

- If the ink cartridges are installed in the correct order, close the ink cartridge cover and continue to STEP 2.

- If the ink cartridges are not in the correct order, remove the ink cartridges that are installed in the wrong position by pressing down on the release lever(s), located above the ink cartridge and remove the cartridge(s) from the machine.

Next, reinstall the ink cartridge(s) in the correct position in the machine by gently pushing the cartridge in until it clicks.

When all the cartridges are installed, close the ink cartridge cover.

2. After closing the ink cartridge cover, the LCD will prompt - Did youchange XXXX (XXXX = the color) This message will be displayed for ink cartridge that was removed. Press the - (Minus Key for No). This willkeep accurate data of how much ink is left in the cartridge.

1. Press the INK key.

2. Press OK to select Test Print.

3. Press OK to select Print Quality.

4. Press the COLOR START key.

5. Review the Check Sheet. The colors on the Check Sheet should be in a specific order: Black, yellow, Cyan (Blue) and Magenta (red).

a If the colors on the Check Sheet are in the correct order and are notmissing any dashes, press + (Plus Key for Yes) on the key pad and continue to STEP 7.

b If the colors on the Check Sheet are not in the correct order, are missing dashes or blank or a color other than Black, Yellow, Cyan or Magenta printed press - (Minus Key for No) on the key panel and continueto STEP 6.

6. The machine will need to perform cleanings to flush out the incorrectcolor or dried ink from the ink tubes and print head.

a. The LCD will ask you BLACK OK. If black is fully printed and is the correct color, press + (Plus Key for Yes). If it#s blank, missing dashes or is the incorrect color, press - (Minus Key for No).

b. The LCD will ask you COLOR OK. If any of the 3 colors (yellow, cyan (blue), and magenta (red) are fully printed and are the correct color, press + (Plus Key for Yes). If it#s blank, missing dashes or is the incorrect color, press - (Minus Key for No).

c. The LCD will say START CLEANING + for YES and - for NO. Press + for YES to start cleaning. The machine will go through a cleaning cycle that will take approximately one to two minutes.

d. After the cleaning is completed, the LCD will say PRESS START. Pressthe BLACK START key. This will print out the print quality check sheet again for you to check and see if your print quality issue has been resolved or not

NOTE: If you wait 1 minute after the cleaning cycle is completed, the display will return to date and time. You will need to go back to STEP 3 to print the Print Quality Check Sheet again.

e. If the ink color order is correct and all of the dashes are present, press + on the key pad to select YES and continue to STEP 7.

If the colors on the Check Sheet are not in the correct order, are missing dashes or blank or a color other than Black, Yellow, Cyan or Magenta printed press - key to select NO. Repeat the cleaning process byfollowing STEPS 6a through 6d. You may have to perform this procedure up to 15 times in order to clean the ink tubes and print head

NOTE: During the cleaning process, the ink in the cartridge(s) will be consumed. Additional ink cartridges may be required to complete the cleaning process.

7. Test by printing the document that had the reported problem (wrong color printing).

I am having a problem printing with my HP printer

you wasted your time using cleaning program and heaps of ink...

follow this procedure:

1. remove all ink cartridges from the printer
2. check if ink is soluble in water, isopropyl alcohol or methylated spirit (this which do not create lumps or precipitations is correct solvent)
3. put one drop of solvent in th centre of aspiration hole on receptable
4. if solvent is absorbed through input, that meant problem is not with printer but with cartridges.
5. check printer cartridge by stamping them with tissue if they "produce" any ink on the outlet,
6. put one drop of solvent on cartridge outlet and insert them in correct bases
7. print test page, print should be rather weak as solvent will go through the nozzles
8. print test page from computer
9.create "strip page" of each colour used, separate by no colour (white) start with yellow strip, then white, light cyan, white, cyan, white, light magenta, white, magenta, white, black - this strip pattern will force all cartridge to operate on they max delivery.

if there is no result, service by technician will be in place...

all ink based printers need to print at least one page per week... ink will dry pretty fast, especially in dry or hot condition.

I replaced an ink cartridge because the printer stopped working and showed a message that the old cartridge is empty. However after putting the new one in but the printer still refuses to work and shows...

maybe the cartridge is wrong, release it and clean the electrical contacts, put them again one by one, if notting happen, try this
Solution As the printer operates, it moves ink from the ink cartridges into a printhead reservoir. The printer does not deliver a message when an ink cartridge goes empty, because it still has ink in the reservoir. The printer continues printing until the ink level in the reservoir falls to a first trigger point - then a message appears advising the printer owner to Replace Cartridges Soon . At this point, other cartridges that are empty but have not reached the trigger point are also mentioned in the message, to save trips to the retailer. After the first trigger point, the printer can continue printing until ink levels in the reservoir reach a second trigger point. At the second trigger point there is only enough ink left to perform vital servicing tasks, and a new message appears, saying Ink Cartridges Empty . The options offered depend on the usable inks remaining. If no options are offered, the cartridges indicated must be replaced before printing can continue. The Ink Cartridges Empty options are described in the table below: Ink colors out Option Print mode possible All Cancel None Black


Cyan, Magenta, or Yellow (any or all) Black only Continue with other colors Cyan/Magenta/Yellow mode (composite black)

Text and photo quality will differ from those printed when all colors are available Light Cyan or Light Magenta (either or both) Cyan, Magenta, or Yellow (any or all)

(Black still available) Print with black ink only Grayscale

To replace the ink cartridges
1. Make sure the HP All-in-One is turned on.
2. Open the ink cartridge door by lifting from the front center of the device, until the door locks into place.
3. Squeeze the tab below an ink cartridge to release the latch inside the HP All-in-One, and then lift the latch.
If you are replacing the black ink cartridge, lift the latch on the far left.
If you are replacing one of the five color ink cartridges, such as yellow, light cyan (blue), cyan, light magenta (pink), or magenta, lift the appropriate latch in the center area.
4. Pull the ink cartridge toward you out of its slot to remove it.
5. Remove the new ink cartridge from its packaging, and then, holding it by the handle, slide the ink cartridge into the empty slot.
Make sure that you insert the ink cartridge into the slot that has the same shaped icon and color as the one you are installing.
6. Press down on the gray latch until it clicks into place.
7. Repeat steps 2 through 5 for each ink cartridge you are replacing.
8. Close the ink cartridge door.

re Printing in black only - you can do this by selection this option from your application and choosing the print properties of the printer and setting to Black / Greyscale printing only.

IP4300 only recognizes magenta OR cyan

1. Get compressed air
2. Run Printhead under HOT water, do not worry about contacts getting slightly wet.

3. Blow compressed air with straw attachment into screens where the cartridge nozzle sits on printhead. then let it sit and dry.

4. reinstall print test page

5. if this fails open paint/photoshop and print a page of the color that is not printing correctly. rinse and repeat until colors flow freely.

I have several ip4300s and I have yet to give up the ghost on a printer with a clog ujsing this method.

Canon i9950 prints green on photo paper

I had the same problem. Having checked other websites I came across the following which narrowed down the problem to the Photo Cyan / Photo Magenta ink tanks, and replacing the Photo Magenta one (although it was not empty) has successfully resolved the problem. Eveidently ink from the original one was not flowing and so caused the syan cast. (I experimented by subsequently removing the Cyan one which produced prints with Magenta cast)


That post is labeled "Cannon (sic) S9000 Print Head" and concerns a greenish hue error in all print quality levels OTHER THAN plain paper. In other words, all output designated as Photo Paper Pro, Glossy, High Resolution Paper, etc., results in output with enormous and unacceptable levels of green hue. All output designated as "Plain Paper" whether the output actually is on plain paper or photo paper pro, turns out well.

This problem is not unique to the S9000, as I experienced it identically with the S820 and predictably can occur in any printer with the six cartridge print head.

It is a frustrating problem because you know that the printer is physically capable of printing WITHOUT the hue (as it proves to you each time you choose a "plain paper" paper setting.)

Troubleshooting by reinstalling and updating the printer drivers, and uninstalling/reinstalling the ZoomBrowser EX, replacing the ink cartridges, and deep cleaning are all blind alleys.

A call to Canon support solved the problem for me with this simple and important revelation:

The Plain Paper setting is unique in its use of only 4 of the 6 cartridges. In the Plain Paper setting, only the black, cyan, magenta and yellow cartridges are utilized. The Photo Magenta and Photo Cyan are not utilized. In all higher resolution settings, i.e., in all other settings, all 6 cartridges are utilized.

It follows that if one's problem disappears when not using these two Photo cartridges (i.e., when printing at the Plain Paper setting), then the problem lies with these cartridges.

(In my case, I'd loaded a plain "Cyan" cartridge in the "Photo Cyan" slot during earlier trouble shooting and had forgotten to replace it with the proper Photo Cyan cartridge.)

Problems with magenta hues would admit of the same solution.

Hope that helps anyone else out there tearing out their hair trying to troubleshoot this. "

Very Faint Printouts

I find the best way to clean the heads is buy some cleaning cartridges as they have cleaning fluid in them and use them to clean it will take about 10 or more times to clean the heads then put the color ones back in and try again.
Just keep putting it on clean the head don't do a print out till at lest you have cleaned 10 or more times.

Prints only green predominently

Without knowing what printer you have or what things you have tried I can only guess here. It sounds like you need a new cartridge. A color ink cartridge will have 3 colors of ink for most printers...cyan (blue), magenta (purplish-maroon), and yellow. Depending on what you print it is very possible that you could run out of one of the inks before the others. Printing green can be an indication that you are out of magenta ink. The cyan and yellow inks will combine and look green.

You can remove the cartridge and run a tissue over the printhead and see if you see all 3 colors as a quick test. If you only see cyan and yellow, then the magenta is probably empty or dried up. If you see all 3 colors I would reinsert the cartridge and try printing again. It is possible that the magenta was just clogged and you cleaned it with the tissue. If it still doesn't print all colors your best bet is probably to just get a new ink cartridge.

Magenta printing as yellow

Well, first off, are the alignment, and nozzle check sheets looking good? If not, then work on that. If so, then we have a problem. Try creating a test sheet in Word. Make red, yellow blue & black text and see if anything else prints wrong. Get back to me!
