Re: print head cleaning

The print head is the black plastic bracket at the back and bottom of the unit that holds the ink cartridges - it looks like one piece but its actually two. Remove the four ink cartridges and the just pull the back of the black plastic unit forward and lift out. There are no clips and it comes out effortlessly.

Re: print head cleaning

I have 5 print cartridges also. I took out the print head by first putting up the grey piece that holds the print head/cartridges in place. It has a handle on the right side.

Once I had done that I was able to take out the print head pulling it gently straight out the front. Don't pull on the entire carriage, just the print head inside it that holds the cartridges.

Re: print head cleaning

Cleans up well with IpA. In the uk you can buy from Maplins. In the US use windex. I wash the head in warm water first and then cleaned the head with ipa using cotton buds. No problem after that. ado

Re: print head cleaning

FixermanO - I tried to remove the print head from my MP780 but it doesn't seem to lift out easily for me. Am I doing something wrong? I notice that you mention 4 print cartridges and mine has 5 so wondering if you were using a different one?

Press the button on the right hand side of the printer. Lift the lid, pull up the little gray handle. Rock the print head container a bit and you'll see a little metal bar. Grab that and pull straight up.

Replaced black, would not print black, deep clean times two and still the same problem. What can I do?

Hi, the print head needs to be removed and washed with warm water, Please check the manual for print head removal and re-installation. Also print head alignment must be done on re-installation. The process sounds complicating but is quite simple. Do as if you are replacing a ink cartridge. When the print head is at centre in this process and stops.Switch power off on printer.Remove the cartridges, then remove the print head, wash in warm water carefully, do not use any brush or do hard rubbing, dab dry on paper towel. Replace print head into printer, then cartridges, then switch power on. Do print head alignment, clean print head once and print test pattern. Hope this helps as it has worked for me and is still working. All the best.

Remove print head canon mp480

THe print heads are an integral part of each cartridge. When you remove the cartridges you actually remove the print heads. You will need to open the top front panel to access the print carriage which moves left and right over the paper under it. Using cotton swabs you can apply rubbing alcohol to the places the cartridges rest upon and absorb all the dried out ink. Be sure you toss the old cartridges out before you reassemble. If you need to store any ink type printers REMOVE ALL CARTRIDGES and clean off the receivers on the print carriage!

Hi Good day!! Try to do a printer maintenance
Cleaning a Clogged Print Head

1. Press the cleaning button located on the front of the printer. Hold it down for 3 seconds to begin the cleaning cycle.

2. Run a cleaning cycle using your Epson printer utilities program. In Windows, go to "Start," "Printers and Faxes," right-click on your printer and choose "Printing Preferences." Select the "Utility" or "Maintenance" tab, depending on your printer model, and click "Head Cleaning." When the head cleaning cycle is complete, run "Nozzle Check." Repeat the head cleaning and nozzle check one to three times.

3. To access the Epson printer utility in OS X, select the Epson Printer Utility icon in the Applications folder in Macintosh HD. If prompted, select your printer from the Printer List, then click "OK."

Clean the print head manually. Remove the ink cartridges from your printer according to the instructions in your owner's manual. Turn off your printer. Dip a cotton swab in isopropyl alcohol, ammonia or hot water and rub the swab against the print head. Let the printer sit overnight.

Remove the print head according to the instructions in your owner's manual. Soak the print head for at least an hour in a small dish of hot water or isopropyl alcohol.

Preventing Clogged Print Heads

1. Use your printer at least once a week. Regular use will keep dried ink from clogging your print heads. If you have a color inkjet printer, print full color pages in addition to black-and-white documents.

2. Turn your printer off when not in use. This will prevent warm ink from bleeding onto the print head. If you have to store your printer, remove the ink cartridges.

3. Use a cleaning kit regularly. A cleaning kit usually includes a tube of ammonia that you spray on the printer head to clean dry ink.

Hi, (MX850) My blue ink has stopped printing. I

Performing Maintenance:

Note :
Be sure to install the ink tanks in the correct order indicated by the label on the Print Head Holder. The machine will not print if an ink tank is installed in the incorrect position.
Step 1
Printing the Nozzle Check Pattern.

If lines are missing or if white streaks appear

Step 2
Print Head Cleaning.

If the problem is not resolved after performing Print Head Cleaning twice

After cleaning the Print Head, print and examine the nozzle check pattern (Step 1) again.

Step 3
Print Head Deep Cleaning.

If Print Head Deep Cleaning does not resolve the problem, turn off the machine and perform another Print Head Deep Cleaning after 24 hours. If the problem is still not resolved and if you are sure that the ink didn't run out, then the Print Head may be damaged. Contact your Canon service representative.

Hope this helps.
All the best.

Epson 9600 print head missing numerous nozzels during test print procedure. Tried power clean several times. Do you have a remedy?

You willl probably need to clean the Pump Cap Assy.

You will need a strong flashlight/clip-on lamp to see what you are doing up in the area you are cleaning.

Move the print head to the left side of 9600. (If you need help with this let me know.)

Use a foam tipped swab slightly dampened with warm water to GENTLY wipe around the seal area of the Pump Cap Assy.


Dip, Blot, & Wipe. Clean the Foam Swab often to wash off the residue it will pick up. Remenber to keep the swab slightly moist - not dripping wet.
If this does't help, it generally means that the Print Head is also very clogged with gummy/dried ink.

The Print Head cannot be cleaned without removing the Right Side Cover & then removing the Pump Cap Assy. This removing and cleaning is about a 1.5hr-2hr job for an experienced tech. Anyone with moderate mechanical skills can do it though.

Pump Cap Assy cleaning is usually done BEFORE replacing the Print Head.

If the Print Head cleaning doesn't work then a New Print Head is in order.

Hope this helps ! Good Luck !

After being abroad for 3 months i can home to find printer not printing correctly i replaced the 5 ink cartridges but only 2 working Black and cyan

The ink has dried in the print head. If the print head comes out, remove it and apply rubbing alcohol or water with a paper towel to the nozels to disolve the ink. Once the ink seems to be fluid, replace the print head and ink cartridges, do a head cleaning and try printing again.

If the print head cannot be removed, get a childs medicine syringe, draw in some rubbing alcohol. Remove the non printing carts and apply a couple of small drops of alcohol to each ink port on the print head. apply some more drops to the ink port of the carts and replace and try a head cleaning and print.

If this does not work, continue to ask for help. The aim is to save the print head, not buy a new printer.

Open the top of the printer and remove all of the ink catridges. Be careful to place them upright and on top of some newspaper. Lift the lever to the left of the print carriage all the way up until it stops. It should come to rest staight up. You may now remove the print head by rocking it forward first and lift it out. Place the print head in a small container that does not allow for much room on any of the sides. Pour rubbing alcohol into the container and submerse the print head until the intake screens are covered. Gently agitate the container for a few minutes and remove the print head...placing it onto newspaper or paper towels. You may use a cotton tip applicator (Q tip) and gently rub each of the intake screen for each color. Turn the print head over and clean off the applicator portions of the print head (Copper looking with slots). Be careful to not leave any debris on any of the surfaces. Tap the print head onto the paper towel softly to remove any excess alcohol. If you notice a lot of ink still oozing from the bottom of the print head you may repeat the soaking and blotting process several times. After you are satisfied that most of the ink is desolved and dislodged from the print head, wipe all the suface with a clean paper towell to insure the contacts, etc. are clean. Replace the print head into the printer and lower the lever to lock the print head into position. Replace each of the colors in the correct locations and choose the deep clean option either on the menu of the printer or on the maintenance options on your computer (Start, settings, printer, properties, maintenance). Try the deep cleaning option to insure the inks are flowed through the print head and then print a test alignment page. If you still continue to have problems with some of the colors or streaking you may need to replace the print head. There are several companies on-line that sell this item and it runs $50 or more. I have refilled my own print cartridges several times and sometimes incur problems from using them too many they also may need to be replaced with new(er) cartridges.
