Question about Office Equipment & Supplies

4 Answers

My Canon MP830 leaks an excessive amount of ink (comes out about the centre of where the paper comes out from under the print heads). Result ? the back of the printed paper looks like it has been dragged through a pool of ink (which is fair enough, because this is what has happened). I have installed a new print-head and new ink cartridges, but problem remains. There are no error codes, just this huge ink leak. A friend of mine suggested it could be the purge unit. Question 1. Are the symptoms consistent with a faulty purge unit? Question 2. Can you send full instructions with diagrams on dismantling MP830, replacing purge unit, testing operation before reassemble, and then reassembling? Question #3. Can you recommend where to buy purge unit for MP830? Thanks

    Thanks walesarumi,

    There is a HUGE amount of ink - it sort of "bubbles" out under the exit rollers and runs down into the paper out tray. It is just black ink (Not a mixture of colours).

    It emptied the PGI-5BK Black Ink Cartridge in a couple of days. I thought the PGI-5BK may have been faulty, so I replaced both the PGI-5Bk and the CLI-8BK cartridges (just to make sure I had the one leaking).

    The problem continued, so I purchased a new print head and installed (I think the problem has been caused by a metal cable-tie being jammed in under the print-head. I examined the old print-head under 80x magnification and noticed some ruptured sections, so I hoped a new print-head would be the answer - but unfortunately the ink still floods out).

    The ink is on the back of the sheets ? I think when they are passing over the excess ink, when they are coming out into the paper out tray.

    With this large amount of ink being present do you still think it is the ink not being absorbed into the ink pads fast enough?

    Cheers,

    PS. There looks like there could be a tube broken/disconnected from the purge unit (I can?t quite work out what it is).

You can send an email inquiry at the above link. I could not find any reference to a purge unit, unfortunately.

And, internal parts are replaceable, but you must call 1-800-OK-CANON to go further.

Hi,
The problem seems to be the purge unit but not sure until and unless it is opened. For your assistance, you can download the manual from the below mentioned link
http://www.retrevo.com/support/Canon-MP830-Multifunction-Printers-manual/id/259bh646/t/2/
As far as purchasing a purge unit I would recommend to get it from a retailer RadioShack, Wallmart or Best Buy. Online shopping visit eBay or Amazon.

    Hi,

    I understand that but if the ink is poured inside and not dried it will stain the papers. For that you have open the printer, clean the excesive ink leaked and also check the purge unit or for may broken pipes.

Welcome to FixYa
The purge unit is located all the way to the right where the printhead moves back and forth. You may be able to fix the error by first moving the printhead all the way to the left, then you can look in the right side with a flashlight and see what's clogging it up. Then, you can use q-tips to clean out whatever is blocking the purge unit.

Hello,

I don't agree with your friend, I don't think its the purge unit that is causing the problem. The problem is from the ink absorber.

During printing, ink does not get absorbed into ink pads fast enough causing a build up of ink on the platen roller and the exit rollers.

Canon techs are instructed to replace the ink absorbers with a modified kit that includes a silicon tube, plastic joint, and Mylar sheet. The shape of the waste ink pad has been changed to prevent the ink build up.

If you have a mind to do it yourself and your not under warranty you can purchase the blotter kits at http://beckscrs.com/partlist.php or any printer accessories shop/store within your vicinity.

Good luck.

I got error 6A00. model mp830


Hello i hope u 'll be fine.... thanks for using fixya.

The 6A00 is a Canon generic code for paper path jam.Some where in the paper path a sensor is activated indicating paper jam so the printer will give off a 6A00 code.As a Canon technology,I usually find the code almost 90% of the time it is related to the purge unit being jammed with something and not being able to move.Moving the print head assembly will not clear a purge unit if its jammed with paper,paper clips,push pins,screws,cookie crisp,flower bud pods etc.
I have found all those things in a purge unit.The offending item needs to be removed or the purge unit needs replacement.A
Canon PIXMA MP830 All-In-One InkJet Printer would still be under Canon warranty, get it into a shop and save yourself the hassel.
Incidentally, the 6A00 error pertains to all Canon printers made in the last several years, its not just used in one model & its always a paper path error or purge unit
I forget myself so here goes, the purge unit,called a spittoon assembly in an HP,lexmark & other ink jet printers,is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing.That is why you 'll find the print head assembly parked on top of it. It also has a an electrical pump to milk the print heads and test for ink flow

Returning an error 5200 on my canon MP830 printer


Hi
I have an MP830 on my desk I use all the time. Whenever I use generic cartridges I get the 5200 error and the A600 error. This seems to be caused because the generic cartridges ooze a little ink. The ink falls down into the excess ink pad (as it should) but it also provides a minute amount of resistance when the print head first starts to move which generates the errors. What I do once a week is take out all the print cartridges and clean off their bases. Then I take out the print cartridge holder and clean that. Then I move the print mechanism to the left side. I take a folder piece of paper towel that I put a little glass cleaner on and I run that over the excess print well on the right side of the print head travel or where the print head normally sits. Of course I do this with the printer off. So far it's worked every time. When I first bought the printer and I got the error message I called Canon and this is what they told me also. Since I've been troubleshooting electronics for 40 years I wasn't pleased with that response so I began some troubleshooting on my own. his is what I came up with. I hope this helps. Good luck

Black ink doesnt work it skips lines


Sounds like you need to change the head.
Mine recently did the same thing and I had purchased a new head a while back, so I installed it.
Worked perfectly. You can purchase it from Canon online.
Good luck.

Cannon Pixma MP830 - smearing on front when printing


If you have taken it apart that far then you are way ahead of the game. My suggestion would be to clean the head or anything the ink touches in a vinegar/water solution. The vinegar dissolves any dried ink whereas the soap may actually gum things up. If that doesn't work or improve things I would say that your print head has a seal problem. The replacement print heads are worth more than a new printer so you can probably figure out whats cheaper to do.

My canonmp830 printer is not printing in black ink


**Repeat from previous post. Would not print black. I went through all the troubleshooting of cleaning the printhead several times. The Nozzle check (found under Printing Preferences/Maintenance tab) kept coming out without the PGBK section (Black) printed on it. All the colors printed. If your see any of the colors missing, it is probably the same problem---it needs the Print Head replaced.
Part # QY6-0061-010. I was able to find it at Canyon Computer Supplies in Phoenix, but you can also order them via the internet from multiple outlets. Mine cost $59.57 with tax...much cheaper than a new printer. The replacement is very easy...Canon has info on how to do it at http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=123&modelid=12804#SupportDetailAct ...if the link doesn't get you right there, search MP830, Support & Service, then search print head & you should find it. Once you remove all the print cartriges (printer ON), the gray lever on the left side lifts up and releases the print head...which is the unit that houses all the print cartridges. I just put the new print head in, replaced all the ink cartridges, did a nozzle check...and it worked!! I love fixing things myself.

Cannon mp830 prints all colors but yellow


Your print head is likely toast.

The only way to be sure is to test out your purge unit (aka capping assembly).

This assembly provides the suction when you use the cleaning function. One test is simply to install a new oem ink cartridge, do a bunch of cleanings and see that it is actually emptying the ink out of the cartridge (look in the cartridge and see that the ink is being used up).

Since you said you have tried several cartridges, I would hope this means you know 100% for sure that the ink level in the cartridge is going down (you cannot rely on the level indicator in your driver software).

Since your purge unit is working, then your print head is either so clogged that the purge unit isn't strong enough to clean it, or the print head is defective.

Remove the print head and inspect the bottom. Give the bottom surface (and no more) a rinse under very hot running water. Blot the bottom surface on paper towel and see if there is any yellow ink coming off in the paper towel. If you can find a tube that will fit over the yellow ink well in the print head (the part that contacts the ink cartridge) try and force water through the tube and see if a fine mist comes out the bottom of the print head. If yes, then the head is not clogged. If no, leave the print head to soak for several hours. A saucer with a small amount of water in it will do. Just let the bottom surface of the print head contact the water (the cap off of a can of spray paint usually works for this)

Let the print surface soak for a few hours, or even over night. Reinstall the print head and give it a deep clean. If it still does not work, call your local Canon repair shop and check the price of a replacement head.
