kdaweso1,... Most of the time this problem is caused by ink splatter getting on the timing strip that runs the width of the printer and passes through the back of the Carriage/printhead ASM. If any ink gets on that timing strip it can give false locations in both the left to right and right to...

I have been watching this post for several days. I have also communicated personally with some of the individuals and they know that I have created very technical and detailed Repair Manuals for Canon Printers such as the i9900, i9950. This manual and the CD it comes on is all you will ever...

embguy,... Jerry1111,...Yes you are correct,... it has been many years since I did that job, in fact it was back in 1985. But this was not a little repair station to fix a defective card. This was a production line that could support the manufacture of 500,000 PC & Laptops a year. So it...

lin,... Thanks very much for your support on my comment. Sometimes after a few libations I tend to get very long winded. One additional comment,... If anyone out there ever has this type of PH problem, I totally discourage you from even attempting to remove and replace the decoder chip on the...

jflan,... I must admit I have not been keeping up the the absolute new editions of Canon printers nor the new chips that are supposed to be region coded. I now see that Canon must have surcommed to pressure from whomever holds the patent for the CD's printing forced them to curtail all...

Grandad35,.. Well it has been awhile but I finally got down to testing the "Reset the EEprom" solution. When I first saw this suggestion I felt that it would be "Logically Impossible" for the following reasons. 1. The EEpron in question is on the Main logic board and has nothing to do with...

jflan,... I have not done the iP4600 but I believe it is identical to the iP4200 and all the way up to the iP6700. All you have to do is go into Service Mode and change the "Country Code" to Europe. Once that is done, just power the unit off and the code will be reset. To test it, go back...

Bertil,... The iP4200 has a color resolution of 9600x2400 dpi which is twice that of the iP4000. If your concern is about fading of prints, then you are first going to have to get excellent photo paper and ink to match. You need to search for Archival quality in both. You should have a...

Bertil,,,, This is a strange place to post information and/or problems with various brands of ink. The MP730 is a work horse of a Multifunction machine and is very fast. It is based on the i850 guts and is as fast as the i560 printer. However, neither of them where ever the best for doing...

sxd, It sounds like either you have a leak in the Cyan ink cart that is flooding the park pads with Cyan ink. As the head sits there for any log period, the Cyan ink (if flooded in the pad) will WICK back up into the other colors. The purge unit is supposed to operate every now and then and...

This has really turned into a fantastic post with lots of great information. I have been using a similar cleaning approach for about 6 month,..but of course it is different yet. I took old Canon ink carts, cleaned them, dried them such that they were as good as new. Then I've filled them...

For those of you that have a Canon MP730 printer, The service manual has instruction on how to get into "Test" mode and from there you can go to 8 different sections. They do a terrible job in the Service Manual and they purposely don't tell you what each one of the sections really do. This is...

Many of you have seen some of the posts that I have made to this web site and know something about my Repair Manuals for Canon printers. I am missing the Service Manuals for several Canon printers and I would like to make a trade with anyone that has any manual that I am missing for one of the...

Tom,... The Stop/Reset button on the iP6600D is the same as the Resume button in all of the instruction. all other function work the same.

bedavids,.... If you don't know by now the cost of a new printhead for the i9900 is about $70. Now is the time for you to learn about cleaning your printhead as it will be the most important thing you need to know as long as you own your printer. Your description is very poor so run a nozzle...

popsy,... I'm sorry, I can't see one thing wrong with any of your nozzle check. So if you are getting bad photo prints, it is due to some other issue. Sometimes the problem comes down to bad ink carts. They supply enough ink to print a perfect nozzle check. which is what I see from your...

popsy.,... If you have tried a new printhead and new ink carts and still get the same results, I would suppect you purge unit. It could be excessive clogged ink, bad or clogged suction tubes, bad pump, stuck open valves, etc, etc. If the purge unit is not working, it can't such the correct...

Soporose,... Given the number of CD's that you've printed, I would assume that the bottom CD feed rollers are somewhat dirty and slipping. However, since you did not mention that you make sure to install the Tray with the CD in place all the way into the "Arrow" marks. This places the Tray...

Ron350,,.... I sent you an email and/or a post and I attached a picture of the complete Purge unit showing where the spring goes. I guess you didn't get it. I'm away from home now and I don't have access to my pictures but I will send it again when I get home.

LeslieK,.... I don't think you first Printhead was bad,... just had a difficult clog. Now that you have a new printhead, you should work hard to fix you MP730 and keep it. These are one of the best printers Canon ever put out. I have 5 of them that are many years old and they are still...
