 | Canon Pixma MP750 - disassembly guide by Bordobob (4/26/08 8:37 AM) reply | + / - | It's time to change the waste ink absorbers and I'd be more confident disassembling the MP750 with a technical service manual at hand...a step-by-step disassembly guide like the one I used to fix my Epson C82 (for the same reason.) Can anyone direct me to a source where I can get a 'real' tech service manual (not the unhelpful 'error code list' doc that says one should contact a Canon service facility...)?

| Re: Canon Pixma MP750 - disassembly guide by trigger1937 (4/27/08 10:17 PM) reply | + / - | Bordobob,... I have created Repair Manuals for most all of the Canon printers and a few of the HP printers. From time to time I list these Manuals for sale on eBay. Each manual has 9 chapters that deal with every thing from diagnostics, disasembly, repair, and preventive maintenance. I use high quality digital photos that show each and every detail on how to take apart and repair a printer, including things like how to reset the waste ink counter, remove and repair the purge unit, correcting the paper feed timing gears, and a lot more. All of this is in PDF format such that the digital pictures can be enlarged to 500% so you can see real close up details.
I also include the Canon Service Manuals and Parts Catalogs, when they exsist, and section that contain Color test images to calibrate your monitor and printer. It also contains section to SHOW you how to modify the Canon ink carts so you can refill the ink yourself and say and enormous about of $$$. These typically sell for $25 which is a great price when you consider that others are selling the Service Manual alone for $10. My CD also contains all the available documentation and software for the specific printer. I should have them listed again is a week.
There is no better manual anywhere. I hope this answers your question.

 | Re: Canon Pixma MP750 - disassembly guide by Bordobob (4/28/08 12:02 AM) reply | + / - | to trigger1937...thanks for responding ! However, after having posted at another site I received the service manuals in pdf and have already looked them over. True, they are somewhat limited in pictures on the disassembly but I think the instructions are sufficient. Your offer at $25 appears a "good deal" since another seller on the net wanted $40 just for the basic manual and error code list(of little practical value)and certainly no pictures. Having an experience on the Epson, I am going to use the docs that I received, but I'll keep in mind your offer if I don't succeed. Thanks again for your response.

Have you got any of these manuals on Ebay now - I want one. Have you got a auction reference number you can provide?

It is TRIGGER 1937 (this forum) who proposed a $25 CD package for the MP750 and I believe that he might have them available on E-Bay. I received a pdf manual from "info@continuousink.info" which I used to find the screws to disassemble the modules and clean the ink absorbant pads. I stupidly broke a wiring connection and am now attempting to repair it. Patience and good luck!

| Re: Canon Pixma MP750 - disassembly guide by Bordobob (11/3/09 11:08 PM) reply | + / - | Roy...I've received a notice from this old thread about your need for a repair manual for a MP530. I think that I still have one for MP750 only. In any case I gave up trying to repair the MP750 about 2 years ago and bought a Kodak ESP-3 which I use continuously. (I paid 1/3 the price for the Kodak and get the same functionalities ...)

| Re: Canon Pixma MP750 - disassembly guide by gigerfan (3/9/10 9:33 AM) reply | + / - | Okay... here goes. I first admit that I bit off a bit more than I could chew.
I acquired an MP530 that was jamming from the lower tray. Found that a spring, just under the upper paper tray, had come loose in the transport path and was blocking the paper.
Using the Service manual, it was a piece of cake to disassemble to get to the paper feed unit. But there were no exploded views of the unit itself (not even in the Parts list). I did manage to get to the spring and relocate the loose end.
but... of course ... phone rings in the middle of it all, and half the gears on the right side hit the floor.
I got most of the unit back together. Now I'm at a loss as to where the remaining gears go.
Anyone have access to the assembly diagram of the paper feed unit so I can finish this little matter and can clear my shop bench.
Thanks for any assistance.

| Re: Canon Pixma MP750 - disassembly guide by trigger1937 (3/10/10 9:09 PM) reply | + / - | gigerfan,.... You have discovered the key problems with people that purchase the Canon Service Manual and expect they can fix their printer. It basically shows you how to get the covers off and that is it.
I don't know what you were taking apart when the phone rang,..but there is no way you should have disengaged any of the gears. You would have to take the main carriage shaft loose to have those gears come off.
Anyway,... if you need more help, just click on my USER ID and send me an email. I will respond.

| Re: Canon Pixma MP750 - disassembly guide by philly5706 (3/10/10 9:15 PM) reply | + / - | trigger........I have to difer with you on this. I have the Parts & Service
manual for this printer and it is a complete manual of 175 pages and tells much more than dissassembly instructions.

Yes they do provide a lot of information and some of them even show you how to take things apart. However the Canon MP750-780 Service Manual does NOT include any pictures or instruction on how to take the printer apart. The Parts catalog only shows "Exploded Diagrams" to identify the major replaceable parts. What they don't show you is how to remove the covers and;
1. How to clean your printhead and why it needs cleaning.
2. How to clean and refill your Canon ink carts with GOOD ink.
3. How to clean your purge unit, and the bottom side exit tubes.
4. How to remove and replace your purge unit.
5. How to remove and/or clean or replace your timing strip.
6. How to remove and replace the carriage assembly
7. How to remove the main chassis from the base
6. How to remove and clean the Waste ink pads
7. How to remove and replace the main drive belt
8. How to align the feed gears.
9. How to remove and clean / or replace the timing disk.
10. What to remove and what NOT to remove in Disassembly
11. And on and on and on.
12. Finally,.. how to take care of your printer so it will last
forever.
Add to all of this are detailed pictures that show you step by step so you can not only get it apart,..but put it back together.
Maybe the most important step is how to test your printer when it is APART, so that when you put it back together you will know it is going to work.
I have every Canon Service Manual and Parts Catalog printed and believe me I have gone through each one in the process of creating a good Repair Manual for 45 different printers. If you want a sample of one of them, just click on my USER ID and I will provide it.

| Re: Canon Pixma MP750 - disassembly guide by philly5706 (3/11/10 12:26 PM) reply | + / - | trigger- The manual is for a printer tech and assumes that you know about printers beforehand. To a novice, it may seem daunting but to a tech it provides invaluable information.

| Re: Canon Pixma MP750 - disassembly guide by trigger1937 (3/11/10 5:00 PM) reply | + / - | philly,... you are correct, they are intended for Tech support people, and that is why they are not much help to the everyday people who don't know anything about printers. The Canon Service Manuals are a godsend, and that is why I GIVE both the Service Manual and the parts catalog away for free to everyone who gets one of my manuals. I also provide on my CD, folders that contain the latest versions of Acrobat Reader, which is necessary to display the manual, a folder for 57 Color test images which are used to test the printer under all conditions, to purge and clean specific ink nozzles, and to help others learn how to calibrate their printers and to educate people on the difference of subtractive color pigments as opposed to Additive color images. I also provide the full content of all software that was originally supplied by Canon, as well as all of the updated software, user guides, and setup information. All of this I provide at no cost. The only thing I charge for is my own Manual that I have spent years creating.
The final key item I provide is my unlimited technical support for each and every manual I sell, up until the time I die, or I become so senile that I forget the knowledge I learned. That may not be to far in the furture.
This is not all that is included but if your interested I will send you a sample.

| Re: Canon Pixma MP750 - disassembly guide by bordobob (3/12/10 4:05 AM) reply | + / - | gigerfan...screwing up a wiring connection or dropping stuff on the floor is par for the course among us non-techs. Even if you have the manuals,which I do,the disassembly and reassembly could turn out disastrous. I had a good experience on an Epson printer but still messed up on the MP750. Purchasing trigger 1937 's package, rather than relying solely on a manual and a bit of experience, seems to me the better way to go...that is, if you absolutely need the printer. If not, all you need is a hammer,a screwdriver, pliers and a case of beer...the manual will only get in your way.
