- Canon Pixma MP830
I have an Pixma MP 830 that up to now has been working very well with very little use since I bought it new when this model first came out. I got sick and tired of my Lexmark printers always acting up and decided to step up to the plate and finally buy something considerably more expensive and deluxe compared to the other junk I had in the past. When not in use I always unplugged the power cord and covered the printer. When i plugged it in this time and tried to turn it on or power it up it was totally dead. As mentioned on the internet before I found this forum was to unplug the printer, press the on/off switch while unplugged and then plug the cord back in and retry. Nothing happens at all. I downloaded the Canon service manual and removed the power supply and checked the connectors etc. All seemed connected properly. I brought the printer to a friend of mine who repairs Radio and TV and after checking out the power supply (and getting that damn screw out!) to check the fuses etc. he figured the power supply is okay. At this point he figured one of the boards inside may have died and didn't figure it payed to go through all the work of dismantling this beast that probably wasn't worth much anymore. After doing a great deal of googling I read about how a print head can either damage the main logic board or prevent the printer from powering on if defective. There were suggestions of disconnecting the print head and then turning on the unit and of course if it did power on it should display a defective print head code. Of course with this MP830 not powering on the print head is locked in the parked position. At this point they mentioned the printer would have to be disassembled in order to unlatch the print head and disconnect it. Using the manual I started carefully dismantling and opening up Pandora's box. I have only gotten to the stage where the top hinged cover, paper feed, side, front corner covers are removed. I examined all of the ribbon conductor connectors to the now exposed logic board. This is where I stopped, thinking If there is a print head malfunction and this possibly damaged the logic board how do I determine what i need? Because I did spend a fair bit on this thing and it is still in very good condition cosmetically this is why i'm still willing to try to resurrect it. I also noticed new print heads and good used and new logic boards are easy to find on Fleabay at very reasonable cost. If disconnecting the print head is the next thing to do, what is the easiest way to get to it to unlatch and disconnect without having a major basket case sitting in front of me?
