Question about Canon Pixma MP500 All-In-One InkJet Printer
This is actually a possible fix for error code 5C00 "purge cam sensor" where the purge unit has been replaced but still shows the same error code.
I found this by error but it might apply to other Canon printers.
I bought the printer off a well known auction site for a couple of pounds described as "not working does not power up when switched on" I soon found a wire unattached on the power adaptor plug and after soldering got error 5C00. I stripped the unit down and removed the purge unit to find it unused with no ink on the pads that touch the print head, it looked new. I checked the microswitches and sensors were switching/sensing reassembled the unit to have the same error, the purge unit was being driven by the motor correctly, the scraper bit was moving but the unit said it wasn't sensing. I started checking the wiring and that all plugs were in the correct sockets. they were all different except for two, the plug from the purge unit with 4 yellow wires, and a plug with same fitting but with 4 multicoloured wires. the plug from the purge unit at this time was just to the right of middle of the main board and the plug with the multicoloured wires was on the extreme right
somewhere around half way up. I swapped them over the plug from the purge unit and 4 yellow wires were now halfway up on the extreme right of the mainboard, hey presto it worked and the printhead now moved so I assume the multicoloured wired plug feeds the print carriage. The printer functions perfectly.
The person who stripped it to replace the original purge unit must have got the wires crossed.
Hope this helps a few printers out.
