How to repair Canon SmartBase MP360, flashing error code ##345

Short: Take apart and wash the ink clogged mechanical parts. Use hot water.

What to do (Long version):

First, use your head!

Dont rush, this operation takes several hours / days to complete!

-Mark all wires that look the same (especially white flat ones), take photographs when disassembling, or use photographic memory :P

-Take apart the whole printer, so there is only a metal frame left, with couple of paper-rollers, and motors, and the "Print-head cleaning" -system. Wash this cleaning-system.

In detail, remove at least following items:
-Main Power lead!
-Casing (Use brigh flaslight to see TWO front cover-screws under the dark plastic!)
-Scanner (BEWARE of fragile flat-wires)
-Main electronic controller board
-Some other shit, metal plate, plastic cover, you will see.
-Plastic base plate
-All materials that might absorb water. (two sponges, and one rubber foam part)

The two sponges are between metalframe and baseplate, they absorb exess ink. Wash these separately, and dry, or change for new. (I left the shorter one out, when assembling)

There is also one long rubber foam part that is near where paper comes out, (visible from outside the printer, when cover is opened).

To get rid of the excess ink: Wash dirty parts heavily for 10 to 15 minutes with hot water. When outcoming water is clear, then it is clean.

-I let it to dry for couple of days (on heated floor), but you can use your imagination, compressed air could help it dry faster.

Assemble it back together, and it works.... at least MINE did xD

Not exactly shure, WHY this helped, but i think it had something to do with a LOT of dryed ink in the "Print-head cleaning" -system. --> parts could not move freely. Or maybe some sensor was dirty? OR is this just a coincidense, and I happened to fix some other problem while taking the printer apart?

If you have no idea what youre doing, then don´t do it. But its broken anyway , what do you have to lose?

Have fun.

Alarm button flashes, check printer, press OK .Error 6A00 appears, Pixma MP 750

The 6A00 is a Canon generic code for paper path jam.

Solution 1:
Move the printhead carriage back and forth a few times.

Solution 2:
Check the purge unit: 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 or the like.

Solution 3:
Press the ink pads down in the purge unit.

Receive message 345 and alarm which prevents operation.

Other Canon models "may" be repaired with these instructions also, for example MP370, MP390, etc. Try with your own risk.

-Grinding noise (very loud)
-Flashes error code ##345

Error code ##345 = "BJ cartridge head cleaning error" -reasons for this are:
-Foreign material or dried ink in head cleaning unit (also known as "purge unit") , or waste ink pump jammed up. Make sure waste ink pump rotates freely, after cleaning. Clean the waste pump-hose too! Waste ink pump is located under head cleaning system.

Short solution:
1.Take apart and wash the ink clogged mechanical parts. Use hot water.
2. Reset waste ink counter

purge unit: HM1-0723-000

Flashing E3 error code for a paper jam

I had the same problem with my mp 160, Error message was blinking. I tried to print but the printer would take 1/10 of the whole page and stop, even though rollers were moving. My solution for this was to take a piece of thin cardbord(I used a magazine cover), cut it in a size of A4, put it in printer, printed it and when the rollers start moving I forcebly pushed the cardboard through. Now it seems to work fine. Hope it does for you.
