What does ##343 mean?

##345 is jammed cartridge error. Reasons could include:

-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.

Symptons are:

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

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

Long fix:
The following operation takes several hours / days to complete.

-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.

-Mark all wires that look the same (especially white flat ones), take photographs when disassembling.

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

The two sponges are between metal frame and base plate, they absorb excess 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 out-coming water is clear, then it is clean.

-Let it to dry for couple of days, but you can use your imagination - compressed air could help it dry faster.

-Assemble it back together

How to reset waste ink counter (you should clean the printer also):

*AF-Key = Additional Functions key = the black button with the star in a head above it.

1) Enter SERVICE MODE. (Press AF-Key, followed by "scan", "copy", "scan" -Keys)
2) Select TEST MODE (press right arrow button 13 times).
3) Hit -OK-
4) Select [8] PRINTER TEST
5) Hit -OK-
6) It'll now say "- 8-2 +" press the right arrow key once to get "- 8-3 +"
7) Hit -OK-
8) Select 0. [INK COUNT].
9) Hit -OK-
10) It should return to showing the "8: Printer Test - 8-3 +"
11) Press the [Stop/Reset]key - (black key with triangle and circle on it) - (returning to the state of 4), and then press the [ON/OFF] key.

Cleaning the print head:

At any time, DO NOT wipe the actual print head with your fingers. Use ONLY water.

-Remove print head assembly from printer.
-Remove ink tanks.
-Use running warm water, wash away the excess ink that is dried around the print head.
-Take one disposable mug, fill with hot water, drop the print head assembly in there, and let it soak for an hour, or so.
(-IF you have massaging shower head, with spray jet -function, use this to deep clean the actual print head.)
-Dry it up carefully, do not wipe actual print head, just tap gently with soft paper.
-Install ink tanks, install assembly to printer, let it settle for some time (5-30 minutes)
-Run Nozzle check, cleaning, print head alignment.

This should do the trick.

Error 345

That error is very vague, even the manual says it's an internal unit malfunction, and you should remove and reinstall the printhead, clear any paper jams, and cycle the power off and on. When it doesn't help you need a new control PCB and it's more expensive than a new printer.

On the screen appears "check printer" and then "##345"

345 says paper jam or printhead problem, press continue, remove any jammed paper, try re- installing the printhead, the error is an internal communication error.

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

My mp360 shows ##345 on display,with alert light flashing.No information in manual,is it something simple or do I throw it in the bin?

That error is either the ink absorbers are full and need changing and a reset, or the purge/cleaning assembly is gummed up with ink. around $100. to $150 shop repair. Good machine with cheaper inks, probably worth the repair.

I got the Canon ImageCLASS MP360. It's not working because the cartridge jammed, ##345 showed on the screen. Once I turn the printer on, then I can hear loud noise like the cartridge stuck inside the gear....

Hello Dear,
Cause: The printer's internal unit has malfunctioned.
(1) Remove the jammed paper. (Check the paper edge sensor is OFF.)
(2) Press the [OK] key.
(3) Reinstall the printhead.
(4) Turn the power off and on.

If doing this solves you problem then ok or update me the status after doing this.

Hi, Apparently that error code means that the the cartridge is jammed, check that there are no bits of stuff stuck there and try to maybe remove the cartridge and maybe if you have any realigning software run those on it.
There seems to be a lot of people with the same and similar problems and the Canon service tech didn't seem to know what to do, and most are out of warranty too.
Let me know how you go.
