Question about Canon MultiPASS MP390 All-In-One InkJet Printer
Error ##334 suddenly came up on display! tell me what should i do
1. Press the "menu": Key
2. Press "Copy" Key
3. Press "#" Key
4. Scroll thru the menu headings until you come to "Test Mode" - 12th heading or select (-) as a short-
cut to the last setting.
4a. Press “Set” and the display shows:
Test Mode  – 
4b. Press “8” and the display changes to:
Test Mode  – 
***note*** you have to wait until the display changes
Then the display changes to:
8: PRINTER TEST
5. Then Press the "3" button and the display shows:
8 – 3 : EEPROM Clear
*** the display scrolls to  : INK COUNT
 : 2PURGE FLAG
6. Press "0" button – for INK COUNT
7. Press the "Stop" button
8. Press Off then On to set new changes.
9. Printer feeds a blank page after it is turned on again.
This should Reset the printer and remove the WRONG CARTRIDGE error and save you a few dollars.
Replace all the Ink Absorbers.
Reset the counter to zero.
Replace the printhead. QY6-0042-000 (now QY6-0064-000)
Should cost you about $54 if in the US.
This will only work a few times. Eventually, it will fail to reset
and you will have to replace the Printhead. I hope this helps.
