Canon Printer MX310: I get an -30 error code; saying printer is not activated

SOURCE: Canon BJ-30 Bubble jet printer F-12 error

Hi, According to my BJ-30 & BJC-70 user manual, if F12 is blinking, it is required for this Error code to get in touch with a Canon Service Centre. I had this in the past and being curious I removed the printer chassis from case the and found the problem to be a loose ribbon cable in the connector on the main board from the touch pad circut board . I also had the identical problem with my BJC-70. These printers are very reliable and compact, it seems to be a problem which I think comes about from these printers being so portable. It took me about 15 minutes to fix the problem for which I have made a small modification to hold the cable in place. Having said this, it may not necessarly be your problem but it is a starting point. Canon to my mind have not made another portable printer this good, so if you value it and can find a trustworthy technician get it fixed. If you want further info contact me here.

HI,

Please the pixma off and open the lid.Now manually slide the cartridge-tray to the left.

Use a piece of tissue to clean the base-pad where the heads are stored.See if it is stuck in a kind of upward position and look if the mechanism that moves the tray is released if not then touch it and it will be loose. Remove all ink residue, move the tray back to its most right position and close everything.

Let me know if you still get the same error.

Thank you

Clive

1. Disconnect printer from AC power (take out AC cord or power off your power strip). Disconnect USB PC cable from printer.
2. Press and HOLD the POWER button (untill step 7).
3. Reconnect power cord (turn on power) to the printer.
4. The indicator should be green.
5. Press and release the RESUME button , the indicator should be orange.
6. Press and release the RESUME button again, the indicator should be green.
7. NOW Release POWER buttons.
8. NOW Connect the printer to PC (USB cable).
9. NOW...I opened "Printers" and saw that a "copy" of my printer (i250 or i350) had been made. Make that COPY your default printer and all should work...

error [6000] or light blinking 3 times is mean there is an error occurred in the LF encoder signal.
