    Following my return from vacation for a week, the screen said "incompatible toner." When I turned it off and back on, the printer now says nothing in the screen area, and is unresponsive.

Replace all electrolytic capacitors in power supply section on mainboard. caused by poor quality lower voltage caps being used in powersupply. Problem will reoccur every 2 to 3 years if 105oC caps are not used. If mainboard is replaced with new mainboard problem will reoccur within same timeframe. Fix old mainboard using higher voltage and higher temp caps and problem will be gone for good.

My cannon MX320 printer light are flashing both the on and alarm button - message contact service center, printer error has occurred at the botton of the sceen it shows B200


This error refers to a voltage problem within the print head. Usually the fix is a new print AND the main logic board.

Personally i feel its an end of life error and you should consider replacing the machine as the cost of repair is more than it would be to buy a new printer.

Sorry

Have you installed a new toner??? It may take a few minutes for the copier to add enough toner to make a copy. It's been awhile scince I've worked on one... But I think if you turn it off and hold down the Clear/Stop botton when you turn it back on, it will make the copier add toner... It looks like the display i chashing a box in the display. Good Luck
