Pro-100 has gone blank

[dgerety]

Hi, all, 

My Pro-100 has been great, until today. It has plenty of ink and makes all the right noises and feeds paper slowly like always, but the paper comes out blank. I've run the standard cleaning utility, hoping for dots, streaks or anything...but the paper comes out as blank as when it went in. It's been a week, give or take a few days, since it worked perfectly. 

I haven't made any software changes. Wi-fi works properly and my Canon TS6320 works just fine. 

My computer is a Mac Mini running Mojave 10.14.6. 

What could make my Pro-100 go blank with no changes to anything? 

Many thanks for your time and suggestions. DG

Thanks, Patrick

I've run both cleaning utilities. The paper still comes out blank. I've shut it down and will give it 24 hours before trying something else. It seems odd that the print head would just die completely instead of giving some clues like streaks. If it's still dead tomorrow, I'll call tech support. Thanks again. David.

After a long talk with a Canon tech, I ordered a new Pro-200. I think a printhead replacement would fix it, but I'd rather not spend the money for one and then find it's something else. Just for kicks, I soaked the head for 48 hours in a mix of distilled water, alcohol and ammonia and then used a high pressure distilled water spray, but it didn't print even a hint of color. I need to use the new one weekly. Lesson learned. Thanks.
