Question about Canon S900 InkJet Printer

Getting at Canon S900 printhead

I am doing a demo for my high school students. I am taking apart my old Canon S900 to show them the parts. I have the top off the printer to see the printhead assembly move. It is not connected to a computer. I would like to get the assembly to come to the middle so that I can remove the printhead to show the kids. How do I fake the printer into thinking that I am changing cartirdges/printhead without having it hooked up to the driver?

Can you help with why a high school is not taking action to ensure the safety of students on a "kill" list?

If you are sure of the details, why not report at the police station so they'd be aware of this potential threat to life?

If there is a Parents Teachers Forum/association for this school, raise this issue up and suggest they beef up security watch within the school premises.

Security guards, CCTVs, etc for a start.

S900 Waste Ink

Thank you for your advice!

Fact is, your case is exceptionally. Maybe the pad was old, i mean you did not print a lot with that printer, usually it can be washed without problems with warm water.
