laser printer activating PIR

[ITGURU]

I have a laser printer which is in the corner of a room. the room has a PIR sensor in the opposite corner but on the same side of the wall.
I remotely print to the printer whilst away from home so they are there on the printer waiting for when I return home.
however on most but not all times when I print I end up getting a text saying the PIR in that room as been activated as intruder zone and sets off the alarm.Obviously paper moves and the printer generates heat but really?! Never had any false activations apart from when I print!
Sounds a bit daft but should that really be happening?!

The paper is what gets heated by the printer. Moving heated object = exactly what PIR sensors are designed to detect.

Replace the PIR for a Dual-Tec Sensor, wire like for like.

Move the printer so out of detected area.
You could mask out the side of the sensor that looks at printer,this is a last resort and not good practice.
Change sensor as already said .

Move printer

It's a Honeywell 8IR103 sensor currently

Put a upturned cardboard box over the printer.

Put a upturned cardboard box over the printer.

and then a fire alarm above the box.
