Canon BJC-3000 Series User Manual page 23

Do not subject BJ cartridges or ink tanks to shocks or excessive vibration.
Do not touch the metal contacts on a BJ cartridge after printing.
I Using the printer near appliances such as fluorescent lamps
Allow at least 6 inches (approximately 15cm) clearance between the printer and an
appliance such as a fluorescent lamp. Electrical noise generated by a fluorescent lamp
placed too close to the printer may cause printer malfunctions.
This could cause the ink to leak out and stain your clothing or the
surroundings.
The metal parts may be very hot and could cause burns.
