My printer massage show open heat error.

what brand is your printer? Others may heat up if there not intended for a heavy usage like the deskjet. The proper way is to use a heavy duty printer that can support a high duty cycle, like laserJets. HP have the best laserjet ever made.

Open heat error

From looking at the manual it looks as if you have a faulty thermistor. When warming up, it has to heat up to at least 60 degrees. If it stays lower then 60 degrees celsius for over 35 seconds and doesn't reach 60 within that time frame then that would cause the open heat error that is happening on your machine.
