[eliaso]

Hi all ,I have the hp mfp laserjet 1415 with original toner ,but the calibrate is bad ,
can someone have an idea about this color hp problem

When you say original toner, do you mean OEM toners or the actual starter cartridges they come with?

Toner cartridges are responsible for a LOT of calibration problems with these. But after the toner, it's generally the transfer unit.

But there's a registration calibration sensor you want to clean also.
