<jats:title>ABSTRACT</jats:title> <jats:p>We present an analysis of all the archival high-resolution spectra of the narrow-line Seyfert 1 galaxy Mrk 335 obtained with Reflection Grating Spectrometer (RGS) onboard XMM-Newton. The spectra show rich emission and absorption features in low and intermediate flux intervals. We model the emission lines with the pion_xs grid and try to find any possible correlation between the properties of the emitting gas and the source flux. Current data do not allow detailed trace of the response of the line emitting gas to the X-ray flux of Mrk 335, but the flux of the X-ray lines is significantly less variable than the X-ray continuum. We also find that the warm absorber's properties are not correlated with the flux variability. From the latest XMM-Newton observation in 2019 December, we find that the photoionized emission and distant reflection components have not responded to the flux drop of Mrk 335 from 2018 July. However, the possible existence of partial covering absorber in the 2018-2019 low state of Mrk 335 makes it difficult to constrain the scale of the emitting gas using this lack of response.</jats:p>
