Re: sharp mx 453 light prints and copies
Have you emergency stopped the machine yet to see if you're getting a properly developed image on the drum? =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: sharp mx 453 light prints and copies
I had an MX-365N with the same problem.
I backed up all of the settings and ran sim 67-17 to reset the machine to factory settings.
I then pushed the backed up settings back into the copier and had no more problems.Comment

Re: sharp mx 453 light prints and copies
These machines seem to not make the pm cycles using aftermarket drums and toner...Sorry they just dont. First I would check the high voltage output and adjust it to what you get in SIM 8. Next I recommend changing the dv and drum and mk kit all at once with oem stuff. MAKE sure to install the little clear seals that go on the front drum seal on each end. If you dont it will pull dv sooner or later. next clean or replace the transfer roller. I personally just wash them with warm water and a little tad of lotion free soap and then dry. clean the density sensor in the transfer unit while you have it apart along with the sawtooth grids in the unit. Then recalibrate the machine. 44-2 and then 46-24. If this doesnt fix it or it happens again.....replace the HV pwb and then do the hv adjustment as described in the manual.Comment
