UPDATE: It seems the MICR markings do not like the fuser temps that are currently set in the printer. I'd like suggestions or ideas on what settings to use for the fuser based on the following parameters.
The fuser is currently factory set.
The ambient temperature usually sets between 70-75F.
The relative humidty is rather high at times, between 75-85%.
The checks are oftentimes stored in the same room with the printer so they are exposed the aforementioned environment.
I've made suggestions about getting a dehumidifier and storing the loose papers in trash bags to reduce exposure, but reducing the fuser temps is a good start, but how low and what settings?
