You cannot talk of effects of humidity on prints without mentioning Hygroscopy. Hygroscopy is a phenomenon where water molecules from the environment are attracted and retained. A paper is quiet hygroscopic so changes in humidity can affect its rigidity, weight and thickness. The effects of humidity on papers brings many issues especially where printers are involved. These effects apply to all printers including the Epson T200XL ink cartridges.
How does humidity affect the quality of your print?
High Humidity- When a printer is in a high humidity environment, the moisture affects the printing papers as earlier said. This, in turn, affects the normal functioning of the printer and cause, paper jam.
Secondly, the effect can cause smudging and steaks in the course of printing affecting the quality of the print.
Thirdly, high humidity can cause the papers to stick together and also cause the printed sections to be over saturated. The toner can also peel off from the page, leaving blank spots on the print.
Low Humidity- Lack or very low humidity can cause two or more papers to be fed in the printer at a time. When the paper is too dry it becomes more prone to static electricity. This can cause paper jam in the printer. Ink clogs within the printer and faded prints are a cause of low humidity.
To avoid poor printing from your Epson T200XL ink cartridges as a result of changes in humidity, it is advisable to regularly to measure and try to control humidity levels ranging between 40 % to 60 %. The amount of moisture in the air can be measured using a hygrometer. Add or remove excess moisture when needed. Excess moisture can be removed by use of air conditioners or a suitable heating system. Similarly, heating systems and air conditioners can be used to increase the level of humidity.
