I am using the Epson stylus pro 400. I am having this from mlast many months and from then it is working without any problem. But from last week, I found that its speed of printing the pages becomes slower and slower. Other than this, it print the pages with red color effect on that. This is very strange as it suddenly started doing this. If someone can tell me that what is the problem and how it can be resolved. Thank you so much in advance.
